Hydrology of the Arbuckle Mountains area, south-central Oklahoma  

USGS Publications Warehouse

Rocks that make up the Arbuckle-Simpson aquifer crop out over ~500 mi2 in the Arbuckle Mountains province in south-central Oklahoma. The aquifer consists of limestone, dolomite, and sandstone of the Arbuckle and Simpson Groups of Late Cambrian to Middle Ordovician age and is about 5,000-9,000 ft thick. The rocks were subjected to intensive folding and faulting associated with major uplift of the area during Early to Late Pennsylvanian time.

Multiple episodes of dolomitization in the Arbuckle Group, Arbuckle Mountains, south-central Oklahoma: Field, petrographic, and geochemical evidence  

Microsoft Academic Search

The Cambro-Ordovician Arbuckle Group in the Arbuckle Mountains, south-central Oklahoma, had a complex history of dolomitization that resulted in two different geometries of dolomite bodies: stratal dolomite, of stratigraphically consistent, widespread distribution, and non-stratal dolomite, of stratigraphically inconsistent, local occurrence. Stratal dolomite includes the Royer and Butterly units in the lower Arbuckle Group. Most stratal dolomite samples are coarsely crystalline

Variation of oil composition in vicinity of Arbuckle Mountains, Oklahoma  

SciTech Connect

Fifteen oils in an 8-county area in the vicinity of the Arbuckle Mountains were classified into 6 oil types: stable platform type, Mill Creek syncline type, Joiner City field type, Gloeocapsamorpha type, Hoover field A-type; and Fitts field type. The stable platform, Mill Creek syncline, and Joiner City field types have a common element (diminished C/sub 32/ hopane) and are thought to be derived from distinctly different facies of the Woodford Formation. The Viola Limestone oil is typical of oil generated from Ordovician rocks. The Hoover field A-type has an element of Ordovician composition and is thought to have been derived from an Arbuckle Group shale. The Fitts field oil has a unique composition and has not been assigned to a source. The variation of oil composition in the vicinity of the Arbuckle Mountains is attributed to (1) the large number of potential source rocks, (2) the variety of facies going from the stable platform into the southern Oklahoma aulacogen, and (3) biodegradation of oils in shallow reservoirs.

The Cambro-Ordovician Arbuckle Group in the Arbuckle Mountains, south-central Oklahoma, had a complex history of dolomitization that resulted in two different geometries of dolomite bodies: stratal dolomite, of stratigraphically consistent, widespread distribution, and non-stratal dolomite, of stratigraphically inconsistent, local occurrence. Stratal dolomite includes the Royer and Butterly units in the lower Arbuckle Group. Most stratal dolomite samples are coarsely crystalline and have {sup 87}Sr/{sup 86}Sr ratios similar to Late Cambrian limestone and coeval seawater. All stratal dolomite and Arbuckle limestone samples have low {Delta}{sup 18}O values. Nonstratal dolomite is present in two areas: the Tishomingo Anticline and the Arbuckle Anticline. In the Tishomingo Anticline area, massive bodies (> 10 km{sup 2}) of nonstratal dolomite are present in a paleokarst system of pre-Middle Ordovician age. The petrographic and isotopic characteristics suggest that the nonstratal dolomite probably resulted from dolomitization of recrystallized limestone by post-Early Ordovician seawater. In the Arbuckle Anticline area, nonstratal dolomite is present as small irregular bodies that are related to Pennsylvanian faults and are associated with the margins of stratal Butterly dolomite. The nonstratal dolomite, medium to coarsely crystalline and brightly luminescent, is characterized by high {sup 87}Sr/{sup 86}Sr ratios values, and Fe and Mn concentrations, relative to all Arbuckle carbonates. Such compositions suggest that this type of dolomite probably originated from fluids that were derived from the adjacent basin(s) during late Paleozoic time.

Volcanological and geochemical studies of Cambrian rift-related igneous rocks in the Western Arbuckle Mountains, southern Oklahoma  

NASA Astrophysics Data System (ADS)

The Carlton Rhyolite Group formed within a major Cambrian rift in southern Oklahoma. The rhyolites are exposed in the Wichita Mountains of southwestern Oklahoma and in the East and West Timbered Hills in the Arbuckle Mountains. My project is the first modern study of the Arbuckle rhyolites. Two thick rhyolite flows are present in the East Timbered Hills and are separated by a lacustrine volcaniclastic sequence. The nearest basement well shows a similar series of rhyolite lavas, but correlation between units in the two areas is not possible. Studies of an igneous breccia in the West Timbered Hills show it to represent a basaltic phreatomagmatic vent complex. The Arbuckle rhyolites have similar A-type geochemical compositions to those in the Wichitas and are divided into four distinct trace element groups. Late diabases in the Arbuckles show geochemical affinities to within-plate tholeiitic to alkaline basalts, similar to those documented in the Wichitas.

Deep-to-shallow carbonate ramp transition in Viola Limestone (Ordovician), southwest Arbuckle Mountains, Oklahoma  

SciTech Connect

The Viola Limestone (Middle and Upper Ordovician) of the southwest Arbuckle Mountains was deposited on a carbonate ramp within the southern Oklahoma Aulacogen. Depositional environments include (1) anaerobic, deep-ramp setting represented by microfacies RL, CH, CGL, and A, (2) dysaerobic, mid-ramp setting represented by microfacies B, and (3) aerobic, shallow-ramp setting represented by microfacies C and D. Deposition in the deep- and mid-ramp environments was dominated by bottom-hugging currents produced by off-platform flow of denser waters. Primary sedimentary structures include millimeter-size laminations, starved ripples, and concave-up and inclined erosional surfaces. Shelly benthic fauna are rare in A and B; trace fossils are common only in B. Deposits associated with the line-source gully, microfacies RL, CH, and CGL, are laterally confined; they have been observed only in the southwest Arbuckle Mountains. Primary sedimentary structures present in RL include wavy and ripple-cross laminae. Microfacies CH, contained within RL and interpreted as a submarine channel deposit, is present only at one locality. Primary sedimentary structures present in CH include an erosional base and several internal erosional surfaces, lateral accretionary sets, and imbricated, locally derived intraclasts. High total organic carbon (TOC) values have been reported for the lower Viola. TOC values of 1% have been reported from microfacies A, and TOC values of 5% have been reported from microfacies RL. These high values suggest that A and RL may act as hydrocarbon source rocks. Recognition of these microfacies in the subsurface will contribute to our knowledge of the Viola Limestone as an exploration target.

Petrology and geochemistry of the Buckhorn Asphalt (Desmoinsian) Arbuckle Mountains, Oklahoma  

SciTech Connect

The Buckhorn Asphalt is the informal name for asphalt-impregnated carbonate sediments of the Deese Group (Desmoinsian) deposited in the Mill Creek graben, Arbuckle Mountains, Oklahoma. This interbedded sequence of calcareous shale, carbonate sediments, and muddy chert conglomerates were deposited as inner marine shelf and fan delta facies in a sheltered coastal bay setting. Active faulting, due to the transpressional stress of continental collision, deformed the sediments and allowed secondary migration of Oil Creek Formation oil into the upper Deese section during or immediately following deposition. The non-asphaltic lower Deese carbonates have all the petrographic and geochemical characteristics of normal carbonate diagenesis by meteoric and/or subsurface groundwater. Asphaltic Deese carbonates contain unaltered aragonitic molluscs, neomorphosed skeletal aragonite and magnesian calcites, and delta TC-depleted sparry cements; this indicates that the presence of the oil and its alteration to asphalt physically limited and chemical influenced carbonate diagenesis. Deese asphalt has all the physical and chemical characteristics of oil degraded under low-temperature aerobic conditions by both biologic and inorganic processes. Comparison of the biomarker chemistry and organic TC composition of Deese asphalt with that of Oil Creek tar suggests that a substantial proportion of the Deese asphalt is composed of immature hydrocarbons. The chemical similarity of the indigenous Deese sedimentary hydrocarbons with this hypothetical immature hydrocarbon end member suggests that is may have an intraformational source.

Simpson-Arbuckle contact revisited in Northwest Oklahoma County, Oklahoma  

SciTech Connect

The Joins Formation, the lowermost formation of the Simpson Group, is traditionally the least studied or understood of the Simpson formations. The Joins, not known to produce hydrocarbons in central Oklahoma, is frequently overlooked by those more interested in the productive Simpson formations above and the Arbuckle carbonates below. In a study of the lower Simpson to upper Arbuckle interval in northwestern Oklahoma County, Oklahoma, the Joins Formation was found to be present. The central Oklahoma section consists of interbedded gray, olive gray and green splintery moderately waxy shale, cream to light gray homogeneous microcrystallin dolomite, and microcrystalline to fine crystalline fossiliferous slightly glauconitic well cemented sandstones are also noted. The entire Joins Formation is moderately to very fossiliferous; primarily consisting of crinoids, ostracods, brachiopods, and trilobites. The ostracod fauna closely resembles and correlates with the Arbuckle Mountain section, which has been extensively studied over the years by such authors as Taff, Ulrich and Harris. Beneath the Joins in this area is a normal section of Arbuckle dolomites. Due to the absence of a basal sand in the Joins the separation of the Joins and Arbuckle, utilizing electric logs only, is frequently tenuous. In comparison with the Arbuckle, the Joins tends to have higher gamma ray and S.P. values. Other tools, such as resistivity, bulk density and photoelectric (PE), are frequently inconclusive. For geologists studying the Simpson-Arbuckle contact in central Oklahoma, the presence or absence of the Joins Formation is best determined through conventional lithologic and palenontologic sample identification techniques. Once this has been done, correlation of electric logs with this type log is possible for the local area.

Paleomagnetic dating of diagenesis by basinal and meteoric fluids, Ordovician carbonates, Arbuckle Mountains, southern Oklahoma  

SciTech Connect

Late Paleozoic chemical magnetizations can be directly related to migration of basinal fluids and exposure to meteoric fluids in Ordovician carbonates in the Arbuckle Mountains. The Viola Formation contains a pervasive synfolding (Pennsylvanian) magnetization residing in magnetite, but, around some mineralized fractures and veins, there are alteration halos that contain a Late Permian chemical magnetization residing in hematite. The veins contain calcites and associated MVT minerals that formed from fluids which were radiogenic, relatively warm, and saline. These fluids caused the alteration and acquisition of the chemical magnetization. The origin of the synfolding magnetization is not well constrained and preliminary studies suggest it is not related to basinal fluids. Hematite Liesegang bands around calcite-filled fractures in dolomitic beds in the Kindblade Formation contain an apparent Early Permian chemical magnetization whereas unbanded rock contains a weak and unstable magnetization. Fluids, probably basinal in origin, which emanated from the fractures, caused the hematite banding and acquisition of the chemical magnetization. In contrast, field relations and geochemical studies indicate that the Royer Dolomite and clasts of the Royer in the Pennsylvanian Collings Ranch Conglomerate contain a Permian magnetization which was acquired as a result of exposure to meteoric fluids. Although all the chemical magnetizations in these carbonates are related to orogeny, they were cause by different fluids at apparently different times at several locations in the Arbuckle Mountains.

Fracture density and spacing along Washita Valley fault, Arbuckle Mountains, Oklahoma  

SciTech Connect

The authors document fracture density and spacing associated with the Washita Valley fault, a major strike-slip fault. The Washita Valley fault strikes northwest-southeast with up to 80 mi of exposure in southern Oklahoma and may be an early bounding fault of the Southern Oklahoma aulacogen (Ardmore/Marietta basins). Horizontal displacement on the fault has been estimated to be up to 40 mi, with vertical displacement on the order of 10,000 ft. Samples collected from traverses across the Washita Valley fault have been analyzed. The traverses cross the fault at different stratigraphic levels from Proterozoic igneous basement, through the Cambrian-Ordovician Arbuckle Group, Ordovician Simpson and Viola Groups, to the Silurian-Devonian Hunton Group. Several types of fracture systems are documented that reflect mechanical stratigraphy, burial depth during deformation, and episodic movement on the fault. The fractures in the study area include open fracture systems, calcite-filled fractures, tension gashes, and fractures related to pressure solution. The samples were cut parallel to the strike of the fault, vertical-normal to the fault, and horizontal-normal to the fault. These cuts allow examination of the total fracture strain, characterization of the fractures, and statistical analysis of fracture density. From these data, fracture density is shown to decrease exponentially moving away from the primary fault zone. The increased understanding of fracture patterns and characteristics will assist future exploration and development programs involving carbonate reservoirs associated with strike-slip systems.

Arbuckle source for Atoka Formation Flysch, Ouachita Mountains Frontal Belt, Oklahoma  

SciTech Connect

The 10-mi wide Ouachita Mountains frontal belt consists of Morrowan-Atokan flysch exposed in steeply south-dipping imbricate thrust slices. Two spatially distinct groups of paleocurrents were recognized during detailed mapping of 120 mi/sup 2/ in the frontal belt (between 95/sup 0/15'W and 95/sup 0/30'W). The east-west-trending Morrowan shallow-water shelf margin (now allochthonous) marks the boundary between these two domains. Westerly azimuths (259/sup 0/n = 213), typical of almost the entire Ouachita flysch sequence, are from the Atoka Formation south of the shelf margin. Easterly azimuths (66/sup 0/n = 75), previously unrecognized in the Ouachitas, are from the Atoka Formation where it overlies Wapanucka Limestone north of the margin. A third group of paleocurrents (193/sup 0/n = 21) are from the Johns Valley Shale (an olisto-strome that is the basinward equivalent of the Wapanucka Limestone). Easterly paleocurrent azimuths indicate a western source for the Atoka Formation north of the Morrowan shelf margin. Sediment from the Arbuckle uplift was apparently channeled northeastward down a trough that was isolated from the Ouachita basin to the south where sediment had an Appalachian provenance. The authors suggest that a trough was formed by listric fault blocks (tilted toward the continent) of the foundered Morrowan shelf margin. The bounding faults would be the southernmost of a series of northward younging south-side-down growth faults that have been recognized in the subsurface of the Arkoma basin to the north.

Southeast Hoover field: model of foreland tectonics of Arbuckle region, southern Oklahoma  

SciTech Connect

The Southwest Hoover field, located on the northern side of the Arbuckel Mountains, typifies the structural style common to the foreland of southern Oklahoma. This oil field, which produces primarily from the upper Arbuckle Group carbonates, was created in response to the Late Pennsylvanian Arbuckle orogeny. Various interpretations of the mode of deformation have been proposed such as wrench faulting, gravity sliding, and overthrusting. This research supports the idea of moderately dipping thrust faults created by northeast-southwest compression. Paleozoic rocks, originally deposited on the northern edge of the Southern Oklahoma aulacogen, have been transported to the northeast on southwest-dipping thrust faults, and now comprise the leading edge of the Arbuckle Mountains. In a detailed study, the Southeast Hoover field was reinterpreted in light of the compressional thrust-fault theory. Large-scale structural closure controls the location of hydrocarbon accumulation in the Arbuckle Group. Structures in the shallower horizons are characterized by detached anticlines that were created as a response to volume adjustments in adjacent upward-tightening synclines. Fault cutoff lengths and hanging-wall cutoff angles provide clues to predeformation fault-plane geometry. Comparison of the Southeast Hoover field with other structures in the Arbuckle region indicates a close similarity of style, which suggests this study can be used as a geologic model for interpreting foreland oil fields throughout southern Oklahoma.

The Oil Creek Formation (Whiterockian) is the second oldest of the five formations which make up the Simpson Group. Although widespread in the subsurface, it is exposed only in the study area and possibly in West Texas. The formation was deposited in a linear basin known as the Southern Oklahoma Aulacogen during a phase of apparent episodic subsidence. Deposition occurred in supratidal to shallow marine environments which were subjected to occasional tropical storms. Six depositional facies within the shaly upper member of the formation, previously known as the Oil Creek shale are defined. These facies are based on the lithology and fossil content of the quartzarenite and limestone beds because the alternating shale beds are monotonous and essentially lack skeletal fossils. This facies tract shows that, as in other formations of the Simpson Group, deposition apparently took place in one major cycle of transgression and regression. The transgressive phase of deposition is represented by the vertical sequence consisting of the Basal Sandstone Unit, Upper Offshore Facies, Transition Zone 1, and Lower Offshore Facies. The regressive phase includes Transition Zone 2, the Shoal Facies, Lagoon Facies, and Tidal Flat Facies. The Shoal Facies has relatively thick limestone beds composed of skeletal debris, quartz sand, and goethitic ooids, while the Lagoon Facies is dominated by terrigenous shale. The species composition and number in the different communities seem to have been largely determined by the nature of the substrate.

SciTech Connect

Outcrop and/or subsurface core studies of Butterly Dolomite, Cool Creek, Kindblade, and West Spring Creek formations reveal most of the Arbuckle Group to have been deposited as a series of storm-dominated, shallowing-upward sequences. They were deposited upon an extremely broad, nearly flat carbonate ramp that formed the southern margin of the North American craton (Knox, Arbuckle, Ellenburger, and El Paso groups) in the Upper Cambrian and Lower Ordovician. Shallowing-upward sequences were deposited in a cyclic manner, with individual fifth-order cycles only a few feet to tens of feet thick. These cycles record abrupt transgressions, caused by quick sea level rise, followed by progradation of a paleoshoreline as sea level gradually fell. Each cycle is divided into subtidal and tidal-flat components. Subtidal and tidal-flat components can be of equal thickness or can be skewed with one component becoming dominant and the other subordinate. Only half of all cycles are complete shallowing-upward sequences. Once understood the vertical stacking of facies in a cycle is predictable so that complete vs. incomplete cycles can be easily recognized. These distinctions are very important to recognize because well-developed subtidal portions of a cycle can form reservoir intervals when dolomitized.

The Arbuckle Group of southern Oklahoma displays the only complete exposure of the shallow-water carbonates that characterize the Lower Ordovician of interior North America. Trilobites have been described from some parts of this sequence and sporadic occurrences of other invertebrates are known, but much of the sequence is sparingly fossiliferous. As a consequence, these magnificent exposures have not contributed notably to continuing efforts toward development of a comprehensive biostratigraphic scheme for the Lower Ordovician of the North American platform. Samples collected at 25-ft intervals through the Arbuckle Group along and adjacent to Interstate Highway 35 on the south flank of the Arbuckle anticline near Ardmore, Oklahoma, produced conodonts in abundances ranging from a few tens to over a thousand elements per kilogram and displaying good to excellent preservation with low CAI. These conodonts document a biostratigraphic continuum that provides a standard for correlation of Lower Ordovician rocks in the subsurface of central US and of the many localized and incomplete outcrops of generally equivalent strata in the Ozark and Upper Mississippi Valley regions. The stratigraphic continuity of the collections makes the I-35 section an ideal standard reference section for graphic correlation of Lower Ordovician rocks containing conodonts of the Mid-Continent Province.

Three-dimensional geologic model of the Arbuckle-Simpson aquifer, south-central Oklahoma  

USGS Publications Warehouse

The Arbuckle-Simpson aquifer of south-central Oklahoma encompasses more than 850 square kilometers and is the principal water resource for south-central Oklahoma. Rock units comprising the aquifer are characterized by limestone, dolomite, and sandstones assigned to two lower Paleozoic units: the Arbuckle and Simpson Groups. Also considered to be part of the aquifer is the underlying Cambrian-age Timbered Hills Group that contains limestone and sandstone. The highly faulted and fractured nature of the Arbuckle-Simpson units and the variable thickness (600 to 2,750 meters) increases the complexity in determining the subsurface geologic framework of this aquifer. A three-dimensional EarthVision (Trademark) geologic framework model was constructed to quantify the geometric relationships of the rock units of the Arbuckle-Simpson aquifer in the Hunton anticline area. This 3-D EarthVision (Trademark) geologic framework model incorporates 54 faults and four modeled units: basement, Arbuckle-Timbered Hills Group, Simpson Group, and post-Simpson. Primary data used to define the model's 54 faults and four modeled surfaces were obtained from geophysical logs, cores, and cuttings from 126 water and petroleum wells. The 3-D framework model both depicts the volumetric extent of the aquifer and provides the stratigraphic layer thickness and elevation data used to construct a MODFLOW version 2000 regional groundwater-flow model.

Storm deposits (tempestites) in Ordovician cratonic carbonates (Arbuckle Group, south-central Oklahoma)  

SciTech Connect

The Early Ordovician Kindblade Formation (Arbuckle Group), exposed in the Arbuckle Mountains of south-central Oklahoma, is a shallow marine epicontinental carbonate sequence that contains numerous storm deposits. The storm deposits (tempestites) are of two types, proximal and distal; the latter dominates in terms of both number and aggregate thickness. Distal tempestites consist of a fining upward sequence, 5 to 50 cm (2 to 20 in.) thick, that overlies an eroded hardground or firmground. The sequence consists of a lag lithoclastic grainstone that grades up into a laminated peloidal grainstone and then into mudstone. Primary sedimentary features such as laminations, burrows, and allochems are truncated at the surfaces, and borings are filled with unsorted lithoclasts. The lithoclasts at the base of the sequence are bored, generally well rounded, discoid in shape, and consist of mudstone, peloidal packstone, and oolitic grainstone. The overlying mudstone is sparsely fossiliferous and bioturbated with burrows either selectively dolomitized or infilled with lithoclastric grainstone. Proximal tempestites consist of coarse lithoclastic flat pebble conglomerate beds approximately 1 m (3.25 ft) thick that are interbedded with ooid grainstone and overlie mudstone. The contact between the units is sharp and erosional. The lithoclasts are of variable composition and may be up to 20 cm (7.75 in.) in diameter. The two types of tempestites occur in crude cycles, which consist of distal deposits overlain by proximal tempestites and ooid grainstones. The abundance of the storm deposits in the section, approximately one every 20 cm (7.75 in.), indicates that hundreds of storm-induced events are recorded in the Kindblade Formation.

Structural styles: Arkoma and Ardmore basins and Arbuckle Mountains  

SciTech Connect

In the Ouachita thrust belt, thin-skinned deformation has telescoped the sedimentary section along major thrust systems. In the frontal Ouachitas, Ti Valley thrust places Ordovician and Devonian rocks over Pennsylvanian rocks. Exploration for hydrocarbons on this and older thrust sheets relies on fractured Bigfork Chert and Arkansas Novaulite for reservoirs. Imbricate thrusting associated with the Choctaw thrust has produced hydrocarbon traps in the allochthonous Spiro Formation, as at Wilburton field. Thin-skinned Ouachita thrusting was superimposed over normal faults associated with early rifting, which probably localized the position of many Pennsylvanian faults. Due to northward-advancing thrust sheets, faults were reactivated by tectonic and sedimentary loading of the previously weakened foreland crust. Some of these faults may also have been reactivated as high-angle reverse faults by Ouachita compression. The discovery of commercial volumes of gas in the Pennsylvanian Spiro and Ordovician Arbuckle Group in these autochthonous subthrust fault blocks has initiated a major drilling program. Basement-involved compressional structures occur in the Ardmore basin-Arbuckle Mountains area southwest of the Ouachita thrust belt. Controversy surrounds interpretation of major faults as wrench type, with various amounts of strike-slip, or as reverse dip-slip, with large amounts of shortening. Hydrocarbons are trapped in a variety of individual structures, and include (1) large doubly-plunging anticlines exposed at the surface, (2) deep-basin structures having no surface expression, (3) large anticlines developed under, or immediately in front of, mountain overhangs, (4) faulted anticlines that subcrop the Pennsylvanian sediments on the hanging walls of buried mountain fronts, and (5) overturned beds in the footwall of major reverse faults.

Paleomagnetic dating of dedolomitization in Cambrian-Ordovician Arbuckle Group limestones and Pennsylvanian Collings Ranch Conglomerate, southern Oklahoma  

SciTech Connect

Paleomagnetic and petrographic techniques have been used to date dedolomitization in stratigraphic and tectonic dolomites exposed in the Arbuckle Mountains, southern Oklahoma. The authors examined red dedolomites and their dolomite precursors from the Cambrian-Ordovician Arbuckle Group and dolomite clasts in the Pennsylvanian Collings Ranch Conglomerate. Authigenic hematite is associated with the dedolomite and precipitated as a result of the dedolomitization process. Dedolomite is associated with paleokarst and fractures, burrows, Liesegang bands, and red rims on conglomerate clasts. Magnetic directions from these dedolomitized rocks range from Dec = 145/sup 0/ to 154/sup 0/ and Inc = 2/sup 0/ to 9/sup 0/, with ks greater than 50 and /alpha/95s less than 5. The directions are constrained by fold tests to be post-structural (Late Pennsylvanian to Early Permian) and in the Collings Ranch to post-depositional. These directions correspond to a reversed Pennsylvanian pole position and the magnetizations are interpreted as chemical remanent magnetizations (CRM) acquired when hematite precipitated during dedolomitization.

Paleokarstic phenomena of the Lower Ordovician red bed sequences of the Arbuckle group, southern Oklahoma  

SciTech Connect

Oil and gas production has been reported recently from paleokarstic Arbuckle reservoirs in the Ardmore and Arkoma basin. The West Spring Creek and the Kindblade formations apparently exhibit karstic features. The most extensive surface exposure of these formations is on the southern flank of the Arbuckle anticline along Interstate 35 north of Ardmore, Oklahoma. The lithology is predominantly limestone, ranging from argillaceous mudstone to oolitic and/or bioclastic grainstones. However, minor amounts of sandstone were also observed.These lithologies are characteristic of various peritidal facies. Of particular interest in this outcrop are three distinct red bed zones. Although the zones are part of the repetitive shallowing-upward cycles that characterize the West Spring Creek Formation, ample evidence suggests the red beds represent subaerial exposure surfaces where karstification took place. Many of the thin bedded, rubbly mudstones and wackestones actually represent varieties of breccia commonly associated with karst. Collapse and crackle breccia are most commonly observed. Small solution channels and other vugs are usually completely occluded by calcite cement. However, solution cavities or vugs with diameters larger than 10 cm (3.9 in.) are lined with drusy calcite. Hematite-impregnated sediment occurs as thinly laminated infilling of solution vugs and cavities and also acts as a cementing agent of collapse breccias. Preliminary evidence suggests that karstification processes were active during Arbuckle deposition.

Evidence for existence of Sabkhalike conditions in Upper Arbuckle Group, Slick Hills, southwestern Oklahoma  

SciTech Connect

In the Slick Hills of southwestern Oklahoma, the Ordovician upper Arbuckle Group carries a cryptic record of evaporite precipitation. This record is particularly well developed in the Cool Creek and, to a lesser extent, the West Spring Creek formations. Principal lines of evidence supporting this conclusion are (1) salt pseudomorphs (after gypsum( )) preserved in chert and, less commonly, in limestone (principal pseudomorphing minetals are calcite and dolomite), (2) molds of salts in cherts, (3) traces of anhydrite and celestite within chert nodules, (4) collapse breccias the authors interpret as resulting from the solution of sulfate deposits, (5) dolomite beds that have appropriate isotope values, and (6) length-slow and other varieties of chert indicative of waters of high ionic strength, some of which are the distinctive cauliflower variety. In addition, a number of features suggest that waters of unusual composition (ie., modified seawater) were present on the Arbuckle platform from time to time. These features include rare bedded (primary( )) cherts, subaqueous shrinkage cracks, and ooids of unusual and variable textures. Their conclusion is that during upper Arbuckle Group deposition, particularly Cool Creek deposition, the vast Arbuckle platform was periodically exposed and a sabkhalike environment developed in which dolomitization and gypsum/anhydrite precipitation took place. Subsequent reestablishment of fully marine conditions resulted in the early removal of the sulfates, leaving only a cryptic evaporite signature. Our interpretation can be supported in a general sense by the fact that (1) the fauna of the Cool Creek Formation is impoverished by comparison with adjacent formations, (2) the area was in a suitable climatic zone, and (3) the widespread occurrence of detrital quartz in the Cool Creek is compatible with exposure of the platform and consequent movement of clastics into the area.

The geological significance of the boundary between the Fort Sill and Signal Mountain Formations in the lower Arbuckle Group (Cambrian)  

SciTech Connect

During the upper Cambrian, a transgression inundated the Southern Oklahoma aulacogen enveloping a landscape that consisted of hills of Cambrian-aged rhyolite up to 350 m in height. Initial deposits on this topography--the Reagan Formation--consist of siliciclastics that were deposited as alluvium and succeeding tidally-influenced marine sandstones and shales. The siliciclastics grains are made up of local rhyolite, quartz and authigenic glauconite. The overlying Honeycreek Formation is defined by the addition of carbonated detritus in the form of tidally-influenced pelmatozoan grainstones. The passage from the Honeycreek to the overlying Fort Sill Formation of the Arbuckle Group is marked by the incoming of beds of lime mudstone and the gradual disappearance of grainstones and siliciclastics. The contact between the Fort Sill and the overlying thinly-bedded dark grey bioclastic limestones of the Signal Mountain Formation is one of the most distinctive horizons in the Arbuckle Group. The contact evidently marks a substantial change in depositional environment. In detail the contact is sharp and shows evidence of minor erosion, although no karsting has been detected. The authors suggest that the contact surface records a regression, perhaps associated with dolomitization and followed by some erosion. A regression is also indicated by the local occurrence of a laminated tidal flat unit with traces of evaporites that outcrops in the far west of the Slick Hills immediately below the formation contact. They suggest that the Signal Mountains as a transgressive unit, incorporating siliciclastics transported into the area during the regression. It has been suggested that the unconformity reflects localized tectonism associated with the evolution of the Southern Oklahoma aulacogen. On the other hand the surface may correlate with a craton--wide Sauxian' hiatus.

Effects of municipal ground-water withdrawals on the Arbuckle-Simpson Aquifer, Pontotoc County, Oklahoma  

USGS Publications Warehouse

The Arbuckle-Simpson aquifer in south-central Oklahoma consists of a thick sequence of folded and faulted carbonate and clastic rocks of Upper Cambrian to Middle Ordovician age. Fractures and karst features locally increase the aquifer's capacity to transmit and store ground water. The aquifer is a principal source of water for municipal and rural users. A hydrologic study was conducted to evaluate the effects of municipal ground-water withdrawal from the Arbuckle-Simpson aquifer on local ground-water levels and discharge from nearby springs and streams in south-central Pontotoc County. A municipal well was pumped for 63 hours at an average rate of 1,170 gallons per minute. A maximum observed drawdown of 0.3 feet was recorded half a mile from the pumping well. Drawdown was observed as far as 1.2 miles from the pumping well. No measurable response was observed at any of the surface-water-discharge measurement sites; however, recharge from precipitation may have masked any decreases in discharge caused by the pumping. Simultaneous pumping of two municipal wells for 241 hours at average rates of 1,170 and 2,730 gallons per minute resulted in a maximum observed drawdown of 1.3 feet recorded at an average distance of 0.80 miles from the pumping wells. The most distant drawdown observed was at an average distance 1.1 miles from the pumped wells. Less that 2 days after pumping stopped, increases in springflow were recorded at two springs; it is unknown whether these discharge responses reflect the effects of recharge from precipitation, or the combined effects of precipitation and the cessation of ground-water withdrawal. The effects of the stress tests on the hydrologic system were offset by recharge from concurrent precipitation. The maximum observed drawdown represents about 6 percent of the median natural water-level fluctuation during the study period. The effect of drawdown could become critical during extended periods of low precipitation, if water levels are already near the bottom of domestic wells in the area. However, a comparison of maximum observed drawdown (1.3 ft) with the minimum saturated thickness of fresh ground water (1,500 ft) suggests that municipal pumping had little effect on the amount of ground water stored in the Arbuckle-Simpson aquifer in the study area. This evaluation is based on the limited pumping rates and times of the stress tests.

Bedded cherts in the Early Ordovician Arbuckle Group of southwestern Oklahoma  

SciTech Connect

Bedded cherts are a rarely occurring but environmentally significant facies in the Early Ordovician Arbuckle Group. Two such units have been identified: one in the Cool Creek Formation and one in the Kindblade Formation. In each, microcrystalline calcite and dolomite alternate in thin laminae with microcrystalline silica in units up to 25 cm in thickness. The areal extent of the bedded cherts encompasses more than 130 km{sup 2}. It is hypothesized that the interlaminated cherts and micrites were deposited in very shallow marine conditions. A relatively small part of the Oklahoma Aulacogen was cut off from open ocean circulation, resulting in an isolated lagoon. The chert/micrite couplets may represent seasonal deposits in the lagoon. During seasonal flooding, slightly deeper water resulted in algal growth with accompanying precipitation of carbonates and solution of detrital quartz sand. During the dry season, the dissolved silica precipitated, resulting in thin layers of microcrystalline chart. Some carbonate layers contain small pseudomorphs after what may have been gypsum and anhydrite crystals and nodules, indicating that salinities increased enough to permit formation of evaporites. At least ten couplets occur in the thickest units, suggesting that the lagoon existed for ten wet-dry seasons.

Cottonwood Creek-Hewitt trend Arbuckle play (southern Oklahoma): example of complexly faulted and fractured karst trap  

SciTech Connect

The Hewitt field (T4, 5S, R1, 2W), located along the northwest-southeast-trending Wichita-Criner Hills anticlinorium, is the ninth largest field in Oklahoma with ultimate recovery projected to exceed 250 million bbl. The development of the anticlinorium was initiated by the Wichita orogeny during the Morrowan, forming north-south-trending folds. During the Atokan, extensive erosional forces removed thick sequences and exposed the Ordovician Arbuckle Group. The uplift was subsequently covered by Deese and Hoxbar clastic sediments during the Middle Pennsylvanian. The Late Pennsylvanian Arbuckle orogeny produced compressional stress from the southwest and resulted in refolding of the uplift features and movement along high-angle faults. The recent discovery of prolific hydrocarbon reserves in Ordovician carbonates (Canadian, Arbuckle Group) has renewed interest along this prolific trend. The productive reservoir in the Hewitt-Cottonwood Creek area is the dolomitic Brown zone (Kindblade Formation), located approximately 1000 ft below the top of the Arbuckle group. The zone consists of crystalline dolomite, 500-600 ft thick, with adequate porosity and permeability developed to form significant reservoirs due to karstification of the extensive fracture systems. The Bray zone (West Spring Creek Formation-upper Arbuckle Group) has production in the Healdton and southwestern Lone Grove fields from fractured, arenaceous, finely granular dolomite and may be an additional possible reservoir. The combination of good untested reservoirs located on structural features associated with block faulting, as illustrated by seismic sections across the Criner fault, gives an excellent indication that the trend may have great future potential within a mature province.

Three-Dimensional EarthVision Modeling for Ground-Water Resource Applications: Arbuckle-Simpson Aquifer, Southern Oklahoma  

NASA Astrophysics Data System (ADS)

The Arbuckle-Simpson aquifer in southern Oklahoma encompasses more than 500 square miles and is the primary source of water in the area. The subsurface hydrogeologic framework of this structurally complex carbonate aquifer was unresolved until now because of the complex geology of the aquifer's confining rock units with stratigraphic unit thicknesses from 60 to 1200 m and fault displacements over 2000 m. Three- dimensional analyses of geologic surface and subsurface data have led to the construction of a 3-D EarthVision (EV) geologic framework model that characterizes the lateral continuity of water-bearing rock units across fault zones. The geologic modeling was planned in collaboration with ongoing USGS MODFLOW modeling efforts supported by the Oklahoma State-funded Arbuckle-Simpson Hydrology Study. Although traditional ground-water reservoir characterization techniques were used in the construction of the 3-D EV model, which included the integration of outcrop geology and stratigraphic elevations from more than 300 water and petroleum wells, new geophysical data were also integrated into the model. Despite limited funding for acquisition of basin-wide subsurface data, such as 3-D seismic or deep-hole control wells and cores, new methods of compiling and assimilating multiple data sources into a workable database are demonstrated in this study. The Arbuckle-Simpson 3-D EV model depicts more than 50 principal and intermediate faults and stratigraphic tops (td's) for the following units: Precambrian basement, Arbuckle Group, Simpson Group (Bromide Formation), and overlying units (undivided). To support the subsurface data, existing seismic and gravity data and recently acquired electromagnetic survey data were incorporated into the stratigraphic elevation datasets. Electromagnetic data acquired from a helicopter geophysical survey was used to identify shallow faults that have no recognizable surface expression. Electrical resistivity imaging was conducted across some major fault zones to help accurately locate the fault traces and determine the degree of dip in the subsurface. Gravity surveys were conducted to identify subsurface faults and the depth to Precambrian basement, both of which helped to constrain the volumetric extent of the water-bearing rock units. The resulting framework model represents the first depiction of the volumetric and lateral extent of the aquifer. The faulted geologic layers have also been discretized using a domain with 200x200 meter-node spacing and successfully integrated into the Arbuckle-Simpson Hydrology Study's multi-layer MODFLOW ground-water model.

Karst-related diagenesis and reservoir development in the Arbuckle Group, Wilburton field, Oklahoma  

SciTech Connect

Wilburton field is a multizone reservoir on the southwestern edge of the Arkoma basin. The most recent zone to be declared commercial is the Cambrian-Ordovician Arbuckle Group. Faults, structural position, depositional environment, and diagenetic alterations play a role in controlling reservoir quality, communication of fluids and pressures within the reservoir, and stratigraphic correlations. The Arbuckle Group in Wilburton field consists of dolomite, calcareous dolomite and minor clastic-rich intervals, chert, and dolomitic limestones. Early diagenesis consisted of pervasive dolomitization that created a dolomudstone with low (12%) intercrystalline porosity. The regionally extensive Middle Ordovician unconformity, which occurs at the top of the Arbuckle Group, exposed that carbonate surface to meteoric conditions that resulted in formation of karst. The porosity development or enhancement associated with karsting modified depositional textures and their related pore geometries. Stratigraphically, the Arbuckle section can be divided into two zones. An upper zone, 200-250 ft thick, is characterized by a lack of fracturing and brecciation, and by fluid flow mainly through the matrix or intercrystalline pore system. Porosity development in these intervals extends across the field. The lower zone is characterized by multiple intervals of fracturing, brecciation (all three types), and solution collapse. The Arbuckle is most likely productive where solution has enhanced intercrystalline, fracture, and breccia porosity, and burial cements have failed to completely fill pore space. The authors anticipate that porosity development in Arbuckle carbonates in other areas is similarly controlled and should be productive.

Paleomagnetism of the Cambro-Ordovician Arbuckle Group and associated deposits in the southern Oklahoma Aulacogen: Evidence for block rotations  

NASA Astrophysics Data System (ADS)

The magnetization in hydrocarbon-impregnated Arbuckle Group limestones from the southern margin of the Southern Oklahoma Aulacogen (Limestone Hills) is secondary and resides in magnetite. The magnetization (Declination/Inclination=128°/2°, ?95=7.6°, k=79) fails a fold test and is post Pennsylvanian. The corresponding pole position (146°E, 30°N), however, does not coincide with the post-Pennsylvanian Apparent Polar Wander Path (APWP). Some Permian speleothems that fill caves in these rocks contain magnetizations that are also anomalous. Shallow remanent inclinations from the folded limestones and speleothems suggest that the most likely time of remanence acquisition was the Permian. The directions are at least 30° in declination from the expected directions based on the inferred ages of the magnetizations. This discrepancy can be explained by a horizontal counterclockwise rotation, consistent with left-lateral wrench faulting, during deformation of the aulacogen.

Geophysical Investigation of the Arbuckle-Simpson Aquifer, Oklahoma, to Determine the Influence of Subsurface Structure on Groundwater Flow  

NASA Astrophysics Data System (ADS)

We investigate an area of the Arbuckle-Simpson aquifer in southern Oklahoma by employing near-surface geophysical surveying. This predominantly carbonate aquifer encompasses the Simpson, Arbuckle, and Timbered Hills Groups, which range in age from Upper Cambrian to Middle Ordovician. The aquifer serves as a principle water source for the surrounding area and feeds several major springs and creeks, including Pennington Creek, around which a number of rare species dwell. Due to the high amount of fracturing and faulting present in the aquifer system, the possible effects of large-scale groundwater withdrawal are poorly understood and have spurred increased interest in a comprehensive investigation of the aquifer. We seek to understand the subsurface structure of a small area of the aquifer, focused around Pilot Springs, by identifying and interpreting faults and their interaction with the groundwater hydrology. To this end, we have carried out electrical resistivity soundings using Wenner and Schlumberger array spreads. Analysis of these data is being performed to identify faults and estimate depths to the water table. Modeling of horizontal layers is carried out by means of the IPI2win Resistivity Sounding Interpretation algorithm from Moscow State University. This modeling approach allows us to obtain for each sounding point an optimized subsurface model that specifies the number of layers present and the apparent resistivity and depths to each layer. We are able to refine this model based on our prior understanding of the geology of the region. At least one sounding appears to reveal the presence of one of the major north bounding faults in the area. Further surveying is planned, including additional resistivity soundings as well as resistivity profiling and ground-penetrating radar.

Cores from various localities in south-central and north-central Oklahoma display surprisingly similar suites of karstic and diagenetic phenomena. Vadose dissolution tubes, solution-enlarged fractures, collapse breccias, and vugular porosity, where present are considered evidence of karstification. Primary speleothemic precipitates were not readily observed; either they were not present or were obscured by later hydrothermal dolomitization. A complex history of exposure and subsidence is recorded in these rocks. Immature karst profiles may have subsided at rapid rates under conditions that prevented low-temperature phreatic cementation, thus preserving the open pore network of the karst profile. Deep burial diagenesis is evidenced by the appearance of highly ferroan baroque dolomite cement partially or entirely occluding vugular and fracture porosity. In addition, host-rock carbonates were extensively replaced by typical thermal xenomorphic dolomite. Cathodoluminescent microscopy indicates that the hydrothermal dolomite is uniform in composition and was precipitated under highly reducing conditions. Dolomite cementation was arrested when oil migrated into the remaining pore space. A complex multistage fracture network is present in cores from the Healdton oil field. Early fracture systems are healed by highly ferroan, dull luminescent baroque dolomite, and later fractures are cemented with nonferroan, brightly luminescent cement.

Geochemistry of Cambro-Ordovician Arbuckle limestone, Oklahoma: Implications for diagenetic ?18O alteration and secular ?13C and 87Sr /86Sr variation  

NASA Astrophysics Data System (ADS)

Isotopic analyses of 227 limestone samples from the Cambro-Ordovician Arbuckle Group, Oklahoma, document slow secular changes in the chemistry of the limestones. From late Cambrian to early Ordovician, the ?18O values of the limestones increase from -10%. to -7%. (PDB); ?13C values decrease from 0%. to -2%. (PDB); and 87Sr /86Sr ratios decrease from 0.7091 to 0.7088. The light ?18O values suggest that all Arbuckle limestones underwent diagenetic alteration, probably caused by meteoric water recharged during the development of the overlying, pre-middle Ordovician unconformity. The gradual ?18O increase from late Cambrian to early Ordovician reflects reduced 18O depletion with decreasing burial temperature during alteration, although the presence of additional primary secular ?18O variation cannot be ruled out. The ?13C and 87Sr /86Sr variations, in accord with ?13C and 87Sr /86Sr variations in the literature, represent primary secular variations. The variations indicate that the ?13C value and 87Sr /86Sr ratio of early Paleozoic surface seawater decreased from late Cambrian to early Ordovician. The ?13C variation during this time period seems to correlate with sea-level variation. Specifically, during sea-level fall, an increase in the rate of oxidation of organic matter caused 13C depletion of inorganic bicarbonate in seawater. As a result, early Ordovician carbonates, probably deposited during the regression stage of the latest Precambrian to latest early Ordovician cycle, became 13C depleted, relative to late Cambrian carbonates. The decrease of seawater 87Sr /86Sr ratio from late Cambrian to early Ordovician may have resulted from decreased riverine Sr input caused by decreased rate of continental weathering.

Folding at two different scales of the Paradox anticline in the Ordovician Cool Creek Formation, Arbuckle Group, Slick Hills, southwestern Oklahoma: A paleomagnetic fold test study.  

NASA Astrophysics Data System (ADS)

The carbonates in the Cambro-Ordovician Arbuckle Group, part of the southern Oklahoma aulacogen, has been the subject of previous paleomagnetic studies with a focus primarily on their origin of the magnetizations. Most previous studies indicate late Paleozoic magnetizations that reside in hematite. However, Elmore et al. (1988) conducted a paleomagnetic study of the Arbuckle Group carbonates from the Slick Hills area utilizing six sites from a north-plunging tightly folded Paradox anticline. Alternating field and thermal demagnetization results from their study indicated a post-tilting remanence that resides primarily in magnetite. Also, based on the difference between the observed and expected remanence directions, they suggested a possible 30° block rotation. As a continuation of their work, this paleomagnetic study was conducted to corroborate the observed 30° rotations utilizing more sites from the Paradox anticline and the use of a more sensitive 2G Cryogenic magnetometer. In addition, the major focus of this paleomagnetic study is to examine the relationship between the timing of remanence acquisition with respect to the primary (F1) and the secondary (F2) folds of the Paradox anticline. To this extent, oriented samples of carbonates have been collected from the Ordovician Cool Creek Formation of the Paradox anticline from the Slick Hills area from both the F1 and the F2 folds. Low temperature demagnetization protocols have been carried out on these samples to remove the effects of multidomain magnetite grains thereby isolating better the characteristic remanence components. Post-low temperature cleaning, the thermal step-demagnetization procedure isolates primarily two components: 1.) a low-temperature steep downward viscous remanent magnetization; and, 2.) a high-temperature characteristic remanent magnetization component, residing primarily in magnetite, with shallow remanence directions scattered towards the east-south-east to south-east. Fold test results indicate a post-tilting remanence for the F1 major folding of the Paradox anticline similar to that observed by Elmore et al. (1988). However, an interesting new observation is the paleomagnetic fold test results from the F2 fold that indicates a syntilting remanent magnetization. In addition, the south-easterly scattered shallow remanence directions from these Ordovician Cool Creek carbonates substantiates a possible 30° rotation that is likely attributed to the left-lateral wrench faulting observed in this area.

Geochemical and isotopic constraints on the diagenetic history of a massive stratal, late Cambrian (Royer) dolomite, Lower Arbuckle Group, Slick Hills, SW Oklahoma, USA  

NASA Astrophysics Data System (ADS)

The diagenetic history of the late Cambrian massive Royer dolomite from the lower Arbuckle Group, Slick Hills, SW Oklahoma, USA, has been evaluated through comprehensive geochemical analyses. The dolomite probably formed during early diagenesis from contemporaneous late Cambrian seawater, evidenced by similar 87Sr /86Sr ratios (from 0.70891 to 0.70913) of most (70%) dolomite samples, to coeval late Cambrian seawater (from 0.7089 to 0.7092). Very light ?18O values (-10.2 to -12.9‰, PDB), however, indicate that the dolomite was significantly modified during burial. Correlation of various geochemical parameters (Sr, Fe, ?18O, and 87Sr /86Sr ) demonstrates that dolomite samples with increased modification are characterized by lower Sr and higher Fe concentrations, lighter ?18O values, and less radiogenic 87Sr /86Sr ratios. This correlation, coupled with the light ?18O values of the dolomite, demonstrates that meteoric water, recharged into overlying carbonates, was responsible for burial modification of the dolomite. Geochemical comparison of the dolomite with associated limestone and quantitative modelling of ?18O, Sr, and 87Sr /86Sr variation during water-rock interaction suggest that the dolomite underwent long-lasting modification. The timing of meteoric modification was coincident with the development of regional overlying unconformities corresponding to emergence of the carbonate platform. Similar diagenetic modification has probably been responsible for 18O depletion and trace element modification of ancient dolomites in many other areas, although many of these dolomites have been interpreted to have formed either in mixing-zone environments or in subsurface environments.

BLACK FORK MOUNTAIN ROADLESS AREA, ARAKANSAS AND OKLAHOMA.  

USGS Publications Warehouse

Black Fork Mountain Roadless Area covers about 21 sq mi in the Ouachita National Forest in Polk County, Arkansas and LeFlore County, Oklahoma. On the basis of a mineral survey the area has little promise for the occurrence of metallic mineral resources. Stone and sand and gravel suitable for construction purposes occur in the Jackfork Sandstone and the Stanley Shale which also occur outside the roadless area. Although the potential for gas and oil is unknown and no resource potential was identified, some investigators believe that there is a possibility for the occurrence of gas and oil in the roadless area.

Source of shallow Simpson Group Oil in Murray County, Oklahoma

Oils produced from the Simpson Group (Middle Ordovician) in three shallow fields located north of the Arbuckle Mountains in Murray County, Oklahoma, have widely differing compositions: SW Sandy Creek, 28.9{degree} API, 0.57% sulfur; Davis NE, 25.9{degree} API, 0.72% sulfur; Sulfur NW, 16.4{degree} API, 1.44% sulfur. From gas chromatography and biomarker analysis, they determined that the oils were derived from the same source and that the differences in composition are due to biodegradation of the oils in the shallow reservoirs. A comparison of the biomarker assemblage of the Simpson Group oils to several other oils produced in the Arbuckle Mountain area showed that the Simpson Group assemblage highly resembled the assemblage of a Woodford Formation oil (Devonian) but had no similarity to a Viola Formation oil (upper Middle Ordovician). The Simpson Group oils also differed markedly from an oil produced from the Arbuckle Group (Lower Ordovician) in the nearby, shallow Southeast Hoover field. Their data suggest that the source of the shallow Simpson Group oils is the Woodford Formation located in the downthrown Mill Creek syncline south and west of these fields. A large vertical migration along faults or within the fault block is implied by this geometry. However, the Arbuckle Group oil from the Southeast Hoover field, south of the syncline, has a different source.

Geochemistry of Cambro-Ordovician Arbuckle limestone, Oklahoma: Implications for diagenetic. delta. sup 18 O alteration and secular. delta. sup 13 C and sup 87 Sr/ sup 86 Sr variation  

SciTech Connect

Isotopic analyses of 227 limestone samples from the Cambro-Ordovician Arbuckle Group, Oklahoma, document slow secular changes in the chemistry of the limestones. From late Cambrian to early Ordovician, the {delta}{sup 18}O values of the limestones increase from {minus}10{per thousand} to {minus}7{per thousand} (PDB); {delta}{sup 13}C values decrease from 0{per thousand} to {minus}2{per thousand} (PDB); and {sup 87}Sr/{sup 86}Sr ratios decrease from 0.7091 to 0.7088. The light {delta}{sup 18}O values suggest that all Arbuckle limestones underwent diagenetic alteration, probably caused by meteoric water recharged during the development of the overlying, pre-middle Ordovician unconformity. The gradual {delta}{sup 18}O increase from late Cambrian to early Ordovician reflects reduced {sup 18}O depletion with decreasing burial temperature during alteration, although the presence of additional primary secular {delta}{sup 18}O variation cannot be ruled out. The {delta}{sup 13}C and {sup 87}Sr/{sup 86}Sr variations, in accord with {delta}{sup 13}C and {sup 87}Sr/{sup 86}Sr variations in the literature, represent primary secular variations. The variations indicate that the {delta}{sup 13}C value and {sup 87}Sr/{sup 86}Sr ratio of early Paleozoic surface seawater decreased from late Cambrian to early Ordovician. The {delta}{sup 13}C variation during this time period seems to correlate with sea-level variation. Specifically, during sea-level fall, an increase in the rate of oxidation of organic matter caused {sup 13}C depletion of inorganic bicarbonate in seawater. As a result, early Ordovician carbonates, probably deposited during the regression stage of the latest Precambrian to latest early Ordovician cycle, became {sup 13}C depleted, relative to late Cambrian carbonates. The decrease of seawater {sup 87}Sr/{sup 86}Sr ratio from late Cambrian to early Ordovician may have resulted from decreased riverine Sr input caused by decreased rate of continental weathering.

Heat flow in Oklahoma  

NASA Astrophysics Data System (ADS)

Twenty new heat flow values are incorporated, along with 40 previously published data, into a heat flow map of Oklahoma. The new heat flow data were estimated using previous temperature measurements in boreholes made by American Petroleum Institute researchers and 1,498 thermal conductivity measurements on drill cuttings. The mean of 20 average thermal gradients is 30.50sp°C/km. In general, thermal gradients increase from SW (14.11sp°C/km) to NE (42.24sp°C/km). The range of 1,498 in situ thermal conductivity measurements (after corrections for anisotropy, in situ temperature, and porosity) is 0.90-6.1 W/m-K; the average is 1.68 W/m-K. Estimated near-surface heat flow (±20%) at 20 new sites in Oklahoma varies between 22 ± 4 mW/msp2 and 86 ± 17 mW/msp2; the average is 50 mW/msp2. Twenty-seven new heat-generation estimates, along with 22 previously published data, are used to create a heat generation map of Oklahoma. The range of heat production estimates is 1.1-3.5 muW/msp3, with an average of 2.5 muW/msp3. The heat flow regime in Oklahoma is primarily conductive in nature, except for a zone in northeast. Transient effects due to sedimentary processes and metamorphic/igneous activity, as well as past climatic changes, do not significantly influence the thermal state of the Oklahoma crust. Heat flow near the margins of the Arkoma and Anadarko Basins may be depressed or elevated by 5-13 mW/msp2 by refraction of heat from sedimentary rocks of relatively low thermal conductivity (1-2 W/m-K) into crystalline basement rocks of relatively high thermal conductivity (˜3-4 W/m-K). The heat generation-heat flow relationship shows a modest correlation. The relatively high heat flow (˜70-80 mW/msp2) in part of northeastern Oklahoma suggests that the thermal regime there may be perturbed by regional groundwater flow originating in the fractured outcrops of the Arbuckle-Simpson aquifer in the Arbuckle Mountains.

Evidence of long-distance transport of mountain cedar pollen into Tulsa, Oklahoma  

NASA Astrophysics Data System (ADS)

Previous study of Cupressaceae pollen in the Tulsa atmosphere during December and January suggested that the source of this pollen is the Juniperus ashei (mountain cedar) populations that occur mainly in southern Oklahoma and central Texas. The present investigation examined the evidence of long-distance transport of pollen from these populations during the 1996/1997 season at three sites in Oklahoma using Burkard traps. Two of the pollen-monitoring stations were operated in conjunction with Mesonet meteorological stations. It was found that the December and January Cupressaceae pollen occurs outside of the local season at Tulsa. Pollen concentrations are intermittent and correspond to days of peak concentrations at sites nearer the mountain cedar populations. Peak concentrations are associated with winds coming from the south over the mountain cedar areas. Diurnal rhythms show night-time peaks with a delay in timing at the northern-most site. These results are all consistent with the hypothesis that pollen is being transported over long distances from the mountain cedar populations to Tulsa, Oklahoma. These findings are important as they represent one of the few incidences of long-distance transport of pollen in significant concentrations to an area where the source vegetation is not present. Pollen-monitoring sites located in conjunction with Mesonet meteorological stations provide a unique opportunity to further examine atmospheric conditions during long-distance transport events. This will aid future studies of the spatial modeling of long-distance dispersal of pollen.

Testing a Mahalanobis distance model of black bear habitat use in the Ouachita Mountains of Oklahoma  

USGS Publications Warehouse

Regional wildlife-habitat models are commonly developed but rarely tested with truly independent data. We tested a published habitat model for black bears {Ursus americanus) with new data collected in a different site in the same ecological region (i.e., Ouachita Mountains of Arkansas and Oklahoma, USA). We used a Mahalanobis distance model developed from relocations of black bears in Arkansas to produce a map layer of Mahalanobis distances on a study area in neighboring Oklahoma. We tested this modeled map layer with relocations of black bears on the Oklahoma area. The distributions of relocations of female black bears were consistent with model predictions. We conclude that this modeling approach can be used to predict regional suitability for a species of interest.

Structural style and timing of Late Paleozoic basement uplifts in southern Oklahoma  

SciTech Connect

Proposed theories of deformation in southern Oklahoma presently involve large-scale basement thrusting or large magnitudes of strike slip. As more and better seismic data and well control have become available, a predominant interpretation of the structural style is emerging. This style is characterized by a large basement overhang along the mountain fronts, created by major reverse dip-slip (thrust) faults. Additionally, these reverse faults may have an antithetic back-thrust on the hanging wall. In cross section, this style appears as a wedge-uplift that is often mistakenly interpreted to represent the upper portion of a flower structure created by wrench-faulting. Structural uplifts in southern Oklahoma developed as a result of Late Paleozoic Wichita, Ouachita and Arbuckle orogenies. Emplacement of the thin-skinned Ouachita thrust belt occurred during the Ouachita orogeny (Mississippian through Middle Pennsylvanian). Basement-involved compressional uplifts of the Wichita Mountains and Criner Hills were initially uplifted during the Wichita orogeny (Late Mississippian to Early Pennsylvanian), while the Arbuckle anticline and Tishomingo uplift reached their culmination during the Arbuckle orogeny (Middle to Late Pennsylvanian). Evidence for the timing of these uplifts are the various conglomerates and unconformities preserved in the subsurface, and occasionally exposed at the surface. Age-dating of these unconformities strongly suggests a sequence of deformation in which the culmination of uplift progressed generally from south to north through time. This sequence is also suggested by deformation of the thin-skinned Ouachita thrust belt by basement-involved structures of the Arbuckle orogeny.

Water Decisions for Sustainability of the Arbuckle-Simpson Aquifer  

NASA Astrophysics Data System (ADS)

The Arbuckle-Simpson Aquifer in south-central Oklahoma, situated in the heart of the Chickasaw Nation, is the state's only sole-source groundwater basin and sustains the Blue River, the state's only freeflowing river. The recent comprehensive hydrological studies of the aquifer indicate the need for sustainable management of the amount of water extracted. However, the question of how to deal with that management in the face of increasing drought vulnerability, diverse demands, and climate variability and change remains. Water management carries a further imperative to be inclusive of tribal and non-tribal interests. To address these issues, this interdisciplinary project takes an integrated approach to understanding risk perceptions and water decisions for sustainability of the Arbuckle-Simpson Aquifer. Our interdisciplinary research asks: How do stakeholders in the Arbuckle-Simpson Aquifer perceive drought risks across weather and climate scales, and how do these perceptions guide water management decisions given (i) diverse cultural beliefs, (ii) valued hydrologic services, (iii) past drought experience, and (iv) uncertainties in future projection of precipitation and drought? We will use ethnographic methods to diagnose how cultural values and beliefs inform risk perceptions, and how this in turn guides decision making or ignites conflict across different sectors and stakeholder groups. Further, the characterization of drought risk will be examined in the context of historic meteorological and hydrologic events, as well as climate variability and change. This will identify which risks are prioritized, and under what conditions, in regional decision making or water-related conflicts.

Post-carboniferous tectonics in the Anadarko Basin, Oklahoma: Evidence from side-looking radar imagery  

NASA Technical Reports Server (NTRS)

The Anadarko Basin of western Oklahoma is a WNW-ESE elongated trough filled with of Paleozoic sediments. Most models call for tectonic activity to end in Pennsylvanian times. NASA Shuttle Imaging Radar revealed a distinctive and very straight lineament set extending virtually the entire length of the Anadarko Basin. The lineaments cut across the relatively flat-lying Permian units exposed at the surface. The character of these lineaments is seen most obviously as a tonal variation. Major streams, including the Washita and Little Washita rivers, appear to be controlled by the location of the lineaments. Subsurface data indicate the lineaments may be the updip expression of a buried major fault system, the Mountain View fault. Two principal conclusions arise from this analysis: (1) the complex Mountain View Fault system appears to extend southeast to join the Reagan, Sulphur, and/or Mill Creek faults of the Arbuckle Mountains, and (2) this fault system has been reactivated in Permian or younger times.

Relationship of facies and sequence stratigraphy to Paleokarst and fracture overprints in the carbonates of the Arbuckle Group in the evaluation of exploration and horizontal drilling potential  

SciTech Connect

The mid-continent region, especially in Oklahoma and Arkansas, contains thick dolomite Paleozoic carbonate sections with karstic character. These sections commonly exhibit strong structural overprints, including intense fracturing, due primarily to Pennsylvanian orogenies. The Arbuckle Group is compose of multiple parasequences that are the result of cyclic peritidal deposition on a broad shallow shelf. Sequence stratigraphy evaluation indicates that significant unconformities or disconformities occur within the Arbuckle Group along third-order sequence boundaries. Arbuckle carbonates were subjected to very early dolomitization (Ordovician through Devonian). Sequences in which intercrystalline porosity was developed with little or no vuggy porosity usually have low permeability and effective porosity. However, these dolomitic sequences are quite susceptible to fracturing and they may produce in structural traps. These fractured sequences in the Arbuckle also are particularly susceptible to karstification associated with multiple unconformities, especially in areas where there has been significant orogenic activity such as the Criner uplift in southern Oklahoma. Fracturing and subsequent karstification have significant influence on porosity development and can produce extremely heterogeneous reservoirs. Exploration for oil and gas in the Arbuckle Group has been a difficult task. Problems with seal and source along with complex diagenetic and structural histories still plague efforts to understand Arbuckle reservoir development. There is new evidence that dolomitization, fracturing and karstification may be related to particular sequence positions and their related facies and disconformities. Innovative advances in geologic concepts, such as sequence stratigraphy, and in techniques, such as horizontal drilling, may lead to new discoveries in the Arbuckle Group.

Pennsylvanian foreland deformation of Wichita uplift, southwest Oklahoma  

SciTech Connect

Pennsylvanian foreland deformation associated with the Ouachita orogene reactivated a west-northwest-east-southeast Cambrian basement trend, the southern Oklahoma aulacogen, to form the Wichita uplift, southwest Oklahoma. The 30-km-wide subsurface Frontal fault zone separates the uplift from the Anadarko basin to the north. Horizontal shortening across this fault zone is estimated at 7-15 km (20-40%), vertical displacement totals 9-10 km from the uplift to the basin. Folds are mapped on an interformational scale within the Frontal fault zone, and on an intraformational scale (Cambro-Ordovician Arbuckle Group) in the Slick Hills, southwest Oklahoma. Additional shortening occurred along southwest dipping mountain flank thrusts and on bedding plane thrusts, respectively. Hanging wall blocks of major faults contain the shallow dipping limb and anticlinal hinge zone of the interformational scale folds. Oil and gas production is generally restricted to these anticlinal crests within Paleozoic rocks. Deep wells (> 6000 m) that have penetrated footwall imbricates of the mountain flank thrusts have drilled through steep-overturned beds and tight recumbent folds before passing through faults into a normal stratigraphic sequence. Basement thrust loading of the southern margin of the Anadarko basin controlled the trend (west-northwest-east-southeast) of the axis of maximum deposition within the basin during the Pennsylvanian.

COCORP profiling across the Southern Oklahoma aulacogen: Overthrusting of the Wichita Mountains and compression within the Anadarko Basin  

NASA Astrophysics Data System (ADS)

COCORP (Consortium for Continental Reflection Profiling) deep reflection profiles recorded across the Wichita Mountains and Anadarko Basin suggest that significant crustal shortening occurred in the final stages of the evolution of the Southern Oklahoma aulacogen. The crystalline rocks of the Wichita Mountains were thrust in Pennsylvanian time northeastward over sedimentary rocks of the Anadarko Basin along a series of faults with moderate (average 30° to 40°) and southwesterly dips. These faults can be traced possibly as deep as 20 to 24 km. Listric thrust faults and hanging-wall anticlines developed in the sedimentary rocks of the basin. These features contrast with conventional interpretations of Pennsylvanian structures as the result of predominantly vertical movements along high-angle faults, and they suggest that Pennsylvanian downwarping of the Anadarko Basin was at least partially due to thrust loading. Truncations of reflections from Cambrian-Ordovician rocks in the deepest part of the basin suggest normal faulting, which would support ideas of an early extensional stage in the aulacogen cycle. The distinctive Precambrian layering seen on earlier COCORP data recorded south of the Wichita Mountains cannot be recognized under the Anadarko Basin, and the Proterozoic basin containing that layering may have been bounded on its north side by a Precambrian fault. This inferred fault was probably twice reactivated during formation of the Southern Oklahoma aulacogen—once during late Precambrian(?)-Early Cambrian extension, and again during Pennsylvanian compression. The popular view that aulacogens originated from radial rifting of updomed, homogeneous continental crust is probably too simplified, and a more important constraint on their location and development may be the nature of pre-existing lines of weakness. *Present address: Department of Earth Sciences, Cambridge University, Cambridge CB3 OEZ, England

Quebec Cambro-Ordovician exploration focuses on Wilburton Arbuckle analog  

SciTech Connect

This paper reports that Quebec is the site of key Cambro-Ordovician wildcatting and lower risk gas drilling. A group of companies is below 7,000 ft at 1 St. Simon, a wildcat in the St. Lawrence Lowlands basin projected to Cambrian Potsdam sand at about 13,800 ft. The drill site is on part of the ancient Cambro-Ordovician coastline from Newfoundland through Quebec and the eastern U.S. to West Texas. Bow Valley Industries Ltd. is operator of the well on a prospect assembled by Exploration Terrenex Ltd., Calgary. The companies say the area south of the St. Lawrence River is a depositional and structural look-alike to Wilburton deep field in the Arkoma basin of eastern Oklahoma, where the gas productive Ordovician carbonate is the Arbuckle.

The mid-continent region, especially in Oklahoma and Arkansas, contains thick dolomite Paleozoic carbonate sections with karstic character. These sections commonly exhibit strong structural overprints, including intense fracturing, due primarily to Pennsylvanian orogenies. The Arbuckle Group is compose of multiple parasequences that are the result of cyclic peritidal deposition on a broad shallow shelf. Sequence stratigraphy evaluation indicates that significant unconformities

The Central Kansas uplift is a collapsed arch which was eroded to granite on both sides of a central graben during the post-Mississippian. Uplift and collapse produced a myriad of horst anad graben blocks affecting the Arbuckle Group below the so-called pre-Pennsylvanian unconformity. Arbuckle production comes from horst blocks, and about 75% of the Arbuckle production on the uplift comes from blocks within the central graben. Mapping Arbuckle structures as fault blocks rather than as erosional features allows a completely different use of subsurface data and can lead to many unsuspected field extension and wildcat prospects.

Sterane distribution of solid bitumen pyrolyzates. Changes with biodegradation of crude oil in the Ouachita Mountains, Oklahoma  

NASA Astrophysics Data System (ADS)

Solid bitumens (grahamite and impsonite) of southeastern Oklahoma have been shown to originate from near-surface alteration of crude oil ( CURIALE, 1981; CURIALE and HARRISON, 1981). Pyrolysis of these solids has been employed to compare the sterane distribution of geographically proximate oils to that of the bitumens. The ratio of rearranged to regular steranes is higher in the pyrolyzates than in the oils, a finding consistent with a bitumen origin due to biodegradation of oil. The remaining presence of steranes, particularly regular steranes, in the bitumens suggests that sterane occlusion may have occurred prior to or during the alteration process, thus removing tetracyclic compounds from the influence of microbial attack. These data suggest that pyrolysis- GC/MS offers a viable approach to correlation problems involving solid bitumens.

Rotation of fold-hinge lines associated with simple shear during southerly directed thrusting, Ouachita Mountains, southeastern Oklahoma  

NASA Astrophysics Data System (ADS)

The Broken Bow uplift in southeastern Oklahoma contains the oldest rocks exposed in Ouachita orogenic belts and has experienced tour phases of deformation. First generation folds are tight, overturned, Sverging. and have a well developed slaty cleavage. Second-generation folds are coaxial with first-generation structures, are open to tight, are inclined, and reveal S-vergence. Northerly dipping faults truncate second generation fold limbs. Third-phase structures, including recumbent folds and pencil structures, are interpreted to be contemporaneous with S-directed thrusting. The hinges of earlier folds documented in the area least affected by thrusting are horizontal and trend E-W. The hinges of folds of the same generation within fault zones plunge 30-50 ° toward the north or northwest. Thus, it is concluded that the earlier folds have been passively rotated during S-direeted thrusting, as have the contemporaneous folds and pencil structures. A simple-shear model associated with S-directed thrusting is proposed to explain these geometrical relations. The rotated fold hinges provide quantifiable shear-strain gauges which can be used to quantify shear strain in the Broken Bow uplift as well as in other orogenic belts. A model for shear-strain calculation is developed using the general geometric relationship between fold-hinge lines, the shear direction, and the shear plane.

National Uranium Resource Evaluation: Enid Quadrangle, Oklahoma and Kansas  

SciTech Connect

The uranium resources of the Enid Quadrangle, Oklahoma and Kansas, were evaluated to a depth of 1500 m using the available surface and subsurface geologic information, supplemented with an intensive geologic and geochemical reconnaissance of the quadrangle. Uranium occurrences reported in the literature were located, sampled, and described in detail. Areas of anomalous radioactivity and areas of known copper mineralization were also investigated for uranium potential. One previously known occurrence and one new occurrence were investigated in detail. All mineralized areas occur in Upper Pennsylvanian and Lower Permian strata and are uneconomic. All surface and subsurface rocks in the quadrangle are considered to possess characteristics unfavorable for uranium potenial. The upper Arbuckle Group (Upper Cambrian-Lower Ordovician) was designated as an unevaluated environment. The Arbuckle has some favorable characteristics, but sufficient information is not available to consider it an environment favorable for uranium deposits.

Post-Pennsylvanian reactivation along the Washita Valley fault, southern Oklahoma  

SciTech Connect

Surface exposures of faults of the Washita Valley fault (WVF) system in Garvin, Murray, Carter, and Johnston counties of southern Oklahoma were studied to determine if there has been post-Pennsylvanian fault reactivation and to determine if there has been any Quaternary fault movement. This was undertaken through field mapping, by dating alluvium which overlies the faults, and by logging trenches excavated across the WVF. In northern Murray County and southern Garvin County (site A), the WVF displaces Late-Pennsylvanian Oscar Group showing post-Pennsylvanian movement; however, no faulting was observed in 2000 year old alluvium of Wildhorse Creek along strike of the WVF. Three sites (B, C, and D) are located within the Arbuckle Mountains. Faulting of Virgilian age Vanoss Conglomerate and Vanoss Shale reveal post-Virgilian (Late Pennsylvanian) activity along a subsidiary fault in northern Murray County (site B). A 12000 to 15000 year old terrace at this site is unfaulted. Absence of any fault related features in paleosols which overly the WVF along the Washita River (site C) show that the fault has not been active during the last 1570 /+-/ 190 years in southern Murray County. Similarly, absence of any fault related features along Oil Creek (site D) indicates that the WVF has not been active during the last 1810 /+-/ 80 years in northern Carter and Johnston Counties. Faults in the Antlers Sandstone in southern Johnston County (site E) reveal post-Lower Cretaceous reactivation of the WVF. 49 refs., 28 figs., 1 tab.

Alterations in the non-clay-mineral fraction of pelitic rocks the diagenetic to low-grade metamorphic transition, Ouachita Mountains, Oklahoma and Arkansas  

SciTech Connect

The transformation of smectite to illite has been cited by many authors as a source of silica during diagenesis of mudrocks. Illites themselves, however, undergo chemical changes as they recrystallize into micas during high-grade diagenesis/low-grade metamorphism. Average compositions of phyllosilicates from the literature suggest that an equivalent amount of silica is available from transformation of illite to muscovite as from illitization of smectites. The fate of silica released by this process has not been reported, but could be a major contributor to the silt-size quartz population. The quartz and feldspar fraction of pelites from the Stanley Shale (Mississippian) in the Ouachita Mountains of Oklahoma and Arkansas was separated using sodium bisulfate fusions. The mineralogy and the grain-size distribution of this fraction were determined using standard petro-graphic and X-ray diffraction (XRD) techniques. Bulk rock samples were analyzed using X-ray fluorescence (XRF) and instrumental neutron activation analysis (INAA) methods. The data obtained were related to illite crystallinity and vitrinite reflectance as reported by Guthrie el al. (1986) and Houseknecht and Matthews (1985). The authors results are consistent with reported differences between quartz in schists and their shale precursors, and suggest that release of silica during diagenesis of phyllosilicates continues after the smectite-illite transformation. This silica precipitates as quartz within the pelite, consistent with the suggestion by Blatt (1987) that metapelites are the source of abundant silt-size quartz. The lack of whole-rock chemical variation with thermal maturity implies closed-system behavior across much of the pelite-to-metapelite transition.

New constraints on the age and depositional rates of initial flysch sedimentation in the Stanley Group, Ouachita Mountains, Oklahoma and Arkansas  

NASA Astrophysics Data System (ADS)

The transition from a 'starved basin' to classic orogenic flysch deposition of Paleozoic strata in the Ouachita Mountains of Oklahoma and Arkansas and the absolute timing of mountain building events associated with the Ouachita Orogeny have long been unresolved problems in the region. The Mississippian Stanley Group is an important sedimentary unit within the Paleozoic strata because, unlike the other Paleozoic units in the Ouachita Mountains, the Stanley Group contains several dateable tuffaceous units. LA-ICPMS analyses of zircons from 5 tuffaceous units show progressively younger weighted average ages: Beaver's Bend Tuff (328.3±2.9 Ma), Hatton Tuff (327.5±3.8 Ma), lower Mud Creek Tuff (321.9±2.0 Ma), upper Mud Creek Tuff (326±3.2Ma) and Chickasaw Creek Tuff (320.6±2.7Ma). The exception is the upper Mud Creek Tuff (326 Ma), which has a more significant detrital component when compared to the other tuffaceous units. The ages of the Beaver's Bend, Hatton, lower and upper Mud Creek tuffs agree with previously reported biostratigraphic data found in the lower 500m of the Stanley Group (Ethington, 1989), which suggest an early Mississippian age for its lower boundary. The top 250 meters contain the Chickasaw Creek tuff (320.6±2.7 Ma) which indicates a late Mississippian age for the top of the Stanley Group. The transition from a 'starved basin' is marked by a sudden increase in clastic detritus entering the Ouachita Trough. A regional hiatus (Noble, 1993) is known to exist at the boundary between the base of the Stanley Group and the upper Devonian Arkansas Novaculite. The tuff ages, coupled with the biostratigraphic data, indicate that sedimentation rates were low (<20m/Ma) through the deposition of the Beaver's Bend tuff (328.3±2.9 Ma), after which sedimentation rates increased to >2500m/Ma by the time the Chickasaw Creek tuff (320.6±2.7Ma) was deposited. The sedimentation rates remain high (~900m/Ma) through the deposition of the stratigraphically higher units: Jackfork Group, Johns Valley and Atoka formations which are all considered to be pre-orogenic (King, 1961). These new data constrain the timing of significant increases in sedimentation rates in a remnant ocean basin (Ouachita trough) that are likely associated with longitudinal transport (e.g. Graham et al., 1975) and dispersal of sediment from sequential (diachronous) collision.

Porosity development in quartz-rich, oolitic limestones of upper Arbuckle Group: A response to unloading  

SciTech Connect

The upper Arbuckle Group of southern Oklahoma is composed of a thick sequence of carbonates deposited in shallow, epicontinental seas. Several concentrations of quartz sandy detritus, two of which are significant markers in outcrop, are found in the Kindblade and Cool Creek Formations. Both units are composed of varying amounts of quartz sand, ooids, peloids, clasts, and micrite matrix cemented by calcite, silica, and minor dolomite. After a complex postdepositional history of burial, tectonism, and uplift, removal of overburden resulted in relaxation of compressive forces and the development of microfractures between and within grains in the mixed mineralogy units. Equidimensional voids formed around the outer edges of syntaxial quartz overgrowths as calcite spar separated from silica spar. Relatively thin cortices pulled away from large nuclei resulting in spherical voids within ooids. Multiple microfractures in the radial cortices connect the inner spherical pores to interparticle porosity. A system of microfractures between crystal boundaries in the calcite cement links the pores. Porosity development varies laterally within the quartz sandy, oolitic units and is, in part, dependent on the original burial depth and the amount of overburden removed. Microfractures in subsurface units, if present, may not be as well developed. Alternatively, microfracturing may be enhanced as a result of subsurface dissolution.

Petroleum geology of Ouachita uplift region of Oklahoma  

SciTech Connect

Two major petroleum plays are found in the Ouachita uplift region. Folded and thrusted strata constitute the shallower, and possibly the more extensive, of the two. Developed reservoirs include Bigfork Chert (Ordovician), Arkansas Novaculite (Devonian-Mississippian), sandstones within Stanley (Mississippian) and Jackfork (Morrowan) Groups, and Wapanucka Limestone-Spiro Sandstone (Morrowan-Atokan). The deeper play is characterized by underlying basement fault blocks. Development in the Arkoma basin indicates that major reservoirs will include Arbuckle group carbonates. This play is limited to the south by increasing depth and by seismic resolution of the fault blocks. Other potential reservoirs in both plays include Crystal Mountain and Blakely Sandstones (Ordovician), and Blaylock Sandstone (Silurian), with progressively older strata involved in thrusting southward across the uplift. The eastward extent of the Arbuckle facies of lower Paleozoic strata remains a major question.

Petroleum production and exploration in Ouachita region of Oklahoma  

SciTech Connect

Petroleum production in the Ouachita region of southeastern Oklahoma occurs in three geographic areas parallel to regional structure. The frontal gas, central oil, and central gas belts are distinguished by differences in structural setting, reservoir strata, and types of hydrocarbons. In the frontal belt, nearly 1 trillion ft/sup 3/ of dry gas has been produced from thrusted and subthrust Morrowan and Atokan sandstone and carbonate reservoirs. Over 8000 bbl of oil have been produced in the central oil belt, southeast of the Ti Valley fault. Structures consist of imbricate thrusts and isoclinal to overturned folds. The fields are typically small, associated with asphaltite or tar sands, and produce from Carboniferous sandstone reservoirs. Farther southeast, small fields within the central gas belt have produced minor gas from Ordovician, Devonian, and Mississippian reservoirs. Six Ordovician through Mississippian Ouachita-facies shales are potential petroleum source rocks and occur in the middle to lower part of the oil window. However, Devonian and Mississippian strata are composed primarily of terrestrial organic matter and are probably gas prone. Oil in Carboniferous reservoirs probably migrated upward stratigraphically from older sources. Recent exploration has focused on extending production from Pennsylvanian reservoirs in the frontal gas belt. However, a significant Arbuckle discovery (ARCO 2 Yourman) and a Broken Bow uplift test (Sohio 1-22 Weyerhauser) in 1987 indicate that Cambrian-Ordovician Arbuckle Group carbonates may be prospective beneath all of the Oklahoma Ouachitas. Near-future rank-wildcat exploration will probably focus on subthrust, structurally and stratigraphically favorable Arbuckle plays.

Left-lateral intraplate deformation along the ancestral rocky mountains: Implications for late paleozoic plate motions  

NASA Astrophysics Data System (ADS)

North America underwent synchronous orogenic events during the late Paleozoic along its eastern margin (Alleghanian orogeny), southern margin (Ouachita orogeny), and within the southwestern part of the continent (Ancestral Rocky Mountain orogeny). All three orogenies were initiated in the late Mississippian to early Pennsylvanian, reached the greatest intensity in the middle Pennsylvanian, and ended in the early Permian. The Alleghanian and Ouachita orogenies have been related to the closing of the proto-Atlantic and the collision between North America and South America-Africa: it is here proposed that the Ancestral Rocky Mountains were produced by a collision between eastern North America and Africa. The Ancestral Rockies were formed as the result of reactivation of the Wichita megashear, a preexisting zone of weakness that extends from southern Oklahoma to eastern Utah. Previous plate tectonic models have implied that the megashear was a zone of right-lateral strike-slip faulting and north-northwest-directed compression. However, structural and stratigraphic data from Oklahoma and Texas suggest that the Wichita megashear was a major left-lateral fault zone formed under east-northeast-oriented compression. Palinspastic reconstruction of pre-mid-Devonian strata across the megashear in Texas indicates that 120 to 150 km of left slip occurred during the Desmoinesian (middle Pennsylvanian). The proposed plate tectonic model for the Ancestral Rocky Mountain orogeny includes: (1) movement of the North American plate eastward from a spreading center in the proto-Pacific; (2) closing of the proto-Atlantic Ocean; (3) collision of North America-Europe (Laurussia) and South America-Africa (Gondwana) resulting in the Hercynian, Alleghanian, and Ouachita orogenies; (4) differential movement across the Wichita megashear and formation of a left-lateral strike-slip fault zone (Ancestral Rocky Mountain orogeny) as the result of east-west compression within the North American plate: (5) relative northward movement of Gondwana against Laurussia producing the Marathon and Arbuckle orogenies; and (6) development of a subduction zone to the west of the North American continent.

Mississippian facies relationships, eastern Anadarko basin, Oklahoma  

SciTech Connect

Mississippian strata in the eastern Anadarko basin record a gradual deepening of the basin. Late and post-Mississippian tectonism (Wichita and Arbuckle orogenies) fragmented the single large basin into the series of paired basins and uplifts recognized in the southern half of Oklahoma today. Lower Mississippian isopach and facies trends (Sycamore and Caney Formations) indicate that basinal strike in the study area (southeastern Anadarko basin) was predominantly east-west. Depositional environment interpretations made for Lower Mississippian strata suggest that the basin was partially sediment starved and exhibited a low shelf-to-basin gradient. Upper Mississippian isopach and facies trends suggest that basinal strike within the study area shifted from dominantly east-west to dominantly northwest-southeast due to Late Mississippian and Early Pennsylvanian uplift along the Nemaha ridge. Within the study area, the Chester Formation, composed of gray to dove-gray shales with interbedded limestones deposited on a carbonate shelf, thins depositionally into the basin and is thinnest at its facies boundary with the Springer Group and the upper portion of the Caney Formation. As basin subsidence rates accelerated, the southern edge of the Chester carbonate shelf was progressively drowned, causing a backstepping of the Chester Formation calcareous shale and carbonate facies. Springer Group sands and black shales transgressed northward over the drowned Chester Formation shelf.

Helicopter electromagnetic and magnetic geophysical survey data, Hunton anticline, south-central Oklahoma  

USGS Publications Warehouse

This report is a digital data release for multiple geophysical surveys conducted in the Hunton anticline area of south-central Oklahoma. The helicopter electromagnetic and magnetic surveys were flown on March 16–17, 2007, in four areas of the Hunton anticline in south-central Oklahoma. The objective of this project is to improve the understanding of the geohydrologic framework of the Arbuckle-Simpson aquifer. The electromagnetic sensor for the helicopter electromagnetic survey consisted of six different transmitter-receiver orientations that measured the earth's electrical response at six distinct frequencies from approximately 500 Hertz to approximately 115,000 Hertz. The electromagnetic measurements were converted to electrical resistivity values, which were gridded and plotted on georeferenced maps. The map from each frequency represents a different depth of investigation for each area. The range of subsurface investigation is comparable to the depth of shallow groundwater. The four areas selected for the helicopter electromagnetic study, blocks A–D, have different geologic and hydrologic settings. Geophysical and hydrologic information from U.S. Geological Survey studies are being used by modelers and resource managers to develop groundwater resource plans for the Arbuckle-Simpson aquifer.

The geologic map includes revisions of numerous unit contacts and faults and a number of previously “undifferentiated” rock units were subdivided in some areas. Numerous circular-shaped hills in and around Chickasaw National Recreation Area are probably the result of karst-related collapse and may represent the erosional remnants of large, exhumed sinkholes. Geospatial registration of existing, smaller scale (1:72,000- and 1:100,000-scale) geologic maps of the area and construction of an accurate Geographic Information System (GIS) database preceded 2 years of fieldwork wherein previously mapped geology (unit contacts and faults) was verified and new geologic mapping was carried out. The geologic map of Chickasaw National Recreation Area and this pamphlet include information pertaining to how the geologic units and structural features in the map area relate to the formation of the northern Arbuckle Mountains and its Arbuckle-Simpson aquifer. The development of an accurate geospatial GIS database and the use of a handheld computer in the field greatly increased both the accuracy and efficiency in producing the 1:24,000-scale geologic map.

Geology of the Cottonwood Creek field, Carter County, Oklahoma  

SciTech Connect

In late 1987, the Cottonwood Creek field, Carter County, Oklahoma, was heralded by flows of nearly 4,000 BOPD and 3 MMCFGD from the upper Arbuckle Group. The field structure is part of the buried Criner uplift along the southwest flank of the Ardmore basin. The uplift formed during a Late Mississippian/Early Pennsylvanian episode of bidirectional thrusting (northeast and southwest) probably related to convergent strike-slip faulting. The basic field structure formed as a northeast-directed thrust plate, cored with Arbuckle Group carbonates and cut by a backthrust. The Cottonwood Creek anticline was near the crest of the uplift. It was erosionally denuded of its Simpson through Caney cover and karsted to depths of at least 1,600 ft. Subthrust strata include the Woodford source rocks. In the Middle to Late Pennsylvanian the uplift was buried by clastics (about 8,000 ft thick over cottonwood Creek). Culminating in the late Pennsylvanian, a second episode of wrench faulting sliced through the Criner uplift. About 3 mi of left-lateral slip occurred on this Criner-Healdton fault, which also dropped the anticline about 3,000 ft relative to the block to the south, completing the trap at Cottonwood Creek field. Fourteen wells have found oil in the anticline over an approximately 2.5 by 0.5-mi area. The oil column is at least 900 ft thick. Eight of the wells tested for 1,200-3,700 BOPD plus associated gas from a complex of fractures, Brown Zone dolomite, and karst-enhanced porosity in the West Spring Creek and Kindblade formations.

Petrological and Geochemical Studies of Samples from the Nicor Chestnut 18-4 Drill Core, AMES Impact Structure, Oklahoma  

NASA Astrophysics Data System (ADS)

The near-circular 15-km-diameter Ames structure is located at 36 degrees 15' N and 98 degrees 12' W in southeastern Major County (NW Oklahoma). The structure, which is set in Cambro-Ordovician Arbuckle dolomite, consists of two concentric rims, an outer rim, which is about 1.5 to 3 km wide, and an inner "rim". The rocks of the outer rim consist mainly of fractured and brecciated Arbuckle dolomite. The inner "ring" (about 5 km in diameter) seems to be the eroded remnant of a central structural uplift, with rocks comprising brecciated Precambrian granite and Arbuckle dolomite. The depression is covered by Middle Ordovician Oil Creek shale. The structure is penetrated by a number of oil- and gas-producing wells in the crater rim and the central uplift. The production from these wells indicate that Ames represents one of the largest - if not the largest - single oil fields in Oklahoma. Currently the structural disturbance is buried beneath almost 3000 m of sedimentary rock. The origin of the structure has been intensely debated since the discovery of the structural anomaly, but geophysical and geological, as well as petrological and geochemical data provide very good evidence that it was formed by impact, and not by volcanism or even more esoteric processes. In the present study, we analyzed 17 samples, including impact melt breccia, from the Nicor Chestnut 18-4 core. These samples represent the largest and best examples of impact melt breccias and melt rock obtained so far from the Ames structure. One important result of the petrographic analyses is the observation that not all carbonate rocks postdate the impact, but some were clearly present among the target rocks. The chemical composition of the impact melt breccias is similar to that of other melt rocks from the Dorothy 1-19 core, as well as to the target granite, with variable carbonate admixtures. Some impact melt rocks are enriched in siderophile elements, indicating a possible meteoritic component.

Regional variations in crude oil geochemistry, Anadarko basin, Oklahoma, Texas, and Kansas - evidence for multiple sources, mixing, and migration distances  

SciTech Connect

Geochemical analyses of 96 crude oil and condensate samples from the deep Anardarko basin and adjacent shelf areas show three major oil types, which generally correlate with reservoir age. Analyses include C/sub 3/-C/sub 30/ whole oil gas chromatography, C/sub 10/ + saturated hydrocarbon fraction gas chromatography, carbon stable isotopes (ppt relative to PDB) of saturated (sat) and aromatic (arom) hydrocarbon fractions, and computerized GC/MS of selected samples. Three samples from Ordovician Simpson Group reservoirs are typical Ordovician oils (type 1), having strong odd-carbon predominance in the C/sub 13/ to Cr/sub 19/ n-alkanes, containing little or no acyclic isoprenoids, and delta/sup 13/C of -33.9 ppt (sat) and -33.7 ppt (arom). Oils from Devonian and Mississippian reservoirs (type 2) show little or no odd-carbon predominance in the n-alkanes, an exponential decrease in abundance with increasing carbon number, pristane/phytane ratios (pr/ph) of 1.1 to 1.5, and delta/sup 13/C of -30.6 (sat) and -30.1 ppt (arom). Oils in Pennsylvanian reservoirs (type 3) have the greatest amounts of C/sub 15/ + hydrocarbons of all the oils, are isotopically heavy (-27.5 ppt (sat) and -26.4 ppt (arom)), have methyl-cyclohexane as the most abundant hydrocarbon, and have pr/ph values from 1.8 to 0.9 Type 3 oils with pr/ph < 1 form a subgroup in the Texas and Oklahoma panhandles. Condensates correlate with the three oil types based on carbon isotopic and gasoline-range compositions. Oils of type 2 composition occur in rocks of Ordovician to Pennsylvanian age in complex structural traps near the Arbuckle Mountains and in subcrop plays where Pennsylvanian reservoirs directly overlie Devonian and older rocks. Such traps also contain oils that could be mixtures of types 2 and 3 and types 1 and 2. Oils from the Kansas shelf are similar to the Anadarko oil types except that they have only traces of toluene and no detectable benzene.

Oklahoma seismic network. Final report  

SciTech Connect

The US Nuclear Regulatory Commission has established rigorous guidelines that must be adhered to before a permit to construct a nuclear-power plant is granted to an applicant. Local as well as regional seismicity and structural relationships play an integral role in the final design criteria for nuclear power plants. The existing historical record of seismicity is inadequate in a number of areas of the Midcontinent region because of the lack of instrumentation and (or) the sensitivity of the instruments deployed to monitor earthquake events. The Nemaha Uplift/Midcontinent Geophysical Anomaly is one of five principal areas east of the Rocky Mountain front that has a moderately high seismic-risk classification. The Nemaha uplift, which is common to the states of Oklahoma, Kansas, and Nebraska, is approximately 415 miles long and 12-14 miles wide. The Midcontinent Geophysical Anomaly extends southward from Minnesota across Iowa and the southeastern corner of Nebraska and probably terminates in central Kansas. A number of moderate-sized earthquakes--magnitude 5 or greater--have occurred along or west of the Nemaha uplift. The Oklahoma Geological Survey, in cooperation with the geological surveys of Kansas, Nebraska, and Iowa, conducted a 5-year investigation of the seismicity and tectonic relationships of the Nemaha uplift and associated geologic features in the Midcontinent. This investigation was intended to provide data to be used to design nuclear-power plants. However, the information is also being used to design better large-scale structures, such as dams and high-use buildings, and to provide the necessary data to evaluate earthquake-insurance rates in the Midcontinent.

Oklahoma Healthy Homes Initiative  

PubMed Central

Compelling scientific evidence suggests that a strong association exists between housing-related hazards and the health and safety of their residents. Health, safety, and environmental hazards (such as asthma and allergy triggers), unintentional injury hazards, lead-based paint hazards, and poor indoor air quality are interrelated with substandard housing conditions. This article describes a Healthy Homes initiative to address these hazards in a coordinated fashion in the home, rather than taking a categorical approach, even in the presence of multiple hazards. It also provides an overview of Oklahoma's Healthy Homes initiative and its pilot project, the Tulsa Safe and Healthy Housing Project, which is currently administered in Tulsa in collaboration with Children First, Oklahoma's Nurse-Family Partnership program. This pilot project seeks to open new areas of research that can lead to a greater understanding of environmental health issues related to substandard housing in the United States, which will eventually make homes safer and healthier.

Heat flow in Oklahoma  

SciTech Connect

Oklahoma is one area in which terrestrial heat flow data are sparse. The thermal state of the southern mid-continent, however, is a key to understanding several important geologic problems. These include thermal anomalies associated with Paleozoic fluid migrations and the formation of Mississippi Valley-type lead-zinc deposits, the thermal evolution of the Arkoma and Anadarko sedimentary basins, and the history of hydrocarbon generation and overpressuring in the Anadarko Basin. In the late 1920s, the American Petroleum Institute made a set of equilibrium temperature logs in idle oil wells. These temperature data are generally regarded as being high quality, accurate estimates of rock temperature and they cover the entire central part of Oklahoma. Average thermal gradients in the API survey range from 14 to 43 [sup 0]C/km (average 31.2 [sup 0]C/km) over depth intervals that extend from the surface to a an average depth of 961 m. Geothermal gradients decrease from NNE to SSW. The observed change in thermal gradients could be due to a number of factors. The change in thermal gradients could simply reflect changes in lithology and thermal conductivity. Alternatively, the variation in thermal gradients could be indicative of a change in heat flow related perhaps to variations in the concentration of radioactive heat-producing elements in the crust or heat transport by one or more regional groundwater flow systems. We are proceeding to reduce ambiguity in interpretation by estimating heat flow from thermal conductivity measurements on drill cuttings and heat production from available gamma-ray logs which penetrate basement rocks.

MISR Scans the Texas-Oklahoma Border  

NASA Technical Reports Server (NTRS)

These MISR images of Oklahoma and north Texas were acquired on March 12, 2000 during Terra orbit 1243. The three images on the left, from top to bottom, are from the 70-degree forward viewing camera, the vertical-viewing (nadir) camera, and the 70-degree aftward viewing camera. The higher brightness, bluer tinge, and reduced contrast of the oblique views result primarily from scattering of sunlight in the Earth's atmosphere, though some color and brightness variations are also due to differences in surface reflection at the different angles. The longer slant path through the atmosphere at the oblique angles also accentuates the appearance of thin, high-altitude cirrus clouds.

On the right, two areas from the nadir camera image are shown in more detail, along with notations highlighting major geographic features. The south bank of the Red River marks the boundary between Texas and Oklahoma. Traversing brush-covered and grassy plains, rolling hills, and prairies, the Red River and the Canadian River are important resources for farming, ranching, public drinking water, hydroelectric power, and recreation. Both originate in New Mexico and flow eastward, their waters eventually discharging into the Mississippi River.

A smoke plume to the north of the Ouachita Mountains and east of Lake Eufaula is visible in the detailed nadir imagery. The plume is also very obvious at the 70-degree forward view angle, to the right of center and about one-fourth of the way down from the top of the image.

MISR was built and is managed by NASA's Jet Propulsion Laboratory, Pasadena, CA, for NASA's Office of Earth Science, Washington, DC. The Terra satellite is managed by NASA's Goddard Space Flight Center, Greenbelt, MD. JPL is a division of the California Institute of Technology.

Subsidence and thermal history of Southern Oklahoma aulacogen: implications for petroleum exploration  

SciTech Connect

Reconstructed subsidence curves and the thermal history of the Southern Oklahoma aulacogen support the concept of thermally controlled isostatic subsidence for the formation of the basin and indicate the significance of this concept for petroleum exploration. Two mechanisms - initial elastic flexure, followed by detachment and differential subsidence of the aulacogen - are inferred from the subsidence curves. Two methods have been used for reconstruction of the thermal history. A tectonophysics model in combination with a history of basin evolution demonstrates that geothermal gradient and depth-of-burial were dynamic variables during the subsidence stage; maximum paleotemperatures were attained during Sylvan (Late Ordovician) time near the close of subsidence; and most of the Arbuckle Group had been subjected to the temperature conditions of oil formation (the oil liquid window) prior to the possible phase of fluid migration in Sylvan time. The second method, involving reconstruction of the geothermal history on the basis of geothermometry (palynomorph carbonization), suggests: (1) paleotemperatures exerted a significant effect on the level of organic metamorphism in the sedimentary rocks; (2) the geothermal gradient varied during the subsidence stage; (3) paleotemperatures were higher than those predicted by the theoretical model and support the hypothesis of formation of the basin by thermally controlled subsidence, and the application of this concept for petroleum exploration.

Geochemical and Mineralogical Investigation for Carbon Capture and Storage, Within the Arbuckle Aquifer, Kansas  

NASA Astrophysics Data System (ADS)

A class VI permit site under U.S. Department of Energy has been proposed for carbon sequestration in south-central Kansas. In an effort to maintain environmental stability three wells have been drilled to basement rock, two being near the injection site, KGS 1-32 and KGS 1-28, and one being to the western annex, Cutter KGS #1. The western annex site, Cutter, is being utilized as a cross-comparison for mineralogical, geochemical, and structural component to the eastern sites in Wellington. A link will be determined of the continuity of three zones of interest: the Mississippian pay zone (3670'-3700'), a potential baffle zone in the upper Arbuckle (4400'-4550'), and the proposed CO2 injection zone (4900'-5050'). 11 depths within Cutter have been swabbed, and samples taken to investigate the chemistry of the subsurface formation water. The different depths will allow for a quantitative determination of how the brine composition varies with depth, and also provides a baseline for future monitoring. Initial chemical analysis by ICP-OES and HR-ICP-MS show a hyper saline brine (50,000-190,000TDS), dominated by Cl, Na, and Ca ions. pH ranges from 6.4 to 7.5, and total alkalinity from 124 and 378 mg/L of HCO¬3-. One complex, yet intriguing, species is Iron. It could potentially allow for further precipitation of the CO2¬ from the formation of Fe carbonates, such as siderite. Cores and thin sections were taken from a variety of depths ranging from 3681.9' to 5176.9' (Wellington) and 5564.3' to 7540.2' (Cutter). Dominant mineralogy consists of dolomite with varying forms of silicic intrusions, usually in the form of chert nodules with sulfide minerals and argillaceous materials in between. Extensive vugs and microfractures allow for varying porosity within each interval. Pay zone rocks typically display fine-grained cherty dolomite with subhedral to euhedral dolomite rhombs as well as oil stains oriented in parallel blotches. Characteristics such as high porosity and small grain size could potentially lead to quicker reactions with CO2 saturated brine, releasing oil trapped in pore spaces and leading to enhanced oil recovery. The rocks of the baffle zone are characterized by a low porosity dolomitic packstone with increasing abundance of chert, argillaceous materials, and sulfide minerals towards the bottom of the zone. Baffle zone relative impermeability could also allow for improved CO2 reactivity as it would have more time to react with formation minerals. The injection zone is generally composed of dolomite with siliceous nodules that slightly increases with depth. Explicit heterogeneity exists at carbonate-chert boundaries usually occurring in fractures and heavily influencing CO2 to mobilize in a convoluted, potentially lateral fashion. Flow through experiments have been conducted in order to determine reactivity and stability of the overlying cap rocks and baffle zone. Reservoir characterization is determined through geochemical modeling, and will need to be extensively studied in order to properly determine the feasibility for carbon sequestration in Kansas. With the potential for 2.7 billion tones of CO2 to be stored in Kansas, this project could allow Kansas to play a major role in the quest for environmental stability.

Petrography, geochemistry, and 40Ar-39Ar ages of impact melt rocks and breccias from the Ames Impact Structure, Oklahoma: The Nicor Chestnut 18-4 drill core  

NASA Astrophysics Data System (ADS)

The 15-km-diameter Ames structure in northwestern Oklahoma is located 2.75 km below surface in Cambro-Ordovician Arbuckle dolomite, which is overlain by Middle Ordovician Oil Creek Formation shale. The feature is marked by two concentric ring structures, with the inner ring of about 5 km diameter probably representing the collapsed remnant of a structural uplift composed of brecciated Precambrian granite and Arbuckle dolomite. Wells from both the crater rim and the central uplift are oil- and gas-producing, making Ames one of the economically important impact structures. Petrographic, geochemical, and age data were obtained on samples from the Nicor Chestnut 18-4 drill core, off the NW flank of the central uplift. These samples represent the largest and best examples of impact melt breccia obtained so far from the Ames structure. They contain carbonate rocks which, therefore, are derived from the target sequence. The chemical composition of the impact melt breccias is similar to that of target granite, with variable carbonate admixture. Some impact melt rocks are enriched in siderophile elements indicating the possible presence of a meteoritic component. Based on stratigraphic arguments, the age of the crater was estimated at 470 Ma. Previous 40Ar-39Ar dating attempts of impact melt breccias from the Dorothy 1-19 core yielded plateau ages of about 285 Ma, which is in conflict with the stratigraphic age. The new 40Ar-39Ar age data obtained on the melt breccias from the Nicor Chestnut core by UV laser spot analysis, resulted in a range of ages with maxima around 300 Ma. These data could reflect processes related either the regional Nemaha Uplift or resetting due to hot brines active on a midcontinent-wide scale, perhaps in related to the Alleghenian and Ouachita orogenies. The age data indicate an extended burial phase associated with thermal overprint during Late Pennsylvanian-Permian.

Post-Carboniferous tectonics in the Anadarko Basin, Oklahoma: Evidence from side-looking radar imagery  

NASA Astrophysics Data System (ADS)

The Anadarko Basin is a west-northwest east-southeast elongated trough filled with 10+ km of Paleozoic sediments. Most models call for tectonic activity to end in Pennsylvanian time. NASA Shuttle Imaging Radar (SIR-A) has revealed a distinctive and very straight west-northwest striking lineament set extending virtually the entire length of the Anadarko Basin. The lineaments cut across the relatively flat-lying Permian units exposed at the surface. The character of these lineaments is seen most obviously as a tonal variation. Between the lineaments there is a poorly reflecting “gray” zone; better reflectors are located south and particularly north of the lineaments. Analysis of stream drainage and topography suggests that the area between the lineaments is low in the west and high in the east. Major streams, including the Washita and Little Washita rivers, appear to be controlled by the location of the lineaments. Subsurface data indicate that the lineaments may be the updip expression of a buried major fault system, the Mountain View fault. This fault is characterized as southerly dipping; recent COCORP data suggest a shallow dip (30° 40°). Two principal conclusions arise from this analysis: (1) the complex Mountain View fault system appears to extend southeast to join the Reagan, Sulphur, and/or Mill Creek faults of the Arbuckle Mountains, and (2) this fault system has been reactivated in Permian or more recent time. We infer that minor reactivation of the Pennsylvanian faults has resulted in a subdued surficial expression of buried structures that largely control the location of several oil fields in the Anadarko Basin.

Recognition and regional correlation of impact-related {open_quotes}Ames Crater{close_quotes} Arbuckle and Simpson reservoir lithofacies  

SciTech Connect

The concentric structural feature known as the {open_quotes}Ames Hole{close_quotes} or {open_quotes}Ames Crater{close_quotes}, located on the northern shelf of the Anadarko Basin, contains several heterogeneous and uniquely associated hydrocarbon reservoirs, as well as a locally thick (craterfilling) Middle Ordovician (Simpson shale) source rock. Critical diagnostic structural and morphological features, along with petrographic and shock metamorphism evidence, strongly support and impact origin of the structure. Principle crater reservoirs include extremely brecciated, fractured, and faulted, Cambro-Ordovician Arbuckle Group dolomites, Pre-Cambrian granodiorities, devitrified pseudo-pyroclastic (impact melt) rocks, and a rather homogenous, dolomitic ejecta-fallout breccia, which is present along the rim and flanks of the crater. Stratigraphic trapping of hydrocarbons associated with the presence of reservoir-quality ejecta-fallout lithologies unconformably present in the upper portion of the Arbuckle Group, and in reworked, arkosic/dolomitic impact-related lithofacies within the overlying basal Simpson Group, may exist both locally and regionally relative to the {open_quotes}Ames Crater{close_quotes}. Calibration of log-rock characteristics of ejecta-fallout reservoir lithofacies from key crater rim wells provides the basis for field-wide and regional inferences about lithologies, reservoir quality, and related production characteristics. An awareness and understanding of impact-related {open_quotes}Ames Crater{close_quotes} Arbuckle and Simpson lithofacies should lead to refinement of regional Lower and Middle Ordovician stratigraphy, and create renewed exploration strategies for potential stratigraphic traps.

Seismicity of the salt areas of Texas, Louisiana, Oklahoma and Kansas  

SciTech Connect

The results of a seismicity study of the salt deposit areas of Kansas, Oklahoma, Texas and Louisiana are presented. The study was conducted using some of the short-period seismic data recorded on film at the Wichita Mountain Observatory (WMSO), located in southern Oklahoma, during the years 1961 through 1968. Only data recorded on Sundays were analyzed to minimize the confusion of quarry blasts. All major quarries within 400 km of WMSO were located and some of the known blasts were studied for distinguishing characteristics. Inquiries were made to the appropriate state agencies for data to produce a list of historical seismic events which occurred during the 1961 to 1968 period. A salt deposit composite map of the areas was also produced and all historical and previously unreported events, as well as the known quarries, were plotted on this base map.

Poorly characterized critical rock units within the southern Oklahoma Aulacogen  

SciTech Connect

The Southern Oklahoma Aulacogen (SOA) apparently developed during late Proterozoic-early Cambrian rifting of the southern continental margin. This margin appears to be related to the Grenville suture' formed when the Llano terrane was accreted to N.A. The SOA is representative, as well as the best exposed, of a series of penecontemporaneous rifts along the southern and eastern margin of the North American plate. Pronounced Pennsylvanian structural inversion has lifted the igneous basal sections of this rift (the SOA) to shallow crustal levels and exposed parts of it in the Wichita Mountains. Two previously identified but poorly characterized rock units within the SOA, the Tillman Metasedimentary Group and the Navajoe Mountain Basalt/Spilite Group, do not crop out at the surface, having only been recognized from well cuttings. No well-described or well-dated samples exist. The Tillman may be the basement rock which was extended during initial rifting and hosted the igneous infill of the SOA. The Navajoe may represent the earliest phase of magmatism in the SOA. Isotopic dating and geochemistry, and textural/structural relations, of 100--500 m core sections in these two units would go a long way toward clarifying paleotectonic relations and crustal structure in the late Proterozoic. Several drill sites for scientific holes up to 1 km in depth targeted to these enigmatic units can be identified and the rationale for their selection will be presented.

Percentile Distributions of Median Nitrite Plus Nitrate as Nitrogen, Total Nitrogen, and Total Phosphorus Concentrations in Oklahoma Streams, 1973-2001  

USGS Publications Warehouse

Nutrients are one of the primary causes of water-quality impairments in streams, lakes, reservoirs, and estuaries in the United States. The U.S. Environmental Protection Agency has developed regional-based nutrient criteria using ecoregions to protect streams in the United States from impairment. However, nutrient criteria were based on nutrient concentrations measured in large aggregated nutrient ecoregions with little relevance to local environmental conditions in states. The Oklahoma Water Resources Board is using a dichotomous process known as Use Support Assessment Protocols to define nutrient criteria in Oklahoma streams. The Oklahoma Water Resources Board is modifying the Use Support Assessment Protocols to reflect nutrient informa-tion and environmental characteristics relevant to Oklahoma streams, while considering nutrient information grouped by geographic regions based on level III ecoregions and state boundaries. Percentile distributions of median nitrite plus nitrate as nitrogen, total nitrogen, and total phosphorous concentrations were calculated from 563 sites in Oklahoma and 4 sites in Arkansas near the Oklahoma and Arkansas border to facilitate development of nutrient criteria for Oklahoma streams. Sites were grouped into four geographic regions and were categorized into eight stream categories by stream slope and stream order. The 50th percentiles of median nitrite plus nitrate as nitrogen, total nitrogen, and total phosphorus concentrations were greater in the Ozark Highland ecoregion and were less in the Ouachita Mountains ecoregion when compared to other geographic areas used to group sites. The 50th percentiles of median concentrations of nitrite plus nitrate as nitrogen, total nitrogen, and total phosphorus were least in first, second, and third order streams. The 50th percentiles of median nitrite plus nitrate as nitrogen, total nitrogen and total phosphorus concentrations in the Ozark Highland and Ouachita Mountains ecoregions were least in first, second, and third order streams with streams slopes greater than 17 feet per mile. Nitrite plus nitrate as nitrogen and total nitrogen criteria determined by the U.S. Environmental Protection Agency for the Ozark Highland ecoregion were less than the 25th percentiles of median nitrite plus nitrate as nitrogen, total nitrogen, and total phosphorus concentrations in the Ozark Highland ecoregion calculated for this report. Nitrite plus nitrate as nitrogen and total nitrogen criteria developed by the U.S. Environmental Protection Agency for the Ouachita Mountains ecoregion were similar to the 25th percentiles of median nitrite plus nitrate as nitrogen and total nitrogen concentrations in the Ouachita Mountains ecoregion calculated for this report. Nitrate as nitrogen and total phosphorus concentrations currently (2002) used in the Use Support Assessment Protocols for Oklahoma were greater than the 75th percentiles of median nitrite plus nitrate as nitrogen and total phosphorus concentrations calculated for this report.

A transgression-regression event during the deposition of the Upper Cambrian Honey Creek formation in the southern Oklahoma aulacogen  

SciTech Connect

The transgression that inundated the Southern Oklahoma aulacogen during the upper Cambrian enveloped a landscape that consisted of hills of rhyolite up to 350 m in high. Initial deposits on this topography have been interpreted as alluvium. These, together with succeeding tidally-influenced marine siliciclastics form the Reagan Formation. The siliciclastics grains are made up of fragments of local origin (i.e., rhyolite), quartz (derived from a distal source) and authigenic glauconite. The upward passage from the Reagan to the Honeycreek Formation is defined by the addition to the siliciclastics of carbonate detritus in the form of tidally-influenced grainstones, mostly composed of pelmatozoan fragments. The passage from the Honeycreek to the overlying Fort Sill Formation of the Arbuckle Group is marked by the incoming of beds of lime mudstone and the gradual disappearance of grainstones and siliciclastics. Evidence of the existence of rhyolite topography (i.e., an archipelago) can be detected to within 50 m of the top of the Fort Sill. While the overall facies pattern undoubtedly records a widespread transgression, a newly-discovered slightly angular unconformity within the lower part of the Honeycreek is best interpreted as a record of a temporary regression. Three distinctive lithologies are involved in this relationship: the lowest beds are light grey cross-bedded pelmatozoan grainstones with minor amounts of quartz and rhyolite grains. Syntaxial cements at the base of this unit are homogenous under cathode luminescence, while cements near the top display up to 27 zones of reflectance, interpreted as a fluctuating marine-meteoric groundwater imprint. The overlying bed is a red-brown mud-supported limestone that contains abundant angular rhyolite pebbles and a rich trilobite fauna. Some of the pebbles are coated by pelmatozoans.

Integrated geophysical investigations of linkages between Precambrian basement and sedimentary structures in the Ucayali basin, Peru; Fort Worth basin, Texas; and Osage County, Oklahoma  

NASA Astrophysics Data System (ADS)

I conducted integrated geophysical studies within the Fort Worth basin, Texas; Osage County, Oklahoma, and the Ucayali basin, Peru. My studies are directed at understanding the relationships or links between Precambrian basement structures and sedimentary structures using these three areas as case studies. Links between basement structure, hydrocarbon reservoirs, and sedimentary sequences are not a new concept. Such relationships have been documented in the Paradox, Hardeman, Anadarko, Arkoma, Ardmore and Williston basins among others. Structures such as fault zones that can influence the formation of sedimentary basins and mineral deposits are often formed by intraplate tectonism. In order to compare the relationship between the Precambrian basement structures and sedimentary structures, I analyzed series of derivative and filtered maps of aeromagnetic and gravity data, which enhance basement structures, that were integrated with seismic data and seismic attribute data that enhance structures within the sedimentary sections. Other information such as well data and geologic information etc were also integrated. This integrated workflow facilitates the comparison of the links or relationships between the two structures. The results of the Fort Worth basin are presented in Chapter 3. The results of this integrated study show that the sedimentary structures within the study area are mainly related to basement structures because these structures are aligned parallel to anomalies identified on the high-resolution aeromagnetic (HRAM) data. The northeast-southwest and northwest-southeast orientations of sedimentary features are consistently parallel with Precambrian structural fabrics that are associated with structures such as the northeast trending Ouachita orogenic belt and the northwest trending Muenster Arch, which reactivated a late Cambrian/Late Precambrian faults. The knowledge gained in this study will impact oil and gas exploration and development within the study area because, the orientation of the natural and induced fractures can be predicted even if seismic data is limited or unavailable. In Chapter 4, the results of an integrated analysis that includes the use of 3D seismic data, seismic attributes, and derivative maps from potential field data to study the basement, Mississippi Chert and the Arbuckle Group of Osage County, Oklahoma are presented. The workflow employed in this study was effective in studying and identifying polygonal, highly coherent, and high amplitude lineaments that strike northwesterly and northeasterly within these reservoirs. Basement structure lineaments are found to be parallel in orientation with the trend of lineaments seen within the Mississippian Chert and the Arbuckle Group. The northwest-striking lineaments may be related to the late-Paleozoic tectonism that affected both the Precambrian and Paleozoic section of Osage County. Another part of this research investigated the large gravity and magnetic anomalies and their association with the Mid-Continent Rift System (MCRS). Results of this analysis revealed prominent northeast trending anomalies that suggest that the MCRS extends into northern Oklahoma. However, geochronological data for basement rocks suggest that this extension would have to be limited to intrusive bodies that have little or no subcrops. The integrated study conducted in the Ucayali basin of Peru revealed that the northwest-southeast trending lineaments interpreted as Precambrian basement structures are sub-parallel to the late Paleozoic fold and thrust belts that resulted from the shortening associated with the formation of the Andes. These fold and thrust belts are reactivated along the zones of weaknesses that already existed in the Precambrian basement. The east-northeast lineaments are located beneath the Fitzcarrald Arch locate above the buoyant Nazca ridge. I interpret these east-northeast lineaments as part of the Ene Pisco -- Abancay Fitzcarrald tectonic lineaments, which is one of the five tectonic domains in these region. Gravity modeling suggests that t

Oklahoma Center for High Energy Physics (OCHEP)  

SciTech Connect

The DOE EPSCoR implementation grant, with the support from the State of Oklahoma and from the three universities, Oklahoma State University, University of Oklahoma and Langston University, resulted in establishing of the Oklahoma Center for High Energy Physics (OCHEP) in 2004. Currently, OCHEP continues to flourish as a vibrant hub for research in experimental and theoretical particle physics and an educational center in the State of Oklahoma. All goals of the original proposal were successfully accomplished. These include foun- dation of a new experimental particle physics group at OSU, the establishment of a Tier 2 computing facility for the Large Hadron Collider (LHC) and Tevatron data analysis at OU and organization of a vital particle physics research center in Oklahoma based on resources of the three universities. OSU has hired two tenure-track faculty members with initial support from the grant funds. Now both positions are supported through OSU budget. This new HEP Experimental Group at OSU has established itself as a full member of the Fermilab D0 Collaboration and LHC ATLAS Experiment and has secured external funds from the DOE and the NSF. These funds currently support 2 graduate students, 1 postdoctoral fellow, and 1 part-time engineer. The grant initiated creation of a Tier 2 computing facility at OU as part of the Southwest Tier 2 facility, and a permanent Research Scientist was hired at OU to maintain and run the facility. Permanent support for this position has now been provided through the OU university budget. OCHEP represents a successful model of cooperation of several universities, providing the establishment of critical mass of manpower, computing and hardware resources. This led to increasing Oklahoma�¢����s impact in all areas of HEP, theory, experiment, and computation. The Center personnel are involved in cutting edge research in experimental, theoretical, and computational aspects of High Energy Physics with the research areas ranging from the search for new phenomena at the Fermilab Tevatron and the CERN Large Hadron Collider to theoretical modeling, computer simulation, detector development and testing, and physics analysis. OCHEP faculty members participating on the D0 collaboration at the Fermilab Tevatron and on the ATLAS collaboration at the CERN LHC have made major impact on the Standard Model (SM) Higgs boson search, top quark studies, B physics studies, and measurements of Quantum Chromodynamics (QCD) phenomena. The OCHEP Grid computing facility consists of a large computer cluster which is playing a major role in data analysis and Monte Carlo productions for both the D0 and ATLAS experiments. Theoretical efforts are devoted to new ideas in Higgs bosons physics, extra dimensions, neutrino masses and oscillations, Grand Unified Theories, supersymmetric models, dark matter, and nonperturbative quantum field theory. Theory members are making major contributions to the understanding of phenomena being explored at the Tevatron and the LHC. They have proposed new models for Higgs bosons, and have suggested new signals for extra dimensions, and for the search of supersymmetric particles. During the seven year period when OCHEP was partially funded through the DOE EPSCoR implementation grant, OCHEP members published over 500 refereed journal articles and made over 200 invited presentations at major conferences. The Center is also involved in education and outreach activities by offering summer research programs for high school teachers and college students, and organizing summer workshops for high school teachers, sometimes coordinating with the Quarknet programs at OSU and OU. The details of the Center can be found in http://ochep.phy.okstate.edu.

Oklahoma administrators' perceptions of applied science  

NASA Astrophysics Data System (ADS)

Scope and method of study. The purpose of this study was to assess the perceptions of Oklahoma Public School Superintendents when applied science courses such as Applied Biology/Chemistry and Applied Physics (Principles of Technology) are compared to traditional science courses such as Biology, Chemistry, and Physics. The study was conducted with a population of 69 Oklahoma comprehensive school superintendents who were under contract during the 1997/98 school year. Each participant was employed by a school district that offered either Applied Biology/Chemistry, Applied Physics (also known as Principles of Technology) or both. All participants completed an 18-question telephone survey. Combined means and percentages of participants responses to the survey were recorded to draw conclusions about the study. Findings and conclusions. Superintendents perceive teachers and students as having good acceptance of applied science courses. Superintendents believe students think of applied science courses as excellent hands-on science, and teachers think of them as acceptable alternative science. Superintendents are somewhat satisfied with applied science courses. They believe it makes no difference if a student is college bound, non-college bound, more motivated or less motivated as to whom benefits from applied science courses. Superintendents feel there is no difference in applied science courses and traditional science courses when teaching science concepts of "PASS Skills," or preparing students for college or work. They perceive the cost of applied science courses to be somewhat greater than traditional science courses. They also think additional training for applied science teachers should be in the form of a seminar. Superintendents feel full credit toward high school graduation and college entrance requirements should be given to the students of applied science courses. Superintendents believe there is no difference as to which course, applied science or traditional science, that utilize facilities better. They believe applied science courses should be offered as an alternative science class and that they have a good future in the Oklahoma educational system.

Chemical analyses of surface waters in Oklahoma, September - December 1944  

USGS Publications Warehouse

A preliminary survey of the industrial quality of surface waters in Oklahoma was started in August, 1944, by the U.S. Geological Survey in cooperation with the Oklahoma Resources and Planning Board, with the Oklahoma A. & M. College, Engineering Experiment Station and Department of Chemistry. From September to December, 1944, three hundred and fifteen samples were obtained at eighty-four points where gages are maintained for measurement of discharge. Daily samples were collected at six stations, namely: Illinois River near Gore, Oklahoma Cimarron River near Oilton, Oklahoma Canadian River near Whitefield, Oklahoma Washita River near Durwood, Oklahoma Red River near Gainesville, Texas Red River at Denison Dam, Texas Sport samples were collected at the remainder of the stations. The analyses of the spot samples were made largely in a laboratory provided by the Oklahoma A. & M. College, under the supervision of Dr. O.M. Smith, Head, Department of Chemistry; Dr. S.R. Wood, Associate Professor of Chemistry; and W.W. Hastings, U.S. Geological Survey. The daily samples were analyzed in the water resources laboratory of the Geological Survey at Austin, Texas. These data have been summarized in a report to the Oklahoma Planning and Resources Board prepared by the U.S. Geological Survey, March 1, 1945. The streams of Oklahoma are classified into two major drainage basins: the Arkansas River and the Red River and their tributaries. The attached analyses are arranged in geographical order for their respective drainage basins, with records listed in downstream order for stations on the main stem first, followed by the analyses for the tributaries. When available, the mean daily discharge is given for the analyses. (available as photostat copy only)

Mass casualties in the Oklahoma City bombing.  

PubMed

The Alfred P. Murrah Federal Building in Oklahoma City was partially destroyed by a terrorist bomb on April 19, 1995. Injuries were sustained by 759 people, 168 of whom died. Fatalities occurred primarily among victims in the collapse zone of the federal building. Only 83 survivors required hospitalization. Twenty-two surviving victims sustained multiple fractures. Most victims arrived at local emergency departments by private vehicle within 2 hours. More severely injured survivors were transported by ambulance. The closer receiving hospitals used emergency department facilities and minor treatment areas. Few survivors were extricated from the bombing site more than 3 hours after the detonation. Mass casualty plans must provide for improved communications, diversion and retriage from facilities nearest the disaster site, and effective coordination of community and hospital resources.

Seismogram offers insight into Oklahoma City bombing  

NASA Astrophysics Data System (ADS)

The terrorist bombing of the Alfred P. Murrah Federal Building in Oklahoma City on April 19, 1995, generated seismic waves that were recorded on two permanent seismographs about 7 and 26 km away from the bombing. The seismogram recorded at 26 km shows two low-frequency wave trains, discrete sets of oscillatory signals, that begin about 10 s apart. Public release of this record prompted speculation that each wave train was caused by a different energy source. On May 23, 1995, the U.S. Geological Survey monitored the demolition of the bomb-ravaged Federal Building with portable seismographs (Figure 1). Two wave trains were picked up again. The recordings indicate that the wave trains during both the bombing and demolition represent seismic waves traveling at different velocities. We conclude that the two wave trains recorded during the bombing are consistent with a single impulsive energy source.

Mountains Majesty: Ecosystems of the Rocky Mountains  

NSDL National Science Digital Library

Traveling from the East, one can see the towering snow-covered peaks of the Rocky Mountains long before reaching foothills. But to fully appreciate these mountains, one must venture into them and experience up close the colorful bursts of summer wildflowers, the glittering leaves of the quaking aspen, the cold clear alpine streams and lakes, and the distinctive sweet scent of the ponderosa pine. Scientists from the Bureau of Land Management provide an in-depth look at the management issues and diversity of plants, animals, and habitats of the Rocky Mountains.

Seismic exploration of Ouachita frontal fairway, southeastern Oklahoma  

SciTech Connect

The Ouachita frontal fairway has been the site of considerable recent exploration and significant discoveries. Targets include Spiro and Wapanucka reservoirs on thrusted structures, and deeper Arbuckle carbonates on fault-bounded blocks. Because of the tectonic complexity of the area, favorable trends and prospects are defined using modern seismic data. High quality seismic data requires careful acquisition and processing. Acquisition should aim to minimize skips, to maintain a close group interval, and to record data on far offsets. In processing, migration velocities must be selected carefully because they affect apparent size of a structure. Interpretation should be based on simultaneous examination of migrated and unmigrated sections. Sections exhibiting sideswipe should be interpreted with caution. Recently acquired seismic data illustrates the structural style and exploration challenges of the Ouachita frontal fairway.

Gravity, magnetics point to volcanic origin for Oklahoma's Ames anomaly  

SciTech Connect

This paper reports that a recent publication of high production volumes of Arbuckle oil and gas at Ames in Major County, Okla., favors an astrobleme as the cause of structural deformation. The feature expresses a distinct circular geologic depression on the top of the Sylvan shale in Townships 20-21 North, Ranges 9-10 West. Consolidated Geophysical Surveys presents gravity and vertical intensity magnetic data in support of a volcanic origin. Three stages of volcanic activity are projected. CGS' interest in the cause of the Ames anomaly was founded initially in its study of the reported Red Wing Creek (North Dakota) astrobleme during the company's extensive gravity and magnetic exploration in the Williston basin in the 1980s. The regional gravity and magnetic gradients over the Red Wing Creek anomaly bear no resemblance to the Ames feature.

Mountain weather and climate  

SciTech Connect

Mountain environments are reaching the world environmental agenda of concern. The first edition of this book provided a well organized set of principles on how weather and climate processes operate in mountain environments; it was and remains the major reference on the subject. This second edition remains in the original format but adds new material, including updates and increased bibliography and stressing the importance of the temporal dimension of mountain climates and the potential sensitivity of these environments to global change processes.

The Meers Fault in Southern Oklahoma: Holocene Movements on a Fault with Pennsylvanian and Cambrian Linages  

NASA Astrophysics Data System (ADS)

The Meers fault and subparallel fault strands in southern Oklahoma is the southernmost element of the complex and massive (>10 km of throw) frontal fault zone that forms the boundary between the Anadarko basin, which is the deepest intra-continental basin in the United States, and the uplifted Cambrian igneous rocks of the Wichita Mountains. The Wichita uplift is evidence of extraordinary Pennsylvanian intra-plate deformation along the trend of the Southern Oklahoma aulacogen, which is a classic example of a failed and massively inverted rift. The Meers Fault is the best-documented Holocene fault scarp east of Colorado and probably represents reactivation of a Pennsylvanian oblique thrust that in turn is likely to be an inverted Cambrian normal fault. The magnitude of these structures is shown on images from 3-D industry seismic reflection data ~25 km northwest of the northwestern mapped extent of the Meers fault that indicate the Pennsylvanian structure, or a northern strand of it, has a reverse throw of ~6km at depth. The fault displays a conspicuous and continuous scarp that is at least 25 km long and is evident in air photos and 1:100,000 scale geologic mapping, but this feature is not well mapped in detail beyond the area of trenching studies conducted in the 1980's. In the Holocene, 3-5 m of vertical surface displacement has been documented and left-lateral strike slip displacement on the fault is 2-3 times greater than the vertical displacement. During this movement, Quaternary soils along the fault were folded and ruptured, and the scarp has dammed small gullies where fine-grained alluvium has collected and has been used in the dating efforts. The most recent movement occurred (1100-1300 y ago) with a variety of earlier events having been proposed. As such, this fault represents one of the highest potential seismic hazards in the central/eastern United States.

A proposed streamflow data program for Oklahoma  

USGS Publications Warehouse

An evaluation of the streamflow data available in Oklahoma has been made to provide guidelines for planning future data-collection programs. The basic steps in the evaluation procedure were (1) definition of the long-terms goals of the streamflow-data program in quantitative form, (2) examination and analysis of streamflow data to determine which goals have been met, and (3) consideration of alternate programs and techniques to meet the remaining goals. The study defines the individual relation between certain statistical streamflow characteristics and selected basin parameters. This relation is a multiple regression equation that could be used on a statewide basis to compute a selected natural-flow characteristic at any site on a stream. The study shows that several streamflow characteristics can be estimated within an accuracy equivalent to 10 years of record by use of a regression related to at least three climatic or basin parameters for any basin of 50 square miles or more. The study indicates that significant changes in the scope and character of the data-collection program would enhance the possibility of attaining the remaining goals. A streamflow-data program based on the guidelines developed in this study is proposed for the future.

Galileo's Moon Mountain  

NSDL National Science Digital Library

The Galileo's Moon Mountain Model illustrates the method used by Galileo to measure the height of a mountain on the Moon. Using his improved telescope design, Galileo was able to see spots of light in the otherwise dark potion of the Moon. He interpreted these spots as mountain peaks which caught the rays of the sun even though the sun did not illuminate the Moon's surface at the base of the mountain. He measured the distance of the bright spot from the terminator (the line separating the lit and unlit portions of the Moon) as a fraction of the Moon's radius. Then he was able to use a geometrical argument to determine the height of the mountain as a fraction of the Moon's radius. Galileo knew that the Moon's radius was approximately 1600 km (he didn't use those units, of course), which allowed him to determine the absolute height of the mountain. (Note that the modern value for the Moon's radius is about 1740 km.) One window shows the view from above the North pole of the Moon. The mountain appears near the bottom of this window. A ray of sunlight which just grazes the Moon's surface at the terminator is shown. Controls allow the user to adjust the angle of sunlight (thus altering the Moon's phase) and the height of the mountain. The other window shows the view from Earth. When sunlight strikes the top of the mountain a bright spot becomes visible in the dark area of the Moon. Likewise, when the mountain is in the bright region it casts a shadow. The distance across the Moon's face from terminator to mountain in shown.

Structural evolution of the Ardmore basin, Oklahoma, U.S.A.: Progressive deformation in the foreland of the Ouachita collision  

NASA Astrophysics Data System (ADS)

Synthesis of oil field studies, seismic reflection data, and surface geology has resulted in a reconstruction of the Pennsylvanian evolution of the structural style of fault systems bordering and within the Ardmore Basin in south central Oklahoma. Faults bounding the margins of the basin were part of a broader left-lateral shear belt that affected southern Oklahoma during the early Pennsylvanian. The mid-Pennsylvanian and later zone of deformation contracted in southern Oklahoma to concentrate on the Washita Valley-Eola Robberson fault systems along the northern edge of the basin, and on the Criner Uplift-Healdton-Stephens County fault systems along the southern and western side of the basin. Deformation on the floor of the basin was amplified, with left-lateral strike-slip faults slicing the basin into a system of rhombohedral blocks. Deformation continued at least into Virgil time (late Pennsylvanian). A two-dimensional displacement field derived for the middle to late Pennsylvanian deformation reveals that a strong component of transpression affected both the basin-bounding faults and, by reason of the geometry of their connections to the west, the Wichita Mountain front as well. Broadly spread left-lateral shear evolved into crustal scale transpression during the Pennsylvanian Period. That progressive contraction of deformation and the change in style correlate with mid-Pennsylvanian approach and passage of the Ouachita collision along the Ouachita embayment (Thomas, 1983) on the southern margin of the North American craton. Inasmuch as the Ardmore Basin was located at the sharp internal corner of the embay ment, the coincidence suggests that the style of evolution records (1) early far-field influence of the approaching Ouachita collision during early Pennsylvanian, (2) passage of the suture during mid-Pennsylvanian, and (3) concentration of foreland deformation at the corner of the embayment as the Arkoma and Fort Worth flexural basins evolved to the south and east during late Pennsylvanian.

Tight Oklahoma gas sands remain an attractive play  

SciTech Connect

The Cherokee tight gas sands of Oklahoma remain an attractive play because of improvements in drilling and completion practices and actions by the Oklahoma Corporation Commission (OCC) that allow separate allowables for new wells. The expired federal tax credits for tight gas wells have not been the only reason for increased activity. Since decontrol of most regulated gas pricing and since 1986, the number of wells drilled and gas production per well have been increasing in the cherokee area while overall drilling in Oklahoma has decreased. These conclusions are based on wells as categorized by permit date and not by the spud, completion, or first production date. A few wells outside but adjacent to the Cherokee area may have been included, although, their impact on the conclusions is considered nominal. The paper discusses the tight gas credit, proration units, the concept of separate allowables, costs, completion efficiency, and the economic outlook for this area.

Characteristics of successful aviation leaders of Oklahoma  

NASA Astrophysics Data System (ADS)

Scope and method of study. The purpose of the study was to examine the personal traits, skills, practices, behaviors, background, academic, and career success patterns of selected aviation leaders in Oklahoma. A purposive sample of 18 leaders who had achieved a top-ranked position of aviation leadership in an organization or a position of influence in the community was selected for interview. The leaders chosen for interview came from a variety of aviation organizations including government, academia, military, corporate aviation, and air carrier leadership as well as community leadership (specifically those aviation personnel who were engaged in a political or civic leadership role). Findings and conclusions. This study identified no common career choices, educational, family, or other background factors exclusively responsible for leadership success of all of the participants. Some of the more significant findings were that a high percentage of the leaders held undergraduate and advanced degrees; however, success had been achieved by some who had little or no college education. Aviation technical experience was not a prerequisite for aviation leadership success in that a significant number of the participants held no airman rating and some had entered positions of aviation leadership from non-aviation related careers. All had received some positive learning experience from their family background even those backgrounds which were less than desirable. All of the participants had been involved in volunteer civic or humanitarian leadership roles, and all had received numerous honors. The most frequently identified value expressed by the leaders was honesty; the predominant management style was participative with a strong backup style for directing, the most important skills were communication and listening skills, and the most frequently mentioned characteristics of success were honesty, credibility, vision, high standards, love for aviation and fiscal responsibility. The most frequently identified curriculum need across all aviation disciplines was that of communication skills.

Large-scale planting of North Carolina loblolly pine in Arkansas and Oklahoma: a case of gain versus risk  

SciTech Connect

Plantations established using 6 provenances and aged 5, 8, 9, or 25 years were measured in 1981. Soil moisture deficits (SMDs) were calculated for each test area using 1980 data. The fastest growing provenances were from E. of the Mississippi River, in particular those from coastal North Carolina and near the Gulf coast of Louisiana. There were only small differences in cold and drought resistance. No appreciable mortality was observed for stands with SMD of less than 32 cm. At higher SMDs, mortality and damage to needle tissues were greater, and always higher for North Carolina than for Arkansas or Oklahoma provenances. This indicates that coastal North Carolina pine, which evolved on poorly drained and deep soils, may experience greater mortality than the local sources under extreme drought, especially on the excessively drained and shallow soils in the Ouachita Mountains.

The U.S. Geological Survey, in cooperation with the city of Oklahoma City, has collected water-quality samples at the North Canadian River near Harrah, Oklahoma (the Harrah station), since 1968, and the North Canadian River at Britton Road at Oklahoma City, Oklahoma (the Britton Road station), since 1988. The North Canadian municipal wastewater-treatment plant, managed by the city of Oklahoma City, is the largest wastewater-treatment plant in the North Canadian River Basin and discharges effluent between the Britton Road and Harrah stations. Water-quality constituent concentrations were summarized, and trends in concentrations and frequencies of detection of selected constituents with time were evaluated to determine if changes in land cover, streamflow, and other potential sources of constituents in water had significant effects on water quality in the North Canadian River downstream from Oklahoma City.

Public health assessment for Oklahoma Refining Company, Cyril, Caddo County, Oklahoma, Region 6. Cerclis No. OKD091598870. Final report  

SciTech Connect

The Oklahoma Refining Company site, near the town of Cyril, Caddo County, Oklahoma, is approximately 160 acres. Contaminants associated with the site include volatile organic compounds, semi-volatile compounds, heavy metals, polycyclic aromatic hydrocarbons (PAHs), and petroleum hydrocarbons. Heavy metals and PAHs are the primary contaminants at levels of health concern. During refinery operations, ambient air was likely to have been and could be a significant exposure pathway for on-site workers and off-site residents. Residents swimming in Gladys Creek downstream of the ORC site during refinery operations were likely to have been exposed to contaminants in surface water and sediment. The Agency for Toxic Substances and Disease Registry (ATSDR) has concluded that the Oklahoma Refining Company site was a public health hazard during its past operation based on probable exposure during the release of wastes from the oil refinery process.

Shaping the Rwenzori Mountains  

NASA Astrophysics Data System (ADS)

The Rwenzori Mountains are a high alpine mountain chain, about 40x80 km in size, just north of the equator in the western branch of the East African Rift System in Africa. The central part of the mountain chain is located in Uganda, and the highest peak, the Margherita Peak with 5119 m, lies on the border to the Democratic Republic of Kongo. Topography is very pronounced, with steeply incised valleys and clear glacial landforms in the upper part of the mountain chain. The Rwenzori Mountains are an unusually high mountain chain located in the extensional setting of the East African Rift System, and the huge elevation poses a challenging problem for geodynamists to explain. We use the numerical model Ultima Thule to simulate the evolution of the Rwenzori Mountain chain over the period of around 800,000 years with a temperature variation derived from ice-core data. Processes considered are ice-sheet evolution, hillslope diffusion, fluvial incision, glacial abrasion, surface deformation, and tectonic uplift. With a set of numerical experiments, we estimate the temperature drop between the present day and the last glacial maximum needed to glaciate to high parts of the Rwenzori in accordance to field data. We then provide estimates on the morphological processes decreasing the relief, and the amount of tectonic uplift needed to counter-act the decrease in topographic height.

Early petroleum exploration, Rocky Mountain region, USA  

SciTech Connect

Historically, geology exposed on the flanks of Rocky Mountain uplifts has given unique opportunities to integrate surface and subsurface data to understand the petroleum geology of the intermontane basins. Exploration evolved from drilling near seeps to mapping of surface anticlines, to use of geophysics and subsurface data acquired by drilling. Oil seeps were first recorded by explorers in Wyoming in 1832 (Dallas dome, Wind River basin) and 1847 (Absaroka thrust, southwest area). Oil skimmed from springs was used for medicinal purposes and sold for wagon lubrication. The first commercial well was drilled in 1862 by an oil seep 9 mi north of Florence, Colorado. Subsequent drilling led to the discovery of the Florence field which has now produced more than 15,000,000 barrels of oil. Production is from fractured Cretaceous shale in a tilted graben with a fault trap on the updip side. Early fields were geologically diverse and reports describing the accumulations developed concepts that guided exploration in the region. The following fields illustrate the wide range of trapping conditions. (1) Faults and fractures on homoclinal dip: Florence-Oil Creek area (1862) and Boulder (1901), Colorado; Uinta basin, Utah. (2) Closed anticline: Dallas dome (1884) and Salt Creek (1908), Wyoming; Rangely (1902), Colorado. (3) Stratigraphic change on anticlinal plunge or regional dip: Moorcroft (1888) and Shannon (1889), Wyoming. (4) Syncline: Mexican Hat (1907), Utah; Blanco gas field (1926), New Mexico. (5) Unconformity: Kevin-Sunburst (1922), Montana. Techniques and ideas developed in areas peripheral to the Rocky Mountains also influence exploration in the overall region, especially Kansas, Oklahoma, and Canada.

University of Oklahoma - High Energy Physics  

SciTech Connect

The High Energy Physics program at the University of Oklahoma, Pat Skubic, Principal Investigator, is attempting to understand nature at the deepest level using the most advanced experimental and theoretical tools. The four experimental faculty, Brad Abbott, Phil Gutierrez, Pat Skubic, and Mike Strauss, together with post-doctoral associates and graduate students, are finishing their work as part of the D0 collaboration at Fermilab, and increasingly focusing their investigations at the Large Hadron Collidor (LHC) as part of the ATLAS Collaboration. Work at the LHC has become even more exciting with the recent discovery by ATLAS and the other collaboration, CMS, of the long-sought Higgs boson, which plays a key role in generating masses for the elementary constituents of matter. Work of the OUHEP group has been in the three areas of hardware, software, and analysis. Now that the Higgs boson has been discovered, completing the Standard Model of fundamental physics, new efforts will focus on finding hints of physics beyond the standard model, such as supersymmetry. The OUHEP theory group (Kim Milton, PI) also consists of four faculty members, Howie Baer, Chung Kao, Kim Milton, and Yun Wang, and associated students and postdocs. They are involved in understanding fundamental issues in formulating theories of the microworld, and in proposing models that carry us past the Standard Model, which is an incomplete description of nature. They therefore work in close concert with their experimental colleagues. One also can study fundamental physics by looking at the large scale structure of the universe; in particular the ``dark energy'' that seems to be causing the universe to expand at an accelerating rate, effectively makes up about 3/4 of the energy in the universe, and yet is totally unidentified. Dark energy and dark matter, which together account for nearly all of the energy in the universe, are an important probe of fundamental physics at the very shortest distances, or at the very highest energies. The outcomes of the group's combined experimental and theoretical research will be an improved understanding of nature, at the highest energies reachable, from which applications to technological innovation will surely result, as they always have from such studies in the past.

Mountains of Fractals  

NSDL National Science Digital Library

The "Mountains of Fractals" article in the Math DL develops algorithms to produce coastlines and mountains in two dimensions by adapting mathematical ideas related to the construction of such fractals as Koch's curve. EJS is used to create a hands-on activity that allows a reader to create a coastline with a rubberband, six-sided die, and thumb tacks. Java applications allow for exploration of these algorithms and the influence of their associated parameters. After discussing 2D fractal mountains, this article extends the 2D algorithm to produce 3D mountains. Finally, mathematical issues in random number generation are discussed. More specifically, linear congruential generators are considered and shown to be suitable as a random number generator for the 3D fractal landscape algorithm. The use of fractal landscapes in movies is also discussed.

Environmental and hydrologic setting of the Ozark Plateaus study unit, Arkansas, Kansas, Missouri, and Oklahoma  

USGS Publications Warehouse

The environmental and hydrologic setting of the Ozark Plateaus National Water-Quality Assessment (NAWQA) study unit and the factors that affect water quality are described in this report. The primary natural and cultural features that affect water- quality characteristics and the potential for future water-quality problems are described. These environmental features include climate, physio- graphy, geology, soils, population, land use, water use, and surface- and ground-water flow systems. The study-unit area is approximately 47,600 square miles and includes most of the Ozark Plateaus Province and parts of the adjacent Osage Plains and Mississippi Alluvial Plain in parts of Arkansas, Kansas, Missouri, and Oklahoma. The geology is characterized by basement igneous rocks overlain by a thick sequence of dolomites, limestones, sandstones, and shales of Paleozoic age. Land use in the study unit is predominantly pasture and forest in the southeastern part, and pasture and cropland in the northwestern part. All or part of the White, Neosho-lllinois, Osage, Gasconade, Meramec, St. Francis, and Black River Basins are within the study unit. Streams in the Boston Mountains contain the least mineralized water, and those in the Osage Plains contain the most mineralized water. The study unit contains eight hydrogeologic units including three major aquifers--the Springfield Plateau, Ozark, and St. Francois aquifers. Streams and aquifers in the study unit generally contain calcium or calcium-magnesium bicarbonate waters. Ground- and surface-water interactions are greatest in the Salem and Springfield Plateaus and least in the Boston Mountains and Osage Plains. Geology, land use, and population probably are the most important environmental factors that affect water quality.

YUCCA MOUNTAIN SITE DESCRIPTION  

SciTech Connect

The ''Yucca Mountain Site Description'' summarizes, in a single document, the current state of knowledge and understanding of the natural system at Yucca Mountain. It describes the geology; geochemistry; past, present, and projected future climate; regional hydrologic system; and flow and transport within the unsaturated and saturated zones at the site. In addition, it discusses factors affecting radionuclide transport, the effect of thermal loading on the natural system, and tectonic hazards. The ''Yucca Mountain Site Description'' is broad in nature. It summarizes investigations carried out as part of the Yucca Mountain Project since 1988, but it also includes work done at the site in earlier years, as well as studies performed by others. The document has been prepared under the Office of Civilian Radioactive Waste Management quality assurance program for the Yucca Mountain Project. Yucca Mountain is located in Nye County in southern Nevada. The site lies in the north-central part of the Basin and Range physiographic province, within the northernmost subprovince commonly referred to as the Great Basin. The basin and range physiography reflects the extensional tectonic regime that has affected the region during the middle and late Cenozoic Era. Yucca Mountain was initially selected for characterization, in part, because of its thick unsaturated zone, its arid to semiarid climate, and the existence of a rock type that would support excavation of stable openings. In 1987, the United States Congress directed that Yucca Mountain be the only site characterized to evaluate its suitability for development of a geologic repository for high-level radioactive waste and spent nuclear fuel.

Comparative analysis of wind energy production in Oklahoma  

NASA Astrophysics Data System (ADS)

Scope and method of study. In the last decades humanity has realized the necessity of developing alternative energy sources for its efficient economic development and simple survival in the future. During the last 30 years major improvements were made in renewable energy technologies and they started to become competitive with traditional energy sources (fossil fuels), especially with consideration of external costs. Among the renewable energy sources, wind energy is one of the cheapest and fastest growing nowadays. Oklahoma is a very promising site for wind energy development considering its excellent wind resources. Developing wind energy can allow not only electricity production for in-state consumption, but also exporting to other states. The development of wind energy could encourage economic growth with very few adverse impacts on the environment. However, traditional energy sources are still the cheapest and, thus, the introduction of the wind energy in Oklahoma should be critically analyzed from economic, ecological and social points of view. The goal of this study is to conduct analysis of wind energy electricity production in Oklahoma on the four main stages: (1) Investment Analysis from Private Perspective: Calculate present value net benefits for wind energy and traditional energy (natural gas), make sure that both of them are positive. (2) Investment Analysis from Social Perspective: Evaluate present value net private benefits (PVNPB) and present value net social benefit from both projects (PVNSB). (3) Government Subsidy Analysis: recognize the necessity of the subsidies and evaluate the amount of subsidies if any. (4) Investment Analysis from a Geographic Perspective: determine economic feasibility of wind power generation for 77 Oklahoma counties. Findings and conclusions. The final output of the study is the recommendations concerning wind energy development in Oklahoma with consideration of economic efficiency, ecological and social impacts. Study not only analyze possibilities for wind energy development in the state, but make recommendations on the county by county basis with consideration of wind power density, land cost, property tax and infrastructure development in each county.

Diurnal cycle of the Oklahoma City urban heat island  

NASA Astrophysics Data System (ADS)

Between the dates of 28 June and 31 July 2003, the Joint Urban 2003 (JU2003) field project was conducted in Oklahoma City and was the largest urban dispersion experiment ever in North America. Because the focus of JU2003 was on atmospheric processes within the urban environment, an extremely dense network of instrumentation was deployed in and around the central business district (CBD) both prior to and during the field experiment. Among the variables collected were high-resolution observations of air temperature from various instrument sources. Additional observations of air temperature were also collected at Oklahoma Mesonet stations in the rural areas surrounding Oklahoma City. Using an index value, the diurnal cycle of the urban heat island (UHI) for Oklahoma City, with respect to the surrounding rural terrain, was quantified. The results revealed a consistent mean nocturnal UHI greater than 1.5°C at both 2 and 9 m. However, observations at 2 m during JU2003 revealed a significant urban "cool" island during the convective portion of the day. The mean variability of temperature within the urban core of Oklahoma City increased significantly after sunrise, increased to a maximum near solar noon, and decreased following sunset. These results were inconsistent with the rural observations wherein the variability among sites was maximized during the nocturnal period. Finally, the vertical temperature gradient between 2 and 9 m demonstrated a clear and strong diurnal trend at the rural locations, whereas observations from the urban environment were nearly isothermal and consistent with near-neutral conditions throughout JU2003.

Estimated flood peak discharges on Twin, Brock, and Lightning creeks, Southwest Oklahoma City, Oklahoma, May 8, 1993  

USGS Publications Warehouse

The flash flood in southwestern Oklahoma City, Oklahoma, May 8, 1993, was the result of an intense 3-hour rainfall on saturated ground or impervious surfaces. The total precipitation of 5.28 inches was close to the 3-hour, 100-year frequency and produced extensive flooding. The most serious flooding was on Twin, Brock, and Lightning Creeks. Four people died in this flood. Over 1,900 structures were damaged along the 3 creeks. There were about $3 million in damages to Oklahoma City public facilities, the majority of which were in the three basins. A study was conducted to determine the magnitude of the May 8, 1993, flood peak discharge in these three creeks in southwestern Oklahoma City and compare these peaks with published flood estimates. Flood peak-discharge estimates for these creeks were determined at 11 study sites using a step-backwater analysis to match the flood water-surface profiles defined by high-water marks. The unit discharges during peak runoff ranged from 881 cubic feet per second per square mile for Lightning Creek at SW 44th Street to 3,570 cubic feet per second per square mile for Brock Creek at SW 59th Street. The ratios of the 1993 flood peak discharges to the Federal Emergency Management Agency 100-year flood peak discharges ranged from 1.25 to 3.29. The water-surface elevations ranged from 0.2 foot to 5.9 feet above the Federal Emergency Management Agency 500-year flood water-surface elevations. The very large flood peaks in these 3 small urban basins were the result of very intense rainfall in a short period of time, close to 100 percent runoff due to ground surfaces being essentially impervious, and the city streets acting as efficient conveyances to the main channels. The unit discharges compare in magnitude to other extraordinary Oklahoma urban floods.

The High Plains is a major agricultural area, supported primarily by water from the High Plains aquifer, which is used to irrigate wheat and corn and to raise cattle and swine. The U.S. Geological Survey (USGS) and the Oklahoma Water Resources Board (OWRB) began a study of the High Plains aquifer in 1996. One purpose of the study was to develop a ground-water flow model that the OWRB could use to allocate the amount of water withdrawn from the a aquifer. The study area in Oklahoma covers all or parts of Beaver, Cimarron, Dewey, Ellis, Harper, Texas, and Woodward Counties. To provide appropriate hydrologic boundaries for the ground-water flow model, the study area was expanded to include parts of Colorado, Kansas, New Mexico, and Texas.

Karst in Permian evaporite rocks of western Oklahoma  

SciTech Connect

Bedded evaporites (gypsum and salt) of Permian age have been dissolved naturally by ground water to form a major evaporite-karst region in western Oklahoma. The Blaine Formation and associated evaporites comprise 100--800 ft of strata that dip gently into broad, structural basins. Outcropping gypsum, dolomite, and red-bed shales of the Blaine display typical karstic features, such as sinkholes, caves, disappearing streams, and springs. Large caves are developed in gypsum beds 10--30 ft thick at several places, and a major gypsum/dolomite karst aquifer provides irrigation water to a large region in southwestern Oklahoma, where salt layers above and below the Blaine Formation have been partly dissolved at depths of 30--800 ft below the land surface. Salt dissolution causes development of brine-filled cavities, into which overlying strata collapse, and the brine eventually is emitted at the land surface in large salt plains.

Variable seismic response to fluid injection in central Oklahoma  

NASA Astrophysics Data System (ADS)

Seismicity in Oklahoma since 2009 has been concentrated in the central portion of the state, in the areas of Jones, Prague, and Luther. These three regions account for ~75% of earthquakes in the 2009-2013 Oklahoma Geological Survey catalog. A swarm in the Jones region began in late 2008, with a maximum magnitude of 4.0, and activity continuing to the present. After relocation, the initially diffuse earthquakes in the Jones swarm delineate multiple subparallel faults. The Wilzetta fault zone ruptured in the Prague region in 2010 and again in 2011, with magnitudes up to Mw5.7, and the Luther region experienced two earthquakes of M4.4 and M4.2, with related aftershocks, in 2013. The earthquakes near Prague have previously been linked to wastewater disposal; here we show that the earthquakes near Jones and Luther may also be induced by deep disposal based on the upsurge in seismicity in central Oklahoma coupled with local relationships to pumping and reservoir structure. The timing of each sequence with respect to injection and the distribution of seismic activity differs, highlighting the variability in seismic response to fluid injection related to local permeability structure.

Red Fork sandstone of Oklahoma: depositional history and reservoir distribution  

SciTech Connect

The Middle Pennsylvanian Red Fork sandstone formed as a result of progradation across eastern Kansas and most of Oklahoma. The Red Fork is one of several transgressive-regressive sequences (cyclothems) developed within the Desmoinesian Cherokee Group. Sea level changes, together with varying subsidence, were dominant factors controlling the general stratigraphic (correlative) characteristics of the Red Fork interval. Progradation was episodic, with sand deposition in the more active part of the basin during lower sea level stands and valley-fill deposition in the more stable areas during sea level rises. A map of Red Fork sand trends reveals an alluvial-deltaic complex covering most of Oklahoma. The Red Fork consists primarily of alluvial-valley and plain (fluvial) bodies in the northernmost part of northeastern Oklahoma, alluvial-deltaic bodies in most of the remaining parts of the shelf area, and off-shelf submarine-fan and slope basinal-floor complexes within the deeper part of the Anadarko basin. Determination of reservoir trend and genesis requires integration of rock and log data. Logs need to be calibrated to cores in order to estimate depositional environments accurately and to make a reasonable assessment of diagenetic overprints. Much of the oil and gas has been trapped in stratigraphic traps, and a significant amount of oil is in channel sandstones with trends at high angles to the structural grain. In some areas, secondary clay, in particular chloritic clay, has resulted in microporosity, high water saturation, and correspondingly low resistivities in oil reserves.

Melting Mountain Glaciers  

NSDL National Science Digital Library

The world's glaciers are shrinking at alarming rates, and many scientists believe it is due to changes in climate. Dr. Lonnie Thompson of Ohio State University and Dr. Douglas Hardy of UMass-Amherst discuss glaciers and how they melt, and pay special attention to Africa's tallest mountain, Mt. Kilimanjaro. "Changing Planet" is produced in partnership with the National Science Foundation.

Mountains: top down.  

PubMed

Mountainous regions offer not only essential habitat and resources, including water, to the earth's more than 6 billion inhabitants, but also insights into how the global human habitat works, how it is being changed at the moment as global climates are disrupted, and how the disruption may lead to global biotic and economic impoverishment. At least 600 million of the earth's more than 6 billion humans dwell in mountainous regions. Such regions feed water into all the major rivers of the world whose valleys support most of the rest of us. At least half of the valley dwellers receive part or all of their water from montane sources, many from the melt water of glaciers, others from the annual snow melt. Glaciers are retreating globally as the earth warms as a result of human-caused changes in the composition of the atmosphere. Many are disappearing, a change that threatens municipal water supplies virtually globally. The warming is greatest in the higher latitudes where the largest glaciers such as those of Greenland and the Antarctic Continent have become vulnerable. The melting of ice in the northern hemisphere raises serious concerns about the continued flow of the Gulf Stream and the possibility of massive climatic changes in Scandinavia and northern Europe. Mountains are also biotic islands in the sea life, rich in endemism at the ecotype level. The systematic warming of the earth changes the environment out from under these genetically specialized strains (ecotypes) which are then maladapted and vulnerable to diseases of all types. The process is systematic impoverishment in the pattern conspicuous on mountain slopes with increasing exposure to climatic extremes. It is seen now in the increased mortality and morbidity of plants as climatic changes accumulate. The seriousness of the global climatic disruption is especially clear in any consideration of mountains. It can and must be addressed constructively despite the adamancy of the current US administration. PMID:15575181

Groundwater quality and water-well characteristics in the Kickapoo Tribe of Oklahoma Jurisdictional Area, central Oklahoma, 1948--2011  

USGS Publications Warehouse

In 2012, the U.S. Geological Survey, in cooperation with the Kickapoo Tribe of Oklahoma, compiled historical groundwater-quality data collected from 1948 to 2011 and water-well completion information in parts of Lincoln, Oklahoma, and Pottawatomie Counties in central Oklahoma to support the development of a comprehensive water-management plan for the Tribe’s jurisdictional area. In this study, water-quality data from 155 water wells, collected from 1948 to 2011, were retrieved from the U.S. Geological Survey National Water Information System database; these data include measurements of pH, specific conductance, and hardness and concentrations of the major ions, trace elements, and radionuclides that have Maximum Contaminant Levels or Secondary Maximum Contaminant Levels in public drinking-water supplies. Information about well characteristics includes ranges of well yield and well depth of private water wells in the study area and was compiled from the Oklahoma Water Resources Board Multi-Purpose Well Completion Report database. This report also shows depth to water from land surface by using shaded 30-foot contours that were created by using a geographic information system and spatial layers of a 2009 potentiometric surface (groundwater elevation) and land-surface elevation. Wells in the study area produce water from the North Canadian River alluvial and terrace aquifers, the underlying Garber Sandstone and Wellington Formation that compose the Garber–Wellington aquifer, and the Chase, Council Grove, and Admire Groups. Water quality varies substantially between the alluvial and terrace aquifers and bedrock aquifers in the study area. Water from the alluvial aquifer has relatively high concentrations of dissolved solids and generally is used for livestock only, whereas water from the terrace aquifer has low concentrations of dissolved solids and is used extensively by households in the study area. Water from the bedrock aquifer also is used extensively by households but may have high concentrations of trace elements, including uranium, in some areas where groundwater pH is above 8.0. Well yields vary and are dependent on aquifer characteristics and well-completion practices. Well yields in the unconsolidated alluvial and terrace aquifers generally are higher than yields from bedrock aquifers but are limited by the thickness and extent of these river deposits. Well yields in the alluvium and terrace aquifers commonly range from 50 to 150 gallons per minute and may exceed 300 gallons per minute, whereas well yields in the bedrock aquifers commonly range from 25 to 50 gallons per minute in the western one-third of study area (Oklahoma County) and generally less than 25 gallons per minute in the eastern two-thirds of the study area (Lincoln and Pottawatomie Counties).

Eight mining districts and numerous individual mines ring the eastern Pioneer Mountains, Beaverhead County, Montana, and are within 4 mi of the boundary of the eastern Pioneer area. Mineralized ground peripheral to these districts extends into the area at several places. Three of 12 molybdenum prospects in the Pioneer Mountains are within the eastern Pioneer area. Several areas of Paleozoic carbonate rocks are mineralized or favorably situated with respect to the Pioneer batholith. All such areas have probable resource potential. Detailed studies of structural and stratigraphic controls of ore deposition and its association with intrusive rocks of particular types and ages may be useful in providing the basis for a more precise resource assessment.

Preliminary appraisal of the hydrology of the Blocker area, Pittsburg County, Oklahoma  

USGS Publications Warehouse

Bedrock in the Blocker area of southeastern Oklahoma consists principally of shale, siltstone, and sandstone of the Boggy and Savanna Formations of Pennsylvanian age. These rocks have been folded to form the Panther Mountain syncline on the south and the Kinta anticline on the north. Alluvium along streams is less than 15 feet thick and consists mainly of sandy silt. Water in bedrock is under artesian conditions. Well depths range from 11 to 213 feet and average 75 feet. In 86% of the wells measured, the water level was less than 30 feet below the land surface. Because the rocks have minimal permeability, well yields probably are less than 5 gallons per minute. Ground water is commonly a mixed cation bicarbonate type with dissolved solids ranging from about 300 to 2,000 milligrams per liter. No relationship between water chemistry and well depth or geographic distribution is apparent. Streams in the area are ephemeral and there are extended periods of no flow. Blue Creek was dry 30% of the time during 1976-80 and had flows of less than 0.1 cubic foot per second for at least 80 consecutive days. Stream water is generally a mixed cation sulfate type. The maximum dissolved-solids concentration determined in stream water was 3670 milligrams per liter. Maximum suspended sediment discharge, in tons per day, was about 235 for Blue Creek, 40 for Blue Creek tributary, and 630 for Mathuldy Creek. Silt-clay particles (diameters less than 0.062 millimeter) are the dominant sediment size. Surface mining for coal undoubtedly will have some effect on the environment. The most likely deleterious effects are increased sediment loads in streams and increased mineralization of stream waters. However, these effects should be of only limited extent and duration if appropriate mining and reclamation practices are followed. (USGS)

Assessment of non-hazardous industrial waste codisposal in Oklahoma  

SciTech Connect

This study addresses the issues associated with the codisposal of the diverse non-hazardous industrial wastes (NHIWs) in Oklahoma's municipal sanitary waste landfills (MSWLs). One aspect of the study focused on the selection of a representative cross section of NHIWs, typical of those wastes currently being codisposed in Oklahoma, and to characterize the representative waste streams based on all available physical and chemical data. Following the waste characterizations, a NHIW classification scheme was developed to distinguish amongst the potential risks posed by the different NHIWs if codisposed in municipal landfills. Another aspect of the study examined other state regulatory programs in an effort to determine the overall direction of NHIW codisposal regulations, nationwide. All state agencies were contacted and subsequently interviewed by telephone, followed by a request to send any pertinent literature and/or regulations. A synopsis of each state's general solid waste management practices were included, in addition to any specific details on NHIW regulations and/or handling procedures. The results of this specific survey indicated that a wide spectrum of NHIW regulations and procedures are being implemented nationwide. A final aspect of the study identified the best management and disposal options currently available for the NHIWs requiring codisposal. The basis for the pretreatment and/or disposal recommendations includes data obtained from both the waste characterization documentation and other state programs. Finally, the study made recommendations to the Oklahoma State Department of Health for the step-by-step development of comprehensive NHIW codisposal guidelines and recommendations, i.e., a major objective of this study.

Sulfide mineralization and magnetization, Cement oil field, Oklahoma  

USGS Publications Warehouse

Geochemical, petrographic, and rock-magnetic studies were undertaken to investigate possible sources for reported positive aeromagnetic anomalies over the Cement oil field, Oklahoma. Ferrimagnetic pyrrhotite (monoclinic, Fe7S8 ), intergrown with more-abundant, nonmagnetic pyrite (FeS2), is present in well-cutting, core, and quarry samples at Cement, and it is the only identified source of possible enhanced magnetization in rocks over the field. Magnetite, found only in well cuttings from Cement, is contamination from drilling. Magnetite was considered previously by others to be the source of magnetic anomalies at Cement.

Modeling Seismicity Rate Changes in Oklahoma and Arkansas  

NASA Astrophysics Data System (ADS)

The rate of M?3 earthquakes in the central and eastern US increased beginning in 2009, particularly in regions such as Oklahoma and central Arkansas where fluid injection has occurred (Ellsworth et al., SSA abs, 2012; Horton, SRL, 2012). We compare rate changes observed in Oklahoma, which had a low background seismicity rate before 2009, to rate changes observed in central Arkansas, which had swarms prior to the start of wastewater injection (Chiu et al., BSSA, 1984; Horton, SRL, 2012). In both cases, stochastic Epidemic-Type Aftershock Sequence (ETAS) models (Ogata, JASA, 1988) and statistical tests demonstrate that the background rate of independent events and the aftershock productivity must increase in 2009 in order to explain the observed increase in seismicity. Productivity is lower during the earlier tectonic swarms in Arkansas. The change in aftershock productivity may provide a way to distinguish manmade from natural earthquake rate changes and could provide insights into the physical mechanisms of induced seismicity. We fit the ETAS model, which is based on empirical aftershock scaling laws such as Omori's Law and the Gutenberg-Richter magnitude distribution, to a 1973-2011 USGS PDE catalog of M?3 Oklahoma earthquakes and a 1982-2012 ANSS catalog of M?2.2 Arkansas earthquakes. To determine whether a rate increase is due to a change in background seismicity rate, aftershock productivity, or some combination of the two, we do the following: 1) fit the model parameters to the data, 2) convert origin times to transformed times (Ogata, JGR, 1992), and 3) use Runs and autocorrelation function tests to test the null hypothesis that the transformed times are drawn from a Poisson distribution with constant rate (as expected when no external processes trigger earthquakes besides a constant tectonic loading rate). In both cases a single set of parameters cannot fit the entire time period, suggesting that significant changes in the underlying process occurred. The null hypothesis is rejected in both Oklahoma (p<0.001) and Arkansas (p=0.015). Then, given a change point in 2009 (Ellsworth et al., SSA abs, 2012; Horton, SRL, 2012), we estimate ETAS parameters for both time periods to determine which parameters must vary. Space-time models are unstable due to the low number of events and large location error in the earlier catalogs, but likelihood tests of the temporal models indicate the data are better fit when both background rate and productivity increase.

Oklahoma v. FERC: the waning of cooperative federalism  

SciTech Connect

Oklahoma v. FERC (Federal Energy Regulatory Commission) is an important decision in the development of constitutional interpretations of the tenth amendment after the Supreme Court decision in National League of Cities v. Usery. Even though the legislative provisions of the Natural Gas Policy Act impinge upon state regulatory decision making to a greater degree than earlier environmental legislation, the federal interest in energy price regulation was held to justify the use of state administrative agencies to further federal goals. The extension of federal control over state regulatory machinery narrows the scope of state sovereignty as a limitation on the commerce power. 55 references.

Marion Angell Garza, JEMS editorial/news coordinator, spoke at length with six responders, including paramedics, the triage and treatment officer, a firefighter/EMT-1 and an emergency physician. The following excerpts are from those interviews. PMID:10143265

Ground-water levels in observation wells in Oklahoma, 1975  

USGS Publications Warehouse

The objectives of the observation-well program are (1) to provide long-term records of water-level fluctuations in representative wells, (2) to facilitate the prediction of water-level trends and indicate the future availability of ground-water supplies, and (3) to provide information for use in basic research. These selected records serve as a framework to which other types of hydrologic data may be related. The stratigraphic nomenclature and age determinations used in this report are those accepted by the Oklahoma Geological Survey and do not necessarily agree with those of the U.S. Geological Survey.

Epidemiology of homicide-suicide events: Oklahoma, 1994-2001.  

PubMed

In Oklahoma, all nonnatural deaths must be reported to the Office of the Chief Medical Examiner (ME), whose trained investigators report cause of death using a centralized, statewide, standardized reporting system. The purpose of this study was to determine temporal trends of Oklahoma homicide-suicide events and characterize the epidemiology of these events. By reviewing all ME reports of homicides and suicides from 1994 through 2001, we identified 73 homicide-suicide events resulting in 73 suicides and 89 homicides. Suicidal perpetrators of homicide-suicide events were most often white men aged >or=30 years who killed a current or ex-spouse or intimate partner. Homicide victims tended to be younger women the same race as their killer. Firearms were the predominant method of death in both homicides and suicides, with handguns used most frequently. Divorce/estrangement was the main contributing factor to these events, and the most common relationship type was possessive. The existence of a statewide, centralized, and computerized ME system and the ability to access the detailed information in the ME narratives were critical to identifying homicide-suicide events and obtaining the type of detailed information necessary to fully investigate these events.

Improved Estimates of Evapotranspiration at Oklahoma Mesonet Sites (Invited)  

NASA Astrophysics Data System (ADS)

The Southern Great Plains (SGP) of the United States is a region of dynamic weather and climate. In addition, the SGP region has demonstrated significant coupling between the land surface and atmospheric processes across varying spatial and temporal scales during the warm season. As such, mesocsale events including deep convection as well as regional drought and pluvial periods are impacted by land-atmosphere inter actions and gradients in the surface conditions. With the establishment of the Oklahoma Mesonet in 1994 and subsequent upgrades to the sensors deployed at the over 100 sites across the state, near real-time, collocated observations of soil and atmospheric variables have been collected, quality assured, and archived. At the same time additional observing systems and field campaigns have increased the breadth of the information gathered on soil, vegetation, and atmospheric processes across the SGP region. Such datasets have led (a) to numerous studies that have increased the understanding of how land-atmosphere interactions impact the local weather and climate of the SGP region and (b) new techniques to link in situ observations with remote sensing to provide improved understanding of surface-atmosphere exchange. Most recently, Oklahoma Mesonet soil and atmospheric observations have been combined with near real-time land surface conditions via MODIS remotely sensed data to improve estimates of evapotranspiration at local and regional scales, understand the dynamics of flash drought, and address the water budget of the region.

Image crustal structure of eastern Oklahoma City with TOMODD  

NASA Astrophysics Data System (ADS)

There has been a dramatic increase in earthquake activity in Oklahoma since 2009. This dramatic increase was also matched by a marked increase in the number of operating seismic stations within the region. The additional stations include the Earthscope Transportable Arrays and temporary stations provided by the U. S. Geological Survey. The additional seismic stations and earthquakes provide the ability to do local travel time tomography of the crust within the region. For this study we are focusing on the area near the Jones earthquake swarm, that occurred just east of Oklahoma City, and the M5.6, November 2011 Prague earthquake. Major structures are already known in the area, but little is known about crustal structure below the top of the Precambrian basement. We used regionally available and temporary seismic stations along with more than 2000 earthquakes within the region to develop a 3D tomographic model of the crust using TOMODD. The major structures within the area are the Nemaha Ridge, Wilzetta Fault, and Seminole Uplift, and they and other structures as well are expressed within the tomographic model. We are working on determining the resolution and interpretation of the tomographic images.

Blowup at Yucca Mountain  

SciTech Connect

A theory raising the possibility of atomic explosions in a nuclear waste dump is almost universally dismissed by researchers. But front-page newspaper coverage has turned it into a major part of public debate. This article describes the concerns as detailed in the 5 March New York Times and by the researcher in the center of the debate, Charles Bowman an expert on neutron physics at Los Alamos. The resulting reactions from Congress, from other scientists, from the press, and from US DOE are included, and the possible effect on the Yucca Mountain radioactive waste disposal site.

Environmental Characteristics and Geographic Information System Applications for the Development of Nutrient Thresholds in Oklahoma Streams  

USGS Publications Warehouse

The U.S.Environmental Protection Agency has developed nutrient criteria using ecoregions to manage and protect rivers and streams in the United States. Individual states and tribes are encouraged by the U.S. Environmental Protection Agency to modify or improve upon the ecoregion approach. The Oklahoma Water Resources Board uses a dichotomous process that stratifies streams using environmental characteristics such as stream order and stream slope. This process is called the Use Support Assessment Protocols, subchapter15. The Use Support Assessment Protocols can be used to identify streams threatened by excessive amounts of nutrients, dependant upon a beneficial use designation for each stream. The Use Support Assessment Protocols, subchapter 15 uses nutrient and environmental characteristic thresholds developed from a study conducted in the Netherlands, but the Oklahoma Water Resources Board wants to modify the thresholds to reflect hydrologic and ecological conditions relevant to Oklahoma streams and rivers. Environmental characteristics thought to affect impairment from nutrient concentrations in Oklahoma streams and rivers were determined for 798 water-quality sites in Oklahoma. Nutrient, chlorophyll, water-properties, and location data were retrieved from the U.S. Environmental Protection Agency STORET database including data from the U.S. Geological Survey, Oklahoma Conservation Commission, and Oklahoma Water Resources Board. Drainage-basin area, stream order, stream slope, and land-use proportions were determined for each site using a Geographic Information System. The methods, procedures, and data sets used to determine the environmental characteristics are described.

Depth-Duration Frequency of Precipitation for Oklahoma  

USGS Publications Warehouse

A regional frequency analysis was conducted to estimate the depth-duration frequency of precipitation for 12 durations in Oklahoma (15, 30, and 60 minutes; 1, 2, 3, 6, 12, and 24 hours; and 1, 3, and 7 days). Seven selected frequencies, expressed as recurrence intervals, were investigated (2, 5, 10, 25, 50, 100, and 500 years). L-moment statistics were used to summarize depth-duration data and to determine the appropriate statistical distributions. Three different rain-gage networks provided the data (15minute, 1-hour, and 1-day). The 60-minute, and 1-hour; and the 24-hour, and 1-day durations were analyzed separately. Data were used from rain-gage stations with at least 10-years of record and within Oklahoma or about 50 kilometers into bordering states. Precipitation annual maxima (depths) were determined from the data for 110 15-minute, 141 hourly, and 413 daily stations. The L-moment statistics for depths for all durations were calculated for each station using unbiased L-mo-ment estimators for the mean, L-scale, L-coefficient of variation, L-skew, and L-kur-tosis. The relation between L-skew and L-kurtosis (L-moment ratio diagram) and goodness-of-fit measures were used to select the frequency distributions. The three-parameter generalized logistic distribution was selected to model the frequencies of 15-, 30-, and 60-minute annual maxima; and the three-parameter generalized extreme-value distribution was selected to model the frequencies of 1-hour to 7-day annual maxima. The mean for each station and duration was corrected for the bias associated with fixed interval recording of precipitation amounts. The L-scale and spatially averaged L-skew statistics were used to compute the location, scale, and shape parameters of the selected distribution for each station and duration. The three parameters were used to calculate the depth-duration-frequency relations for each station. The precipitation depths for selected frequencies were contoured from weighted depth surfaces to produce maps from which the precipitation depth-duration-frequency curve for selected storm durations can be determined for any site in Oklahoma.

Statistical Summaries of Streamflow in and near Oklahoma Through 2007  

USGS Publications Warehouse

Statistical summaries of streamflow records through 2007 for gaging stations in Oklahoma and parts of adjacent states are presented for 238 stations with at least 10 years of streamflow record. Streamflow at 120 of the stations is regulated for specific periods. Data for these periods were analyzed separately to account for changes in streamflow because of regulation by dams or other human modification of streamflow. A brief description of the location, drainage area, and period of record is given for each gaging station. A brief regulation history also is given for stations with a regulated streamflow record. This descriptive information is followed by tables of mean and median monthly and annual discharges, magnitude and probability of exceedance of annual instantaneous peak flows, durations of daily mean flow, magnitude and probability of nonexceedance of annual low flows, and magnitude and probability of nonexceedance of seasonal low flows.

Comparing reactions to two severe tornadoes in one Oklahoma community.  

PubMed

The authors compared the effect of the 3 May 1999 F5 and 8 May 2003 F3 tornadoes on the community of Moore, Oklahoma, by canvassing damaged areas after both tornadoes and surveying residents. Significantly more 1999 than 2003 residents reported property damage and injuries. Television and tornado sirens were the most common warnings each year, however, more 1999 residents received and responded to television warnings. Importantly, storm shelters were used more frequently in 2003. Fifty-one per cent of residents who experienced both tornadoes took the same amount of protective action in 2003 as they had in 1999; 22% took less; and 27% took more. Residents who took less action said that the reason for doing so was inadequate warning and shelter. First-hand experience of tornadoes prompts people to heed warnings when adequate notification is received and to take effective protective action when adequate shelter is available. PMID:16108992

Networked Observation of Precipitating Cloud Systems in Oklahoma  

NASA Astrophysics Data System (ADS)

Radars are inherently limited in their ability to resolve fine structure of cloud systems and completely image a volume of space. Both the radial nature of sampling and the issues of beam width mean that upper level features are often missed or poorly resolved. While constant azimuth scans (RHIs) give amazing insight into the vertical structure they are not capable of sampling full storm structure in within a time commensurate with the evolution of the storm system. This presentation will show results from the ARM multi-scale remote sensing facility in Lamont, Oklahoma where there is a network of three X-Band and a C-Band radar deployed. Taking care in quality control and using a flexible mapping methodology enables the combining of information from multiple sources. We will showcase some sample storm reconstructions highlighting the advantages of using the full capabilities of the observing system.

Exploitation and Optimization of Reservoir Performance in Hunton Formation, Oklahoma  

SciTech Connect

West Carney field--one of the newest fields discovered in Oklahoma--exhibits many unique production characteristics. These characteristics include: (1) decreasing water-oil ratio; (2) decreasing gas-oil ratio followed by an increase; (3) poor prediction capability of the reserves based on the log data; and (4) low geological connectivity but high hydrodynamic connectivity. The purpose of this investigation is to understand the principal mechanisms affecting the production, and propose methods by which we can extend the phenomenon to other fields with similar characteristics. In our experimental investigation section, we continue to describe the use of surfactant to alter the wettability of the rock. By altering the wettability, we may be able to recover additional oil through imbibition and gravity drainage process. In our Engineering and Geological Analysis section, we present a new technique to generate alternate permeability distributions at unsampled wells.

Forensic Seismology and the 1995 Oklahoma City Terrorist Bombing  

NASA Astrophysics Data System (ADS)

The terrorist bombing of the Alfred P. Murrah Federal Building in Oklahoma City, Oklahoma, on April 19, 1995, was recorded on 2 permanent seismographs, 7 and 26 km away. The more distant seismograph recorded 2 low-frequency wave trains separated by about 10 s. Militia groups speculated that the 2 wave trains were caused by separate explosions and hinted at a government cover up. Preliminary statements by the scientific community also contributed to the uncertainty. A public science organization issued a press release that stated "the location and source of the second surface wave-recording is unknown. Detailed investigations at the building site may offer an explanation as to the cause and origin of the second event." A prominent professional newsletter reported that the "first event was caused by energy from the explosion and the second from the fall of the building." To understand the seismic phases in the April 19 seismograms, the USGS monitored the demolition of the damaged building on May 23, 1995, with a portable seismic array. The array recorded the same 2 wave trains during the demolition and indicated the wave trains were a propagation effect and not the result of multiple sources. Modeling of the waveforms indicated that the 2 wave trains probably resulted from propagation of seismic energy in a near-surface zone with a strong velocity gradient. The first phase appeared to be a packet of scattered body waves and the second was the fundamental-mode Rayleigh wave. Timely resolution of the ambiguity of the seismogram and publication of results in a refereed publication, EOS, discouraged a conspiracy defense by the terrorists.

The New Robotic Telescope at Oklahoma State University  

NASA Astrophysics Data System (ADS)

A new, 0.6-m robotic telescope of Ritchey-Chrétien design was recently installed at the H. S. Mendenhall Observatory (HSMO) of Oklahoma State University (OSU), and is now undergoing operational tests. Funded by the Air Force Office of Scientific Research through the Defense University Research Instrumentation Program, it replaces HSMO's original 0.35-m Schmidt-Cassegrain telescope. Research programs will include the characterization of near-Earth objects and collaborative searches for transiting exoplanets, programs which will also open up new research opportunities for students in the Oklahoma-Arkansas region. Ideally, these opportunities will attract more undergraduate and graduate students to major in physics and astronomy, and foster the creation of degree programs in astronomy at OSU. Optical Guidance Systems was the contractor for both the telescope and dome automation. The telescope's ceramic 602-mm f/3 primary and 220-mm secondary mirrors yield an effective focal ratio of f/8 that can be changed to f/5.3 with a focal reducer / field flattener. Fields of view range from 0.75° at f/5.3 to 1.2° at f/8. The Strehl ratio is 0.954. The telescope's carbon-fiber Serrurier truss is supported by an equatorial fork mount equipped with friction drives. Telescope equipment includes a 35-mm-format CCD camera with UBVRI filters, field rotator, off-axis guider, and flip-mirror unit for quick switches to eyepiece observing. HSMO itself is conveniently located under reasonably dark skies at an elevation of 340 m about 15 km southwest of the city of Stillwater, whose population, including OSU, is approaching 50,000. HSMO's dome was completed in 2002, and funding is being raised for a control building near the dome. The observatory's URL is www.physics.okstate.edu/observatory.

Porosity trends of nonreservoir and reservoir sandstones, Anadarko basin, Oklahoma  

SciTech Connect

The porosity of nonreservoir sandstones in Caddo County, Oklahoma, is determined using compensated-neutron and formation-density logs. The authors preliminary data set represents more than 3,000 net ft of Pennsylvanian and Permian age sandstones from 12 well locations. These porosity data and the average porosities of sandstone oil and gas reservoirs within the Anadarko basin of Oklahoma are each compared to a broad, composite set of porosity data from numerous basins that represent sandstones in general, and they are also compared to each other. The porosity of nonreservoir sandstones in Caddo County declines predictably as a power function of increasing thermal maturity for vitrinite reflectance (R{sub 0}) of 0.5 to 1.3%. The rate of porosity decrease with increasing thermal maturity is more rapid than that of the average porosity-R{sub 0} trend of the composite set, but is still within the porosity-R{sub 0} envelope of sandstones in general. Hydrocarbon reservoir sandstones of the Anadarko basin, however, follow a different pattern. Their rate of porosity loss is much slower than that of both sandstones in general, and nonreservoir sandstones of Caddo County. This slow rate of porosity decline with increasing R{sub 0} could be due to inhibiting effects of early hydrocarbon emplacement on diagenesis and (or) to the bias of economic selection. In any case, as R{sub 0} increases beyond about 1%, the porosity of Anadarko basin reservoir sandstones is anomalously high compared to both nonreservoir Anadarko basin sandstones and sandstones in general.

Iron Mountain Electromagnetic Results  

SciTech Connect

Iron Mountain Mine is located seventeen miles northwest of Redding, CA. After the completion of mining in early 1960s, the mine workings have been exposed to environmental elements which have resulted in degradation in water quality in the surrounding water sheds. In 1985, the EPA plugged ore stoops in many of the accessible mine drifts in an attempt to restrict water flow through the mine workings. During this process little data was gathered on the orientation of the stoops and construction of the plugs. During the last 25 years, plugs have begun to deteriorate and allow acidic waters from the upper workings to flow out of the mine. A team from Idaho National Laboratory (INL) performed geophysical surveys on a single mine drift and 3 concrete plugs. The project goal was to evaluate several geophysical methods to determine competence of the concrete plugs and orientation of the stopes.

Tectonic deformation and surface denudation are interdependent, however, and feedback mechanisms-in particular, the potential link to climate-are subjects of intense debate. Spatial variations in fluvial denudation rate caused by precipitation gradients are known to provide first-order controls on mountain range width, crustal deformation rates and rock uplift. Moreover, limits to crustal strength are thought to constrain the maximum elevation of large continental plateaus, such as those in Tibet and the central Andes. There are indications that the general height of mountain ranges is also directly influenced by the extent of glaciation through an efficient denudation mechanism known as the glacial buzzsaw. Here we use a global analysis of topography and show that variations in maximum mountain height correlate closely with climate-controlled gradients in snowline altitude for many high mountain ranges across orogenic ages and tectonic styles. With the aid of a numerical model, we further demonstrate how a combination of erosional destruction of topography above the snowline by glacier-sliding and commensurate isostatic landscape uplift caused by erosional unloading can explain observations of maximum mountain height by driving elevations towards an altitude window just below the snowline. The model thereby self-consistently produces the hypsometric signature of the glacial buzzsaw, and suggests that differences in the height of mountain ranges mainly reflect variations in local climate rather than tectonic forces.

Insights into Oklahoma's Increased Seismicity Aided by Incorporation of the Transportable Array in Regional Earthquake Monitoring  

NASA Astrophysics Data System (ADS)

Seismicity rates within Oklahoma increased more than an order of magnitude since 2009 roughly concurrent with the arrival of the Earthscope US Array Transportable Array (TA). It can be demonstrated the increased seismicity is not because of increased monitoring capability, but rather a marked increase in earthquake occurrence rates. This unique confluence of additional monitoring and additional seismicity has lead to new insights about the continuing earthquakes within Oklahoma. The additional seismic stations improved event detection within the region but also dramatically improved accuracy in earthquake locations and enabled the determination of 154 first-motion and moment tensor focal mechanisms throughout Oklahoma. Prior to the passage of the TA few if any focal mechanisms had been determined for earthquakes occurring within Oklahoma. These focal mechanisms show primarily strike-slip faulting on steeply dipping faults with strikes between 40-60° and 130-150°. Focal mechanisms associated with the Jones earthquake swarm, occurring just east of Oklahoma City, have clearly different orientations from those outside of the swarm area. The Jones earthquake swarm has a b-value of 1.3 while the remaining portions of Oklahoma continue to have a b-value near 1, even with the increased seismicity rates. The Jones earthquake swarm continues to average nearly 2 earthquakes each day with characteristics that clearly separate it from the rest of the observed earthquakes in Oklahoma. The additional seismic monitoring that the TA provided also helped to identify and more accurately quantify cases of possibly triggered seismicity throughout Oklahoma. The wells identified in possible cases of triggered seismicity represent a small fraction of all oil and gas activities within Oklahoma, but understanding these cases may help to mitigate such occurrences in the future. Accurately identifying cases of triggered seismicity helps to quantify the potential earthquake hazard induced seismicity may pose both in Oklahoma and throughout the country. The effect on the earthquake hazard for Oklahoma is demonstrated by comparing different probabilistic seismic hazard assessments based on the different observed seismicity rates.

Pathological data on chronic mountain sickness are scarce due to the fact that the disease is ameliorated or cured by descent to a low altitude. In this report we describe a case of chronic mountain sickness occurring in a woman of 48 years at Cerro de Pasco (4,300 m above sea level). The necropsy findings are compared with the limited pathological observations reported by others. It is apparent from our findings that in fatal cases the main changes are located within the pulmonary circulation. So far histological studies have been reported only in cases of the secondary form of chronic mountain sickness. The basic pathology of the primary form (Monge's disease) remains to be defined.

The EMS response to the Oklahoma City bombing.  

PubMed

This is a descriptive study of the Emergency Medical Services response to a bombing of a United States Federal Building in Oklahoma City, Oklahoma on 19 April 1995. The explosion emanated from a rented truck parked in the front of the building. The force of the explosion destroyed three of the four support columns in the front of the building and resulted in a pancaking effect of the upper floors onto the lower floors. There were three distinct phases of the medical response: 1) Immediately available local EMS ambulances and staff; 2) Additional ambulances staffed by recalled, off-duty personnel; and 3) mutual-aid ambulances and personnel from the surrounding communities. There were 361 persons in the building at the time of the explosion, 163 of these perished. Within the first hour of the explosion, 139 patients were transported to area hospitals. Of these, 32% were in critical condition. During the day of the explosion, 444 persons were treated for physical injuries: 410 of these were related to the explosion and 14, including one with fatal injuries, were sustained during search and rescue attempts. A total of 354 (80%) were treated and released from emergency departments, and 90 (20%) were admitted to hospitals. Six of the transported victims either were dead on arrival to the emergency department or died after admission to the hospital. Of those who died, 95% of the deaths were related to blunt trauma associated with the collapse of the structure. Only three persons were extricated alive after the first five hours following the explosion. The scene became flooded with volunteers who, although their intentions were to provide help and aid to those injured, created a substantial logistical problem for Incident Command. Several other lessons were learned: 1) Telephone lines and cells became overloaded, but the Hospital Emergency Administrative Radio system was operational only in three of the 15 hospitals; 2) Volunteer personnel should have responded to the hospitals and not to the scene; and 3) Training was an essential for the success of such a response. Thus, the success of this operation was a function of the intense training, practice, and coordination between multiple agencies. PMID:10187007

Ore microscopy of the Paoli silver-copper deposit, Oklahoma  

USGS Publications Warehouse

The Paoli silver-copper deposit is located in south-central Oklahoma, 56 km south-southeast from Norman, Oklahoma. It was mined for high-grade silver-copper near the beginning of this century, and intensive exploratory drilling during the early 1970's delineated unmined portions of the deposit. A collaborative study between the U.S.G.S., the Kansas Geological Survey, and the University of Missouri-Rolla was undertaken to provide new information on the character of red bed copper deposits of the Midcontinent region. The Paoli deposit has been interpreted to occur as a roll-front type of deposit. The silver and copper mineralization occurs within paleochannels in the Permian Wellington Formation. The silver-copper interfaces appear to be controlled by oxidation-reduction interfaces that are marked by grey to red color changes in the host sandstone. Ore microscopic examinations of polished thin sections show that unoxidized ore consists of chalcocite, digenite, chalcopyrite, covellite and pyrite; and oxidized ores are characterized by covellite, bornite, hematite and goethite. In sandstone-hosted ores, chalcocite and digenite replace dolomite and border clastic quartz grains. In siltstone-hosted ores, the copper sulfide grains have varied shapes; most are irregular in shape and 5-25 ??m across, others have euhedral shapes suggestive of pyrite crystal replacements, and some are crudely spherical and are 120-200 ??m across. Chalcopyrite is the predominant copper sulfide at depth. Covellite and malachite replace chalcocite and digenite near the surface. Silver only occurs as native silver; most as irregularly shaped grains 40-80 ??m across, but some as cruciform crystals that are up to 3.5 mm across. The native silver has been deposited after copper sulfides, and locally replaces chalcocite. Surficial nodules of pyrite, malachite and hematite locally are present in outcrops at the oxidation-reduction fronts. Polished sections of the nodules show that malachite forms a cement around quartz sand grains, and brecciated pyrite grains are surrounded by rims of hematite and goethite. Dolomite is the principal sandstone cement. Cathodoluminescence microscopic study of the mineral has shown that it was deposited during seven periods before the copper sulfide mineralization. ?? 1991.

A comparison of the speech patterns and dialect attitudes of Oklahoma  

NASA Astrophysics Data System (ADS)

The lexical dialect usage of Oklahoma has been well-studied in the past by the Survey of Oklahoma Dialects, but the acoustic speech production of the state has received little attention. Apart from two people from Tulsa and two people from Oklahoma City that were interviewed for the Atlas of North American English, no other acoustic work has been performed within the state. This dissertation begins to fill in these gaps by presenting twelve respondents interviewed by the Research on Dialects of English in Oklahoma (RODEO) project. For each speaker, a brief biography is given, including some of their regional and speech attitudes of Oklahoma. Then acoustic data from a wordlist and reading task are presented and compared. Analysis will consider plots of each speaker's vowel system as a whole, and will also examine many environments in isolation. These environments were chosen for their likely presence in Oklahoma, and include such dialect features as the Southern Shift, the pin/pen merger, the caught/cot merger, monophthongization of the PRICE vowel, and neutralization of tense vowels before /l./ After considering each respondent separately, some of their results will be pooled together to give a preliminary sense of the state of dialect within Oklahoma. Demographic variables such as age, gender, and urban/rural upbringing will be related to speakers' attitudes and acoustic production. This will serve two goals - first, to compare modern-day production to the findings of previous scholars, and second, to suggest a dialect trajectory for the state that could be studied further in additional research.

Geographic Information Systems Methods for Determining Drainage-Basin Areas, Stream-Buffered Areas, Stream Length, and Land Uses for the Neosho and Spring Rivers in Northeastern Oklahoma  

USGS Publications Warehouse

Geographic Information Systems have many uses, one of which includes the reproducible computation of environmental characteristics that can be used to categorize hydrologic features. The Oklahoma Department of Wildlife Conservation and the Oklahoma Department of Environmental Quality are investigating Geographic Information Systems techniques to determine partial drainage-basin areas, stream-buffer areas, stream length, and land uses (drainage basin and stream characteristics) in northeastern Oklahoma. The U.S Geological Survey, in cooperation with Oklahoma Department of Wildlife Conservation and the Oklahoma Department of Environmental Quality, documented the methods used to determine drainage-basin and stream characteristics for the Neosho and Spring Rivers above Grand Lake Of the Cherokees in northeastern Oklahoma and calculated the characteristics. The drainage basin and stream characteristics can be used by the Oklahoma Department of Wildlife Conservation and the Oklahoma Department of Environmental Quality to aid in natural-resource assessments.

Ground water in the alluvium of Beaver Creek basin, Oklahoma  

USGS Publications Warehouse

Beaver Creek is an 857 square-mile area in south-central Oklahoma. The tributaries head at an altitude as high as 1,400 feet and the mouth of Beaver Creek is at an altitude of 804 feet. Alluvial material has been deposited along all the major streams in the basin. The alluvium contains a high percentage of clay and fine sand and ranges in thickness from a few inches to 50 feet. Replenishment of water in the alluvium is from precipitation, lateral seepage and runoff from adjoining areas, and infiltration from the streams during high flows. The town of Ryan and Waurika have constructed municipal water-supply wells topping the alluvium and residents of the town of Sugden have private wells topping the alluvium. The other major use of ground water is transpiration by trees, which are very dense where the alluvial plain is wide. In the northern part of the basin the alluvium is thin and only domestic water supplies are available. (available as photostat copy only)

Exploitation and Optimization of Reservoir Performance in Hunton Formation, Oklahoma  

SciTech Connect

West Carney field--one of the newest fields discovered in Oklahoma--exhibits many unique production characteristics. These characteristics include: (1) decreasing water-oil ratio; (2) decreasing gas-oil ratio followed by an increase; (3) poor prediction capability of the reserves based on the log data; and (4) low geological connectivity but high hydrodynamic connectivity. The purpose of this investigation is to understand the principal mechanisms affecting the production, and propose methods by which we can extend the phenomenon to other fields with similar characteristics. In our experimental investigation section, we continue to describe the use of surfactant to alter the wettability of the rock. By altering the wettability, we should be able to change the water-gas ratio in the reservoir and, hence, improve productivity from the well. In our Engineering and Geological Analysis section, we present our rock typing analysis work which combines the geological data with engineering data to develop a unique rock characteristics description. By using porosity as a variable, we can generate alternate rock type descriptions at logged wells. This procedure also allows us to quantify uncertainties in rock type description.

Modified fracs increase recovery from Oklahoma tight formations  

SciTech Connect

Staged fracture stimulations with high sand concentrations have added recoverable reserves and improved the economics for developing tight formations in the Golden Trend of southern Oklahoma. Since the early 1950s, the Sycamore and Hunton formations have been recognized as formations requiring fracture stimulation for commercial production. Throughout the trend, numerous frac techniques have been used to stimulate the massive interval. Until 1992, high volume, slick water, and modified Kiel fracs were the favorite treatments because of low cost and relatively high initial producing rates. Because of the low gas prices that continued into the early part of 1992, new completions in the Golden Trend were attractive to only those companies that could take advantage of Section 29 tax credits. However, of the low gas prices that continued into the early part of 1992, new completions in the Golden Trend were attractive to only those companies that could take advantage of Section 29 tax credits. However, Chesapeake Energy Corp. could not use the tax credits and therefore focused on increasing gas recoveries and the rate of return from this area. By re-engineering the traditional completion and drilling practices, Chesapeake Energy added more than 1 bcf and 20,000 bbl of oil/well. Ultimate recoveries from each well are about 1.5--2.0 bcf and 30,000--40,000 bbl of oil. The paper describes the frac design, the frac team, treatment procedures, and production results after the first six months from 44 completions.

Turbulent Kinetic Energy in the Oklahoma City Urban Environment  

SciTech Connect

A major field experiment, Joint URBAN 2003 (JU2003), was conducted in Oklahoma City in July 2003 to collect meteorological and tracer data sets for evaluating dispersion models in urban areas. The Department of Homeland Security and the Defense Threat Reduction Agency were the primary sponsors of JU2003. Investigators from five Department of Energy national laboratories, several other government agencies, universities, private companies, and international agencies conducted the experiment. Observations to characterize the meteorology in and around the urban area complemented the observation of the dispersion of SF6, an inert tracer gas. Over one hundred threedimensional sonic anemometers were deployed in and around the urban area to monitor wind speed, direction, and turbulence fluxes during releases of SF6. Sonic deployment locations included a profile of eight sonic anemometers mounted on a crane less than 1 km north of the central business district (CBD). Using data from these and other sonic anemometers deployed in the urban area, we can quantify the effect of the urban area on atmospheric turbulence and compare results seen in OKC to those in other urban areas to assess the parameters typically used in parameterizations of urban turbulence.

Oklahoma Cherokee formation study shows benefits of gas tax credits  

SciTech Connect

To no one's surprise, the administration's recently released energy initiative package does not advocate the use of tax incentives such as the Internal Revenue Code Sec. 29 (tight sand gas) credit that expired Dec. 31, 1992. This is unfortunate since tax credits do stimulate drilling, as the authors' recent study of Oklahoma's Pennsylvanian age Cherokee formation demonstrates. Within this 783,000 acre study area, more than 130 additional wells were drilled between 1991--92 because of tax credit incentives. And such tax credits also increase total federal tax revenues by causing wells to be drilled that would not have been drilled or accelerating the drilling of wells, thereby increasing taxable revenue. In short, tax credits create a win-win situation: they stimulate commerce, increase tax revenues, reduce the outflow of capital to foreign petroleum projects, and add to the nation's natural gas reserve, which is beneficial for national security, balance of payments, the environment, and gas market development. The paper discusses the study assumptions, study results, and the tax credit policy.

Multispectral analysis of limestone, dolomite, and granite, Mill Creek, Oklahoma  

NASA Technical Reports Server (NTRS)

Spectral reflectance and thermal emission data were collected at the Mill Creek, Oklahoma test site during NASA missions 132 and 133 in June 1970. The data were collected by three aircraft flown several times during the diurnal cycle at altitudes of 150 to 17,000 m above mean terrain. Reflectance of the main rock types (limestone, dolomite, and granite) was determined from the data collected using a 12-channel multispectral scanner during mission 133 and from thermal infrared images recorded during mission 132 on an RS-7 scanner from 17,000 m above terrain. A preliminary rock recognition map was generated automatically using data collected from 900 m above terrain. The discrimination provided by the map is reasonably accurate. Misidentification occurred in areas of unusually high dolomite reflectivity. High altitude thermal infrared (10 to 12 micrometers) images show regional folds and faults distinguished by the presence of thermally contrasting materials. Linear and curvilinear structural features two to three times smaller than the nominal 17 m resolution could be detected.

Subsidence and basin development in the southern Oklahoma aulacogen  

SciTech Connect

Development of the southern Oklahoma aulacogen was the result of Cambrian tectonism along Proterozoic zones of weakness that caused northwest-trending extensional normal faults related to a rifting event. These faults were reactivated during upper Paleozoic compressional stress with fault patterns indicative of sinistral transpressive and transtensional movement. Mapping in the region has allowed classification of the myriad of faults into six major systems, from the north to south: the Washita Valley, Madill-Aylesworth, Caddo, Criner, Horseshoe Bend, and Muenster systems. Development of the fault systems occurred somewhat independently as energy was transferred between them owing to changes in stress from the uneven collision of the Ouachita front. This model may account for the episodic movement recognized by past investigators. The determination of relative timing of development within these systems has shown that the Madill-Aylesworth and Criner systems were active during the Upper Mississippian. As deformation continued along the Criner system structural activity moved southward to include the Horseshoe Bend and Muenster systems during the Early Pennsylvanian. During the Middle Pennsylvanian, fault development along the southern margin of the aulacogen subsided, and deformation activity was initiated in the northern portions of the Ardmore basin. The amount of horizontal displacement along fault systems in the region is still unresolved. However, by regional mapping along the Criner systems, a minimum of 6 mi left-lateral movement can be documented as having occurred during the Upper Pennsylvanian using models of sediment deposition and transport in strike-slip basins.

Hydrometeorology of Rocky Mountain floods  

NASA Astrophysics Data System (ADS)

Climatology and flood hydrology of the Rocky Mountains were the topics of a workshop held in Lakewood, Colo., October 4-5, 1990. Ninety-one people participated in the workshop, which was organized by Robert Jarrett, U.S. Geological Survey, Denver; John Liou, Federal Emergency Management Agency, Denver; and Doug Laiho, Delta Environmental Consultants, Boulder, representing the American Society of Civil Engineers.The workshop was held to address some of the recognized complexities in the hydrometeorology of floods in the Rocky Mountains. The complexities are caused by the effects of rough mountain terrain on meteorology, snowmelt and rainfall flooding, and limited rainfall and streamflow data. The current theories and methods used to estimate flood flows in the Rocky Mountains, particularly estimation of the probable maximum precipitation (PMP) and the probable maximum flood (PMF), have been questioned by hydrologists and engineers for some time. Purposes of the workshop were to review the current understanding and ongoing research of floods—both frequent and extreme, including the PMF, in the Rocky Mountains; to bring together scientists, engineers, and flood-plain managers in government, industry, consulting firms, and universities; and to provide a mechanism for the exchange of ideas and technology between climatologists, meteorologists, hydrologists, engineers, and managers.

The station is located near the western headwaters of Forty Mile Wash on the Nevada Test and Training Range (NTTR). Overland flows from precipitation events that occur in the Timber Mountain high elevation area cross several of the contaminated Soils project CAU (Corrective Action Unit) sites located in the Forty Mile Wash watershed. Rain-on-snow events in the early winter and spring around Timber Mountain have contributed to several significant flow events in Forty Mile Wash. The data from the new precipitation gauge at Timber Mountain will provide important information for determining runoff response to precipitation events in this area of the NNSS. Timber Mountain is also a groundwater recharge area, and estimation of recharge from precipitation was important for the EMSI project in determining groundwater flowpaths and designing effective groundwater monitoring for Yucca Mountain. Recharge estimation additionally provides benefit to the Underground Test Area Sub-project analysis of groundwater flow direction and velocity from nuclear test areas on Pahute Mesa. Additionally, this site provides data that has been used during wild fire events and provided a singular monitoring location of the extreme precipitation events during December 2010 (see data section for more details). This letter report provides a summary of the site location, equipment, and data collected in fiscal year 2011.

Monitoring temperature conditions in recently drilled nonproductive industry boreholes in Oklahoma  

SciTech Connect

Temperature conditions were monitored in seven industry petroleum-test wells (called holes-of-opportunity in this report) that were drilled in central and eastern Oklahoma. Five of these wells provided useful temperature information, and two wells were used to determine the length of time needed for the borehole-fluid temperature to achieve thermal equilibrium with the formation rocks. Four wells were used to verify the validity of a geothermal-gradient map of Oklahoma. Temperature surveys in two wells indicated a gradient lower than the predicted gradients on the geothermal-gradient map. When deep temperature data, between 5000 and 13,000 feet, are adjusted for mud-circulation effects, the adjusted gradients approximate the gradients on the geothermal-gradient map. The temperature-confirmation program appears to substantiate the geographic distribution of the high- and low-thermal-gradient regimes in Oklahoma. 13 refs., 18 figs., 7 tabs.

Chemical quality of surface waters in the Arkansas River basin of Oklahoma  

USGS Publications Warehouse

One of the first requisites for intelligent planning of the utilization and control of water and for the administration of laws relating to its use, is data on the quantity, quality, and mode of occurence of water supplies. The collections, evaluation, interpretation, and publication of such data constitute the primary function of the Water Resources Division of the United States Geological Survey. Since 1895 the Congress has made appropriations to this agency for investigations of the water resources of the Nation. In 1929 the Congress adopted the policy of dollar-for-dollar cooperation with State and local governmental agencies for water-resources investigations. The Geological Survey's Federal-State cooperative program of quality-of-water investigations in Oklahoma was started in 1944 in cooperation with the Oklahoma Planning and Resources Board. Since July of this year the program has been carried on cooperatively with the newly created Oklahoma Water Resources Board. (available as photostat copy only)

The 3D Elevation Program: summary for Oklahoma  

USGS Publications Warehouse

Elevation data are essential to a broad range of applications, including forest resources management, wildlife and habitat management, national security, recreation, and many others. For the State of Oklahoma, elevation data are critical for flood risk management, infrastructure and construction management, agriculture and precision farming, natural resources conservation, wildlife and habitat management, and other business uses. Today, high-density light detection and ranging (lidar) data are the primary sources for deriving elevation models and other datasets. Federal, State, Tribal, and local agencies work in partnership to (1) replace data that are older and of lower quality and (2) provide coverage where publicly accessible data do not exist. A joint goal of local, State, and Federal partners is to acquire consistent, statewide coverage to support existing and emerging applications enabled by lidar data. The National Enhanced Elevation Assessment (NEEA; Dewberry, 2011) evaluated multiple elevation data acquisition options to determine the optimal data quality and data replacement cycle relative to cost to meet the identified requirements of the user community. The evaluation demonstrated that lidar acquisition at quality level 2 for the conterminous United States and quality level 5 interferometric synthetic aperture radar (ifsar) data for Alaska with a 6- to 10-year acquisition cycle provided the highest benefit/cost ratios. The 3D Elevation Program (3DEP) initiative selected an 8-year acquisition cycle for the respective quality levels. 3DEP, managed by the U.S. Geological Survey (USGS), the Office of Management and Budget Circular A–16 lead agency for terrestrial elevation data, responds to the growing need for high-quality topographic data and a wide range of other 3D representations of the Nation’s natural and constructed features.

Geological report on water conditions at Platt National Park, Oklahoma  

USGS Publications Warehouse

Platt National Park, located in southern Oklahoma, containing 842 acres, was established by Acts of Congress in 1902, 1904, and 1906. The reason for the setting aside of this area was the presence in the area of some 30 'mineral' springs, the water from which contains sulphur, bromide, salt, and other minerals, which are believed to possess medicinal qualities. For many generations the sulphur springs of the Chickasaw Nation had been known for their reputed healing qualities. It had long been the custom for families to come from considerable distances on horseback and in wagons and camp near the springs, in order to drink the water. In course of time a primitive town, known as Sulphur Springs, grew up near a group of springs known since as Pavilion Springs at the mouth of Sulphur Creek, now known as Travertine Creek. This town was still in existence at the time of my first visit to the locality in July, 1901. At this time, in company with Joseph A. Taff, of the United States Geological Survey, I spent a week riding over the country making a preliminary survey looking toward the setting aside of the area for a National Park. After the establishment of the National Park, the old town of Sulphur Springs was abandoned, and when the present boundaries of the park had been established the present town of Sulphur, now county seat of Murray County, grew up. In July 1906, on request of Superintendent Joseph F. Swords, I visited the park and made an examination of the various springs and submitted a report, dated August 15, 1906, to Secretary of the Interior E.A. Hitchcock. Copies of this report are on file in the Regional Office and at Platt National Park. In this report I set forth the approximate amount of flow of the various springs, the character of the water in each, and the conditions of the springs as of that date. I also made certain recommendations regarding proposed improvements of each spring. In this report I say: 'In the town of Sulphur, four wells have been drilled to a depth of between 450 and 500 feet in which artesian water has been secured. These wells are said to flow 200,000 gallons each per day.' I also say: 'From a study of the log of one of these wells, it appears that the artesian water is derived from the upper part of the Simpson sandstone. It is very probable that the water of the springs is derived from the same source.' This early was recognized the relation between the water from the mineral springs and that from the artesian wells. As the years have passed, other wells have been drilled in the town of Sulphur, chiefly to supply water for mineral baths and for swimming pools, so that to date more than 30 wells have been drilled. The exact number is not known. The custom has usually been to turn the wells loose and permit them to flow at full capacity, although some of the wells have been 'valved in' and the flow reduced. An estimate furnished me by the Secretary of the Chamber of Commerce in 1937, referred to later in this report, indicated that at that time 16 wells were flowing approximately 28,800,000 gallons of water per day, practically all of which ran to waste. For many years geologists in Oklahoma and elsewhere have watched this unrestricted waste of water from the artesian wells at Sulphur with growing concern. Remembering the history of other artesian basins throughout the world, these geologists believed that in all probability it was only a question of time until the water in the Sulphur artesian basin would begin to fail. On two different occasions the State Geologist of Oklahoma, bearing these conditions in mind, has prepared and had introduced into the State Legislature a bill which, if enacted into law, would have regulated the flow of water in artesian wells throughout the State. Both bills died in committee. Partly on account of the drought of the past three years, the matter has been brought to a head. In September 1938, Buffalo and Antelope Springs at the hea

Estimate of self-supplied domestic water use in Oklahoma during 1980  

USGS Publications Warehouse

Reported or measured water-use data for the domestic self-supplied user were not available for Oklahoma; therefore estimates of water use within this classification were derived. The total self-supplied population in Oklahoma during 1980 was estimated to be 343,615, which was 11.4 percent of the total 1980 State population. The rate of water use by this group was estimated to be 56 gallons per capita per day. The estimated annual domestic self-supplied water use by county ranged from 10 to 1,180 acre-feet, with a total statewide use of 21,610 acre-feet.

Physiology of ski mountaineering racing.  

PubMed

The aim of this study was to quantify and describe the exercise intensity of ski mountaineering racing, and to identify the best physiological predictors of ski mountaineering racing. Before participating in the race in which heart rate (HR) and speed were continuously recorded, 10 trained ski-mountaineers performed a field maximal test to determine the first ventilatory threshold (VT1) and the respiratory compensation threshold (RCT) in order to establish 3 exercise intensity zones (Z1: below VT1, Z2: between VT1 and RCT, and Z3: above RCT). Energy cost (EC) of each subject was estimated on the HR/ V?O2 relationship obtained during the field maximal test. VT1 and RCT threshold were equal to 84.2±3.0 and 94.5±1.7% of HR (max). Race time was significantly correlated with V?O2max (r = -0.87), VT1 (r = -0.82) and RCT (r = -0.85) expressed for body mass unit. The mean race time and the mean HR were 101±11?min and 93.4±1.8% of HR (max). The % race time spent in Z1, Z2 and Z3, were 7.0±4.8, 51.3±4.7 and 42.0±6.5%, respectively. The mean value of EC during the two uphill of the race was 14.3±2.6 J x kg(-1) x m(-1). HR and speed decreased significantly during the second uphill whereas EC increased significantly by ?15%. Data obtained in the present study represent the first qualitative description of physiology demand of ski mountaineering racing. The long period of time spent just below and above RCT suggest that ski-mountaineering can be viewed as one of the most strenuous endurance sports like cross-country skiing, running and off-road biking. In addition to high aerobic capacities, body mass seems to appear as a key factor given that performance in ski mountaineering is strongly correlated to relative common physiological variables. The changes of HR, speed and EC during the second uphill, which indicate the prevalence of fatigue, confirm the exhaustive character of ski mountaineering. PMID:22012642

Geohydrology of the alluvial and terrace deposits of the North Canadian River from Oklahoma City to Eufaula Lake, central Oklahoma  

USGS Publications Warehouse

This investigation was undertaken to describe the geohydrology of the alluvial and terrace deposits along the North Canadian River between Lake Overholser and Eufaula Lake, an area of about 1,835 square miles, and to determine the maximum annual yield of ground water. A 1982 water-level map of the alluvial and terrace aquifer was prepared using field data and published records. Data from test holes and other data from the files of the U.S. Geological Survey and the Oklahoma Water Resources Board were used to establish the approximate thickness of the alluvial and terrace deposits. The North Canadian River from Lake Overholser, near Oklahoma City, to Eufaula Lake is paralleled by a 2- to 3-mile wide band of alluvium. Scattered terrace deposits on either side of the alluvium reach an extreme width of 8 miles. Rocks of Permian age bound the alluvial and terrace deposits from the west to the midpoint of the study area; Pennsylvanian rocks bound the alluvial and terrace deposits from that point eastward. Three major aquifers are present in the study area: the alluvial and terrace aquifer, consisting of alluvium and terrace deposits of Quaternary age in a narrow band on either side of the North Canadian River; the Garber-Wellington aquifer of Permian age, consisting of an upper unconfined zone and a lower confined zone separated by relatively impermeable shales; and the Ada-Vamoosa aquifer of Pennsylvanian age. At locations were the alluvial and terrace aquifer overlies either of the other aquifers, there is hydraulic continuity between the alluvial and terrace aquifer and the other aquifers, and water levels are the same. Most large-scale municipal and industrial pumping from the Garber-Wellington aquifer is from the lower zone and has little discernible effect upon the alluvial and terrace aquifer. The total estimated base flow of the North Canadian River for the studied reach is 264 cubic feet per second. Evapotranspiration from the basin in August is about 60 cubic feet per second for the North Canadian River from Lake Overholser to a measuring station above Eufaula Lake. Estimated recharge rates to the alluvial and terrace aquifer in the basin range from 1.7 inches at the west edge of the study area to 7.0 inches at the east edge. Total permitted withdrawal from the aquifer, according to records of the Oklahoma Water Resources Board, ranged from 2,107 acre-feet per year in 1942 to about 21,415 acre-feet per year in 1982. Simulations of the alluvial and terrace aquifer from Lake Overholser to Eufaula Lake were made using a finite-difference model developed by McDonald and Harbaugh (1984). The area of the aquifers was subdivided into a finite-difference grid having 30 rows and 57 columns with cells measuring 1 mile in the north-south direction and 2 miles in the east-west direction. The model was calibrated in two steps: A steady-state calibration simulated head distribution prior to extensive pumping of the aquifer in 1942, and a transient calibration simulated head distribution after extensive pumpage. The final horizontal hydraulic conductivity used for the alluvial and terrace aquifer was 0.0036 feet per second (310 feet per day) at all locations. The recharge rate for the alluvial and terrace aquifer ranged from 1.7 inch per year in the west to 7.0 inches per year in the east, and averaged about 3.3 inches per year. A specific yield of 15 percent was used for the transient simulation. Permitted pumpage for 1942 through 1982 was used in the digital model to estimate the annual volume of water in storage in the alluvial and terrace aquifer for the years for this time period. The 1982 permitte
