    The early Late Permian (Kubergandian to Midian) Iwaizaki Limestone of the South Kitakami Terrane, situated in Northeast Japan, represents a coral reef complex which was formed on a faulted-bank in an active continental margin. The reef-building organisms include cerioid and dendroid rugose corals, a fasciculate tabulate coral and solenoporacean algae as constructors, calcisponges, bryozoans and crinoids as bafflers, and Tubiphytes, Archaeolithoporella and cyanobacteria as binders. The biotic composition is more diverse than the other coeval reefs. Characterized by the existence of an obvious framework, this reef is similar to the Recent coral reefs and unique among Late Permian reefs, most of which are mainly formed by calcisponges and calcareous algae. The distribution of Late Permian reefs is closely related to the palaeoclimate. Coral reefs were developed mainly around the South China and Indochina continental masses between the Tethys Sea and the Panthalassa Ocean, in the tropics. While, calcisponge reefs and Tubiphytes-algal crust reefs were common in tropical to subtropical regions, and stromatolite-bryozoan reefs developed in arid areas. The gradational distribution of Late Permian organic reefs including localized development of coral reefs were probably caused by decreasing of the glaciers and changing of the ocean current systems.

    Marine magnetic and gravity data from the northeast Japan forearc offer insight to the subsurface structure, density and magnetization from which geologic interpretations and tectonic reconstructions can be made. Positive marine magnetic anomalies, on-land geology, drill hole data, and 2-1/2-dimensional models reveal that Kitakami plutons and possibly their associated volcanic rocks constitute part of the modern forearc basement and lie 100-150 km further east than previously thought. A method to create magnetization and density contrast maps was employed to produce a three-dimensional picture of the forearc basement rock properties averaged over a 14-km thickness. -Author

    This is neither an impact crater nor a volcano. It is a perfect circular intrusion, about 10 km in diameter with a topographic ridge up to 600 m high. The Kondyor Massif is located in Eastern Siberia, Russia, north of the city of Khabarovsk. It is a rare form of igneous intrusion called alkaline-ultrabasic massif and it is full of rare minerals. The river flowing out of it forms placer mineral deposits. Last year 4 tons of platinum were mined there. A remarkable and very unusual mineralogical feature of the deposit is the presence of coarse crystals of Pt-Fe alloy, coated with gold. This 3-D perspective view was created by draping a simulated natural color ASTER composite over an ASTER-derived digital elevation model.

    The image was acquired on June 10, 2006, and is located at 57.6 degrees north latitude, 134.6 degrees east longitude.

    Abstract The potential fish species pool of the Kubo, Tochikura, and Ichinono river systems (tributaries of the Iwai River, Kitakami River drainage), Iwate Prefecture, northern Japan, was compared with the observed ichthyofauna by using historical records and new field surveys. Based on the literature survey, the potential species pool comprised 24 species/subspecies but only 20, including 7 non-native taxa, were recorded during the fieldwork. The absence during the survey of 11 species/subspecies from the potential species pool suggested either that sampling effort was insufficient, or that accurate determination of the potential species pool was hindered by lack of biogeographic data and ecological data related to the habitat use of the species. With respect to freshwater fish conservation in the area, Lethenteron reissneri, Carassius auratus buergeri, Pseudorasbora pumila, Tachysurus tokiensis, Oryzias latipes, and Cottus nozawae are regarded as priority species, and Cyprinus rubrofuscus, Pseudorasbora parva, and Micropterus salmoides as targets for removal.

    Anorthosite massifs developed approximately 1.4 to 1.5 billion years ago along an arch which developed parallel to a zone of continental separation as a block which included North America, Europe, and probably Asia separated from a block which included parts of South America, Africa, India, and Australia. Anorthosite massifs also developed at the same time along a belt which runs through the continents which comprise Gondwanaland (South America), Africa, India, Australia, and Antarctica. This was a zone of continental separation which subsequently became a zone of continental collision about 1.2 billion years ago. The northern anorthosite belt also parallels an orogenic belt which was active between 1.8 and 1.7 billion years ago. Heat generated during this mountain building period helped in the formation of the anorthosites.

  6. Evolution of stocks and massifs from burial of salt sheets, continental slope, northern Gulf of Mexico

    Salt structures in a 4000-km{sup 2} region of the continental slope, the northeast Green Canyon area, include stocks, massifs, remnant structures, and an allochthonous sheet. Salt-withdrawal basins include typical semicircular basins and an extensive linear trough that is largely salt-free. Counterregional growth faults truncate the landward margin of salt sheets that extend 30-50 km to the Sigsbee Escarpment. The withdrawal basins, stocks, and massifs occur within a large graben between an east-northeast-trending landward zone of shelf-margin growth faults and a parallel trend of counterregional growth faults located 48-64 km basinward. The graben formed by extension and subsidence as burial of the updip portion of a thick salt sheet produced massifs and stocks by downbuilding. Differential loading segmented the updip margin of the salt sheet into stocks and massifs separated by salt-withdrawal basins. Initially, low-relief structures evolved by trap-door growth as half-graben basins buried the salt sheet. Remnant-salt structures and a turtle-structure anticline overlay a salt-weld disconformity in sediments formerly separated by a salt sheet. Age of sediments below the weld is inferred to be be late Miocene to early Pliocene (4.6-5.3 Ma); age of sediments above the weld is late Pliocene (2.8-3.5 Ma). The missing interval of time (1-2.5 Ma) is the duration between emplacement of the salt sheet and burial of the sheet. Sheet extrusion began in the late Miocene to early Pliocene, and sheet burial began in the late Pliocene in the area of the submarine trough to early Pleistocene in the area of the massifs.

  7. Exhumation of the Sucking-Dayman Massif, Papua New Guinea

    Extension, evident as seafloor spreading in the Woodlark Basin, is actively propagating into the continental crust of Eastern Papua New Guinea, where regional ductile shear zones and brittle faults have recently exhumed metabasite rocks of the Suckling-Dayman Massif (9.5-10°S, 149-150°E). Utilising field, petrographic microscope and electron microprobe analyses, we investigate the structural and kinematic evolution of the Dayman shear zone, as well as the mineral chemistry of key metamorphic assemblages that define the shear zone fabrics. The results of this investigation indicate that the Dayman shear zone is an extensional shear zone with top to the north-northeast transport. Macro- and micro-kinematic indicators in the ductile shear zone include common S-C fabric, mantled porphyroclasts, `mica' fish, pressure shadows on pyrite, grain-scale faults, and asymmetric micro-boudinage. Kinematic indicators display a very regular sense of shear consistent with a simple shear dominated shear zone. The shear zone fabric is defined by dominantly greenschist facies metamorphic assemblages including abundant chlorite, epidote, albite and quartz with or without actinolite, titanite and calcite. Low strain pods within the shear zone display relict mafic igneous textures and relict clinopyroxene. The pods may include metamorphic lawsonite and blue amphibole in the mineral assemblage, suggestive of high P/T metamorphism of the metabasite massif prior to exhumation. Sedimentary rocks of the hanging wall include the Gwoira Conglomerate that contains clasts of low-grade (prehnite-pumpellyite facies) sheared metabasite. Metamorphic minerals identified in clasts include prehnite, pumpellyite, chlorite, albite, quartz and epidote. Monomineralic clasts include clinopyroxene, albite and quartz. The majority of clasts are consistent with a low-grade metabasite source that may or may not be sheared. A minor component of the clasts include graphitic intergrowths of quartz and feldspar, consistent with a pegmatitic to felsic source. Rare horizons in the Gwoira Conglomerate contain abundant shallow marine fossils. These observations suggest that the provenance for the Gwoira Conglomerate may include early exhumed low-grade metabasite of the Suckling- Dayman massif and that Gwoira Conglomerate may have been deposited on the flanks of the actively exhuming massif. A lack of metamorphism or ductile deformation in the Gwoira Conglomerate supports this interpretation.

  8. Structural geology and sedimentology of the Sermat Quartzites, Strandja Massif, NW Turkey

    Yaz?c?, Müge; Natal'in, Boris A.

    2015-04-01

    The Strandja Massif, NW Turkey, is the eastern continuation of the Rhodope Massif in Bulgaria. The massif is generally correlated with the Hercynian orogenic belt that was later modified by the Cimmerian orogeny. The basement of the massif is composed by various kinds of gneisses and schists, which are intruded by the metagranites. In the studied area, the Cambrian K-feldspar metagranites are unconformably overlain by metaclastics, where both units have fault contacts with volcano-sedimentary rocks. The metagranite intrusions yield Carboniferous U-Pb zircon ages (Natal'in et al., 2012a). All of them constitute the basement of the Strandja Massif. Cambrian age of metagranites and their subduction related nature as well as the subduction related nature of the Carboniferous igneous rocks suggest a prolong evolution of the Strandja Massif (Natal'in et al., 2012a). The Cambrian metagranites are unconformably overlain by a metasedimetary cover unit, which is known in the literature as the ?ermat Quartzite of presumably Permo-Triassic age (Ça?layan and Yurtsever, 1998). In the studied region, detrital zircons extracted from quartzites show that their depositional age is not younger than the Ordovician (Natal'in et al., 2012a). The basement of the Strandja Massif is subjected to the epidote-amphibolite-greenschist facies of metamorphism and high strain deformation in the late Jurassic - early Cretaceous times. The ?ermat Quartzite forms a transgressive sequence, which starts with metaconglomerates, metasandstones and grades up to quartz-sericite schists. The thickness of bedding changes from thin to medium with parallel bedding planes, containing lens-shaped bodies of massive quartzites. The late Jurassic - early Cretaceous foliation (S1) is generally parallel to the primary bedding plane. Foliations and lineations consistently dip to the northeast and kinematic indicators suggest a tectonic transport in the same direction. High strain in the ?ermat Quartzite prevented the preservation of sedimentary structures such as flute casts and cross-beddings, which can be used to determine the sedimentary environments of the ?ermat Basin. Nevertheless, all available relicts indicate the transportation of sediments from a source area in the south. If the ?ermat Quartzites is Ordovician age, they can be correlated with the Ordovician rocks of the Istanbul Zone, which is interpreted as a south-facing passive continental margin. Sedimentological framework of the ?ermat Quartzites contradicts this correlation. Further studies of the region are necessary in order to determine the connection between the Strandja Massif and the Istanbul Zone.

  9. The Lassell Massif - a Silicic Lunar Volcano

    Lunar volcanic processes were dominated by mare-producing basaltic extrusions. However, limited occurrences of non-mare, geochemically evolved (Si-enriched) volcanic deposits have long been suspected on the basis of spectral anomalies (red spots), landform morphologies, and the occurrence of minor granitic components in Apollo sample suites [e.g., 1-5]. The LRO Diviner Lunar Radiometer Experiment (Diviner) measured thermal emission signatures considered diagnostic of highly silicic rocks in several red spot areas [6,7], within the Marius domes [8], and from the Compton-Belkovich feature on the lunar farside [9]. The present study focuses on the Lassell massif red spot (14.73°S, 350.97°E) located in northeastern Mare Nubium near the center of Alphonsus A crater. Here we use Diviner coverage co-projected with Lunar Reconnaissance Orbiter Camera (LROC) images [10] and digital elevation models to characterize the Lassell massif geomorphology and composition. Localized Diviner signatures indicating relatively high silica contents correlate with spatially distinct morphologic features across the Lassell massif. These features include sub-kilometer scale deposits with clear superposing relationships between units of different silica concentrations. The zone with the strongest signal corresponds to the southern half of the massif and the Lassell G and K depressions (formerly thought to be impact craters [11]). These steep-walled pits lack any obvious raised rims or ejecta blankets that would identify them as impact craters; they are likely explosive volcanic vents or collapse calderas. This silica-rich area is contained within the historic red spot area [4], but does not appear to fully overlap with it, implying compositionally distinct deposits originating from the same source region. Low-reflectance deposits, exposed by impact craters and mass wasting across the massif, suggest either basaltic pyroclastics or minor late-stage extrusion of basaltic lavas through vents within the structure. The Lassell massif is thus a volcanic construct with a range of silica concentrations. Based on landform morphology, some deposits appear enriched enough in silica to affect magma viscosity, the character of extrusion, and edifice construction. Stratigraphic relationships between the massif and surrounding deposits suggest that at least some volcanic activities associated with the massif occurred after mare emplacement. Together with volcanic features in the surrounding region, a compositionally and temporally complex volcanic history is supported for this portion of Mare Nubium. Magma production, extrusion, and timing of emplacement models would benefit from petrologic studies of new samples returned from this region. References: [1] Hagerty J.

    Sand massifs in the steppe zone with coarse-textured sandy or loamy sandy soils are mainly characterized by the percolative type of the soil water regime. The annual precipitation penetrating into the groundwater through the aeration zone varies from 80% in the barren sands to 30% and lower in the overgrown sands. The study of the water budget of the Ust'-Kundryuchensk sand massif with an area of 15800 ha indicates that the total volume of the annual groundwater outflow from the massif reaches 10.5 million m3. The water discharged all year round from the sand massif into the Kundryuch'ya and Severskii Donets rivers is fresh and ultrafresh. It contributes to the water discharge of the rivers and desalinates the river water. This is an important nature-protection function of the sand massif.

  14. Two Types of Spatio-Temporal Distribution of Large Earthquakes during Holocene; A Case Study for Active Faults in Island Arc of Northeast Japan

    Northeast Japan is one of the most typical island arc-trench systems which is under EW-trending horizontal compression since ca. 3 Ma-DThe elastic thin layer of upper crust was buckled initially with wavelength of about 50 km, and eventually thrust faults were developed near the inflection line of these crustal folds. The hanging walls have been grown as mountainous regions, while Quaternary sedimentary basins have been formed on the footwalls. Mountain range along the Quaternary volcanic front (Ou Backbone Range) and the uplift zone in the back-arc region (Dewa Hill) are anticlinoriums associated with thrust planes dipping mountain-ward. Kitakami lowland between Kitakami Mountain Ranges (Non-volcanic outer arc) and Ou Backbone Range, Yokote, Yamagata, Nagai, and Yonezawa inter-mountain basins between Ou Backbone Range and Dewa Hill, and Shonai Plain on the west of Dewa Hill are synclinoliums, which have been subsided by the vertical load of hanging walls of thrust faults. There are two types for the relation for the pair of uplifting and subsiding region and thrust faults. One is the case where they are bounded by thrust faults on both sides, for an example, Ou Backbone Range between Kitakami lowland and Yokote inter-mountain basin. Other is the case where thrust faults are developed only on one side, for examples, west-dipping thrust fault zones between Ou Backbone range and Fukushima Basin- Sendai Plain, between Yamagata inter-mountain basin and Dewa Hill, and between Nagai-Yonezawa inter- mountain basins and Dewa Hill. We concentrated our study only on the Holocene events, because it is easier for us to obtain precise data on the timing of seismic events and the amount of vertical displacement per single event. We combined the data from field observations on fault scarplets on the Holocene terraces of different ages with the much data from the previous trench excavation surveys. As a result we found that all these active thrust faults show the recurrence intervals of 2,000 to 4,000 years, and seismic fault slips per single event of 1.5 to 2.0 m, at most 3.5 m. All data on seismic events were plotted on the time-space grids. The resolution of time limit is shorter than 1,000 years. This analysis revealed two types of time-space trends for seismic events. One is concerned with the case where uplift zones are bounded by thrust faults on both sides. We found in this case that large earthquakes with slip of about 2 m occurred alternatively on the two fault zones with time interval of 1,500 to 2,000 years. Other is concerned with the case where one-sided faults between mountainous zones and lowland zones are arranged linearly but discontinuously. Once anyone of the fault segments became active, they tend to have been active nearly simultaneously, probably due to seismic triggering.

    The author has identified the following significant results. Although the limited number of images received did not permit construction of a thermal inertia map, important geological details were obtained in the areas of lithology and tectonics. Interpretation of day, night, and seasonal imagery resulted in differentiating broad calcareous and dolomitic units in the Causse Plateau. In the Massif amoricain, some granite massifs were delineated which were not observed by LANDSAT. Neotectonic faults were also revealed.

  16. Re-Os geochemistry and geochronology of the Ransko gabbro-peridotite massif, Bohemian Massif

    2013-10-01

    The Ransko gabbro-peridotite massif in Eastern Bohemia is a strongly differentiated intrusive complex, which hosts low-grade Ni-Cu ores mainly developed close to the contact of olivine-rich rocks with gabbros, in troctolites, and to a much lesser extent in both pyroxene and olivine gabbros and plagioclase-rich peridotites. Gabbro, troctolite, peridotite and Ni-Cu ores from the Jezírka Ni-Cu (PGE) deposit, considered to be a typical example of the liquid segregation style of mineralization, were analyzed for Re-Os concentrations and isotopic ratios. Seven barren and mineralized samples from the Jezírka deposit yielded a Re-Os regression of 341.5 ± 7.9 Ma (MSWD = 69). Strongly mineralized peridotite with mantle-like initial 187Os/188Os ratio of 0.125 suggests that Os as well as other PGE present in the Ni-Cu mineralization are predominantly of mantle origin. On the other hand, barren and low-mineralized samples have radiogenic initial 187Os/188Os ratios of 0.14-0.16 suggesting some import of Re and/or radiogenic 187Os most likely through contamination by continental crust during magma emplacement. The Re-Os age of the Ransko Massif is significantly younger than the previously suggested Lower Cambrian age, but it is similar to and/or younger than the age of metamorphism of the adjacent Kutná Hora crystalline complex and the Moldanubian unit. Therefore, it is likely that the emplacement of the Ransko massif and its Ni-Cu mineralization was closely connected with the late-stage evolution of the Kutná Hora crystalline complex.

    NASA Astrophysics Data System (ADS)

    Choubert, Georges; Faure-Muret, Anne

    In the Armorican Massif we discovered a stratigraphic and orogenic succession identical to the successions encountered in other countries which we studied for I.G.C.P. Project No. 2. As in Morocco, the regional rejuvenation was most intense during the first Proterozoic orogeny (Lihouides = Sveco-Fenno- Karelides = Hudsonides = Bouazzerides): only the Icartian relicts permit recognition of the importance of the Archaean Basement. Rejuvenation was also very strong during the Pan-Atlantic Thermotectonic Episode. It profoundly modified the ages the two Cadomian belts, which delayed recognition of their true ages and history. Cognécreated the term Pentevrian in 1959 for the ancient basement of the Brioverian. Leutwein (1968) dated it at ca. 1000 Ma, which is in fact the date of its rejuvenation. Its formations have been divided ( Roach et al., 1972) between the Archaean (2500-2700 Ma) and the Lihouian (= Karelian 1900-2000 Ma). Thus, it would be the equivalent of the American Grenvillian which also rejuvenated the Archaean-Hudsonian basement. 1000 Ma is not the age of the first Cadomian orogeny which is well-dated by the Coutances diorite (1300 Ma); it is therefore the age of the second Cadomian belt which was entirely rejuvenated by the Pan-Atlantic Episode. It is known that this last great Precambrian Armorican belt was levelled out by the pre-cover surface dating, also ca. 1000 Ma (Normandy). A redefinition of the Pentevrian would be desirable to avoid misunderstanding.

    Based on research conducted in three Variscan granitoid massifs located within the crystalline Bohemian Massif, the authors confirmed that the higher the degree of their erosional dissection, the smaller the concentration of (222)Rn in groundwaters circulating in these massifs. This notion implies that radon waters and high-radon waters, from which at least some of the dissolved radon should be removed before feeding them as drinking water to the water-supply system, could be expected in granitoid massifs which have been poorly exposed by erosion. At the same time, such massifs must be taken into account as the areas of possible occurrence of radon medicinal waters, which in some countries can be used for balneotherapy in health resorts. Slightly eroded granitoid massifs should be also regarded as very probable radon prone areas or areas of high radon potential. PMID:24657989

    Montserrat Mountain is located near Barcelona in Catalonia, at the north-east corner of Spain, and its massif is formed by conglomerate interleaved by siltstone/sandstone with steep slopes very prone to rock falls. The increasing visitor's number in the monastery area, reaching 2.4 million per year, has pointed out the risk derived from rock falls for this building area and also for the terrestrial accesses, both roads and rack railway. A risk mitigation plan is currently been applied for 2014-2016 that contains monitoring testing and implementation as a key point. The preliminary results of the pilot tests carried out during 2014 are presented, also profiting from previous sparse experiences and data, and combining 4 monitoring techniques under different conditions of continuity in space and time domains, which are: displacement monitoring with Ground-based Synthetic Aperture Radar and characterization at slope scale, with an extremely non uniform atmospheric phase screen because of the stepped topography and atmosphere stratification; Terrestrial Laser Scanner surveys quantifying frequency for unnoticed activity of small rock falls, and monitoring rock block displacements over 1cm; monitoring of rock joints with a wireless net of sensors; and tentative surveying for singular rocky needles with Total Station.

    The Northeast Regional Biomass Program has been in operation for a period of nine years. During this time, state managed programs and technical programs have been conducted covering a wide range of activities primarily aim at the use and applications of wood as a fuel. These activities include: assessments of available biomass resources; surveys to determine what industries, businesses, institutions, and utility companies use wood and wood waste for fuel; and workshops, seminars, and demonstrations to provide technical assistance. In the Northeast, an estimated 6.2 million tons of wood are used in the commercial and industrial sector, where 12.5 million cords are used for residential heating annually. Of this useage, 1504.7 mw of power has been generated from biomass. The use of wood energy products has had substantial employment and income benefits in the region. Although wood and woodwaste have received primary emphasis in the regional program, the use of municipal solid waste has received increased emphasis as an energy source. The energy contribution of biomass will increase as potentia users become more familiar with existing feedstocks, technologies, and applications. The Northeast Regional Biomass Program is designed to support region-specific to overcome near-term barriers to biomass energy use.

    1992-01-01

    More than 50 kg of rock and regolith samples, a little less than half the total Apollo 17 sample mass, was collected from the highland stations at Taurus-Littrow. Twice as much material was collected from the North Massif as from the South Massif and its landslide (the apparent disproportionate collecting at the mare sites is mainly a reflection of the large size of a few individual basalt samples). Descriptions of the collection, documentation, and nature of the samples are given. A comprehensive catalog is currently being produced. Many of the samples have been intensely studied over the last 20 years and some of the rocks have become very familiar and depicted in popular works, particularly the dunite clast (72415), the troctolite sample (76535), and the station 6 boulder samples. Most of the boulder samples have been studied in Consortium mode, and many of the rake samples have received a basic petrological/geochemical characterization.

    Tomtor massif of the largest volcano-plutonic deep alkaline-carbonatite massifs world central type. Area of massif occupy 240 km2 and carbonatites stock is 40 km2. The super large deposit of Nb, TR, Y, Sc, Sr ,REE (Frolov et al. 2001)is found within the massif. The numerical publication are devoted to the ore mineralization there. But the geological struc-ture of the massif and the chemistry of its constituting rocks are not well understood. We obtained new ages based on U-Pb zircon and mica Ar-Ar method (Kotov, Vladykin et al. 2014 Vladykin et al. 2015). The massif was created in 2 stages: 700 and 400 Ma. We (Vla-dykin et al 1998) found rocks of lamproite series and proposed a new scheme of magmatism and the ore.genesis (Vladykin 2007, 2009). Biotite - pyroxenite, peridotite originated in first stage and then intruded iolites, nepheline and alkali syenite. Syenites occupy 70% of -massif and contain 12-13% K2O and 2-4% Na2O showing the K-alkaline-ultramafic nature of Tomtor volcano-plutonic massif (Vladykin 2009). The first stage was accomplished by nelsonitov calcite, dolomite and ankerite carbonatites. Second stage (400Ma) volcanics picrite - lamproite veins and eruptive breccias meli-lite, melanephelinites, tinguaites appered. These rocks are cut by carbonatites of second stage. It was finished by intensive explosive eruption of a silicate (lamproite) tuffs lavobrec-cia kimberlite formed Ebelyakhdiamondiferous placer, melilite rocks in diatremes (feeders), as well as carbonate-phosphate (kamaforite) explosive tuffs with siderite ores. This carbona-tite complex is preserved within the subsidence caldera. Tuff eruption in conjunction with gas and hydrothermal activity determined its rare metal mineralization. These rocks contain to: Nb- 21%, TR-15%, Y-1.5%, Sc-1%, Zr- 0,5% Zn-, Sr-6%, Ti-8%, Ba-4%, V - 8000 ppm, Be- 300 ppm, Ga- 80 ppm, Cr- 1200ppm, Ni- 230 ppm, Mo- 145 ppm, Pb- 4300 ppm, Th- 1500 ppm, U-193 ppm. Picrite - olivine (rare leucite) lamproite and formed volcanic flows, sills, dikes and breccia diatremes having total thickness up to 300 m. (Vladykin, Torbeeva 2005) Lamproites composed of faceted olivine crystals, elongated mica (20 to 50%) and pyroxenes and subor-dinate perovskite, chromite and magnetite. Lamproites are subjected to intense carbona-tion. Leucite lamproites are composed of rounded discharge leucite (substituted by car-bonate) graines, "plastered" by mica secretions and fine pyroxene grains and sometimes sanidines. Phlogopite - annite micas of phlogopite lamproite contains to TiO2 (4-8%) and Cr (up to 1000 ppm). Pyroxenes are diopsides and K prevail in sanidines. There are now Eu anomalies they reveal spectra similar to Australian Ol= lamproites. Isotopic studies (Pokrovsky 2001, Vladykin 2006) indicate mantle originof silicate rocks. and ores excluding secondary redeposition (Vladykin 2009). RFBR grant 15-05-01005.

  13. Geologic Evolution of the Gyala Peri Massif, Southeastern Tibet

    At both the eastern and western terminations of the Himalaya, strong coupling between surface and tectonic processes is manifested in the development of active antiforms in close proximity to large river gorges. In southeastern Tibet the peaks Gyala Peri and Namche Barwa occupy a metamorphic massif that shows remarkable similarities to the Nanga Parbat massif in NW Pakistan, including exposure of high-grade gneisses intruded by Plio-Pleistocene granites. Nanga Parbat has been proposed to constitute a 'tectonic aneurysm' involving erosionally focused strain and related metamorphic reworking. As the Namche Barwa/Gyala Peri massif appears to be quite similar to Nanga Parbat in its geology and geologic setting, we suggest it has a similar origin. Most information to date has been reported from Namche Barwa, with Gyala Peri remaining largely unexplored. Here we report observations from a well-exposed section along the western margin of Gyala Peri. In the west near the Lulang River, a brittle fault zone up to ~1 km wide juxtaposes a metasedimentary/mylonite section on the east against Lhasa/Gandese gneisses and granitoid rocks to the west. The steeply dipping fault zone shows a dominantly east-up (reverse) sense of brittle motion. The lower portion of the Lhasa/Gangdese metamorphic section is cut by dikes of at least two granite phases, a medium-grained Gangdese-like granite, and a leucocratic pegmatite. East of the brittle fault zone, and the metasediments and planar foliated mylonites, there is an ~500 m thick section of S/C mylonites having a dominant reverse and subordinate dextral sense of shear. East of, or possibly in the eastern part of this ductile fault, grey gneisses [presumed basement] are intruded by a syntectonic(?) muscovite granite. Ar-Ar K-feldspar data from Gangdese rocks just west of the brittle fault zone drop to ages of 4 Ma, substantially younger than the pattern seen further to the west at Bayi. Overall, the geology of this section is quite similar to the western margin of the Nanga Parbat massif and, like it, represents progressive displacement and exhumation on a significant thrust sense shear and fault zone bordering the Gyala Peri massif. U-Pb analyses of the granites and the mylonite will be reported along with data from a pilot seismic study that had stations located in proximity to Gyala Peri.

  14. Northeast Pacific flatfish management

    NASA Astrophysics Data System (ADS)

    Trumble, Robert J.

    1998-03-01

    Exploitation of northeast Pacific flatfish effectively began in the late 1800s with the fishery for Pacific halibut. Harvest of other flatfish occurred on a limited, local basis until foreign fishing fleets came to the area in the late 1950s. When US and Canadian fishermen replaced the foreign fleets in the 1970s and 1980s, a conservation-based management system designed to control foreign fishing was applied to the domestic fleet. Flatfish stock assessment is based on scientific surveys, both trawl and longline, and on catch-age models. In Alaskan waters since 1989 and since 1996 in Canadian waters, mandatory observers collect data on species composition, discards of flatfish and other groundfish, and catch and discards of prohibited species. Fishermen pay observer costs. Most biomass and harvest occurs in the Bering Sea-Aleutian Islands area. Many northeast Pacific flatfish are near record-high abundance, an order of magnitude higher than 20 years ago. Exploitation rates based on F35% or F0.1 generate acceptable biological catch of more than 1 million mt, but annual harvest reaches only 300,000 mt. Total groundfish harvest is limited by an optimum yield limit of 2 million mt in the Bering Sea-Aleutian Islands, where the acceptable biological catch is 3 million mt, and by limits on amounts of Pacific halibut and other prohibited species bycatch. Most flatfish are relatively low-value species, and fishermen chose to fish for more valuable species. A large, powerful fleet which developed under open access in the US saw fishing time decline and economic problems increase as catching capacity grew, while Canada stabilized its fleet with limited entry and catch restrictions for individual vessels.

    The article describes the results of petrographic, petrochemical, petrofabric, mineralogical and geochemical studies of the major rock groups potentially Cu, Ni, Pt ore- bearing mafic-ultramafic massifs in the Nizhne- Derbinsk complex (Eastern Sayan Mountains). Based on the data interpretation the investigated massifs can be classified as peridotite- pyroxenite-gabbronorite formation of geosynclinal regime in Altai-Sayan folding area. Significant massif deformation occurred during the final post-consolidation formation stage. The petrographic features of gabbro and petrofabric patterns of the rock-forming minerals in the Burlakski and Nizhne-Derbinsk massifs indicated the fact that massifs were involved in the accretion-collisional development stage of the Central Asian folding belt during the final formation stages the Nizhne-Derbinsk complex.

  16. Tectonic exhumation of the Nanga Parbat massif, northern Pakistan

    NASA Astrophysics Data System (ADS)

    Hubbard, Mary S.; Spencer, David A.; West, David P.

    1995-06-01

    Structural analysis in the Nanga Parbat region of northern Pakistan indicates that extensional deformation has been, in part, responsible for the exhumation of gneissic rocks of the Indian plate basement complex that dominates the Nanga Parbat massif. This massif has been mapped as a syntaxis at the boundary between the Indian and Asian plates in the northwest Himalaya and has received recent attention for evidence of rapid exhumation within the last 10 Ma. Field work along the Main Mantle Thrust (MMT) and within the Indian plate rocks in the area between Babusar Pass and Toshe Gali, southwest of the peak of Nanga Parbat, provided us with evidence from shear fabrics and a shallowly WSW-plunging stretching lineation for a dominant phase of extensional deformation. During this deformation rock of the Kohistan sequence and the Indian plate cover sequence moved to the WSW relative to rocks of the Indian plate basement including the Nanga Parbat gneiss. A post-metamorphic ductile shear fabric pervades the MMT contact, the Indian plate cover sequence below the MMT, but decreases in intensity in the Indian plate basement and the Nanga Parbat gneiss. Using 39Ar/ 40Ar geochronology of hornblendes we have constrained the age of pre-deformational, amphibolite facies metamorphism to be ? 40-56 Ma. Published cooling ages from the Babusar Pass region further document that the extensional deformation was completed by ˜ 20 Ma. We interpret this ductile, extensional shear as the mechanism responsible for significant tectonic exhumation of the gneissic and granitic rocks of the Nanga Parbat massif.

  17. Labrador massif anorthosites: Chasing the liquids and their sources

    NASA Astrophysics Data System (ADS)

    Morse, S. A.

    2006-06-01

    Bulk analyses of plagioclase megacrysts in massif anorthosites contain enough information on the 11 major element oxides of common igneous rocks to retrieve their complete parent magma compositions. The necessary partition coefficients for this inversion process are generated from a core-drilled trapped liquid and a pure anorthosite autolith in the Anorthosite-Norite-Troctolite (ANT) Nain Plutonic Suite (NPS) of Labrador. When applied to plagioclase megacrysts from five anorthositic intrusions in the NPS, the CIPW norms of the derived liquids correctly classify the parent liquids of dark plagioclase as olivine-normative and those of pale plagioclase as quartz-normative. Dark plagioclase megacrysts have higher An, lower K and some tetrahedral ferrous iron, compared to pale megacrysts. Experimental melts considered parental to the Lower Zone troctolites of the Kiglapait Layered Intrusion plot closely among the calculated olivine-normative liquids from the Nain anorthosites, lending further credibility to the inversions. The coupled nature of silica activity and oxygen fugacity for these and other anorthosite magma types permits a classification of massif anorthosites from melatroctolite to andesine norite based on silication and redox state, with potential for quantitative treatment. This treatment may also scale with the degree of crustal contamination experienced by ponded anorthositic magmas. Experimentally determined linear partitioning of plagioclase confirms a narrowing of the binary loop with high pressure, and allows retrieval of one unknown among pressure, temperature and liquid composition. These principles can be used for modeling the plagioclase component of liquids at their source, their intermediate storage sites, during ascent and at emplacement conditions. Experiments on a model Kiglapait bulk composition at high pressure suggest the separation of magma at 11 kbar from a spinel harzburgite source, with crystallization of olivine on ascent to saturation with plagioclase. Ponding of such high-temperature liquids in the lower or middle crust allows assimilation and silication leading to the noritic trend. Felsic suspensions leaving mafic crystals behind can account for anorthosite intrusions at upper levels. Lithospheric extension permits uplift of mantle melting regions to shallower depths, not to be confused with crust, as inferred for the Central North American Rift. Crustal melting appears to be neither necessary nor viable as a source of ANT (perhaps excluding monzonite) magmas. Origins and ideas: The array of anorthosite massifs in eastern North America is of a length scale equal to the volcanic Cameroon Line, which also has a heterogeneous distribution of ages on a very much shorter time scale. Precursor anorthosites far older than the commonly recognized Mesoproterozoic massifs must reflect a deep and revisited root cause of the anorthosite epoch, which may have begun near the time of origin of the Earth's inner core. A tectonically related superplume origin of massif anorthosite magmatism is appealing and has some credibility in paleogeographic reconstructions of Laurentia. It can also explain the apparent Al-Fe-rich nature of the ANT mantle source. The Mg#-An trends of two vastly different layered mafic intrusions, Bushveld and Kiglapait, are uncannily parallel, suggesting a fundamental, scale-independent, physicochemical behavior of large magma systems.

    1973-01-01

    The author has identified the following significant results. Band 5 gives the most information concerning the fracturing in the Massif Central and Parisian Basins. Band 6 and 7 show the fractures emphasized by forest boundaries and by the linear trace of water courses. The most remarkable information drawn from the preliminary investigation of two ERTS-1 images covering two different landscapes, a regular relief of shelving plateau bounded by cuestas having a sedimentary origin and a mountainous region built in crystalline and volcanic rocks, is that the deep structural elements under a thick sedimentary cover can be translated on the surface by indirect criteria. MSS imagery has permitted the Metz fault to be extended towards the west and shows clearly, through land use on the Rhone Valley fluvial deposit, the continuation towards the east of the carboniferous basin of St. Etienne.

  19. Petrogenesis of massif anorthosites: a perspective from St. Urbain, Quebec

    SciTech Connect

    Gromet, L.P.; Dymek, R.F.

    1985-01-01

    The St. Urbain massif is a post-orogenic anorthosite pluton (approx. 500 km/sup 2/) emplaced within the central high-grade granulite terrain of the Grenville structural province. In contrast to other Grenville anorthosites, primary magmatic features are largely preserved. The massif consists predominantly of andesine anorthosite (AA) of remarkable purity containing abundant plagioclase megacrysts. AA has high K/sub 2/O (approx. 2 wgt.%), very high Sr contents (approx. 1200 ppm) and highly fractionated, low REE contents. Features of AA provide the following insights into anorthosite origins: (1) Crystallization from anorthositic magmas, as evidenced by early crystallization of abundant antiperthitic plag, and igneous emplacement of AA dikes and veins into older, unrelated labradorite anorthosite; (2) in situ crystallization of pyroxene after plag, with no direct evidence of earlier crystallization of mafic minerals from a basaltic parent magma; (3) limited differentiation during crystallization, indicated by small variation in plag and opx and limited variations in plag Sr and REE contents; (4) the involvement of water, suggested by the late igneous crystallization of biotite and the localized grain-boundary replacement of plag by calcic myrmekite (An/sub 80/ + qtz). (5) high temperature, relatively oxidizing conditions, indicated by magmatic hemoilmenite +/- rutile and rare ferropseudobrookite in AA and associated ores. AA crystallized from highly feldspathic, relatively oxidized, somewhat hydrous parent magma with little trapped melt. The development of a hyperfeldspathic parent magma with the requisite geochemical features can be ascribed to hydrous partial melting of mafic (to intermediate) rocks at deep crustal or greater depths, leaving a garnetiferous residue.

  20. Serpentinization and Life: Motivations for Drilling the Atlantis Massif

    The Atlantis Massif, located at the intersection of the Atlantis transform fault and the Mid-Atlantic Ridge at 30°N, is one of the best-studied oceanic core complexes (OCCs) and is the target of IODP Expedition 357 late 2015. Drilling will address two exciting discoveries in ridge research: off-axis, serpentinite-hosted hydrothermal activity and carbonate precipitation, exemplified by the Lost City hydrothermal field, and the significance of tectono-magmatic processes in forming heterogeneous and variably serpentinized lithosphere as key components of slow spreading ridges. Serpentinization reactions at moderate- to low-temperatures result in alkaline fluids, characterized by elevated concentrations of abiotic hydrogen, methane and low molecular weight hydrocarbons, and which lead to precipitation of carbonate and brucite upon mixing with seawater. These highly reactive systems have major consequences for lithospheric cooling, global geochemical cycles, carbon sequestration and microbial activity. However, little is known about the nature and distribution of microbial communities in subsurface ultramafic environments and the potential for a hydrogen-based deep biosphere in areas of active serpentinization and fluid circulation. The continuous flux of reduced compounds provides abundant thermodynamic energy to drive chemolithoautotrophy, however, carbon availability may be limited in these high pH environments and represent a challenge for microbial growth. Here we review serpentinization processes as fundamental to understanding the evolution of oceanic lithosphere and discuss open questions related to the impact of serpentinization on the subsurface biosphere. Motivations for drilling the shallow subseafloor of the Atlantis Massif include: (1) exploring the extent and activity of the subsurface biosphere in young ultramafic and mafic seafloor; (2) quantifying the role of serpentinization in driving hydrothermal systems, in sustaining microbiological communities and in the sequestration of carbon in ultramafic rocks; (3) assessing how abiotic and biotic processes change with aging of the lithosphere and with variations in rock type; and (4) characterizing tectono-magmatic processes at OCCs and the evolution of hydrothermal activity associated with detachment faulting.

  6. Geology and Tectonic Evolution of the Kazda? Massif (NW Anatolia)

    Erdo?an, B.; Akay, E.; Hasözbek, A.; Sat?r, M.; Siebel, W.

    In the northwestern part of Anatolia along the Izmir-Ankara Suture Zone, the Kazda? and Uluda? metamorphic massifs form an E-W trending belt between the Sakarya Continent in the north and the Menderes Massif in the south. Internal succession of these two massifs have been described as metamorphic complexes consisting of various kinds of micaschists, quartz mica schist, gneisses, amphibolites and marbles. In the Kazda? metamorphics, metaophiolites have been described additionally (Okay et al., 1991; Yalt?rak and Okay, 1994; Okay et al., 1996; Duru et al., 2004). These metamorphic complexes were considered to form the basement of the Sakarya Continent tectonically overlain by the Early Permian (Topuz et al., 2004) to Late Triassic (Okay and Monie, 1997; Okay et al., 2002) Karakaya Complex. This old basement and the Karakaya Complex were suggested to be unconformably overlain by Liassic and younger platform limestones and detritals (Alt?ner et al., 1991). In the literature, it has also been suggested that the Kazda? Massif had experienced polyphase metamorphism, first during Carboniferous time, second during Early Triassic and third during Tertiary (Bingöl, 1971; Okay et al., 1996; Okay and Sat?r, 2000). In this study we mapped the Kazda? Massif on 1/25000 scale, studied its internal stratigraphy and structures and performed some petrologic analyses and radiogenic age determinations. Stratigraphically in the lower part of the Kazda? metamorphic sequence, there is a part of an oceanic crust represented by metaultramafic rocks and gabbroic metacumulates. Geochemistry of these banded metagabbros show a mid-oceanic affinity. This oceanic crust is overlain, along an unconformity, by a platform type marble succession. At the base of the marbles, there is a basal conglomerate, clasts of which derived from the underlying ultramafic sequence. Thick white marble sequence is overlain along a gradational boundary with a metadetrital succession consisting of quartz mica schist and mica schists that are partly converted into migmatites. There are mafic metavolcanic intervals along the lower gradational zone and within various levels of the metadetrital unit and some marble lenses. The platform sequence resembles to the Mesozoic platform of the Sakarya continent and the underlying oceanic crust might be a part of a Paleotethys Ocean. The Kazda? succession had been subjected to high-grade migmatitic metamorphism accompanied by syntectonic granite emplacements. Zircons of these metagranites yielded U-Pb ages of 27.6 ± 6.8 Ma and 207Pb/206 Pb evaporation ages of 30 Ma. The metadetrital sequences and migmatites show scattered 207Pb/206 Pb zircon evaporation ages ranging from 301.4 ± 2.8 Ma, 274.9 ± 3.1 Ma, 169.3 ± 3.5 Ma indicating mixed ages with strong Alpine imprints. After metamorphism the Kazda? metamorphic sequence was internally imbricated by southward compression and the ultramafic sequence thrust on the top of the platform sequence. During this southward thrusting two different nappes emplaced successively on top of the Kazda? metamorphics from the north. The first nappe consists of a part of Karakaya Complex and the second one, at the top, consists of the Çetmi Melange. Our mapping results clearly show that all these nappe packages including the internally imbricated Kazda? metamorphics are cut by undeformed young granites of 18-24 Ma age (Okay and Sat?r, 2000). Exhumation of the Kazda? metamorphics was a result of the southerly imbrication which occurred after the emplacement of the syntectonic metagranites (29-30 Ma) and before the intrusion of the cross cutting young granites (~ 21 Ma) The present topographic relief of the mountain was the result of younger vertical movements dissipated among numerous E-W trending high angle normal faults observed on its southern slope facing to Edremit Bay.

    2010-05-01

    The samples of peridotites forming the subcontinental lithospheric mantle beneath SW Poland have been brought to the surface by alkaline Cenozoic volcanoes of the Central European Volcanic Province. The area of SW Poland belongs to the Variscan Bohemian Massif. The Cenozoic rifting event formed the Oh?e (Eger) Rift with voluminous volcanic sequences in the NW part of the Massif. Miocene lavas with abundant mantle xenoliths occur in SW Poland at the NE prolongation of the Oh?e Rift (e.g. Ksi?ginki nephelinite). The single ca. 4 - 4.5 My xenolith-bearing eruptions occur to the SE of the Rift (Kozákov and Lutynia basanites), which allows the comparison of lithospheric mantle located outside the rifted area to that located close to the rift, and to asses possible changes in the mantle during the time span of ca 20 My. The mantle peridotites from the Ksi?ginki nephelinite are affected by silicate-melt induced cryptic metasomatism resulting in enrichment of clinopyroxene in light REEs. All of them show similar equilibration temperatures in the range of 1000 - 1100 °C. The pyroxenites of similar TE characteristics, some with well preserved cumulative textures, are common in the Ksi?ginki nephelinites. The composite xenoliths show that pyroxenites form the veins in peridotites. These data suggest that at least part of the lithospheric mantle beneath northern termination of Oh?e Rift was affected by silicate melt metasomatism and thermally rejuvenated, and its lithology was modified by addition of pyroxenitic veins. The modification was contemporaneous with volcanism. The peridotite xenoliths occurring in the 4 Ma Kozákov basanites (Czech Republic, ca 25 km SE from Oh?e Rift margin) yield temperatures of equilibration from 680 to 1065 °C (Christensen et al. 2001). The 4.5 My basanites from Lutynia (SW Poland, ca 170 km ESE from the Oh?e Rift) contain peridotites which equlibrated at 960 to 1000 °C. The clinopyroxenes occurring in these peridotites preserved three different kinds of REE patterns, all LREEs enriched and contain common post-garnet spinel-clinopyroxene symplectites (Matusiak-Ma?ek et al., submitted). These data suggest that the lithospheric mantle occurring outside the Oh?e Rift was also metasomatically modified. However, the record of older events is still preserved and the thermal rejuvenation does not occur in all places. The interpretation of lithospheric mantle structure and lithology based on xenoliths brought to the surface by alkaline lavas is subjected to uncertainties arising from accidental sampling, always representing only the parts of mantle penetrated by the lavas. However, the data presented above suggest that the lithospheric mantle occurring in the area of Oh?e Rift was strongly thermally rejuvenated and lithologically modified during Cenozoic, whereas outside the Rift the scale of rejuvenation and modification was smaller.

  8. Pyroxenites - Melting or Migration?: Evidence from the Balmuccia massif

    NASA Astrophysics Data System (ADS)

    Sossi, Paolo; O'Neill, Hugh

    2014-05-01

    The recognition of pyroxenites in the mantle, combined with their lower solidus temperatures than peridotite, have been proposed as contributors to melting (Pertermann and Hirschmann, 2003; Sobolev et al, 2005; 2007). Geochemical fingerprints of this process invoke an unspecified 'pyroxenite' as the putative source. In reality, mantle pyroxenites are diverse (Downes, 2007), requiring that their mode of origin and compositional variability be addressed. Due to the excellent preservation and exposure of the Balmuccia massif, it has become an archetype for orogenic peridotites, providing information on their composition, field relationships and metamorphic history (Shervais and Mukasa, 1991; Hartmann and Wedepohl, 1993; Rivalenti et al., 1995; Mazzucchelli et al., 2009). The Balmuccia massif consists of fertile lherzolite with subordinate harzburgite and dunite and is riddled with pyroxenite bands, which fall into two suites - Chrome-Diopside (Cr-Di) and Aluminous-Augite (Al-Aug), a pairing present in most massif peridotites. Two-pyroxene thermometry gives temperatures of 850±25°C at 1-1.5 GPa, 500°C lower than asthenospheric mantle at that pressure, meaning they do not preserve their original, high temperature mineralogy. Decimetre-sized Cr-Di bands (?75% CPX, 25% OPX) occur as initially Ol-free and bound by refractory dunite, but, as the bands are rotated into the plane of foliation, they mechanically incorporate olivine. Al-Aug veins (60% CPX, 25% OPX, 15% Sp) discordantly cut the body, intruding lherzolites which show enrichments in Fe, Al and Ti adjacent to the dykes. Both the Cr-Di suite and the Al-Aug series have indistinguishable Sr-, Nd-isotopic compositions to the host peridotite (Mukasa and Shervais, 1999). The major element compositions of pyroxenes in the Cr-Di bands and those in the surrounding peridotites are identical. Together with isotopic evidence, this suggests a local source, not only chemically but spatially, where a very low degree melt (?2%) acts as a transport medium for the pyroxenes and segregates them into dyke-like structures (melt/rock = 0.05-0.1), analogous to 'pressure-solution' creep (Dick and Sinton, 1979). The presence of a melt is required by their REE contents, with moderate La/SmN (0.3 - 0.4) with near-flat HREE (1 < Gd/YbN < 1.1), in contrast to the lherzolites, which preserve highly fractionated La/SmN (0.03 - 0.3) and positively-sloping HREE (0.6 < Gd/YbN < 0.8). Models for their formation as cumulates from a melt are untenable, as, upon decompression, olivine is invariably the first phase to crystallise, thereby drastically reducing Mg# and Cr# to values lower than those in the Cr-Di bands. The Al-Aug veins have lower Mg# (85-87) than the peridotites and Cr-Di series (?90). However, CPXs in both the Al-Aug and the lherzolite preserve REE patterns which are subparallel to, but twice as enriched as those in the normal lherzolites. This characteristic can be explained by focusing of a small, (4%) locally-sourced melt similar to that which transported the Cr-Di pyroxenes. This melt was focused to a melt/rock ratio of 0.6 - 0.7, and crystallised to form the cumulus rocks of the Al-Augite suite. The extreme, heavy ?57Fe values observed in both the pyroxenite and adjacent lherzolite (+ 0.75 per mille) also point to a low-degree melt.

  9. The Subduction of Continental Crust, the Variscan Evolution of the Bohemian Massif, and the Origin of PO Granitoids

    2012-04-01

    Slices of continental crust subducted into the mantle during collisional orogeny may either undergo metamorphism and exhumation towards the surface as coherent slab-like or domal high pressure/ultrahigh pressure (HP/UHP) terranes or, if stalled or delayed in the mantle, melt and return towards the surface as magmas, or undergo a combination of exhumation and melting. Some exhumed HP/UHP terranes contain synorogenic granitoid bodies demonstrating melting does occur during exhumation. Therefore, crust that remains trapped in the mantle will also melt when temperatures reach the appropriate solidi through adiabatic decompression and/or conductive heating and/or radioactive decay. Subducted terranes with hydrous phases will undergo hydrate-breakdown melting and could melt during subduction, when stalled in the mantle or during exhumation. Terranes lacking hydrous phases probably require melting by adiabatic decompression as heated crust becomes ductile and rises as diapirs through the mantle wedge. The generated magmas will intrude through the overlying mantle wedge and into the overlying continental crust to form late orogenic and post orogenic (PO) granitoids depending on the time required to reach solidus temperatures. Geochemical characteristics will depend on P-T conditions, the age/chemistry/mineralogy of the subducted terrane (especially the presence or lack of hydrous phases), and the degree of melt interaction (i.e. the traverse length) with the mantle wedge. Melts that significantly traverse the wedge will acquire the hybrid mantle/crust nature of many PO granitoids. Melts generated by adiabatic decompression close to or within the continental crust will retain ancient crustal signatures. The Variscan evolution of the Bohemian Massif involved two episodes of subduction of continental crust: (1), the southward (present coordinates) subduction of Saxo-Thuringia beneath Bohemia (aka Tapla-Barrandia) along an east-west suture at 400-370 Ma followed by, (2), the east-northeast subduction of Moldanubia beneath Bohemia at 340-320 Ma1. The first subduction was followed by the intrusion of granitoids, including the Central Bohemian Batholith, between 370-340 Ma, all occurring south of the Saxo-Thuringian - Bohemia suture suggesting elements of the subducted Saxo-Thuringian continental crust melted and intruded the overlying Bohemian Craton. The second subduction event was accompanied and followed by multiple intrusions of granites (340 Ma synorogenic granitoids, 340-310 Ma post-orogenic S and high-K granitoids, and 310-290 I-type granitoids2) all occurring west of the of the Moldanubia-Bohemia suture suggesting elements of the subducted Moldanubian crust were melted and intruded the overlying Bohemian/Saxo-Thuringian Craton. Many of the HP/UHP terranes in the Bohemian Massif occur in domal structures suggesting exhumation and melting occurred in part by diapiric upwelling3. It is proposed that both the Saxo-Thuringian and Moldanubian terranes were exhumed by a combination of slab-return and diapiric upwelling and that elements of both terranes were stranded long enough in the mantle to heat up and melt to form most or all of the PO granitoids of the Bohemian Massif. This model involves successive re-distillation of the continental crust and may play a significant role in the evolution of both the continental crust and upper mantle. 1Medaris et al., 2005, Lithos 82. 2Finger et al., 1997, Min & Pet 61. 3Stípská et a., 04, J.

  10. Seismic Anisotropy of The Upper Mantle Beneath The Bohemian Massif

    Vecsey, L.; Plomerovaa, J.; Babuska, V.; Granet, M.

    The study of deep structure of the lithosphere of the Bohemian Massif (BM) by means of seismic anisotropy is based on teleseismic body wave observations and on a joint inversion of anisotropic data (P-residual spheres, the fast shear-wave polarisations and split times). We observe that velocity anomalies are strongly affected by different ori- entations of dipping anisotropic structures within the mantle lithosphere. There are distinct lateral variations of the pattern of P-residual spheres as well as of the split time dt and orientation of the fast shear waves. While in the central part of the BM a large dt and a general E-W orientation of the fast split wave prevail, in the eastern part the dt is smaller and the fast polarisation rotates to the WNW-ESE direction. The mantle lithosphere of the BM appears to consist of at least three domains with dif- ferent orientation of the large-scale fabric. The domains, which we interpret by 3D self-consistent anisotropic models, are separated by sutures cutting the whole litho- sphere. In our research we put special emphasis on the western part of the BM. The region is characterised by the well known earthquake swarms concentrated mainly within the brittle part of the upper crust above the crossing of the deep suture be- tween the Saxothuringian (S) and the Moldanubian (M) with the tectonically active Marianske Lazne (ML) fault. In the mantle lithosphere of both units we observe di- vergently oriented anisotropic structures with typical shear-wave splittings around 1 s or more. Near the deep suture beneath the centre of the swarm near Novy Kostel we observe decreased anisotropy which can be caused by a weakened fabric of the mantle lithosphere. An international seismic field experiment BOHEMA (BOhemian Massif HEterogeneity and Anisotropy) has been running in the region since October 2001. It aims at studying the structure and processes in the crust and upper mantle by means of integrated seismic tomography.

    The Department of Interior Northeast Climate Science Center (NE CSC) is part of a federal network of eight Climate Science Centers created to provide scientific information, tools, and techniques that managers and other parties interested in land, water, wildlife and cultural resources can use to anticipate, monitor, and adapt to climate change. Recognizing the critical threats, unique climate challenges, and expansive and diverse nature of the northeast region, the University of Massachusetts Amherst, College of Menominee Nation, Columbia University, Marine Biological Laboratory, University of Minnesota, University of Missouri Columbia, and University of Wisconsin-Madison have formed a consortium to host the NE CSC. This partnership with the U.S. Geological Survey climate science center network provides wide-reaching expertise, resources, and established professional collaborations in both climate science and natural and cultural resources management. This interdisciplinary approach is needed for successfully meeting the regional needs for climate impact assessment, adaptive management, education, and stakeholder outreach throughout the northeast region. Thus, the NE CSC conducts research, both through its general funds and its annual competitive award process, that responds to the needs of natural resource management partners that exist, in part or whole, within the NE CSC bounds. This domain includes the North Atlantic, Upper Midwest and Great Lakes, Eastern Tallgrass and Big Rivers, and Appalachian Landscape Conservation Cooperatives (LCCs), among other management stakeholders. For example, researchers are developing techniques to monitor tree range dynamics as affected by natural disturbances which can enable adaptation of projected climate impacts; conducting a Designing Sustainable Landscapes project to assess the capability of current and potential future landscapes in the Northeast to provide integral ecosystems and suitable habitat for a suite of representative species and provide guidance for strategic habitat conservation; studying the effects of changes in the frequency and magnitude of drought and stream temperature on brook trout habitats, spatial distribution and population persistence; and conducting assessments of northeastern regional climate projections and high-resolution downscaling.

  17. Occurrence of springs in massifs of crystalline rocks, northern Portugal

    NASA Astrophysics Data System (ADS)

    Pacheco, Fernando António Leal; Alencoão, Ana Maria Pires

    2002-02-01

    An inventory of artesian springs emerging from fractures (fracture springs) was conducted in the Pinhão River Basin and Morais Massif, northern Portugal, comprising an area of approximately 650 km2. Over 1,500 springs were identified and associated with geological domains and fracture sets. Using cross-tabulation analysis, spring distributions by fracture sets were compared among geological environments, and the deviations related to differences in rock structure and, presumably, to differences in deformational histories. The relation between spring frequencies and rock structures was further investigated by spectral determination, the model introduced in this study. Input data are the spring frequencies and fracture lengths in each geological domain, in addition to the angles between fracture strikes and present-day stress-field orientation (?). The model's output includes the so-called intrinsic densities, a parameter indexing spring occurrence to factors such as fracture type and associated deformational regime and age. The highest densities (12.2 springs/km of lineament) were associated with young shear fractures produced by brittle deformation, and the lowest (0.1) with old tensional and ductile fractures. Spectral determination also relates each orientation class to a dominant structural parameter: where spring occurrence is controlled by ?, the class is parallel to the present-day stress-field orientation; where the control is attributed to the length of fractures, the spring occurrence follows the strike of large-scale normal faults crossing the region. Résumé. Un inventaire des sources artésiennes émergeant de fractures (sources de fractures) a été réalisé dans le bassin de la rivière Pinhão et dans le massif de Morais, dans le nord du Portugal, dans une région couvrant environ 650 km2. Plus de 1,500 sources ont été identifiées et associées à des domaines géologiques et à des ensembles de fractures. Grâce à une analyse de tableaux croisés, les distributions des sources par ensemble de fractures ont été comparées aux situations géologiques et aux écarts liés aux différences dans les structures des roches et, probablement, aux différences dans leurs histoires de déformations. Les relations entre la fréquence des sources et la structure des roches ont été étudiées ensuite par détermination spectrale, modèle présenté dans cette étude. Les données d'entrée sont les fréquences des sources et les longueurs des fractures dans chaque domaine géologique, en plus des angles entre directions de fractures et orientation du champ de contraintes actuel (?). La sortie du modèle donne les densités dites intrinsèques, un paramètre indexant l'existence d'une source à des facteurs tels que le type de fracture et le régime et l'âge associés de la déformation. Les densités les plus fortes (12,2 sources par km de linéament) ont été associées à des fractures jeunes produites par des déformations lentes, et les plus faibles (0,1) aux fractures anciennes ductiles et de tension. La détermination spectrale associe également chaque classe d'orientation à un paramètre structural dominant: quand la présence d'une source est contrôlée par ?, la classe est parallèle à l'orientation actuelle du champ de contrainte; lorsque le contrôle est attribué à la longueur des fractures, la présence de sources suit le plan des failles normales à grande échelle traversant la région.

  18. Geomorphological and sedimentological evidences in the Western Massif of Picos de Europa since the Last Glaciation

    The Western Massif of Picos de Europa includes some of the highest peaks of the Cantabrian Mountains. However, the environmental evolution in this massif since the Last Glaciation is still poorly understood. This research provides a new geochronological approach to the sequence of environmental events occurred here since the maximum expansion of glaciers during the last Pleistocene glaciation. The distribution of the glacial landforms suggests four main stages regarding the environmental evolution in the massif: maximum glacial advance, phase of second maximum glacial expansion, Late Glacial and Little Ice Age. A 5.4-m long sedimentological section retrieved from the kame terrace of Belbín, in a mid-height area of the massif, complements the geomorphological interpretation and provides a continuous paleoenvironmental sequence from this area since the Last Glaciation until nowadays. This section suggests that the maximum glacial expansion occurred at a minimum age of 37.2 ka cal BP, significantly prior to the global Last Glacial Maximum. Subsequently, a new glacial expansion occurred around 18.7-22.5 ka cal BP. The melting of the glaciers after this phase generated a shallow lake in the Belbín depression. Lake sediments do not reveal the occurrence of a cold stage during the Late Glacial, whilst, at higher locations, moraine complexes were formed suggesting a glacier readvance. The terrestrification of this lake started at 8 ka cal BP, when Belbín changed to a peaty environment. At 5 ka cal BP human occupation started at the high lands of the massif according to the existence of charcoal particles in the section. The presence of moraines in the highest northern cirques evidences the last phase with formation of small glaciers in the Western Massif of Picos de Europa, corresponding to the Little Ice Age cold event. Since then, the warming climate has led to the melting of these glaciers.

  19. Biodiversity impact of the aeolian periglacial geomorphologic evolution of the Fontainebleau Massif (France)

    NASA Astrophysics Data System (ADS)

    Thiry, M.; Liron, M. N.

    2009-04-01

    Landscape features The geomorphology of the Fontainebleau Massif is noteworthy for its spectacular narrow ridges, up to 10 km long and 0.5 km wide, armored by tightly cemented sandstone lenses and which overhang sandy depressions of about 50m. Denudation of the sandstone pans lead to a highly contrasted landscape, with sandstone ridges ("platières") towering sandy depressions ("vallées") and limestone plateaus ("monts"). This forms the geological frame of the spectacular sceneries of the Fontainebleau Massif (Thiry & Liron, 2007). Nevertheless, there is little know about the erosive processes that have built-up these landscapes. Periglacial processes, and among them aeolian ones, appear significant in the development of the Fontainebleau Massif physiography. The periglacial aeolian geomorphology Dunes and dune fields are known since long and cover about 15% to 25% of the Fontainebleau Massif. The aeolian dunes developed as well on the higher parts of the landscape, as well as in the lower parts of the landscape. The dunes are especially well developed in the whole eastern part of the massif, whereas the western part of the massif is almost devoid of dunes. Nevertheless, detailed mapping shows that dunes can locally be found in the western district, they are of limited extension, restricted to the east facing backslope of outliers. Loamy-sand covers the limestone plateaus of the "monts". The loam cover is of variable thickness: schematically thicker in the central part of the plateaus, where it my reach 3 m; elsewhere it may thin down to 0,20-0,30 m, especially at the plateau edges. Blowout hollows are "negative" morphologies from where the sand has been withdrawed. Often these blowouts are decametric sized and well-delimited structures. Others, more complex structures, are made up of several elongated hectometric hollows relaying each other from and which outline deflation corridor more than 1 km long. A characteristic feature of these blowout hollows is the erosion of the sand beneath the bordering sandstone benches, resulting in overhangs. These structures are the most common in the western district of the Fontainebleau Massif. Ponds develop on the tightly silicified and impermeable sandstone pans that form the "platières". There are permanent ponds and temporary wet zones, formed of interconnected or isolated depressions. The origin of these ponds has to be questioned with regard to the landscape shaping. Their origin is directly bound to the hollowing of uncemented, sandy zones, within the sandstone pans forming the "platières". Erosion by runoff cannot be considered; the only way to hollow them out is by deflation processes. No direct dating of the Quaternary dune and loess deposits of the Fontainebleau Massif exists. Nevertheless, dating of paleopodzols interlayered between drift sands, pond deposits and bones within congelifracts allow relating these periglacial features with the end of the last glacial period. For now, there is no dating to assess what belongs to older glacial periods. Distribution of the aeolian patterns The Fontainebleau Massif displays noteworthy morphological diversities in the various districts of the forest. Some of these differentiations result from geological features, but most of them are related to erosion processes, and among them deflation processes leaved different imprints in the western and eastern districts of the Fontainebleau Massif. The topography played an important role controlling the aeolian processes. Deflation was important in the westerly upwind district. In the westerly front face, aeolian erosion was activated by turbulences around the topographic obstacles. The reliefs funneled the winds and gave rise to swirls that hollow the blowouts. This area displays the sharpest and more chiseled landforms of the massif. Moreover, the sandstone scarps at the edge of the "platières" are high and uncovered, with frequent overhangs. The collapsed sandstone blocks of the "chaos" are im

    The Burpala alkaline massif is a unique geological object. More than 50 Zr, Nb, Ti, Th, Be, and REE minerals have been identified in rare-metal syenite of this massif. Their contents often reach tens of percent, and concentrations of rare elements in rocks are as high as 3.6% REE, 4% Zr, 0.5% Y, 0.5% Nb, 0.5% Th, and 0.1% U. Geological and geochemical data show that all rocks in the Burpala massif are derivatives of alkaline magma initially enriched in rare elements. These rocks vary in composition from shonkinite, melanocratic syenite, nepheline and alkali syenites to alaskite and alkali granite. The extreme products of magma fractionation are rare-metal pegmatites, apatite-fluorite rocks, and carbonatites. The primary melts were related to the enriched EM-2 mantle source. The U-Pb zircon ages of pulaskite (main intrusive phase) and rare-metal syenite (vein phase) are estimated at 294 ± 1 and 283 ± 8 Ma, respectively. The massif was formed as a result of impact of the mantle plume on the active continental margin of the Siberian paleocontinent.

    The Kola geotectonic province in the northeastern Fennoscandian Shield accommodates a significant number of alkaline rock massifs differing in age. They are of mantle and mantle-crustal origin (alkali and nepheline syenites, carbonatites) and related to crustal sources (Neoarchean alkali granites). Among them, the Neoarchean Sakharjok nepheline syenite massif is related to the oldest intrusions of this kind bearing yttrium-zirconium mineralization. The crystallization of alkali syenite pertaining to the first intrusive phase of the intrusive Sakharjok massif is dated to 2645 ± 7 Ma, and this implies that this syenite postdated alkali granites (2.66-2.67 Ga). To date the yttrium-zirconium ore, we applied the local U-Pb method to zircon crystals occurring in the mineralized block hosted in nepheline syenite. The earliest fragments of zircon crystallized 1832 ± 7 Ma ago; the age of metamorphism is estimated at 1784 ± 13 Ma. These dates indicate the Paleoproterozoic age of the yttrium-zirconium mineralization, which was formed as a product of fluid reworking of the Neoarchean nepheline syenite of the Sakharjok massif.

    Nowadays, the increase of the number of seismological stations distributed through- out France, allows a re-evaluation of the regional sismotectonics, in particular by pre- cise localisation and computation of focal mecanisms even for small magnitude earth- quakes (Nicolas et al., 1998, Bethoux et al. 1998, Sue et al., 1999; Baroux et al., 2000; Rigo et al., 1999, Souriau et al.,1998). Thanks to the LDG code "FUSION", we have mixed the bulletin data available from several networks, for the French Central massif and Western France, from January 1962 to October 2001. Then, we have divided our study area in different zones: the western Central Massif, a volcanic province (Chaine des Puys), an eocene graben (Limagne), a sedimentary basin (Bassin de Paris), and also the Charente region and the Armorican massif. Using the VELEST code (Kissling et al., 1994), we have obtain for each of those areas, a minimum 1D model (Kissling et al., 1994) which allows to improve the location of the hypocenters. These new hypocenter distributions are correlated with geological structures, and it is possible to associate swarns of events to faults recognized on the field. Some new focal mecha- nisms are computed. Then, an inversion of focal solutions available for each zone al- lows to deduce the regional stress field. Those informations will allow a re-evaluation of the seismotectonics of the northern Central Massif and Western France. In particu- lar, we propose a qualitative analysis of the major faults activity.

    Radiometric isotope applications in geosciences have been enormously improving during the last decade. Most of these applications were also performed in the entire Turkey by various researchers. From southern to northern part of the Menderes Massif (western Anatolia), 40Ar-39Ar mica; Rb-Sr whole rock, mica; K-Ar whole rock, mica; U-Pb zircon isotope dilution; 207Pb-206Pb single zircon evaporation; apatite, zircon fission tracks, and Th-Pb monazite techniques are commonly applied methods. Most of the age determinations and their interpretations in the Menderes Massif were or are still used to evidence the geodynamic nature of the region with its bordered paleogeography. Last 20 years, nearly, most of the age data in the massif conflict with the well-known stratigraphical and lithological features and still preserve its debate. Moreover, individual age techniques were not properly interpreted or performed within their parameters (closure temperatures, related mineral equilibrium, metamorphic conditions…etc.). Particularly, most popular age determination methods of 40Ar/39Ar mistakenly interpreted as cooling ages instead of neo-crystallization ages. Similarly, Rb-Sr mica ages could easily demonstrate open chemical behavior related to the fluid interactions and present the timing of last fluid circulation events instead of cooling ages. The age data obtained from massif were interpreted without any consideration of the widespread Oligo-Miocene magmatic activity in the northern Menderes Massif, Neogene volcanism, and graben structures in western Anatolia. This study aims to present and summarize new (U-Pb-ID, 207Pb-206Pb single zircon evaporation, Rb-Sr mica) and previously obtained age data from northern and southern Menderes Massif in comparison with literature to better understanding of the age interpretations within their geological limits and related mineral features. Our results in comparison with previously published age data in their detailed stratigraphical features indicate that obtained youngest ages (c.20-25 Ma), which were previously interpreted as the cooling of the massif, are still questionable, and they are more likely representing the timing of fluid circulation events and/or resetting of their related isotopic systems.

  8. Niklas - a Hitherto Unknown Deep Magmatic Massif in the Eastern Mediterranean

    A Niklas massif was discovered recompiling the gravity and magnetic maps and interpreting in 3-D mode all the available data in the area around Eratosthenes Seamount (ESM). The updated datasets clearly show two partially superimposed magnetic dipoles, which also correspond well to disturbances in the gravity field. The pronounced Eratosthenes magnetic anomaly (EMA) is only the positive part of the southeastern dipole. There is no large gravity anomaly here, however the specific gravity pattern corresponds to the magnetic body. The northwestern `magnetic dipole coincides with a prominent (about of 100mGal) gravity high that was recently delineated by Russian geophysicists. Such grav/mag combination allowed us to interpret the anomalies as being caused by a hitherto unknown dense and magnetic body which we have named the Niklas massif. The parameters and depth of causative bodies were calculated by inverse programs and forward modeling using the seismic refraction and reflection constraints. The reliability of the final model was verified using forward modeling. The magnetic data were interpreted by assuming an induced magnetization as the main magnetizing factor. The final model consists of two large compact features oriented NE-SW and located south of the Cyprian arc,as the Eratosthenes and Niklas bodies. The gravity and magnetic pattern of the Niklas is typical for the ophiolite massifs of the Eastern Mediterranean and Southern Turkey (Troodos, Hatay, Antalya). Based on this likeness we assume the Niklas composed by dense and magnetic ophyolites. This large (~100*75km) deep-seated (~7km) thick (~7km) massif is located ~95km southwest of Cyprus. We consider the Niklas as the south-most fragment of the large allochthonous ophiolite thrust slab including the Troodos massif. The tectonic situations of the Niklas area and the central segment of the Cyprian Arc are similar to that of the Eastern Taurus, Bayer-Bassit and Hatay areas. Interaction of the large Late Cretaceous overthrusts, younger Miocene reverse faults inclined mainly to north and Miocene- Pliocene normal faults and strike-slip faults revealed to the existing tectonic pattern. A system of reverse faults of the Cyprian arc separates the Niklas massif from the Troodos. This system is the main reason of the considerably lower level of the Niklas massif relative to the Troodos one. A pronounce tectonic boundary separates probably Niklas area from the Eratosthenes Block. Upper Cretaceous section of this block is sterile of ophiolites suggesting that during the Mesozoic the paleo-Eratosthenes area was located far from present-day position.

    In the SW part of the Anabar shield Th-anomaly was he drilled by ALROSA company by 6 bore holes to a depth of 100 m, which revealed a new Maldzhangarsky rare metal carbonatite massif (Vladykin 2008). It is oval-shaped and elongated NW to SE having dimensions 4.2 x 2.5 km.. and total square ~ 10.5 km2 Carbonatites are from mean- to fine-grained light-colored. Mineral and chemical composition, tracery, dolomite are ankerite and carbonaties. Besides the carbonate it is composed by phlogopite, apatite, alkali amphibole, rarely magnetite and accessory minerals like pyrochlore, zircon, barito-celestine, rare earth carbonates and apatite, reaching 20-30%. In addition to the prevailing carbonatite the carbonatized pyroxenite xenoliths were found in the drilling cores. Geochemical study of the Maldzhangarsky massif carbonatites indicated the presence of significant quantities of typical carbonatite elements- Sr, Ba, Nb, Ta, P, Y, TRE, which is similar to the carbonatites of the Tomtor massif. Many parts of the massif are the ores for Nb, TR, Sr and P. The highest concentrations based on TRE 100 analyses of Nb-8000 ppm, Y-800 ppm; TRE-4%, Sr-10%,. The REE patterns of carbonanites are highly inclined with the r sharp prevalence of light REE on heavy with a rather steep slope., There are now Eu anomalies which is typical for the mantle carbonitetes, and which evidence for the early fractionation of alkaline carbonatite fluid orliquid from silicate melt. Pair correlation of rare earth elements in carbonatite shows their origin from a single source. The intrusive nature of the drilled carbonatites of Maldzhangarsky massif suggest them to be the top part of the unexposed massif. The belonging of this massif to any genetic type is unclear and needs more detail exploration. RBRF grant (15-05-01005). Vladykin N.v.

  10. Crustal structure of the Bohemian Massif in the light of seismic refraction data

    The Bohemian Massif is one of the largest stable outcrops of pre-Permian rocks in Central and Western Europe. It forms the easternmost part of the Variscan Belt, which developed approximately between 500 and 250 Ma during a stage of large-scale crustal convergence, collision of continental plates and microplates, and possibly also subduction. It consists mainly of low- to high-grade metamorphic and plutonic Palaeozoic rocks. The area of the Bohemian Massif can be subdivided into various tectonostratigraphic units separated by faults, shear zones or thrusts trending roughly in a SW-NE direction, and reflecting varying influence of the Cadomian and Variscan orogenies: the Saxothuringian, Teplá-Barrandian, Moldanubian and Moravo-Silesian. Geographically, it comprises the area of the Czech Republic, partly Austria, Germany and Poland. While the post-collisional history of the Variscan Bohemian Massif is relatively clear, the kinematics of plate movements before and during collision is still subject of debates. To investigate such a complex structure, the Bohemian Massif has been covered by a network of seismic experiments as a result of a massive international cooperative effort in central Europe. Detailed analyses of the data from the main profiles of the CELEBRATION 2000, ALP 2002, and SUDETES 2003 refraction and wide-angle reflection seismic experiments show crustal and uppermost mantle structure of the massif and delimit the continuation of various tectonic units in depth. The differences in seismic velocities reflect, to some extent, the structural variances and give some indications for tracing of crust-forming processes during individual tectonic events. Lower crust in the Saxothuringian exhibits complicated structure, ranging from a highly reflective lower crustal layer above Moho with a strong velocity contrast at the top of this layer. Another possible explanation can be a double Moho or the Moho with some lateral topography. This complicated lower crust extends in a depth range of 26-35 km and is characteristic for the Saxothuringian unit, which was subject to the eastward subduction. The Moldanubian in the central part usually seen as the root of the Bohemian Massif is characterized by the deepest (39 km) and the most pronounced Moho within the whole massif with a strong velocity contrast. The lower crust at the eastern margin of the Bohemian Massif is characterized by elevated velocities and high velocity gradient, which seems to be a characteristic feature of the Moravo-Silesian.

    The Pt-Pd and Au-Ag mineralization hosted in both wehrlite without visible links to sulfide mineralization (dispersed assemblage of the Tartai massif) and disseminated Cu-Ni sulfide ore (ore assemblage of the Ognit massif) was found in dunite-wehrlite massifs localized in the fold framework of the Siberian Craton. The Pt minerals in both assemblages comprise sperrylite (PtAs2) and secondary Pt-Fe-Ni alloys in the Ognit massif and Pt-Fe-Cu and Pt-Cu alloys in the Tartai massif. The Pd minerals are widespread in the ore assemblages as compounds with Te, Sb, and Bi, whereas in the dispersed assemblage Pd is concentrated primarily in Pd-Cu-Sb compounds. Both assemblages are characterized by similar substitution of sperrylite with orcelite (Ni5 - xAs2) and then with secondary Pt-Fe-Ni or Pt-Fe-Cu and Pt-Cu alloys; the occurrence of Au-Ag alloys with prevalence of Ag over Au; and replacement of them with auricupride (Cu3Au) at the late stage. Sperrylite in both assemblages contains Ir impurities, while the Pd minerals contain Cu and Ni admixtures, which are typical of mineral assemblages related to the ultramafic intrusions with nickel specialization. PGM were formed under a low sulfur fugacity and high As, Bi, and Sb activities. The postmagmatic fluids affected the primary mineral assemblages under reductive conditions, and this effect resulted in replacement of sperrylite with Ni arsenide (orcelite) and Pt-Fe-Ni and Pt-Fe-Cu alloys; Ni and Cu sulfides were replaced with awaruite and native copper.

  12. Geological setting and petrogenesis of symmetrically zoned, miarolitic granitic pegmatites at Stak Nala, Nanga Parbat - Haramosh Massif, northern Pakistan

    Miarolitic granitic pegmatites in the Stak valley in the northeast part of the Nanga Parbat - Haramosh Massif, in northern Pakistan, locally contain economic quantities of bi- and tricolored tourmaline. The pegmatites form flat-lying sills that range from less than 1 m to more than 3 m thick and show symmetrical internal zonation. A narrow outer or border zone of medium-to coarse-grained oligoclase - K-feldspar - quartz grades inward to a very coarse-grained wall zone characterized by K-feldspar - oligoclase - quartz - schorl tourmaline. Radiating sprays of schorl and flaring megacrysts of K-feldspar (intermediate microcline) point inward, indicating progressive crystallization toward the core. The core zone consists of variable mixtures of blocky K-feldspar (intermediate microcline), oligoclase, quartz, and sparse schorl or elbaite, with local bodies of sodic aplite and miarolitic cavities or "pockets". Minor spessartine-almandine garnet and lo??llingite are disseminated throughout the pegmatite, but were not observed in the pockets. The pockets contain well-formed crystals of albite, quartz, K-feldspar (maximum microcline ?? orthoclase overgrowths), schorl-elbaite tourmaline, muscovite or lepidolite, topaz, and small amounts of other minerals. Elbaite is color-zoned from core to rim: green (Fe2+- and Mn2+-bearing), colorless (Mn2+-bearing), and light pink (trace Mn3+). Within ???10 cm of the pegmatites, the granitic gneiss wallrock is bleached owing to conversion of biotite to muscovite, with local quartz and albite added. Schorl is disseminated through the altered gneiss, and veins of schorl with bleached selvages locally traverse the wallrock up to 1 m from the pegmatite contact. The schorl veins can be traced into the outer part of the wall zone, which suggests that they formed from aqueous fluids derived during early saturation of the pegmatite-forming leucogranitic magma rich in H2O, F, B, and Li. Progressive crystallization resulted in a late-stage sodic magma and abundant aqueous fluids. Two late stages of volatile escape are recognized: the first stage caused pressure-quenching of the last magma, which produced aplite and caused albitization (An3 to An8) of earlier crystallized K-feldspar and oligoclase. The second stage, released during the rupture of miarolitic cavities, produced platy albite ("cleavelandite," An1) locally associated with F-rich moscovite and elbaite. Albitization is likely due to cooling of alkali-fluoride-dominated fluids at less than 2 kbar pressure. The pegmatites are derived from Himalayan leucogranitic magma emplaced prior to 5 Ma into granulitic gneiss that was at 300?? to 550??C and 1.5 to 2 kbar. The pegmatites were emplaced during uplift of the Haramosh Massif, since they cross-cut ductile normal faults but are cut by brittle normal faults. Economically important pink tourmaline mineralization formed in pockets concentrated near the crest of a broad antiform, as a result of trapping of late magmatic aqueous fluids that had become Fe-poor owing to the prior crystallization of schorl.

    The San José district is located in the northwest part of the Deseado massif and hosts a number of epithermal Ag-Au quartz veins of intermediate sulfidation style, including the Huevos Verdes vein system. Veins are hosted by andesitic rocks of the Bajo Pobre Formation and locally by rhyodacitic pyroclastic rocks of the Chon Aike Formation. New 40Ar/39Ar constraints on the age of host rocks and mineralization define Late Jurassic ages of 151.3 ± 0.7 Ma to 144.7 ± 0.1 Ma for volcanic rocks of the Bajo Pobre Formation and of 147.6 ± 1.1 Ma for the Chon Aike Formation. Illite ages of the Huevos Verdes vein system of 140.8 ± 0.2 and 140.5 ± 0.3 Ma are 4 m.y. younger than the volcanic host rock unit. These age dates are among the youngest reported for Jurassic volcanism in the Deseado massif and correlate well with the regional context of magmatic and hydrothermal activity. The Huevos Verdes vein system has a strike length of 2,000 m, with several ore shoots along strike. The vein consists of a pre-ore stage and three main ore stages. Early barren quartz and chalcedony are followed by a mottled quartz stage of coarse saccharoidal quartz with irregular streaks and discontinuous bands of sulfide-rich material. The banded quartz-sulfide stage consists of sulfide-rich bands alternating with bands of quartz and bands of chlorite ± illite. Late-stage sulfide-rich veinlets are associated with kaolinite gangue. Ore minerals are argentite and electrum, together with pyrite, sphalerite, galena, chalcopyrite, minor bornite, covellite, and ruby silver. Wall rock alteration is characterized by narrow (< 3 m) halos of illite and illite/smectite next to veins, grading outward into propylitic alteration. Gangue minerals are dominantly massive quartz intergrown with minor to accessory adularia. Epidote, illite, illite/smectite, and, preferentially at deeper levels, Fe-chlorite gangue indicate near-neutral pH hydrothermal fluids at temperatures of >220°C. Kaolinite occurring with the late sulfide-rich veinlet stage indicates pH < 4 and a temperature of <200°C. The Huevos Verdes system has an overall strike of 325°, dipping on average 65° NE. The orientations of individual ore shoots are controlled by vein strike and intersecting north-northwest-striking faults. We propose a structural model for the time of mineralization of the San José district, consisting of a conjugate shear pair of sinistral north-northwest- and dextral west-northwest-striking faults that correspond to R and R' in the Riedel shear model and that are related to master faults (M) of north-northeast-strike. Veins of 315° strike can be interpreted as nearly pure extensional fractures (T). Variations in vein strike predict an induced sinistral shear component for strike directions of >315°, whereas strike directions of <315° are predicted with an induced dextral strike-slip movement. The components of the structural model appear to be present on a regional scale and are not restricted to the San José district.

    In 1980, the Northeast Planetary Data Center (NEPDC) was established with Tim Mutch as its Director. The Center was originally located in the Sciences Library due to space limitations but moved to the Lincoln Field Building in 1983 where it could serve the Planetary Group and outside visitors more effectively. In 1984 Dr. Peter Schultz moved to Brown University and became its Director after serving in a similar capacity at the Lunar and Planetary Institute since 1976. Debbie Glavin has served as the Data Center Coordinator since 1982. Initially the NEPDC was build around Tim Mutch's research collection of Lunar Orbiter and Mariner 9 images with only partial sets of Apollo and Viking materials. Its collection was broadened and deepened as the Director (PHS) searched for materials to fill in gaps. Two important acquisitions included the transfer of a Viking collection from a previous PI in Tucson and the donation of surplused lunar materials (Apollo) from the USGS/Menlo Park prior to its building being torn down. Later additions included the pipeline of distributed materials such as the Viking photomosaic series and certain Magellan products. Not all materials sent to Brown, however, found their way to the Data Center, e.g., Voyager prints and negatives. In addition to the NEPDC, the planetary research collection is separately maintained in conjunction with past and ongoing mission activities. These materials (e.g., Viking, Magellan, Galileo, MGS mission products) are housed elsewhere and maintained independently from the NEPDC. They are unavailable to other researchers, educators, and general public. Consequently, the NEPDC represents the only generally accessible reference collection for use by researchers, students, faculty, educators, and general public in the Northeast corridor.

  15. Petrology of UHP calcite marble from the Kokchetav Massif

    2004-12-01

    In the Kumdy-kol area, Kokchetav Massif, northern Kazakhstan, three types of UHP marbles have been described: diamond-bearing dolomite marble, Ti-clinohumite-bearing dolomitic marble (Ogasawara et al., 2000) and titanite-bearing calcite marble (Ogasawara et al., 2002). UHP calcite marble is distinguished from other types of UHP marbles by pure calcite (after aragonite) as a dominant carbonate phase. This calcite marble has unique evidence of UHP metamorphism; titanite with coesite exsolution and its precursor compositions indicated that the peak P-T conditions was > 6 GPa and 980-1250 C (Ogasawara et al., 2000; 2002). This rock shows typical granoblastic texture consisting of calcite, diopside, K-feldspar, titanite and symplectite (diopside + zoisite) after garnet. The peak assemblage was aragonite + diopside + K-feldspar + garnet + titanite. Based on the phase relations in the system CaO-MgO-TiO2-SiO2-CO2-H2O, aragonite + diopside + rutile tie-triangle is stable under UHP conditions and divides the compositional space into dolomite-bearing or dolomite-free tetrahedrons (Kikuchi et al., 2003). The presence of titanite in calcite marble means that P-T condition was located at the right-hand side of the reaction rutile + aragonite + coesite = titanite + CO2. Previously described titanite-bearing calcite marble is diamond-free (A-type) and is characterized by titanite with coesite exsolution (Ogasawara et al., 2002). Recently, we found a small amount of diamond in calcite marble (B-type) that is characterized by microdiamond in diopside, and by the lack of K-feldspar and low amount of titanite. No diamond occurs in titanite. Rutile, aragonite and calcite inclusions in titanite were found in titanite of B-type calcite marble. These three inclusion phases in titanite that were confirmed by laser Raman spectroscopy are the evidence for titanite formation reaction described above. This titanite forming reaction occurs at extremely low XCO2 conditions as 0.02. In B-type calcite marble, microdiamond occurs locally and its amount is low; only 61 grains were found in two thin sections. Distributions of titanite, K-feldspar and diamond are heterogeneous and seem to form layers. Diamond occurs in the domain where amounts of titanite and K-feldspar are relatively low. Low amount of microdiamond may be related with extremely low-XCO2 condition under UHP metamorphism. References Ishida et al. (2003: Journal of Metamorphic Geology, Vol. 21, p. 515-522. Kikuchi et al.

  16. Long lasting paleolandscapes stability of the French Massif Central during the Mesozoic

    Regional geodynamical evolution is mainly constrained by the sedimentary record in the basins. Usually, little is known about geodynamics of the peripheral areas and even less on the evolution of the basement areas. Continental unconformities are essential to estimate erosion rates of basement and to model the crustal dynamics that control subsidence of surrounding sedimentary basins but also uplift and erosion on their edges. Dating such unconformities has always been the stumbling block while it is a prerequisite to constrain geodynamical models. Paleomagnetism has been proven as a suitable tool to date ferrugineous paleoweathering features. The method has been applied to paleoweathering occurrences resting on the Massif Central crystalline basement as well as to paleoweathering features affecting the crystalline basement itself. The remanence measurements were obtained at the Paleomagnetic Laboratory of the Institut Physique du Globe de Paris and data analyses were carried out using PaleoMac 5 software (Cogné, 2003). Relative dating of the paleoweathering profiles have been acquired by comparing the recorded paleomagnetic poles from the analysed samples to the apparent polar wandering path of the Eurasian plate (Edel et Duringer, 1997 ; Besse and Courtillot, 2003). Thick red kaolinitic formations rest locally on the Massif Central basement. They are generally bounded by the Tertiary grabens and buried by the Oligocene formations. Thus these azoic red formations have classically been ascribed to the "Siderolithic" formations of Eocene-Oligocene age. They show many pedogenic features (termites burrows, illuviation and hydromorphic features and nodules) and strong relationships with paleolandscape organisation (leaned against fault scarps, infilling paleovalleys, etc.). Macro and micromorphological arrangements show that these formations are in situ paleosols. Paleomagnetic ages range from 160 Ma (Late Jurassic) in the centre of the Massif Central to 140 Ma (Early Cretaceous) in the northern parts of the massif (Ricordel et al., 2005; Ricordel, 2007;). These new ages, fairly older than the expected ones, bring considerable changes in the palaeogeographic evolution of the Massif Central during Mesozoic and Cenozoic. Basement rocks (granites, gneiss, rhyolites and even Permo-Carboniferous sediments) show often pinkish facies throughout the Massif Central. It has been shown that these pink facies are albitised (mainly pseudomorphic replacement of the primary plagioclases into albite and alteration of the biotite into chlorite) (Schmitt, 1992; Parcerisa et al., 2009). These albitised facies are arranged in a clear succession against (?) the Triassic unconformity that gives significant constraints about their development in relation with the Triassic palaeosurface. Secondary albite and chlorite contain minute hematite inclusions, which have been dated, using paleomagnetism, to be Triassic in age (245 Ma) (Ricordel et al., 2007). Given that the alterations are of the same age as the unconformity, it then follows that the albitised facies be related to the Triassic palaeosurface and be used to track back the Triassic palaeosurface through wide crystalline areas, even far away from the Mesozoic cover. Palaeomagnetic analyses allowed dating a large range of paleoweathering features for which no objective datings were previously available. Spatial and temporal distributions of the paleoweathering features and related unconformities provide key arguments to unravel the geodynamic evolution of the Massif Central. ?Triassic, Late Jurassic and Tertiary unconformities are superimposed on large areas of the Massif Centrall. This implies very little erosion of the crystalline basement since Triassic time, as shown by the widespread preservation of the Triassic albitized facies. Since the red kaolinitic paleosols of Late Jurassic/Early Cretaceous age rest directly on the basement rocks, large areas of the Massif Central were uncovered at this period, and more importantly no Jurassic cover was preserved (if such a cover w

    The research of massif state with use of approaches of open system theory [1-3] was developed for investigation the criterions of dissipation regimes for real rock massifs, which are under heavy man-caused influence. For realization of that research we used the data of seismic catalogue of Tashtagol mine. As a result of the analyze of that data we defined character morphology of phase trajectories of massif response, which was locally in time in a stable state: on the phase plane with coordinates released by the massif during the dynamic event energy E and lg(dE/dt) there is a local area as a ball of twisted trajectories and some not great bursts from that ball, which are not greater than 105 joules. In some time intervals that burst can be larger, than 105 joules, achieving 106 joules and yet 109 joules. [3]. Evidently there are two reciprocal depend processes: the energy accumulation in the attracted phase trajectories area and resonance fault of the accumulated energy. But after the fault the system returns again to the same attracted phase trajectories area. For analyzing of the thin structure of the chaotic area we decided to add the method of processing of the seismic monitoring data by new parameters. We shall consider each point of explosion as a source of seismic or deformation waves. Using the kinematic approach of seismic information processing we shall each point of the massif response use as a time point of the first arrival of the deformation wave for calculation of the wave velocity, because additionally we know the coordinates of the fixed response and the coordinates of explosion. The use of additional parameter-velocity of slow deformation wave propagation allowed us with use method of phase diagrams identify their hierarchic structure, which allow us to use that information for modeling and interpretation the propagation seismic and deformation waves in hierarchic structures. It is researched with use of that suggested processing method the thin structure of the chaotic area for two responses of the massif on a high energetic explosion in the northern and southern parts of it. The results are significant for understanding the high energetic rock shock and evaluation a criterion for massif stability estimation.

    The Serbo-Macedonian Massif (SMM) represents a complex crystalline terrane situated between the two diverging branches of the Eastern Mediterranean Alpine orogenic system, the northeast-vergent Carpatho-Balkanides and the southwest-vergent Dinarides and the Hellenides. It is outcropping from the Pannonian basin in the north, to the Agean Sea in the south, along the central and southeastern Serbia, southwestern Bulgaria, eastern Macedonia and southern Greece. It's affiliation to European and/or African plate basement is still questionable due to the lack of reliable geochronological data and a detailed structural investigation. The SMM is the key area for understanding the bipolarity of the Alpine orogenic system, as well as the interaction of the Pannonian and Aegean back-arc extension during the Cenozoic time. The SMM is generally considered to comprise an Upper (low-grade) and a Lower (medium to high-grade) unit (Dimitrijevi?, 1959). The protoliths of both units are reported as volcano-sedimentary successions, which have been later intruded by magmatic rocks during several pulses. On our mission to discern the main magmatic episodes and the geodynamic evolution of the SMM; we have analysed zircon grains of metamorphic rocks from both units, as well as undeformed igneous rocks. LA-ICP-MS analyses were carried out on zircon grains in order to obtain the protolith ages and geochemical analyses were carried out on the total of nineteen samples from different magmatic rocks. Our first results reveal the presence of the Permo-Triassic (253±13 Ma) and a late Variscan magmatism (Carboniferous; 315±9 Ma) in the Serbian part of the SMM; additionally, the Ordovician (490-440 Ma) and the Cadomian (Cambrian; 505 Ma and older) event complete the magmatic evolution in the Serbian part of the SMM. The new geochronological constraints, together with the field relationships, allowed us to conclude: a) The Lower SMM consists of a Cadomian (Ediacaran-early Cambrian) volcano-sedimentary sequences and magmatics, which were intruded by Ordovician magmatic rocks; b) The Upper SMM (Vlasina and Morava unit) contains a volcano-sedimentary sequence, which is intruded by the Cadomian magmatic rocks; c) In contrast to the Lower complex, no Ordovician age magmatics were documented in the Upper unit, and d) Lower and Upper SMM were covered by Silurian-Devonian sedimentary sequence. The youngest magmatic event in the SMM occurred in the late Eocene, it is related to the intrusion of Surdulica granodiorite and subsequent latitic volcanism.

    We identify the lithologic and compositional components of soil 76503 based on INAA of 243 2-4-mm particles and 72 thin sections from these and associated 1-2-mm particles (76502). We present a statistical distribution of the major compositional types as the first step of a detailed comparative study of the North and South Massifs. The soil sample was collected well away from any boulder and is more representative of typical North Massif material than any single large rock or boulder sample. So far, our examination of the 76503 particles has provided a better definition of precursor igneous lithologies and their petrogenetic relationships. It has enabled us to refine the nature of mixing components for the North Massif less than 1-mm fines. It has confirmed the differences in lithologies and their proportions between materials of the North and South Massifs; e.g., the North Massif is distinguished by the absence of a 72275-type KREEP component, the abundance of a highly magnesian igneous component, and the absence of certain types of melt compositions found in the South Massif samples.

    From October 1, 2009 through September 30, 2013 (“contract period”), the Northeast Clean Energy Application Center (“NE-CEAC”) worked in New York and New England (Connecticut, Rhode Island, Vermont, Massachusetts, New Hampshire, and Maine) to create a more robust market for the deployment of clean energy technologies (CETs) including combined heat and power (CHP), district energy systems (DES), and waste heat recovery (WHR) systems through the provision of technical assistance, education and outreach, and strategic market analysis and support for decision-makers. CHP, DES, and WHR can help reduce greenhouse gas emissions, reduce electrical and thermal energy costs, and provide more reliable energy for users throughout the United States. The NE-CEAC’s efforts in the provision of technical assistance, education and outreach, and strategic market analysis and support for decision-makers helped advance the market for CETs in the Northeast thereby helping the region move towards the following outcomes: • Reduction of greenhouse gas emissions and criteria pollutants • Improvements in energy efficiency resulting in lower costs of doing business • Productivity gains in industry and efficiency gains in buildings • Lower regional energy costs • Strengthened energy security • Enhanced consumer choice • Reduced price risks for end-users • Economic development effects keeping more jobs and more income in our regional economy Over the contract period, NE-CEAC provided technical assistance to approximately 56 different potential end-users that were interested in CHP and other CETs for their facility or facilities. Of these 56 potential end-users, five new CHP projects totaling over 60 MW of install capacity became operational during the contract period. The NE-CEAC helped host numerous target market workshops, trainings, and webinars; and NE-CEAC staff delivered presentations at many other workshops and conferences. In total, over 60 different workshops, conferences, webinars, and presentation were hosted or delivered during the contract period. The NE-CEAC also produced publically available educational materials such as CHP project profiles. Finally, the NE-CEAC worked closely with the relevant state agencies involved with CHP development. In New York, the NE-CEAC played an important role in securing and maintaining funding for CHP incentive programs administered by the New York State Energy Research Development Authority. NE-CEAC was also involved in the NYC Mayor's Office DG Collaborative. The NECEAC was also named a strategic resource for the Connecticut Department of Energy and Environmental Protection’s innovative Microgrid Pilot Program.

    The isotopic-geochronological features of thorianite and baddeleyite from carbonatites of the Guli massif, located within Maimecha-Kotui province in the north of the Siberian Platform, are characterized for the first time. The economic complex platinum-group element (PGE) and gold placer deposits are closely related to the Guli massif. Similar geochronological data for thorianite (250.1 ± 2.9 Ma, MSWD = 0.09, n = 36) and baddeleyite (250.8 ± 1.2 Ma, MSWD = 0.2, n = 6) obtained by two different methods indicate that carbonatites were formed close to the Permian-Triassic boundary and are synchronous with tholeiitic flood basalts of the Siberian Platform.

    Boulder 1 from Station 2 at the foot of South Massif is unique in being the only stratified boulder sampled by the Apollo 17 astronauts. Our studies of two of the four specimens that were collected from separate layers show that the boulder is composed of glass-poor, fragment-rich breccias which are aggregates of differentially annealed terra material, mainly ANT, but including basaltic troctolite, pigeonite basalt, granitic particles, dark breccia-rimmed anorthositic clasts, and a KREEPless norite that has not been recognized elsewhere at the Apollo 17 site. The boulder appears to derive from the uppermost blue-gray layer on South Massif, which we believe consists of ejecta deposited from a single large impact event (possibly the one which excavated the Serenitatis Basin).

    This panorama of the region to the northeast of the lander was constructed to support the Sojourner Rover Team's plans to conduct an 'autonomous traverse' to explore the terrain away from the lander after science objectives in the lander vicinity had been met. The large, relatively bright surface in the foreground, about 10 meters (33 feet) from the spacecraft, in this scene is 'Baker's Bench.' The large, elongated rock left of center in the middle distance is 'Zaphod.'

    This view was produced by combining 8 individual 'Superpan' scenes from the left and right eyes of the IMP camera. Each frame consists of 8 individual frames (left eye) and 7 frames (right eye) taken with different color filters that were enlarged by 500% and then co-added using Adobe Photoshop to produce, in effect, a super-resolution panchromatic frame that is sharper than an individual frame would be.

  8. Timing and Style of Deformation in the Floresta Massif, Axial Eastern Cordillera, Colombia

    Saylor, J.; Stockli, D. F.; Mora, A.

    2009-12-01

    The Floresta Massif is one of the largest exposures of Paleozoic and Pre-Cambrian rocks in the Eastern Cordillera. Estimates for the age of onset of shortening-related deformation in the Eastern Cordillera range from late Cretaceous to late Miocene (e.g., Hoorn et al., 1995; Bayona et al., 2008; Parra et al., 2009). The massif is typically interpreted as being exhumed along a high-angle reverse fault (the Soapaga fault) that reactivated Mesozoic extensional structures (e.g., Kammer and Sanchez, 2006). We examined these dual linked issued with new zircon U/Th-He (ZHe) data, new geological mapping and previously published apatite fission track (AFT) data from the Floresta Massif and the associated footwall strata. Previously, an overturned Paleozoic - Cretaceous sequence was mapped emplaced on Tertiary strata along the Soapaga fault. However, new geologic mapping identifies two previously unrecognized thrusts which place, from west to east, Paleozoic strata on Jurassic strata (Fault 3), Jurassic strata on Cretaceous strata (Fault 2) and Cretaceous strata on Tertiary strata (along the previously identified Fault 1). These results are confirmed by AFT and ZHe data. ZHe ages show no resetting in the Tertiary footwall strata, but show partial resetting in the Cretaceous strata and full resetting in the Jurassic and Paleozoic strata. Similarly, AFT data show older ages in the Cretaceous strata than in the Jurassic or Paleozoic strata. Fully reset ZHe ages from Jurassic strata show that exhumation of the Floresta Massif was ongoing by at least the early Oligocene (~ 30 Ma). However, this deformation post-dates an older episode of deformation associated with partially reset ZHe ages in the Cretaceous strata. Based on a decrease in lag time in detrital ZHe data, we infer that the earlier episode of deformation occurred in the mid - late Eocene (45 - 35 Ma).

    The Tartai ultramafic-mafic massif is located in the central part of the East Siberian metallogenic (PGE-Cu-Ni) province (728-712 Ma), which constitutes part of the southern margin of the Siberian craton. This dunite-peridotite-pyroxenite-gabbro massif is the host to low-sulfide PGE-Cu-Ni mineralization. The massif was formed by fractional crystallization of picritic magmas and is composed of wehrlite, dunite, plagiowehrlite, and olivine melanogabbro. The composition of olivine varies from Fo89.9 in dunite to Fo83 in melanocratic olivine gabbro; clinopyroxene is esentially augite. Chrome-spinels crystallized at a low degree of oxidation and have a high iron content. Disseminated sulfide mineralization (pentlandite and heazlewoodite) with high PGE concentrations was identified in wehrlites. Pentlandite is enriched in Fe and Co and depleted in S. These features and the association pentlandite with heazlewoodite suggest that the sulfide mineralization was formed over a wide temperature range (600-400°C) at low sulfur activity (log fS2 from -16 to -9). PGM are represented by Ir-bearing sperrylite, Pd-Cu-Sb panning compounds of variable compositions, Pt-Fe-Cu and Pt-Cu alloys. The evolutionary trend of the ore system was from essentially Ni compositions at the early magmatic stage during formation of disseminated mineralization toward Cu-rich composition at the post-magmatic stage. The PGM assemblage from heavy concentrate haloes differs from bedrock-hosted mineralization in its wider variety of mineral species and the presence of refractory platinoids. Sperrylite from heavy concentrate haloes of the Tartai massif serves as a reliable prospecting guide for bedrock-hosted sulfide Cu-Ni deposits.

    The geochemistry of Hercynian tin-bearing granitoid massifs of the Krušne hory Mts. (Erzgebirge), Slavkovský les Forest (Kaiserwald) and Smr?iny (eastern Fichtelgebirge) is compared by statistical processing of 270 analyses including a wide spectrum of major and trace elements. Seven different types of granites are distinguished. Out of these, five types represent the successive differentiation of the largest massif of NW Bohemia: the Karlovy Vary (Karlsbad) massif. This comprises strongly differentiated peraluminous granites evolving towards extreme Li-Rb-Cs-F-and Sn-enrichment in the youngest members, which are albite-topaz-zinwaldite “lithium” granites. The sixth and seventh types are different from the former by their location in the eastern Krušne hory and tectonic setting, and they display geochemical features of anorogenic granites: they are metaluminous albite-zinwaldite granites with marked enrichment of Nb, Y, and HREE in addition to Li, Rb, Cs, F and Sn, indicating contamination by sub-crustal material. Sn-W mineralizations, including flat peri-contact greisen bodies, steep greisen veins and tourmalinized phyllites, are all intimately associated with the most strongly differentiated granites — the Li-granite and the Cinovec-granite respectively.

  12. Re-Os isotopic evidence for a lower crustal origin of massif-type anorthosites

    Massif-type anorthosites are large igneous complexes of Proterozoic age. They are almost monomineralic, representing vast accumulations of plagioclase with subordinate pyroxene or olivine and Fe-Ti oxides--the 930-Myr-old Rogaland anorthosite province in southwest Norway represents one of the youngest known expressions of such magmatism. The source of the magma and geodynamic setting of massif-type anorthosites remain long-standing controversies in Precambrian geology, with no consensus existing as to the nature of the parental magmas or whether these magmas primarily originate in the Earth's mantle or crust. At present, massif-type anorthosites are believed to have crystallized from either crustally contaminated mantle-derived melts that have fractionated olivine and pyroxenes at depth or primary aluminous gabbroic to jotunitic melts derived from the lower continental crust. Here we report rhenium and osmium isotopic data from the Rogaland anorthosite province that strongly support a lower crustal source for the parental magmas. There is no evidence of significantly older crust in southwest Scandinavia and models invoking crustal contamination of mantle-derived magmas fail to account for the isotopic data from the Rogaland province. Initial osmium and neodymium isotopic values testify to the melting of mafic source rocks in the lower crust with an age of 1,400-1,550 Myr. PMID:10866196

  13. U Pb dating of high temperature metamorphic episodes in the Kon Tum Massif (Vietnam)

    2007-05-01

    In Vietnam, recent studies demonstrated that the Kon Tum Massif was part of the Indosinian mountain system, together with the Truong Son Belt. One sector of the Kon Tum Massif (Song Ba valley) is a granulite facies terrain for which Ar-Ar and U-Pb ages cluster around 245-250 Ma. In the area of Song Bien river, also metamorphosed under granulite facies conditions, Ar-Ar ages of 410 Ma are displayed by biotite. In this study, U-Pb dating of monazite and zircon has been used to understand the reason for these two groups of ages, taking into account the metamorphic mineral assemblages related to granulite facies metamorphism in the two districts. For granulites of Song Ba valley, ages of 245-250 Ma are confirmed from monazites. In the Song Bien district, ages of 465-470 Ma displayed by monazites are interpreted to correspond to the metamorphic climax. Zircons from one of these samples record the age of anatexis that has affected the granulitic rocks. The younger age recorded in the Song Ba valley is considered to reflect high temperature related to charnockitic intrusions emplaced near the end of the Indosinian orogeny, overprinting the earlier formed granulites and resetting the U-Pb and Ar-Ar ages. For the first time, two HT events are dated in the Kon Tum Massif, one occurring during the Ordovician and the other during the Permo-Triassic.

  14. Origin and significance of tourmalinites and tourmaline-bearing rocks of Menderes Massif, western Anatolia, Turkey

    In the western central portion of Anatolia lies the Menderes Massif - a large metamorphic crystalline complex made of Neoproterozoic to Precambrian basement rocks overlain by Palaeozoic to early Tertiary metasedimentary rocks, and with a multistage metamorphic evolution developed from the late Neo-Proterozoic to Eocene. We have undertaken a study of the petrology, geochemistry and boron isotope composition of these tourmaline occurrences aiming to constrain the processes responsible for the enrichment of boron and other fluid mobile elements in the Menderes Massif. The dispersed tourmaline has chemical and boron isotope compositions typical of a continental crust setting, but while some of the tourmalinites display similar signatures, others have heavier boron isotope compositions (up to + 7.5‰). We suggest that the tourmalinites with continental characteristics formed part of the original Pan African basement rocks, whereas those with heavier ?11B signatures formed by later metamorphism during the Alpine orogeny, possibly through interaction with subduction-like fluids. This proposed process may also have been coincident with metasomatism of the lithospheric mantle beneath the massif, which is known to have experienced multistage metasomatism and enrichment history up to Neogene time.

    2015-10-01

    The U-Pb geochronological data on detrital zircons from placers confined to Neoproterozoic quartzite-schist sequences, which are widespread in the Kokchetav massif of northern Kazakhstan, are discussed. Detrital zircons (332 grains in total) originate from the ore occurrences in the central, northern, and western parts of the massif. The concordant ages of detrital zircons from all the examined occurrences largely correspond to intervals of 1017-1528, 1628-1946, and 2653-2739 Ma. The obtained data imply that material of quartzite-schist sequences of the Kokchetav massif was provided by Mesoproterozoic, Paleoproterozoic, and Neoarchean rock complexes. The lower age limit determined for these sequences is approximately 1.06 Ga. The dates obtained for detrital zircons are most consistent with events that took place in Laurentia. They correspond to the formation and breakup of the Columbia/Nuna supercontinent (approximately 1650-1580 and 1450-1380 Ma ago, respectively) and formation of the Rodinia supercontinent in the period of 1300-900 Ma ago.

  16. Mapping of the Ronda peridotite massif (Spain) from AVIRIS spectro-imaging survey: A first attempt

    1993-01-01

    In both AVIRIS and ISM data, through the use of mixing models, geological boundaries of the Ronda massif are identified with respect to the surrounding rocks. We can also yield first-order vegetation maps. ISM and AVIRIS instruments give consistent results. On the basis of endmember fraction images, it is then possible to discard areas highly vegetated or not belonging to the peridotite massif. Within the remaining part of the mosaic, spectro-mixing analysis reveals spectral variations in the peridotite massif between the well-exposed areas. Spatially organized units are depicted, related to differences in the relative depth of the absorption band at 1 micron, and it may be due to a different pyroxene content. At this stage, it is worth noting that, although mineralogical variations observed in the rocks are at a sub-pixel scale for the airborne analysis, we see an emerging spatial pattern in the distribution of spectral variations across the massif which might be prevailingly related to mineralogy. Although it is known from fieldwork that the Ronda peridotite massif exhibits mineralogical variations at local scale in the content of pyroxene, and at regional scale in different mineral facies, ranging from garnet-, to spinel- to plagioclase-lherzolites, no attempt has been done yet to produce a synoptic map relating the two scales of analysis. The present work is a first attempt to reach this objective, though a lot more work is still required. In particular, for the purpose of mineralogical interpretation, it is critical to relate the airborne observation to field work and laboratory spectra of Ronda rocks already obtained, with the use of image endmembers and associated reference endmembers. Also, the pretty rough linear mixing model used here is taken as a 'black-box' process which does not necessarily apply correctly to the physical situation at the sub-pixel level. One may think of using the ground-truth observations bearing on the sub-pixel statistical characteristics (texture, structural pattern, surface distribution and vegetation contribution (grass,..)) to produce a more advanced mixing model, physically appropriate to the geologic and environmental contexts.

  17. Petrology and geochemistry of the Xiugugabu ophiolitic massif, western Yarlung Zangbo suture zone, Tibet

    2011-07-01

    The Yarlung Zangbo Suture Zone (YZSZ), southern Tibet, is a discontinuous belt that is more than 2000 km long, composed of the remnants of Neo-Tethyan Mesozoic ocean. One of these relicts is the Xiugugabu ophiolitic massif which is a mantle thrust sheet of more than 260 km2 overlying the Cretaceous tectonic mélange south of the YZSZ in SW Tibet. The massif is composed of harzburgites and clinopyroxene-harzburgites with porphyroclastic and porphyromylonitic textures. In the southern part of the massif, peridotites were intruded by amphibole-bearing microgabbro and microgabbronorite sills. A diabase unit which is overlaid by a sedimentary sequence crops out on the NE flank of the massif. Mineral chemistry in harzburgites and clinopyroxene-harzburgites indicates compositions similar to abyssal and forearc peridotites. Peridotites are slightly LREE depleted to enriched with [La/Yb]CN 0.06-2.8 and [La/Sm]CN 0.34-2.64. These ultramafic rocks are inferred to be the residues of 5-25% of partial melting of a depleted mantle that has been enriched by percolating metasomatic melts in a suprasubduction environment. Amphibole-microgabbro and amphibole-microgabbronorite sills are mostly composed of brown to green amphibole, calcic plagioclase, clinopyroxene, ilmenite and orthopyroxene in gabbronorite. Textures and compositions of the brown amphiboles indicate a near-solidus high temperature hydrothermal origin (> 800 °C). These intrusive rocks are tholeiitic and show N-MORB type REE patterns ([La/Yb]NC 0.35-0.90), a LILE (mainly Th) enrichment and noticeable Nb, Ta and Ti negative anomalies. They have a suprasubduction affinity and were formed in a back-arc basin setting. The diabase unit outcropping to the NE of the massif is not directly related to the ultramafic and mafic ophiolitic rocks. The diabase shows LREE enriched patterns ([La/Yb]NC 8-8.9) and slight Nb, Ta and Ti negative anomalies. The diabase has an intraplate affinity and could have been derived from a mantle source enriched by subduction-related fluids. The absence of continental crustal assimilation indicates that these rocks were probably emplaced in the Jurassic, in an oceanic environment after the Triassic disaggregation of the Indian plate. The data are consistent with the recent geodynamic model proposed for the central part of the suture for the closure of the Neo-Tethys and suggest that the geodynamic evolution of the western part of the basin was comparable to the central part.

  19. Significance of Geological Units of the Bohemian Massif, Czech Republic, as Seen by Ambient Noise Interferometry

    NASA Astrophysics Data System (ADS)

    R?žek, Bohuslav; Valentová, Lubica; Gallovi?, František

    2015-10-01

    uc(A)bstract Broadband recordings of 88 seismic stations distributed in the Bohemian Massif, Czech Republic, and covering the time period of up to 12 years were processed by a cross-correlation technique. All correlograms were analyzed by a novel approach to get both group and phase dispersion of Rayleigh and Love waves. Individual dispersion curves were averaged in five distinct geological units which constitute the Bohemian Massif (Saxothuringian, Teplá-Barrandean, Sudetes, Moravo-Silesian, and Moldanubian). Estimated error of the averaged dispersion curves are by an order smaller than the inherent variability due to the 3D distribution of seismic velocities within the units. The averaged dispersion data were inverted for 1D layered velocity models including their uncertainty, which are characteristic for each of the geological unit. We found that, overall, the differences between the inverted velocity models are of similar order as the variability inside the geological units, suggesting that the geological specification of the units is not fully reflected into the S-wave propagation velocities on a regional scale. Nevertheless, careful treatment of the dispersion data allowed us to identify some robust characteristics of the area. The vp to vs ratio is anomalously low (~1.6) for all the units. The Moldanubian is the most rigid and most homogeneous part of the Bohemian Massif. Middle crust in the depth range of ~3-15 km is relatively homogeneous across the investigated region, while both uppermost horizon (0-3 km) and lower crust (>15 km) exhibit lower degree of homogeneity.

  20. Subsurface Implications of Spatially Variable Seafloor Character on the Atlantis Massif

    2014-12-01

    We documented and mapped the characteristics of the seafloor on the Atlantis Massif, an ocean core complex located at 30°N on the Mid-Atlantic Ridge. Our goal is to investigate the implications of these surficial features, particularly whether their spatial variations might reflect subsurface lithology and geological processes. We utilized data collected during the MARVEL 2000 cruise AT3-60, specifically Alvin videos and rock samples, Argo II digital still photos, and TOBI/DSL-120 side-scan sonar mosaic. The Alvin dives studied occurred over the Central Dome and Eastern Block, which is interpreted as the hanging wall to the detachment that unroofed the dome. We also studied two Argo II dives located over the Central Dome, one over the Eastern Block, and one over the Western Shoulder of the southern dome. The TOBI/DSL-120 side-scan sonar followed a widespread, looped track providing near total coverage of the massif. We classified the character of the seafloor based on imagery, the acoustic reflectivity, and the basic composition of rock samples. To aid in our classification, we merged Argo II still images to produce photo-mosaics displaying tens of meters long transects. We then classified the seafloor as unconsolidated sediment, lithified sediment (a carbonate crust or cap), exposed bedrock, or rubble. To obtain a broader understanding of the Atlantis Massif, we analyzed the distribution of these classes of seafloor. Over the Central Dome and Western Shoulder, we found most seafloor classes present in notable amounts, with many individual areas dominated by a particular type.

  1. Catalog of Apollo 17 rocks. Volume 1: Stations 2 and 3 (South Massif)

    Ryder, Graham

    1993-01-01

    The Catalog of Apollo 17 Rocks is a set of volumes that characterize each of 334 individually numbered rock samples (79 larger than 100 g) in the Apollo 17 collection, showing what each sample is and what is known about it. Unconsolidated regolith samples are not included. The catalog is intended to be used by both researchers requiring sample allocations and a broad audience interested in Apollo 17 rocks. The volumes are arranged geographically, with separate volumes for the South Massif and Light Mantle, the North Massif, and two volumes for the mare plains. Within each volume, the samples are arranged in numerical order, closely corresponding with the sample collection stations. The present volume, for the South Massif and Light Mantle, describes the 55 individual rock fragments collected at Stations two, two-A, three, and LRV-five. Some were chipped from boulders, others collected as individual rocks, some by raking, and a few by picking from the soil in the processing laboratory. Information on sample collection, petrography, chemistry, stable and radiogenic isotopes, rock surface characteristics, physical properties, and curatorial processing is summarized and referenced as far as it is known up to early 1992. The intention has been to be comprehensive: to include all published studies of any kind that provide information on the sample, as well as some unpublished information. References which are primarily bulk interpretations of existing data or mere lists of samples are not generally included. Foreign language journals were not scrutinized, but little data appears to have been published only in such journals. We have attempted to be consistent in format across all of the volumes, and have used a common reference list that appears in all volumes. Where possible, ages based on Sr and Ar isotopes have been recalculated using the 'new' decay constants recommended by Steiger and Jager; however, in many of the reproduced diagrams the ages correspond with the 'old' decay constants. In this volume, mg' or Mg' = atomic Mg/(Mg +Fe).

    Pelitic and semipelitic anatectic granulites form one of the major lithological units in Kan Nack complex of the Kon Tum massif (in south-central Vietnam), which comprises HT metamorphic and magmatic rocks including granulites and charnockites is classically regarded as the older part of the Gondwana-derived Indosinia terrain. Metamorphic evolution study of pelitic granulite, the most abundant among granulites exposed in this massif, facilitates to understand that tectonic setting take place during the Indosinian time. The paragenetic assemblages, mineral chemistry, thermobarometry and P-T evolution path of pelitic-semipelitic granulites from Kon Tum massif has been studied in detail. Petrographic feature demonstrates that the pelitic granulite experienced prograde history, from pregranulitic conditions in the amphibolite facies up to the peak granulitic assemblages. Successive prograde reactions led to the temperature-climax giving rise to assemblages with cordierite-hercynite and cordierite-hercynite-K-feldspar. Then, as attested by the mineralogic association occurring in cordieritic coronas, these rocks have been affected by retrograde conditions coeval with a decrease of the pressure. Thermobarometic results show that the highest temperature obtained by ksp/pl thermometry is 850 °C and the highest pressure obtained by GASP (Garnet Alumino-Silicate Plagioclase) is 7.8 kbar. The obtained clockwise P-T evolution path involving heating decompression, then nearly isothermal decompression and nearly isobar cooling conditions shows that high temperature-low pressure metamorphism of the studied pelitic anatectic granulites of Kan Nack complex occurred possibly in extensional setting during the Indosinian orogeny of 260-240 Ma in age.

  3. La démocratisation de l'enseignement supérieur au Canada: la face cachée de la massification.

    Kamanzi, Pierre Canisius; Doray, Pierre

    2015-02-01

    The increase in available student placements at colleges and universities, the implementation of provincial and federal postsecondary education policies, and the rise of the educational aspirations of families and individuals have all led to the massification of Canadian higher education. Based on Merle's typology of the forms of democratization, this article attempts to revisit the theory of equality of opportunities by critically analyzing the link between massification of higher education and social equity. The results of an analysis of longitudinal data from the (YIT) Youth in Transition Survey show that at the age of 24 in 2008, approximately 77% of young Canadians have pursued studies in a college or university. If access to postsecondary education is now higher, to what extent has it improved social equity? The article shows, in light of the Merle's typology, that mass university education is achieved in part under the seal of a segregative democratization, while college education tends to be egalitarian. L'augmentation de la capacité d'accueil des collèges et des universités, la mise en œuvre de politiques provinciales et fédérales de développement de l'enseignement postsecondaire et la montée des aspirations scolaires des familles et des individus ont contribué à massifier l'enseignement supérieur canadien. En se basant sur la typologie des formes de démocratisation de Merle, le présent article tente de revisiter la théorie de l'égalité des chances en s'interrogeant sur le lien entre la massification de l'enseignement supérieur et l'équité sociale. Les résultats obtenus à partir de données longitudinales provenant de l'Enquête auprès de jeunes en transition (EJET) montrent qu'à l'âge de 24 ans en 2008, environ 77 % des jeunes Canadiens ont poursuivi des études dans un collège ou une université. Si l'accès aux études postsecondaires est aujourd'hui plus élevé, dans quelle mesure celui-ci a-t-il amélioré l'équité sociale? L'article montre, à la lumière de la typologie de Merle, que la massification de l'enseignement universitaire se réalise en partie sous le sceau d'une démocratisation ségrégative, tandis que l'enseignement collégial a tendance à être égalisateur.

    This study examines the process of deglaciation of the Western Massif of Picos de Europa through field work, geomorphological mapping, sedimentary records and absolute datings of 14C. This massif has several peaks over 2,400 m a.s.l. (Peña Santa de Castilla, 2,596 m; Torre Santa María, 2,486 m; Torre del Mediu, 2,467 m). It is composed mainly by Carboniferous limestones. This area has been intensively affected by karstic dissolution, Quaternary glaciers and fluvio-torrential processes (Miotke, 1968; Moreno et al, 2010; Ruiz-Fernández et al, 2009; Ruiz-Fernández, 2013). At present day, periglacial processes are active at the highest elevations (Ruiz-Fernández, 2013). We have identified four main glacial stages regarding the deglaciation of the massif: (i) maximum advance corresponding to the Last Glaciation, (ii) retreat and stabilization after the maximum advance, (iii) Late Glacial, and (iv) Little Ice Age. Sedimentological studies also contribute data to the understanding of the chronological framework of these environmental changes. The datings of the bottom sediments in two long sequences (8 and 5.4 m) provided a minimum age of 18,075 ± 425 cal BP for the maximum advance stage and 11,150 ± 900 cal BP for retreat and stabilization in the phase following the maximum advance. The ongoing analyses of these sequences at very high resolution will provide new knowledge about the environmental conditions prevailing since the deglaciation of the massif. References Miotke, F.D.

  5. Types Of The Focal Mechanisms Of Seismic Events In The Khibiny Massif

    NASA Astrophysics Data System (ADS)

    Fedotova, I. V.; Yunga, S. L.

    The stress-strain state of Khibiny massif and the focal mechanisms of microseismic events (magnitudes as many M=1) were investigated. This analysis was based on seis- mical data registered by automized monitoring system of in the ore mines "Apatite" as well as on the catalogue of earthquakes registered by Kola regional seismological centre. The main goal of this study is the estimation of applicability of methods of quantitative seismology for a solution of local tasks of prognosis of the dynamic phe- nomena in the ore mines of Khibiny massif during widescale mining operations. On the basis of the existing methods original computer programs were developed. Taking into account features of local monitoring systems of seismicity and collection of the obtained data on focal mechanisms, calculations of matrix of mean "composite" focal mechanisms of the registered seismic events were carried out. The process of grouping of events was based on revealing of similar focal mechanisms. Eigen value analysis of average matrix was performed and the directions of main stresses and tendency of principal deformation directions in the massif are revealed. Thus schema of relative blocks movements is created. As a result of this study 5 basic groups with different types of focal mechanisms of seismic events are selected: normal fault; strike-slip fault (with contraction along the strike of ore bodies), thrust fault, and two interme- diate types - strike-slip with normal movement and strike-slip with upthrust move- ment. Specific structural blocks are revealed on the basis of schema of fault zones and zones of tectonic weakness and analysis of seismic events with the particular focal mechanisms. The directions of main stresses based on the composite focal mecha- nisms well correlates with the directions obtained by other methods. Composite focal mechanisms determined for low magnitude seismic events may be effectively used to control stress-strain state in rock massif, to select configuration of structural blocks restricted by plains of fissures. The researches are executed at support of the Russian foundation for basic research - projects 00-05-64758, 01-05-65340.

  6. The formation conditions of labuntsovite-group minerals in the Kovdor massif, Kola Peninsula

    NASA Astrophysics Data System (ADS)

    Sokolov, S. V.

    2014-12-01

    In the Kovdor massif, labuntsovite-group minerals occur in dolomite carbonatite veins (labuntsovite-Mg), in a natrolite-calcite vein (lemmleinite-Ba and labuntsovite-Fe), and in calcite pockets and veinlets cutting fenites (late labuntsovite-Mg). They are closely intergrown with paragenetic carbonates, and this makes it possible to estimate their crystallization temperature from the fluid inclusions entrapped in dolomite (?265°C) and calcite (175-225°C). The earlier labuntsovite-Mg was formed under relatively acidic conditions, whereas later labuntsovite-calcite mineralization was derived from alkaline solutions.

  7. Geochemical characteristics of rare earth elements in soil of the Ditru Massif, Eastern Carpathians, Romania

    NASA Astrophysics Data System (ADS)

    Ion, Adriana

    2013-04-01

    The present paper describes the level of rare earth elements in soils developed from Ditr?u massif area for evaluating of the background of these elements and accurate assessment of environmental impact. Also this paper contributed to understanding the important role of parent rocks in pedogenic processes. The Ditr?u Alkaline Massif represent an intrusion body with a internal zonal structure, which was emplaced into pre-Alpine metamorphic rocks of the Bucovinian nappe complex close the Neogene - Quaternary volcanic arc of the Calimani-Guurghiu- Harghita Mountain chain. The center of massif was formed by nepheline syenite, which is surrounded by syenite and monazonite. North-western and north-eastern marginal sectors are composed of hornblende gabbro/hornblendite, alkali diorite, monzodiorite, monzosyenites and alkali granite. Small discrete ultramafic bodies (kaersutite-bearing peridotite, olivine, pyroxenite and hornblendite) and alkali gabbros occur in the Jolotca area. All this rocks are cut by late-stage dykes with a large variety of composition including tinguaite, phonolite, nepheline syenite, microsyenite, and aplite. The types of soils predominant in this zone are lithosoils. These soils are shallow developed, have low content in organic matter and reflects mineralogical and geochemical composition of the bedrock. The soil samples were collected from 70 location for all type of representative rocks (approximately 10 soil sampling points for each type of rock). The samples were analyzed by inductively coupled plasma mass spectrometry (ICP-MS). The pH values of these samples varied from 3.6 to 7.3, in general, the soils from massif area are acid or weakly acidic. The pH controls the abundance of REE in soil, the concentration of REE increases with decreasing pH values. In soil samples analyzed the contents of REE follow the order: Ce > La > Nd > Pr > Sm > Eu > Gd > Dy > Yb > Er > Tb > Ho >Tm. ? REE varied from 52.59 ?g g-1 to 579.2 ?g g-1 , the average is 273.14 ?g g-1. The chemical analysis of soil showed an enrichment in LREE (from La to Eu) and a depletion in HREE (from Gd to Lu). Relatively high levels of LREE concentration in soil are genetically associated with REE mineralization. The soil samples developed on the syenite and nephelin syenite are enriched in HREE. The REE chondrite - normalized plots showed for most soils in the sampling area strongly negative anomalies for cerium and europium, positive anomalies for gadolinium and dysprosium. The distribution of REE in soil is given and controlled by the presence of primary minerals (potasic and plagioclase feldspars) and accessory minerals (zircon, monazite, titanite, allanite, apatite, xenotime, thorite, bastnäsite) in bedrock.

    Analysis of digital multispectral MSS-LANDSAT images enhanced through computer techniques and enlarged to a video scale of 1:100.000, show the main geological and structura features of the Pedra Branca granitic massif in Rondonia. These are not observed in aerial photographs or adar images. Field work shows that LANDSAT photogeological units correspond to different facies of granitic rocks in the Pedra Branca massif. Even under the particular characteristics of Amazonia (Tropical Forest, deep weathering, and Quaternary sedimentary covers), an adequate utilization of orbital remote sensing images can be important tools for the orientation of field works.

  10. Origin of mafic and ultramafic cumulates from the Ditr?u Alkaline Massif, Romania

    Mafic-ultramafic cumulates enclosed in gabbroic-dioritic rocks form part of the Mesozoic Ditr?u Alkaline Massif in the Eastern Carpathians, Romania. The poikilitic olivine- and pyroxene-rich and nearly mono mineralic hornblendite rocks display typical cumulate textures with early crystallised olivine (Fo75-73), diopside and augite. In the early stages of their genesis the amphibole was intercumulus whilst in later stages it acquired cumulus status as the fractionating magma evolved. Using major and trace element compositions of minerals and whole-rock samples the origin of these cumulates is determined and the parental magma composition and depth of emplacement are calculated. Cumulus clinopyroxene has more primitive composition than intercumulus amphibole suggesting closed system fractionation for the evolution of poikilitic olivine- and pyroxene-rich cumulates. The evolution of the amphibole-rich mesocumulates is more clearly the result of closed system crystallisation dominated by the precipitation of clinopyroxene and amphibole cumulus crystals. Lamprophyre dykes of the Ditr?u Alkaline Massif are proposed to reflect multiple basanitic parental magma batches from which the cumulus olivine and clinopyroxene crystallised. Relative to these dykes the calculated equilibrium melts for intercumulus amphibole in the cumulates was more primitive whilst that for the cumulus amphibole was more evolved. The calculated crystallisation temperature and pressure of ~ 1000-1050 °C and ~ 0.7 GPa, based on the composition of the amphiboles, indicate crystallisation at lower crustal depths. Rare earth element compositions are consistent with an intra-plate tectonic setting.

  11. Geologic and tectonic setting of Deseado Massif epithermal deposits, Argentina, based on El Dorado-Monserrat

    Echavarría, Leandro E.; Schalamuk, Isidoro B.; Etcheverry, Ricardo O.

    2005-09-01

    Middle-Late Jurassic bimodal volcanism, typical of a retroarc setting, developed during widespread extensional tectonism within the Deseado Massif, southern Argentina. This geologic environment led to the formation of numerous low-sulfidation epithermal deposits that are spatially and temporally related to the volcanic activity. The lack of significant high-sulfidation epithermal deposits may be because the tectonic and volcanic settings do not favor the formation of these types of deposits. El Dorado-Monserrat is a low-sulfidation epithermal prospect located near the southern boundary of the Deseado Massif. Mineralization is genetically linked to the Late Jurassic Chon Aike Formation and hosted by volcanic rocks of the middle Late Jurassic Bajo Pobre Formation. Two different mineralization areas have been identified. The Monserrat area is the most important, with veins hosted in a north-striking, left-lateral shear zone. The average thickness is 0.85 m, and the average metal content is 6.2 ppm gold and 153 ppm silver. The El Dorado area has discontinuous echelon veins within a right-lateral shear zone with low gold and silver grades. Hydrothermal alteration of the host rocks includes an inner zone of quartz-adularia and illite alteration and an outer zone of propylitic alteration. The main gangue mineral is quartz, which formed in successive pulses, plus adularia, pyrite, hematite, magnetite, and barite. Precious metals occur as zoned electrum. Ore mineral precipitation took place between 200 and 280 °C from low salinity fluids due to boiling.

    This study presents laser step-heating 40Ar/39Ar age determinations of basaltic lava samples from Tamu Massif, the oldest and largest edifice of the submarine Shatsky Rise in the northwest Pacific and Earth's proposed largest volcano. The rocks were recovered during Integrated Ocean Drilling Program Expedition 324, which cored 160 m into the igneous basement near the summit of Tamu Massif. The analyzed lavas cover all three major stratigraphic groups penetrated at this site and confirm a Late Jurassic/Early Cretaceous age for the onset of Shatsky Rise volcanism. Lavas analyzed from the lower and middle section of the hole yield plateau ages between 144.4 ± 1.0 and 143.1 ± 3.3 Ma with overlapping analytical errors (2?), whereas a sample from the uppermost lava group produced a significantly younger age of 133.9 ± 2.3 Ma suggesting a late or rejuvenated phase of volcanism. The new geochronological data infer minimum (average) melt production rates of 0.63-0.84 km3/a over a time interval of 3-4 million years consistent with the presence of a mantle plume.

    Northeast India is in deep crisis. It therefore attracts considerable attention from policymakers. Some of the region's problems date from before independence, while others were generated later. The following factors are the root causes of the crisis: massive migration and sharing of the limited resources with poor indigenous people, overexploitation of the environment through extensive deforestation, policymakers' failure to take effective measures to change the economic scenario, and the application of developmental criteria without taking into consideration regional particularities. Migration, health care, environment, human rights, development policy, and nongovernmental organizations in the northeast are discussed. A sustainable development program based upon rural, small-scale industry with markets throughout the country may save the people and environment of the area. PMID:12292121

  16. Geochemistry and petrogenesis of post-collisional ultrapotassic syenites and granites from southernmost Brazil: the Piquiri Syenite Massif.

    The Piquiri Syenite Massif, southernmost Brazil, is part of the post-collisional magmatism related to the Neoproterozoic Brasiliano-Pan-African Orogenic Cycle. The massif is about 12 km in diameter and is composed of syenites, granites, monzonitic rocks and lamprophyres. Diopside-phlogopite, diopside-biotite-augite-calcic-amphibole, are the main ferro-magnesian paragenesis in the syenitic rocks. Syenitic and granitic rocks are co-magmatic and related to an ultrapotassic, silica-saturated magmatism. Their trace element patterns indicate a probable mantle source modified by previous, subduction-related metasomatism. The ultrapotassic granites of this massif were produced by fractional crystallization of syenitic magmas, and may be considered as a particular group of hypersolvus and subsolvus A-type granites. Based upon textural, structural and geochemical data most of the syenitic rocks, particularly the fine-grained types, are considered as crystallized liquids, in spite of the abundance of cumulatic layers, schlieren, and compositional banding. Most of the studied samples are metaluminous, with K2O/Na2O ratios higher than 2. The ultrapotassic syenitic and lamprophyric rocks in the Piquiri massif are interpreted to have been produced from enriched mantle sources, OIB-type, like most of the post-collisional shoshonitic, sodic alkaline and high-K tholeiitic magmatism in southernmost Brazil. The source of the ultrapotassic and lamprophyric magmas is probably the same veined mantle, with abundant phlogopite + apatite + amphibole that reflects a previous subduction-related metasomatism.

  17. Possible petrogenetic associations among igneous components in North Massif soils: Evidence in 2-4 mm soil particles from 76503

    Studies of Apollo 17 highland igneous rocks and clasts in breccias from the North and South Massifs have described magnesian troctolite, norite, anorthositic gabbro, dunite, spinel cataclasites, and granulitic lithologies that may have noritic anothosite or anorthositic norite/gabbro as igneous precursors, and have speculated on possible petrogenetic relationships among these rock types. Mineral compositions and relative proportions of plagioclase and plagioclase-olivine particles in samples 76503 indicate that the precursor lithology of those particles were troctolitic anorthosite, not troctolite. Mineral and chemical compositions of more pyroxene-rich, magnesian breccias and granulites in 76503 indicate that their precursor lithology was anorthositic norite/gabbro. The combination of mineral compositions and whole-rock trace-element compositional trends supports a genetic relationship among these two groups as would result from differentiation of a single pluton. Although highland igneous lithologies in Apollo 17 materials have been described previously, the proportions of different igneous lithologies present in the massifs, their frequency of association, and how they are related are not well known. We consider the proportions of, and associations among, the igneous lithologies found in a North Massif soil, which may represent those of the North Massif or a major part of it.

    The Vercors and Chartreuse Massifs are located at the leading edge of the Western Alps Thrust Belt. They developed in late Miocene-Pliocene times above a major decollement hosted in late Triassic evaporites and/or Liassic marls. The uplift of both massifs led to the oblique and partial inversion of the previous Mesozoic margin of the Southeastern Basin, the thickest onshore sedimentary basin in France. Both massifs are unexplored. The regional geology of eastern France and the results of ten wells located in the near foreland suggest that source rocks are present in late Paleozoic and late Liassic strata, and that fractured sandstones and/or limestones of Triassic/Jurassic age could act as reservoirs. A nonexclusive seismic survey has been shot in 1991 by CGG allowing the first well constrained balanced sections to be drawn across both massifs. They have been used inturn to model the forward kinematics of thrust propagation, and the source rock maturation history, using the {open_quotes}Thrustpack{close_quotes} software developed by IFP and partners.

    The applicability of LANDSAT/MSS images, enhanced by computer derived techniques, as essential tools in mineral research was investigated and the Serra do Mocambo granitic massif was used as illustration. Given the peculiar factors founded in this area, orbital imagery permitted the delineation of potential target areas of mineralization occurrences, associated to albitized/greisenized types. Follow up prospection for primary tin deposits in this granitic massif should be restricted to the delineated areas which are less than 5% of the total superficial area of the massif.

  4. Pyroclastic chronology of the Sancy stratovolcano (Mont-Dore, French Massif Central): New high-precision 40Ar/39Ar constraints

    The Sancy (16 km2) is the youngest of the two stratovolcanoes that constitute the Mont-Dore Massif (Massif Central, France). The restricted number of high precision radio-isotopic ages currently limits our knowledge of the pyroclastic chronology of this edifice which is the source of many tephra layers detected in middle Pleistocene sequences in southeast Europe. To improve our knowledge of the building phases of this stratovolcano, we collected thirteen pyroclastic units covering the entire proximal record. We present 40Ar/39Ar single grain laser dating performed in the facility hosted at the LSCE (Gif-sur-Yvette, France). The 40Ar/39Ar ages range from 1101 ± 11 ka to 392 ± 7 ka (1? external). Four pyroclastic cycles lasting on average 100 ka were identified (C. I to C. IV). C. I corresponds to the earlier explosive phase between 1101 ka and 1000 ka and starts about 100 ka earlier than previously thought. The second pyroclastic cycle (C. II) is the main pyroclastic episode spanning from 818 to 685 ka. This cycle is constituted of a minimum of 8 major pyroclastic eruptions and includes a major event that corresponds to a large plinian eruption at 719 ± 10 ka (1? external) and recorded as a 1.4 m thick layer 60 km south-east of the Sancy volcano. The link between this large eruption and formation of a caldera stays however, hypothetical. The third pyroclastic cycle (C. III) found in the northeastern part of the Sancy (Mont-Dore valley) spanned from 642 to 537 ka. Finally, the youngest pyroclastic cycle (C. IV) starts at 392 ka and probably ends around 280 ka. The age versus geographic location of each pyroclastic cycle indicates three preferential directions of channeling of the pyroclastic events and/or collapse of the volcanic edifice: northwest to west (C. I), southeast (C. II) and finally north to northeast (C. III and IV). The new high precision 40Ar/39Ar age for the Queureuilh bas pyroclastic unit (642 ± 9 ka) is identical within error with the U/Pb age obtained by Cocherie et al. (2009) [Geochimica et Cosmochimica Acta, 73, 1095-1108] and suggests a short residence time of the magma in a shallow, short-lived, small magmatic chamber. Finally, the source of the t21d tephra layer found in the Piànico Séllere varved sequence (Northern Italy) is not the Rivaux pumice flow as proposed by Brauer et al. (2007) [Journal of Quaternary Science 22, 85-96] and neither one of the C. II pyroclastic units as suggested by Roulleau et al. (2009) [Quaternary International 204, 31-43]. Accordingly, the source for the t21d layer has yet to be found at Sancy or elsewhere.

  5. The Front of the Aar Massif: A Crustal-Scale Ramp Anticline?

    The front of the Aar Massif (Swiss Central Alps) is characterized by Paleozoic basement rocks exposed at altitudes of more than 4600m above sea level, followed by a steeply north dipping Mesozoic sedimentary cover and overlying Helvetic nappes. The sediments turn into subhorizontal orientations just few kilometers to the N, where the top of the basement is situated at depths of about 7000m below sea level. What is the origin of this vertical jump of about 12000m of the basement rocks over such short horizontal distances? Recent structural investigations at the Basement-Cover contact indicate a complex structural evolution involving reactivation of extensional faults and inversion of half-grabens during early compressional stages. In the internal parts of the Aar Massif a general steepening of the faults resulted with progressive compression. In the northern frontal part, however, a new spaced cleavage evolved, which is dipping with 20-30° to the SE. In places, the new cleavage in the basement rocks is intense and pervasive and correlates with a steepening of the basement-cover contact and its offsets of several tens to hundreds of meters. Hence strain is strongly partitioned in a large number of high strain zones, which cover a cumulative thickness of at least 2000m, eventually even much more considering subsurface continuation. The Mesozoic sediments affected by this large-scale deformation zone are either intensely ductile folded in the case of limestones or faulted and imbricated in the case of dolomites. These differences in deformation style result from the deformation conditions of about < 250-300°C, where calcite still deforms in a ductile manner, while dolomite and crystalline basement preferentially undergo brittle deformation in combination of dissolution-precipitation processes. In a large-scale point of view, we suggest that the high strain domain in the crystalline basement in fact represents a crustal-scale several kilometers wide shear zone, which passively deforms the sedimentary cover rocks into an embryonic recumbent fold-type structure of several kilometers size. In this sense, the frontal part of the Aar massif represents a thick-skinned ramp anticline structure formed by out of sequence thrusting during a very late stage of Alpine orogeny. The latter point is corroborated by the offset of zircon fission track ages, which yield about 12 Ma suggesting latest activity along the crustal ramp surely later than that time under preferentially brittle to semi-brittle deformation conditions (< 220°C).

  6. Heterogeneous Mantle Fabrics in the Red Hills Ultramafic Massif, South Island, New Zealand

    Field-based investigations of naturally deformed upper mantle section are critical for understanding the spatial scales of mantle heterogeneity. New geologic mapping in the Red Hills Ultramafic Massif, part of the Dun Mountain Ophiolite Belt (south island, New Zealand) confirms a complex history of overprinted domains with heterogeneous structural fabrics. We characterize the extent and style of structures in the along-strike continuation of three previously described structural domains (West-dipping, East-dipping, and Central fabric domains), as well as a newly defined "Motueka" fabric domain. The earliest two fabric domains in the Red Hills are the Central and Motueka Domains. The Central Domain is composed of north-dipping, banded harzburgite, dunite and minor lherzolite. It is overprinted by the younger East-dipping Domain to the east, and abruptly transitions into massive harzburgite to the north. The Motueka Domain is found along the eastern margin of the massif, and is dominated by massive harzburgite and harzburgite with a linear fabric that is subhorizontally plunging and east-west trending. Along the western margin of the Red Hills, a >3 km-thick domain (West-dipping Domain) of roughly 60% dunite and 40% harzburgite has boundaries and foliation oriented N10W/85°W. The intensity of fabric increases toward the west in this domain; concurrently, west-dipping foliations of variable dip rotate into parallelism with the domain boundary. We interpret this zone as a broad shear zone. Variably deformed, late-stage mafic and silicic dikes intrude parts of this shear zone, constraining shear zone activity to ca. 275-285 Ma (cf. Kimbrough et al., 1992). The East-dipping Domain postdates the Western shear zone and is oriented approximately N45E/30SE. Based on structural relationships, we suggest that this domain formed during subsequent strain localization within the adjacent harzburgite-rich rocks of the Central and Motueka Domains, and overprinted earlier fabrics in the dunite-rich rocks of the West-dipping Domain. The East-dipping Domain is truncated by the serpentinized Porter's Fault, a major late-stage normal fault striking N20E/60SE. Kinematic indicators on the Porter's Fault suggest oblique normal movement plunging 37° at 173°. Complex heterogeneous fabrics showing both gradual (West-dipping Domain) and abrupt (East-dipping Domain) localization of mantle deformation are present in the Red Hills. On the basis of previous geochemical work on other parts of the Dun Mountain Ophiolite Belt (Sivell and McCulloch, 2000) and the presence of syn-deformational silicic dikes, we tentatively assign an incipient supra-subduction zone setting during this stage of deformation in the Red Hills Ultramafic Massif.

  7. Geothermobarometry of basaltic glasses from the Tamu Massif, Shatsky Rise oceanic plateau

    We present the results of a petrological study of core samples from Tamu Massif (Site U1347), recovered during the Shatsky Rise Integrated Ocean Drilling Program (IODP) Expedition 324. The basaltic glasses from Site U1347 are evolved tholeiitic basalts containing 5.2-6.8 wt% MgO, and are principally located within the compositional field of mid-ocean ridge basalts (MORBs) but they have systematically higher FeO, lower Al2O3, SiO2, and Na2O concentrations, and the CaO/Al2O3 ratios are among the highest known for MORBs. In this sense, glasses from Site U1347 more closely resemble basaltic magmas from the Ontong Java Plateau (OJP), although they still have lower SiO2 concentrations. In contrast to MORB and similar to OJP, our fractionation corrected values of Na2O and CaO/Al2O3 indicate more than 20% of partial melting of the mantle during the generation of the parental magmas of Tamu Massif. The water contents in the glasses, determined by midinfrared Fourier transform infrared (FTIR) spectroscopy, are MORB-like, and vary between 0.18 and 0.6 wt% H2O. The calculated pressure (P)-temperature (T) conditions at which the natural glasses represent cotectic olivine-plagioclase-clinopyroxene compositions range from 0.1 to 240 MPa and 1100 to 1150°C reflecting magma storage at shallow depth. The variation of the glass compositions and the modeled P-T conditions in correlation with the relative ages indicate that there were at least two different magmatic cycles characterized by variations in eruptive styles (massive flows or pillow lavas), chemical compositions, volatile contents, and preeruptive P-T conditions. Each magmatic cycle represents the progressive differentiation in course of polybaric crystallization after the injection of a more primitive magma batch. Magma crystallization and eruption episodes are followed by magmatic inactivity reflected in the core sequence by a sedimentary layer. Our data for Tamu Massif demonstrate that, similar to Ontong Java ocean Plateau, the crystallization beneath Shatsky Rise occurs at different crustal levels.

  18. Physical-Chemical Factors Affecting the Low Quality of Natural Water in the Khibiny Massif

    NASA Astrophysics Data System (ADS)

    One peculiarity of the Khibiny Massif is its spatial location. Rising over 1000 m above the surrounding hilly land and thus obstructing the passage of air masses, it promotes condensation and accumulation of surface and underground water. Annual precipitation here amounts to 600-700 mm in the valleys and up to 1600 mm on mountainous plateaus. Using this water for drinking and household purposes is problematic due to excess Al and F concentrations and high pH values. Now it is known that in its profile, the Massif is represented by three hydrogeological subzones: the upper (aerated), medium and lower ones. The upper subzone spreads throughout the Massif and is affected by the local drainage network and climatic conditions. The medium subzone is permanently saturated with underground water flowing horizontally to sites of discharge at the level of local river valleys and lakes. The fissure-vein water in the lower subzone is confined to tectonic fractures and faults in the so far underexplored, deeper parts of the Massif. Being abundant, this water ascends under high pressure. At places, water has been observed spurting from as deep as 700 m, and even 960 m. In the latter case, the temperature of ascending water was higher than 18 centigrade (Hydrogeology of the USSR, V. 27, 1971). This work was undertaken to reveal the nature of the low quality of water in the Khibiny by using physical-chemical modeling (software package Selector, Chudnenko, 2010). Processes of surface and underground water formation in the Khibiny were examined within a physical-chemical model (PCM) of the "water-rock-atmosphere-hydrogen" system. In a multi-vessel model used, each vessel represented a geochemical level of the process interpreted as spatiotemporal data - ? (Karpov, 1981). The flow reactor consisted of 4 tanks. In the first tank, water of the Kuniok River (1000 L) interacted with atmosphere and an organic substance. The resulting solution proceeded to tanks 2-4 containing with underlying rocks (100g of each) to interact with them following the preset process level, the water-rock ratio being ? = 1.0; 0.8; 0.6; 0.2 at temperatures (5, 5, 3, 3 centigrade) and pressures (1, 2, 2, 3 bar), respectively. The model had been reliably verified in the aeration zone monitored in the course of the years 2001 and 2010. Analysis of the chemical composition of deeper water-bearing strata has required to increase the intensity of the water-rock interactions in tank 3 (from 0.2 to 0) and tank 4 (from 0 to -0.2) and simultaneously increase the temperature: (5, 10, 10 centigrade) in the third and (10, 18, 25 centigrade) in the fourth. At the value of ?= -0.2 in the temperature range of 18-25 centigrade, the component contents in tank 4 were observed to change (mg/l): Al (8.10-4 -1.10-3), HCO3- (67-69), Na (25-26,9), Cl (6-6,38), F(0.522-0.882) giving rise to new mineral phases, which agreed with the monitoring data of 1996-1997. The pH values in this case were close to 9. Our findings suggest that factors contributing to changing redox conditions, responsible for the formation of soda and abrupt increment of HCO3-, fluorine and aluminum concentrations, are time and temperature.

    The Northern Calcareous Alps cover a large area of the Austrian Alps forming a boundary zone between the Alpine Foreland to the north and the crystalline Central Alps to the south. Generally, climate in this area is more maritime compared to the mountain ranges further south. Few small glaciers are to be found mostly on north-facing slopes. The Northern Calcareous Alps reach maximum elevations of about 3000 m asl. Some of highest summits are to be found are located in the Dachstein Massif reaching 2995 m asl (47° 28' 32? N, 13° 36' 23? E). Occurrence, thickness and thermal regime of permafrost at this mountain massif are widely unknown and knowledge is based on simulations only. In contrast, the glaciation changes at this mountain massif (e.g. Schladminger and Hallstätter glaciers) have been well documented for decades. Within the framework of the research project ROCKING ALPS - dealing with frost weathering and rockfall in alpine regions - knowledge of permafrost distribution in the headwalls surrounding the receding glaciers is substantial to understand rock decay. For this reason, several techniques have been applied in order to detect bedrock permafrost. During the winter of 2012 22 i-buttons (temperature sensors) were attached to rock walls with different orientations but at similar elevations (2600-2700 m asl). Most of these sites were later covered by an insulating winter snow cover therefore allowing the calculation of the base temperature of the winter snow cover (BTS). These BTS data have been used as a first indicator of permafrost presence. In selected rock walls of several mountains in the massif - Koppenkarstein (2863 m asl), Dirndln (2829 m asl) and Gjaidstein (2794 m asl) - additional 2D-geoelectric surveys (five ERT profiles with a length of 100 m and 2 m electrode spacing) were measured in summer 2013. The high resistivities (> 50.000 ohm.m) at about 1.5 m depth and deeper strongly suggest permafrost existence inside the bedrock at all sites. Interestingly, bedrock permafrost was also detected at an immediate glacier margin which has been ice-free for 2-3 decades at maximum. Possibly the glacier at this site was too thin to have a sufficient insulating effect on the rock and hence was cold-based in this position. Alternatively permafrost aggradation occurred rapidly in the few last decades at this site. A new and innovative method in geomorphology and permafrost research is the use of infrared photography. By using this method the gaps between the punctual temperature sensors and the profile lines of the geoelectric measurements can get closed. By using infrared photography it was possible to visualize patterns and amplitudes of the diurnal variations of the surface temperature. First results showed a faster and deeper cooling of the permafrost areas compared to non-permafrost rocks, which is in accordance with the BTS and ERT data.

  1. Mineral compositions of plutonic rocks from the Lewis Hills massif, Bay of Islands ophiolite

    Smith, Susan E.; Elthon, Don

    1988-01-01

    Mineral compositions of residual and cumulate rocks from the Lewis Hills massif of the Bay of Islands ophiolite complex are reported and interpreted in the context of magnetic processes involved in the geochemical evolution of spatially associated diabase dikes. The mineral compositions reflect greater degrees of partial melting than most abyssal peridotites do and appear to represent the most depleted end of abyssal peridotite compositions. Subsolidus equilibration between Cr-Al spinal and olivine generally has occurred at temperatures of 700 to 900 C. The spinel variations agree with the overall fractionation of basaltic magmas producing spinels with progressively lower Cr numbers. The compositions of clinopyroxenes suggest that the fractionation of two different magma series produced the various cumulate rocks.

    We describe for the first time the occurrence of pumpellyite in a miarolitic pegmatite from the monzogranite quarry in Kostrza near Strzegom (Strzegom-Sobótka massif, SW Poland). Unit cell parameters: a = 8.801(1) Å, b = 5.905(1) Å, c = 19.092(1) Å, ? = 97.388(9)°, V = 983.88(35) Å3 and the predominance of Al cations on the X structural site define the mineral as pumpellyite-(Al). Both divalent and trivalent iron is present in the structure and Fe2+/Fe3+ is 88:12. Intracrystalline partitioning of ferric and ferrous iron is discussed. The pumpellyite probably crystallized within the temperature range 200-150°C.

  3. Permeability Structure Beneath the Lost City Hydrothermal Field, Atlantis Massif Oceanic Core Complex

    NASA Astrophysics Data System (ADS)

    McCaig, A. M.; Titarenko, S.

    2012-12-01

    The Lost City Hydrothermal Field (LCHF) has been venting low temperature (50-90 °C) alkaline fluids for at least 120,000 years. It is located close to the crest of the transform wall of the Atlantis Massif (30 °N, MAR), and is underlain by detachment fault schists and serpentinized peridotites with minor gabbro. Only 5km to the north, IODP Hole 1309D sampled 1400 m of gabbroic rocks. An almost linear thermal gradient of ~100 °C/km has recently been measured in the Hole during IODP expedition 340T, a unique piece of data in young ocean crust. The combination of a steep conductive gradient in proximity to a long lived hydrothermal system places severe constraints on the permeability structure of the Massif. We have used Comsol Multiphysics to create the first 2-D topographic model of the LCHF using a N-S profile through the vent site and Hole 1309D. Initial models use a constant basal heat flow (0.2 W/m2) which produces a steady state conductive gradient of about 85 °C/km using temperature-dependent conductivity and heat capacity. We include a low permeability basal layer and in some models a lower permeability zone beneath the IODP Hole with a boundary dipping steeply southwards, corresponding to a boundary between gabbro and serpentinite inferred from seismic tomography. We have used two top boundary conditions; (1) a mixed boundary condition in which dT/dz =0 if flow is upwards, and T=0 if flow is downwards, and (2) T=0. The first boundary condition is normally used in hydrothermal modelling but produces serious vent temperature artifacts at low upward flow rates since heat cannot escape conductively. The second boundary condition produces more stable models and has been shown by Wilcock (1998) to reproduce the form of hydrothermal circulation accurately. However vent temperatures can only be approximated due to the upper thermal boundary layer produced. With a constant permeability in the upper part of the model, transient high temperature vents form near the highest point of the topography but migrate with time across the location of the borehole, where a conductive gradient is never established. Conditions in the Massif are much better reproduced by models with a lower permeability zone beneath the IODP borehole. This stabilises the vent location near the crest of the Massif, and creates a conductive gradient in the borehole which typically increases gradually with time up to about 400000 years. Transient high temperature venting (with unstable flow at permeabilities <10-15 m2) are succeeded by stable venting with gradually declining vent temperatures matching Lost City temperatures over significant time intervals. In all our models, seafloor topography strongly influences circulation with influx of fluid in the transform valley (where microbes could potentially live several km below the seafloor) and discharge in higher topography. The requirement of a particular permeability structure means that long-term vent sites similar to Lost City may be a relatively uncommon occurrence in the world's oceans.

  9. Proterozoic massif anorthosites and related rocks in Labrador: the anorthosite-charnockite connection

    SciTech Connect

    Emslie, R.F.

    1985-01-01

    Massif anorthosites of Labrador are closely associated in space and time with voluminous, felsic, fayalite- and ferrous pyroxene-bearing igneous rocks. These include charnockites, monzonites, biotite-hornblende granites, and locally syenites. Igneous charnockites form major parts of some of the granitic complexes. In Mistastin batholith for example, charnockitic assemblages comprise about 35% of a total area of 6500 sq. km. Feldspar pairs and coexisting fayalite-opx-qtz in these rocks indicate P and T near 3.5 kb, 750/sup 0/C, assumed to represent near solidus equilibration. Diorites and monzonites intruded by charnockite have mesoperthites implying crystallization T>900/sup 0/C presumably recording earlier stages of crystallization. Oxide and silicate assemblages indicate redox conditions between FMQ and WM oxygen buffers and water pressures well below Ptotal. Younger biotite-hornblende granites and quartz syenites lack Ti-mt. but retain fayalite suggesting that magmatic crystallization was largely closed to water and oxygen. Initial Sr isotope ratios in charnockite-granite suites of central labrador support derivation of the magmas largely or entirely from crustal source rocks. Compositions of mafic silicates and plagioclase, associated Fe-Ti oxide concentrations, trace elements and Sr isotopes in massif anorthosites are in accord with the rocks being crystallization products of substantially fractionated, originally more mafic, mantle magmas. Close association of high temperature, water-poor, reduced crustal melts is consistent with a fusion process in which heat supply and oxygen buffering were controlled by fractional crystallization of a substantial body of mafic magma subjacent to continental crust.

  10. Homogeneous /sup 18/O enrichment of the Marcy Anorthosite Massif, Adirondack Mountains, New York

    Morrison, J.; Valley, J.W.

    1985-01-01

    The Marcy Anorthosite Massif in the Adirondack Mountains, New York, is a composite intrusion that was metamorphosed to granulite facies at approx. 1.1 Ga. The massif is dominantly anorthosite but ranges from anorthosite (1-10% mafics) to oxide-rich pyroxenite layers (up to 98% mafics). In the St Regis Quad (SRQ) systematic variations in the percentage of mafics (POM) roughly parallel the foliation and increase toward the contacts (Davis, 1971). In 47 SRQ samples studied the POM varies from 2-25%; garnet ranges from 0-11%, pyroxene from <1-16% and oxides from <1-8%. Percent phenocrysts varies between 1-80. The Port Kent-Westport Unit (PKW) and an associated hybrid unit show significantly greater textural variability. The POM Varies from 1-50%; garnet ranges from 0-18%, pyroxene from 0-15%, oxides from 0-3% and phenocrysts vary from 0-80%. A total of 28 unaltered plagioclase phenocrysts have been analyzed for delta/sup 18/O: in 13 SRQ samples delta/sup 18/O = 9.0-9.8 (x=9.4. sigma=0.2) and in 15 samples from the PKW and hybrid units values of delta/sup 18/O=8.5-10.5 (x=9.5.sigma0.5). No correlations exist between the modal parameters and delta/sup 18/O. The results from SRQ demonstrate an extreme homogeneity suggesting for the first time a pristine magmatic character which is supported by the virtual absence of metasedimentary inclusions. This contrasts with PKW where inclusions are common and delta/sup 18/O values are more heterogeneous. Further analyses will evaluate the possibility of an anomalous source region as a cause of the /sup 18/O enrichment in the anorthosite.

  11. Fluid Evolution in the Nepheline Syenites of the Ditrau Alkaline Massif, Romania

    NASA Astrophysics Data System (ADS)

    Fall, A.; Bodnar, R. J.; Szabo, C.

    2004-12-01

    The Ditrau Alkaline Massif (Romania) is situated in the central part of the Eastern Carpathians, as an intrusion in the Bukovina nappe system of the Mesozoic crystalline zone. Nepheline syenites are the most abundant rocks occurring in the central and eastern part of the Massif, and representing the youngest intrusion of the complex. The nepheline syenite is composed of perthitic feldspars, nepheline, biotite, amphibole, pyroxene and titanite as primary minerals, and sodalite, cancrinite, calcite, analcite as secondary minerals formed at the expense of nepheline. Petrographic observations and fluid inclusion studies were performed on nepheline syenites in order to examine the effect of residual magmatic fluids on the alteration of nepheline to secondary minerals listed above. The alteration of nepheline to secondary minerals is obvious from textural relationships and comparison of the compositions of the minerals. Fluid inclusion studies provide evidence for the role of highly saline fluids in the incongruent transformation reactions (nepheline to sodalite and/or cancrinite and/or analcite). The fluids, in most cases, can be modeled by the H2O-NaCl system with various NaCl contents; however inclusions with more complex fluid (containing also K, Ca, CO3, etc. besides H2O and NaCl) composition are abundant in the nepheline. The alteration process is supported by the presence of fluid inclusions in cancrinite, showing lower salinity compared to those in nepheline. During the crystallization period of the nepheline syenites the rock was in equilibrium with a salty solution whose salinity increased with time, mostly by the loss of H2O to produce H2O-bearing minerals like amphiboles and micas. One possible interpretation of the fluid inclusions and textural observations is that nepheline alteration to sodalite, cancrinite and analcite was associated with increasing salinity of the fluids with time.

  12. Fluid evolution in the nepheline syenites of the Ditr?u Alkaline Massif, Transylvania, Romania

    2007-05-01

    The Ditr?u Alkaline Massif is an intrusion into the Bucovina nappe system that is part of the Mesozoic crystalline zone located in Transylvania, Romania, in the Eastern Carpathians. Nepheline syenites are the most abundant rocks in the central and eastern part of the Massif, and represent the last major intrusion of the complex. Fluid inclusions in nepheline, aegirine and albite were trapped at magmatic conditions on or below the H 2O-saturated nepheline syenite solidus at about 400-600 °C and 2.5-5 kbars. Early nepheline, and to a lesser extent albite, were altered by highly saline fluids to produce cancrinite, sodalite and analcime, during this process cancrinite also trapped fluid inclusions. The fluids, in most cases, can be modeled by the H 2O-NaCl system with varying salinity; however inclusions with more complex fluid composition (containing K, Ca, CO 3, etc., in addition to NaCl) are common. Raman spectroscopic analyses of daughter minerals confirm the presence of alkali-carbonate fluids in some of the earliest inclusions in nepheline, aegirine and albite. During crystallization, the melts exsolved a high salinity, carbonate-rich magmatic fluid that evolved to lower salinity as crystallization progressed. Phases that occur early in the paragenesis contain high-salinity inclusions while late phases contain low-salinity inclusions. The salinity trend is consistent with experimental data for the partitioning of chlorine between silicic melt and exsolved aqueous fluid at about 2.0 kbars. The activity of water ( aH 2O ) in the melt increases during crystallization, resulting in the formation of hydrous phases during late-stage crystallization of the nepheline syenites.

  13. Volcanic evolution of the submarine super volcano, Tamu Massif of Shatsky Rise: New insights from Formation MicroScanner logging imagery

    2015-01-01

    Massif, the southernmost plateau of Shatsky Rise, is recently reported as the largest single volcano known on Earth. This work seeks to understand the type of volcanism necessary to form such an anomalously large single volcano by integrating core and high-resolution wireline logging data. In particular, resistivity imagery obtained by the Formation MicroScanner, in Integrated Ocean Drilling Program Hole U1347A, located on the eastern flank of Tamu Massif, was used to construct a logging-based volcanostratigraphy. This model revealed two different volcanic stages formed Tamu Massif: (i) the core part of the massif's basaltic basement was formed by a "construction phase" of volcanism with cyclic eruption events from a steady state magma supply and (ii) the very topmost basaltic section was formed by a "depositional phase" of volcanism during which long-traveling lava flows were deposited from a distant eruption center.

  14. Subcontinental rift initiation and ocean-continent transitional setting of the Dinarides and Vardar zone: Evidence from the Krivaja-Konjuh Massif, Bosnia and Herzegovina

    Faul, Ulrich H.; Garapi?, Gordana; Lugovi?, Boško

    2014-08-01

    The Dinaride and Vardar zone ophiolite belts extend from the south-eastern margins of the Alps to the Albanian and Greek ophiolites. Detailed sampling of the Krivaja-Konjuh massif, one of the largest massifs in the Dinaride belt, reveals fertile compositions and an extensive record of deformation at spinel peridotite facies conditions. High Na2O clinopyroxene and spinel-orthopyroxene symplectites after garnet indicate a relatively high pressure, subcontinental origin of the southern and western part of Krivaja, similar to orogenic massifs such as Lherz, Ronda and the Eastern Central Alpine peridotites. Clinopyroxene and spinel compositions from Konjuh show similarities with fertile abyssal peridotite. In the central parts of the massif the spinel lherzolites contain locally abundant patches of plagioclase, indicating impregnation by melt. The migrating melt was orthopyroxene undersaturated, locally converting the peridotites to massive olivine-rich troctolites. Massive gabbros and more evolved gabbro veins cross-cutting peridotites indicate continued melt production at depth. Overall we infer that the massif represents the onset of rifting and early stages of formation of a new ocean basin. In the south of Krivaja very localized chromitite occurrences indicate that much more depleted melts with supra-subduction affinity traversed the massif that have no genetic relationship with the peridotites. This indicates that volcanics with supra-subduction affinity at the margins of the Krivaja-Konjuh massif record separate processes during closure of the ocean basin. Comparison with published compositional data from other Balkan massifs shows that the range of compositions within the Krivaja-Konjuh massif is similar to the compositional range of the western massifs of the Dinarides. The compositions of the Balkan massifs show a west to east gradient, ranging from subcontinental on the western side of the Dinarides to depleted mid-ocean ridge/arc compositions in the Vardar zone in the east. This is consistent with the hypothesis that both ophiolite belts originate in a single ocean, rather than from two separate basins. A distinct decrease in fertility occurs in the south of the Dinarides towards the Albanian ophiolites with supra-subduction affinity.

    Bromeliaceae is an important botany family that includes many species with economic value; demand for members of this family is increasing. However, illegal collection frequently occurs, drastically reducing the species populations; thus, it is necessary to collect and store Bromeliaceae genetic material. In this study, we identified and quantified genetic variability of the Bromeliad family using dominant markers to create the first Germplasm Bank in the northeast region of Brazil. Molecular tools were used to characterize the collected accessions. The combination of 11 inter-simple sequence repeats and 13 random amplified polymorphic DNA markers were used to detect the genetic variability of wild bromeliad accessions. PMID:25501194

  18. Pleistocene geomorphological and sedimentary development of the Akaki River catchment (northeastern Troodos Massif) in relation to tectonic uplift versus climatic change

    Main, Charlotte E.; Robertson, Alastair H. F.; Palamakumbura, Romesh N.

    2015-10-01

    The uplift of the Troodos ophiolite is reflected in the development of the Akaki River catchment in the northeast Troodos Massif. Four main stages (F1-F4) of geomorphological terrace development and related deposits are recognised using satellite imagery and field observations. The geomorphological terraces have been tectonically uplifted during the Pleistocene so that they dip northwards from the Troodos Mountains until they merge with the Mesaoria Plain. Lithology (e.g. hard diabase versus soft extrusive rock) has exerted an important control on the geomorphology of the Akaki River channel. The F1 terraces and related deposits are well preserved in the lower reaches of the catchment. The F2 terraces are more widely preserved but with few preserved deposits. The F3 erosional surfaces (e.g. strath terraces) and related deposits are widespread up into the higher reaches of the catchment. The F4 to recent geomorphological surfaces and deposits are confined to near the modern river channel. The F1- to F3-aged deposits each include very high-energy mass-flow deposits and somewhat lower-energy traction-flow deposits, with minimal sand preservation. Stages of fluvial aggradation were followed by soil development (e.g. terra rossa). The F1- to F4-aged terraces and related deposits mainly formed in response to a combination of very long-term tectonic uplift and climatic-related change (long term and short term). Tectonic uplift was the dominant driver related to the updoming of the Troodos ophiolite, especially during the earlier time period (F1 and F2), whereas climate-related effects appear to have dominated more recently (F3 and F4). Sedimentary aggradation is likely to have predominated during interglacial periods, while interglacial-glacial transitions (when climate fluctuated) are seen as times of increased incision. Previous correlations of the F1-F4 fluvial deposits with similar deposits elsewhere in Cyprus, including coastal marine carbonate deposits, suggest that the F1 and F2 deposits are likely to be of Middle Pleistocene age and the F3-F4 deposits of Late Pleistocene to Holocene age.

  19. New insights into the history and origin of the southern Maya block, SE Mexico: U-Pb-SHRIMP zircon geochronology from metamorphic rocks of the Chiapas massif

    2007-01-01

    The histories of the pre-Mesozoic landmasses in southern México and their connections with Laurentia, Gondwana, and among themselves are crucial for the understanding of the Late Paleozoic assembly of Pangea. The Permian igneous and metamorphic rocks from the Chiapas massif as part of the southern Maya block, México, were dated by U–Pb zircon geochronology employing the SHRIMP (sensitive high resolution ion microprobe) facility at Stanford University. The Chiapas massif is composed of deformed granitoids and orthogneisses with inliers of metasedimentary rocks. SHRIMP data from an anatectic orthogneiss demonstrate that the Chiapas massif was part of a Permian (? 272 Ma) active continental margin established on the Pacific margin of Gondwana after the Ouachita orogeny. Latest Permian (252–254 Ma) medium- to high-grade metamorphism and deformation affected the entire Chiapas massif, resulting in anatexis and intrusion of syntectonic granitoids. This unique orogenic event is interpreted as the result of compression due to flat subduction and accretionary tectonics. SHRIMP data of zircon cores from a metapelite from the NE Chiapas massif yielded a single Grenvillian source for sediments. The majority of the zircon cores from a para-amphibolite from the SE part of the massif yielded either 1.0–1.2 or 1.4–1.5 Ga sources, indicating provenance from South American Sunsás and Rondonian-San Ignacio provinces.

    The Greenland Ice Sheet (GrIS) has been one of the largest contributors to global sea level rise over the last 20 years, accounting for c. 0.5 of a total of c. 3.2 mm yr-1. A significant portion of this contribution is associated with the speed up of glaciers in southeast and northwest Greenland. Here, we reveal that the Northeast Greenland Ice Stream (NEGIS), which extends more than 600 km into the interior of the ice sheet, is now undergoing dynamic thinning after more than a quarter of a century of stability. This sector of the GrIS is of particular interest in sea level projections, because the glacier flows into a large submarine basin with a negative bed slope near the grounding line. Our findings unfold the next step in mass loss of the GrIS as we show a heightened risk of rapid sustained loss from Northeast Greenland on top of the thinning in Southeast and Northwestern Greenland.

  8. Isotope-geochemical Sm-Nd, ENd and TDM data of the layered paleoproterozoic PGE massif Monchetundra (Kola peninsula)

    NASA Astrophysics Data System (ADS)

    2014-05-01

    Monchetundra massif is located in the central part of the Kola Peninsula and it is the south-eastern part of the Main Ridge Intrusion. The massif is subdivided into two up to five syngenetic zones by different researchers (Nazimova, Rayan, 2008, Nerovich et. al. 2009, Layered intrusions…p.1, 2004). According the isotope-geochronological and isotope-geochemical data it can identify at least four groups of rocks distinguishing by ages. The aim of this study is to identify the isotope-geochemical Sm-Nd (ENd and TDM) data of the mafic rocks of the massif Monchetundra. For the interpretation of these data it was selected 40 analyzes of rocks sampled during field works within Monchetundra massif in 2011-2012 and from the published data (Nerovich et. al., 2009, Bayanova et. al., 2010, Layered intrusions…p.2, 2004). The earliest group of rocks is dated by U-Pb zircon in 2521 ± 8 Ma (Bayanova et. al., 2010). It consist of metagabbroids of wide composition range from anorthosite up to gabbro, which also called «amphibole-plagioclase rocks» (Nerovich et. al., 2009) due to their strong metamorphic changes. These rocks are characterized by ENd values from -0.02 up to -2.23 (at the time of rocks formation) as well as mesoarchean and paleoarchean values of model ages. The second group of rocks is composed of medium- grained and coarse-grained mesocratic gabbronorites of trachytoid texture and their amphibolized varieties. The rocks of this group were dated in 2505 ± 6 Ma and 2501 ± 8 Ma (Layered intrusions…p.1., 2004). Values of ENd for these rocks vary from -1.70 up to +1.42, model ages correspond to the range from 2.7 up to 3.5 Ga. Leucocratic gabbronorites, gabbronorite-anorthosites of massive texture and their metamorphosed varieties with garnet and amphibole constitute the third group of Monchetundra massife rocks. The formation age of these rocks has been determined on zircon and baddeleyite by U-Pb method and it is 2471 ± 9 Ma, 2476 ± 17 Ma, 2456 ± 5 Ma and 2453 ± 4 Ma (Bayanova et. al., 2010, Mitrofanov et. al., 1993). Value of ENd for this group rocks vary from -3.38 to +2.08, and the values of the model ages range between 2.7 and 3.4 Ga. Dyke-shaped bodies of melanocratic troctolites are found within the southeastern slope of Monchetundra massif. These rocks are characterized by positive values of ENd varying from +2.01 to +3.28, and the values of model ages are close to 2.7 Ga. Gabbro-pegmatites occur at the upper part of the Monchtundra massif and are characterized by negative ENd values from -1.26 up to -0.63, and model ages of protolith range from 3.0 to 3.2 Ga. Isotope-geochemical Sm-Nd (ENd and TDM) data indicate the origining of gabbro massif from EM-1 mantle plume reservoir and this fact is confirmed by the ENd-ISr diagrams in accordance with published data (Bayanova et. al., 2009). The research is conducted with the financial support of RFBR 13-05-00493, OFI-M 13-05-12055, 14-05-93965 and 14-05-00484.

  9. Exploitation de la fracturation d'un massif par la karstification: exemple du Causse de l'Hortus (Hérault, France)

    NASA Astrophysics Data System (ADS)

    Boinet, Nathanaël

    1999-05-01

    The Causse de l'Hortus is a particularly well adapted massif to the survey of the fracturation and to its interdependences with karstification. The on-going realisation of a hydrogeological and speleological monograph of the massif, as well as the existence of more than twenty kilometers of prospected channels belonging to the active networks, provide new data which can be compared with previous surveys carried out in this field. The comparison of the directions of fracturation, visible on aerial photographs with directions currently exploited by the karstic channels on the whole Causse, show the effect of the greater fractures and the influence of the hydraulic gradient on the exploitation of the fracture spectrum. To sum up, the display of the relationships between the dextral disconnecting faults and the temporary emergences of the "boulidou" type, results in concrete applications for speleological and hydrogeological aspects. The survey of these "boulidous" provides new information about the vertical structuration of the karst.

    The MASSIF (Masses and Stellar Systems with Interferometry) Team will use SIM to investigate the mass content of the Galaxy - from huge stars to barely glimmering brown dwarfs, and from hot white dwarfs to exotic black holes. We will target various samples of the Galactic population to determine and relate the fundamental characteristics of mass, luminosity, age, composition, and multiplicity - attributes that together yield an extensive understanding of the stars. Our samples will include distant clusters that span a factor of 5000 in age, and commonplace stars and substellar objects that lurk near the Sun. The principal goals of the MASSIF Key Project are to (1) define the mass-luminosity relation for main sequence stars in five fundamental clusters so that effects of age and metallicity can be mapped (Trapezium, TW Hydrae, Pleiades, Hyades, and M67), and (2) determine accurate masses for representative examples of nearly every type of star, stellar descendant or brown dwarf in the Galaxy.

Acta Geologica Polonica, 63 (2), 223-237. Warszawa. The foraminiferal and radiolarian biostratigraphy of selected sections of the Zabijak Formation, the youngest sediments of the Tatra massif (Central Western Carpathians), have been studied. Benthic foraminifers, mainly agglutinated species, occur abundantly and continuously throughout the studied succession, while planktic foraminifers are generally sparse. Five planktic and two benthic foraminiferal zones have been recognized. The marly part of the Zabijak Formation comprises the Pseudothalmanninella ticinensis (Upper Albian) through the Rotalipora cushmani (Upper Cenomanian) planktic foraminiferal zones, and the Haplophragmoides nonioninoides and Bulbobaculites problematicus benthic foraminiferal zones. The radiolarians were recognized exclusively in the Lower Cenomanian part of the formation.

  12. The thermal, metamorphic and magmatic evolution of a rapidly exhuming terrane: the Nanga Parbat Massif, northern Pakistan

    NASA Astrophysics Data System (ADS)

    Whittington, A. G.

    The Nanga Parbat-Haramosh Massif (NPHM) is the most northerly outcrop of Indian Plate rocks in the Himalayan orogen, exposed by rapid recent exhumation through the structurally overlying Kohistan Island Arc in northern Pakistan. Exhumation has been achieved by erosion in the apparent absence of extensional tectonics. Metabasaltic dykes intruded into polymetamorphic basement rocks provide time markers that distinguish early from late fabrics that probably correlated with Precambrian and Himalayan deformation respectively. Nanga Parbat is anomalous within the Himalayan orogen for both the timing and nature of metamorphism and anatexis. A multidisciplinary approach allows the thermal history to be tightly constrained. Metamorphism is characterised by cordierite growth during near-isothermal decompression. Garnet inclusion assemblages record P-T conditions of 720 +/- 50 deg C and 7.5 +/- 1.5 kbar, while spinel-cordierite intergrowths unique to the massif interior formed at 710 +/- 60 deg C and 5.0 +/- 1.1 kbar. Lower grade assemblages are exposed towards the massif margins. Tourmaline leucogranite plutons and sheets are characterised by similar trace element geochemistry to Miocene High Himalayan granites, indicative of vapour-absent crustal melting as would result from rapid decompression, but were emplaced more than 10 million years later. More recently, fluid infiltration into conjugate shear zones accommodating vertical stretching in the core of the massif resulted in anatexis and the formation of restitic cordierite-bearing pods. 40Ar-39Ar studies indicate regional cooling below 400 deg C as recently as 1 Ma, and the distribution of excess 40Ar in basement samples is indicative of magmatic/metamorphic fluids at depths > 10 km. One-dimensional thermal modelling indicates that increasing cooling rates through time do not require increasing exhumation rates because advection of heat results in a steepened near-surface geotherm. These models predict both the style and timing of metamorphism and anatexis in this rapidly exhuming terrane, and are consistent with petrological and geochemical constraints determined from the NPHM basement.

  13. Phanerozoic polyorogenic deformation in southern Jiuling Massif, northern South China block: Constraints from structural analysis and geochronology

    NASA Astrophysics Data System (ADS)

    Chu, Yang; Lin, Wei

    2014-06-01

    The structure of the Jiuling Massif has been investigated in order to delineate the polyorogenic deformation and discuss its geodynamic evolution and orogenic mechanisms. Detailed structural analysis indicates that the D1 event is characterized by top-to-the NNW ductile shearing with pervasive foliation, and mineral and stretching lineation developed in the entire region. Compared with the D1 deformation, D2 structures are localized in ductile shear zones with subvertical foliation and subhorizontal E-W trending lineation, indicating a dextral ductile shearing. The D3 event, marked by folds and thrusts mainly in a brittle domain, modified the D1 structures by asymmetrical folds. The dominant D4 structures are gravitational folds and normal faults, corresponding to a later extension. Our new geochronological data suggest that the D1 event occurred between 465 and 380 Ma with D2 dextral shearing at the end of this Early Paleozoic orogen, and the D3 event has been constrained at 245-215 Ma. The final uplift of the Jiuling Massif by the D4 event can be correlated with the Late Mesozoic extension across the eastern South China block. Along with previous studies in the South China block, the structural pattern of the Jiuling Massif elucidates the influence of the Early Paleozoic and Early Mesozoic intracontinental belts triggered by repeated reactivation of the Jiangshan-Shaoxing Fault. Combined with deformation to the south, the Early Paleozoic belt shows a positive flower pattern, with opposing kinematics, rooted in the Jiangshan-Shaoxing Fault. During the Early Mesozoic, a general intracontinental belt was developed with uniform kinematics in both the Jiuling Massif and the Xuefengshan Belt, possibly resulted from the far-field effect of the Triassic NW-directed Paleo-Pacific subduction.

  14. Gneiss domes, metamorphic core complexes, and wrench zones: Thermal and structural evolution of the Ni?de Massif, central Anatolia

    NASA Astrophysics Data System (ADS)

    Whitney, Donna L.; Teyssier, Christian; Heizler, Matthew T.

    2007-10-01

    The Ni?de Massif, a migmatite-cored structural dome in south central Turkey, was metamorphosed, deformed, intruded, and exhumed in an oblique tectonic regime involving a switch from transpression (prograde metamorphism) to transtension (exhumation). An 80 Ma history of transpression and transtension is recorded in metamorphic rocks of the massif, and the last ˜50 Ma are recorded in both basement and overlying basin deposits. Ni?de metamorphic rocks record a high-temperature, top-to-north, syntranspression ductile fabric that was overprinted by lower-grade, top-to-south, syntranstension ductile shear zones. The 40Ar/39Ar data for hornblende, muscovite, and biotite document rapid Late Cretaceous cooling, with the oldest Ar hornblende ages (88-79 Ma) overlapping U-Pb ages in monazite and zircon (92-78 Ma). Muscovite Ar ages are dominantly 81-79 Ma, suggesting a short time between crystallization of high-temperature metamorphic rocks and their cooling. Biotite Ar ages are 79-74 Ma, with the exception of disturbed samples from the eastern margin of the massif and from Eocene granitic stocks in the dome core. The eastern margin, adjacent to the sinistral Central Anatolian Fault Zone, records another cycle of burial and exhumation that overprinted earlier fabrics and disturbed isotopic systems. These two cycles of burial-exhumation took place repeatedly along the same zone; this may be characteristic of highly oblique tectonic regimes. In the Ni?de Massif, burial and exhumation became more localized and of lower amplitude over time, suggesting stabilization of the crust.

  15. Lower Pliensbachian caldera volcanism in high-obliquity rift systems in the western North Patagonian Massif, Argentina

    NASA Astrophysics Data System (ADS)

    Benedini, Leonardo; Gregori, Daniel; Strazzere, Leonardo; Falco, Juan I.; Dristas, Jorge A.

    2014-12-01

    In the Cerro Carro Quebrado and Cerro Catri Cura area, located at the border between the Neuquén Basin and the North Patagonian Massif, the Garamilla Formation is composed of four volcanic stages: 1) andesitic lava-flows related to the beginning of the volcanic system; 2) basal massive lithic breccias that represent the caldera collapse; 3) voluminous, coarse-crystal rich massive lava-like ignimbrites related to multiple, steady eruptions that represent the principal infill of the system; and, finally 4) domes, dykes, lava flows, and lava domes of rhyolitic composition indicative of a post-collapse stage. The analysis of the regional and local structures, as well as, the architectures of the volcanic facies, indicates the existence of a highly oblique rift, with its principal extensional strain in an NNE-SSW direction (˜N10°). The analyzed rocks are mainly high-potassium dacites and rhyolites with trace and RE elements contents of an intraplate signature. The age of these rocks (189 ± 0.76 Ma) agree well with other volcanic sequences of the western North Patagonian Massif, as well as, the Neuquén Basin, indicating that Pliensbachian magmatism was widespread in both regions. The age is also coincident with phase 1 of volcanism of the eastern North Patagonia Massif (188-178 Ma) represented by ignimbrites, domes, and pyroclastic rocks of the Marifil Complex, related to intraplate magmatism.

  16. Geochronology and geochemistry of late Paleozoic volcanic rocks on the western margin of the Songnen-Zhangguangcai Range Massif, NE China: Implications for the amalgamation history of the Xing'an and Songnen-Zhangguangcai Range massifs

    NASA Astrophysics Data System (ADS)

    Li, Yu; Xu, Wen-Liang; Wang, Feng; Tang, Jie; Pei, Fu-Ping; Wang, Zi-Jin

    2014-09-01

    We here elucidate the tectonic evolution of the Xing'an and Songnen-Zhangguangcai Range massifs during the early Carboniferous-early Permian, based on zircon U-Pb dating and whole-rock geochemical analyses of volcanic rocks of the Songnen-Zhangguangcai Range Massif in the Sunwu area, Heilongjiang Province, NE China. Euhedral-subeuhedral zircons from three rhyolites and one dacite from the study area display fine-scale oscillatory growth zoning, indicating a magmatic origin. Zircon U-Pb dating by LA-ICP-MS indicates that these acidic volcanic rocks formed in the early Carboniferous-early Permian; i.e., early Carboniferous (~ 351 Ma), early late Carboniferous (~ 319 Ma), and early Permian (295-293 Ma). The early Carboniferous rhyolites exhibit chemical affinities to A-type rhyolites, implying an extensional environment. Their positive ?Hf(t) values (+ 8.67 to + 13.4 except for one spot of + 1.63) and Hf two-stage model ages (TDM2 = 562-988 Ma) indicate that the primary magma was possibly derived from partial melting of newly accreted continental crust. The early late Carboniferous rhyolites and dacites (~ 319 Ma) exhibit calc-alkaline peraluminous signature [molar Al2O3/(CaO + K2O + Na2O) ratio, or A/CNK = 1.04-1.22]. The ?Hf(t) values and TDM2 ages of zircons from the 319 Ma dacites are in the range of + 5.33 to + 9.32 and 907-1268 Ma, respectively, suggesting that the primary magma was derived from partial melting of newly accreted crust. The early Permian rhyolites (295-293 Ma) show chemical affinities to A-type rhyolites, implying an extensional tectonic environment; their positive ?Hf(t) values (+ 8.82 to + 13.8) and Hf two-stage model ages (484-743 Ma) indicate that the primary magma was derived from partial melting of newly accreted crust. Combined with the geochemical features of coeval igneous rocks from the eastern margin of the Xing'an Massif, these data reveal the late Paleozoic tectonic history and relationships of the Xing'an and Songnen-Zhangguangcai Range massifs, i.e., early Carboniferous westward subduction of the Paleo-Asian oceanic plate beneath the Xing'an Massif, followed by early late Carboniferous collision and amalgamation of microcontinental blocks, and early Permian post-collisional extension.

  17. Seismotectonic significance of the 2008-2010 Walloon Brabant seismic swarm in the Brabant Massif, Belgium

    NASA Astrophysics Data System (ADS)

    Van Noten, Koen; Lecocq, Thomas; Shah, Anjana K.; Camelbeeck, Thierry

    2015-08-01

    Between 12 July 2008 and 18 January 2010 a seismic swarm occurred close to the town of Court-Saint-Etienne, 20 km SE of Brussels (Belgium). The Belgian network and a temporary seismic network covering the epicentral area established a seismic catalogue in which magnitude varies between ML -0.7 and ML 3.2. Based on waveform cross-correlation of co-located earthquakes, the spatial distribution of the hypocentre locations was improved considerably and shows a dense cluster displaying a 200 m-wide, 1.5-km long, NW-SE oriented fault structure at a depth range between 5 and 7 km, located in the Cambrian basement rocks of the Lower Palaeozoic Anglo-Brabant Massif. Waveform comparison of the largest events of the 2008-2010 swarm with an ML 4.0 event that occurred during swarm activity between 1953 and 1957 in the same region shows similar P- and S-wave arrivals at the Belgian Uccle seismic station. The geometry depicted by the hypocentral distribution is consistent with a nearly vertical, left-lateral strike-slip fault taking place in a current local WNW-ESE oriented local maximum horizontal stress field. To determine a relevant tectonic structure, a systematic matched filtering approach of aeromagnetic data, which can approximately locate isolated anomalies associated with hypocentral depths, has been applied. Matched filtering shows that the 2008-2010 seismic swarm occurred along a limited-sized fault which is situated in slaty, low-magnetic rocks of the Mousty Formation. The fault is bordered at both ends with obliquely oriented magnetic gradients. Whereas the NW end of the fault is structurally controlled, its SE end is controlled by a magnetic gradient representing an early-orogenic detachment fault separating the low-magnetic slaty Mousty Formation from the high-magnetic Tubize Formation. The seismic swarm is therefore interpreted as a sinistral reactivation of an inherited NW-SE oriented isolated fault in a weakened crust within the Cambrian core of the Brabant Massif.

    Microdiamond inclusions in garnet delineate the Rhodope Massif (RM) as a globally important UHP locality. To date there are 4 confirmed UHP localities across the RM, with UHP indicators being restricted to garnets from metapelites. All available protolith and metamorphic ages from the RM are based on accessory minerals such as zircon and monazite, which yield a disparate array of ages spanning from pre-Variscan to post-Alpine (Eocene) times. The best estimate for the timing of the UHP event is that it was associated with a subduction event during the Jurassic1. This study focuses on garnets from UHP metapelites from the Central Rhodope Mts., Bulgaria, in the vicinity of the town of Chepelare. It is the first to date directly the host of the UHP indicators in the region, eliminating the risks of interpretations based on inherited inclusions. Aggregates of garnets have been dated via Sm/Nd geochronology, following a rigorous sample preparation and partial dissolution process to remove the effect of REE rich inclusions that result in low Sm/Nd ratios. Aggregate garnet ages range between 91.5 ± 4.6 Ma and 70.3 ± 2.3 Ma, which correlates well with the age of magmatic activity seen across the region. These Late Cretaceous ages are significantly younger than the proposed Jurassic UHP metamorphic event, but correlate well with another proposed (U)HP event, based on U-Pb zircon dating2. Current tectonic models for the RM invoke either a protracted subduction cycle with a single, long lasting (>30Ma long) exhumation event, or a series of complex subduction -exhumation cycles preserved in multiple suture zones. We will attempt to link our new garnet Sm/Nd ages with the complex post-Jurassic tectonic evolution of the RM, and in particular add constraints to the much debated questions surrounding the nature of the exhumation of the UHP units and the evolution of the massif. 1Burg, J., 2011, Journal of the Virtual Explorer, 42, paper 1 2Liati, A.,et al., 2011,.

    Hydrogeological models based on well-exposed mountain massifs permitt to constrain the geological factors affecting water circulation and water-rock interaction. Our study adresses the question of how sudden lateral rock changes (sedimentologic facies evolution) affect hydrodinamics in the case of ancient fan deltas. A robust model for the Sant Llorenç del Munt massif (Eocene, Barcelona province) has been defined after the integration of geology (stratigraphy, sedimentology, mapping and integration of subsurface data) and groundwater hydrology (pumping tests, major ions hydrochemistry and environmental isotopes). Ten lito-hidrostratigraphic units have been recognized, which correspond to different sedimentary environments and have a distinctive response to water circulation and water-rock interaction. A remarkable point of this case study is that the size of the whole sedimentary system is considered, i.e. the lateral expansion of flow (lateral permeability barriers) is fully contrained. In terms of hydrogeology, hydraulic conductivity due to fracturing provide poor aquifers in 4 rock types. 5 hydrochemical groups have been established which allow explaining the evolution of the flow throughout the fan delta. Together with isotopic and stratigraphic data the main recharge areas have been determined. Flow dynamics throughout the system combines both surface runoff and subsurface flow. In proximal alluvial conglomerates, groundwater runs both vertically (fractures) and horizontally (fractured and karstified levels). Some features that are generally overlooked in hydrogeological studies (such as conglomerate petrology) are crucial for fracturation and karstic development. Laterally, conglomerates evolve to impermeable mudstones with sandstones (alluvial fan fringe). However, some conglomerates prograding locally reach distal (marine) sediments and recharge the fractured delta front sandstones aquifers that are also refilled by runoff waters. The end sediments (prodelta marls) provide an ultimate permeability barrier of the system. In general, lithologies arrangement due to past fluctuating distribution of sediments (sedimentary architecture) are crucial in the vertical and horizontal location of the aquifers levels. Interestingly, our study based on ancient rocks can also be applied to present day systems. Original sediments with important primary porosity are later better cemented (lithified) into indurated rocks and then more fracturated. So that, it indicates that in current and ancient fan deltas, better aquifers levels develop in the same strata independently of the transmisivity origin (primary porosity or fracturation).

  20. Methane Seepage at Hyperalkaline Springs in the Ronda Peridotite Massif (Spain)

    Methane-rich, hyperalkaline spring waters and bubbling pools have been sampled in the Ronda peridotite massif in southern Spain. Water chemistry (T: 17.1-21.5 ºC; pH: 10.7-11.7; DO: <2 mg/L; Ca-OH facies) is characteristic of present-day serpentinization. Dissolved CH4 concentrations range from 0.1 to 3.2 mg/L. CH4 stable C and H isotope ratios suggest a dominant abiotic origin in two natural spring sites (delta13C: -13 to -29 ‰ VPDB; delta2H: -309 to -333 ‰ VSMOW) and a mixed biotic-abiotic origin in springs with artificial water delivery systems (i.e., pipes or fountains; delta13C: -44 to -69 ‰; delta2H: -180 to -319 ‰). At the natural springs, gas is mainly released through bubbles close to the water outlet (CH4 flux ~1 kg/day by individual bubble trains), and subordinately by microseepage from the ground, even at distances of ~100 m from the bubble-spring site (flux of 10's, up to 97, mg CH4 m-2day-1). Gas seepage is strictly controlled by faults. Under-saturation of CH4 in water, bubbling and seepage location suggest that CH4 is not exclusively transported to the surface by hyperalkaline water, but it follows autonomous migration pathways along faults. Similar 'dry' seepage of abiotic gas was observed in the Philippines, New Zealand, Turkey and Italy. Like other land-based serpentinization systems, the Ronda peridotite massif is characterized by low heat flow (<40 mW/m2), with temperatures <60°C at depths of 1.5 km. At these low T and high pH conditions, CO32- is the only available carbon source dissolved in the water, and unlikely contributes to catalysed Fischer-Tropsch Type reactions. Methane production from CO2 hydrogenation in a gas phase system (unsaturated fractured rocks) cannot be excluded. The presence of ruthenium-enriched chromitites in the Ronda peridotites may support the hypothesis that CH4 is produced by CO2 hydrogenation catalyzed by Ru minerals, even at temperatures below 100°C, as demonstrated in recent laboratory experiments (Etiope and Ionescu, 2014, Geofluids, in press).

    Monchetundra massif is located in the central part of the Kola Peninsula (Russia) and it is the south-eastern part of the Main Ridge Intrusion. Monchetundra massif together with well-known layered mafic-ultramafic PGE-bearing intrusions in the Fennoscandian shield such as the Fedorovo-Pansky complex, the mt. Generalskaya, the Monchepluton is of interest as a target for the PGE prospecting (Mitrofanov et al. 2006; Nerovich et al., 2009; Grokhovskaya et al., 2003). According to some previously researchers (Nazimova, Rayan, 2008, Nerovich et al., 2009, Layered intrusions…p.1, 2004) rocks of the Monchetundra massif is subdivided into two to five syngenetic zones. Hence the last isotope-geochronological and isotope-geochemical data revealed that the massif includes at least four groups of mafic rocks distinguished by formation ages (Bayanova et al., 2010). The aim of this work is to present Sm-Nd dating results of trachytoid gabbronorites, which are the second mafic rocks group in the Monchetundra massif. The Sm-Nd investigations for these rocks were carried out for the first time. The second group of mafic rocks comprises of medium-grained and coarse-grained mesocratic gabbronorites of trachytoid texture, with they characterized by well-preserved primary magmatic minerals and gabbro-ophitic texture. The U-Pb ages on single zircon-baddeleyite for these rocks recently obtained (2505 ± 6 Ma, 2501 ± 8 Ma, 2504.4±2.7 Ma and 2507.5±7.7 Ma (Layered intrusions…p.1., 2004, Borisenko et al., 2013)). Two samples of trachytoid gabbronorites were selected to study these rocks by Sm-Nd isotopic method. Mineral isochrons plotted from plagioclase, ortho- and clinopyroxene and whole-rock minerals gave ages of 2496±27 (MSWD = 0.9; ?Nd = -1.6±0.5) and 2492±55 Ma (MSWD = 0.5; ?Nd = -1.7±0.5). The new Sm-Nd ages obtained are close to the U-Pb data on zircons and baddeleyites for this rocks group and consider as oridin of second mafic rocks group. All investigations are devoted to memory of academician RAS, professor F. Mitrofanov (Russia), he was a leader of scientific school for geology, geochemistry and metallogeny of ore deposits. The researches are conducted with the financial support of RFBR 13-05-00493, OFI-M 13-05-12055, IGCP-SIDA 599.

    This oblique view, looking northeast from central Egypt, shows great expanses of the sand covered and rocky Western Desert in the foreground (bottom). The dark patches bottom right are the Dakhla Oases on the south side of an escarpment. The northern half of Egypt's Nile appears here, from about the latitude of Luxor to the delta. Green colors indicate the small area of crops which feed Egypt's population of 55 million. The Nile Delta is partly obscured by a band of clouds, but can be discerned at the coast as a flattened triangle of green. The smaller triangle close by is the Falyum Basin, a depression irrigated by water from the Nile. The coast of the Mediterranean Sea appears left.

    After 8 years of decay of its ice shelf, Zachariæ Isstrøm, a major glacier of northeast Greenland that holds a 0.5-meter sea-level rise equivalent, entered a phase of accelerated retreat in fall 2012. The acceleration rate of its ice velocity tripled, melting of its residual ice shelf and thinning of its grounded portion doubled, and calving is now occurring at its grounding line. Warmer air and ocean temperatures have caused the glacier to detach from a stabilizing sill and retreat rapidly along a downward-sloping, marine-based bed. Its equal-ice-volume neighbor, Nioghalvfjerdsfjorden, is also melting rapidly but retreating slowly along an upward-sloping bed. The destabilization of this marine-based sector will increase sea-level rise from the Greenland Ice Sheet for decades to come. PMID:26563135

    Although calcite tectonites are widespread in nature their use to quantify flow vorticity is limited. We use new (micro-)structural, petrofabric and vorticity data to analyse the kinematics of flow in outcrop-scale calcite mylonite zones. These zones are genetically related to a crustal-scale NE-directed ductile thrust (Basal Thrust) that emplaced the Blueschist over the Basal unit during the exhumation of the Attico-Cycladic Massif. Calcite microstructures reveal that the last stage of deformation occurred at temperatures 200-300 °C achieved by mild heating, which is possibly related with the reburial of the Basal Thrust's footwall. Vorticity analyses were based on the degree of asymmetry of calcite c-axis fabrics as well as on the assumption that the orientation of the long axes of calcite neoblasts within an oblique foliation delineates the direction of instantaneous stretching axis. Both methodological approaches provide consistent estimates with a simple shear component between 55% and 82% (Wn = 0.76-0.96). The use of the stress axis (?1) orientation recorded by twin-c-axis-pairs to quantify vorticity generally gives significantly lower simple shear component. Comparison of our vorticity estimates with previous estimates inferred from quartz fabrics and rigid porphyroclasts reveals that exhumation-related deformation in the nappe pile was steady state.

    We document the seafloor character on Atlantis Massif, an ocean core complex located at 30°N on the Mid-Atlantic Ridge, with an emphasis on the distribution of carbonate features. Seafloor imagery, near-bottom backscatter, and bathymetry were analyzed on the Central Dome and the Western Shoulder of the exposed footwall to the detachment, and on the Eastern Block, a hanging wall to the fault. We merged Argo II still images to produce photo-mosaics and evaluated these together with video imagery, acoustic reflectivity, and basic rock composition. The seafloor was classified as unconsolidated sediment, lithified carbonate crust, consolidated carbonate cap, exposed basement, or rubble, and the spatial distribution of each type was assessed. Unconsolidated sediment, exposed basement, and rubble were documented in all three regions studied. Lithified carbonate crust was also present on the Western Shoulder and eastern Central Dome. Consolidated carbonate cap was found on the Eastern Block. The formation of the carbonate rock is interpreted to reflect precipitation and/or sediment cementation via fluids derived from serpentinization. Both processes occur at the nearby Lost City Hydrothermal Field. The newly documented locations of seafloor carbonate lithification therefore mark pathways of past, possibly recent, fluid flux from subsurface water-rock reaction zones and represent an additional constituent of the carbon cycling hosted by oceanic lithosphere.

    Very little is known about the higher latitude inland biology of continental Antarctica. In this paper we describe the limnology and biology of the Dufek Massif, using a range of observational, microscopic and molecular methods. Here two dry valleys are home to some of the southernmost biota on Earth. Cyanobacteria were the dominant life forms, being found in lakes and ponds, in hypersaline brines, summer melt water, relict pond beds and in exposed terrestrial habitats. Their species diversity was the lowest yet observed in Antarctic lakes. Green algae, cercozoa and bacteria were present, but diatoms were absent except for a single valve; likely windblown. Mosses were absent and only one lichen specimen was found. The Metazoa included three microbivorous tardigrades ( Acutuncus antarcticus, Diphascon sanae and Echiniscus (cf) pseudowendti) and bdelloid rotifer species, but no arthropods or nematodes. These simple faunal and floral communities are missing most of the elements normally present at lower latitudes in the Antarctic which is probably a result of the very harsh environmental conditions in the area.

    The paper provides data on environmental contamination due to radionuclides' migration with water. As a result of investigations there was obtained data on character of contamination of soil cover, surface water and underflow from tunnels of Degelen massif. Character of radionuclides' spatial distribution in environment was also shown. Mobility ranges of radionuclides' vertical and horizontal movements have been established in soils both across and along the stream flow. There was also shown a possibility to forecast radionuclides' concentration in soil by specific activity of these radionuclides in water. Different concentrations of radionuclides in associated components of the ecosystem (surface waters - ground waters - soils) have shown disequilibrium of their condition in this system. Generalization of investigation results for tunnel water streams' with water inflows, chosen as investigation objects in this work, allows to forecast radionuclides' behavior in meadow soils and other ecosystems of water streams from tunnels of Degelen test site. Based on analysis of curves, describing radionuclides' behavior in horizontal direction, we can forecast, that at this stage (137)Cs and (239+240)Pu would not be distributed more than 1.5 km from the access to the daylight surface, (90)Sr - not more than 2 km.

    The Austrian portion of the Bohemian Massif is a Precambrian terrane composed mostly of highly metamorphosed rocks intruded by a series of granitoids that are petrographically similar. Rocks are exposed poorly and the subtle variations in rock type are difficult to map in the field. A detailed geochemical survey of stream sediments in this region has been conducted and included as part of the Geochemischer Atlas der Republik O??sterreich, and the variations in stream sediment composition may help refine the geological interpretation. In an earlier study, multivariate analysis of variance (MANOVA) was applied to the stream-sediment data in order to minimize unwanted sampling variation and emphasize relationships between stream sediments and rock types in sample catchment areas. The estimated coefficients were used successfully to correct for the sampling effects throughout most of the region, but also introduced an overcorrection in some areas that seems to result from consistent but subtle differences in composition of specific rock types. By expanding the model to include an additional factor reflecting the presence of a major tectonic unit, the Rohrbach block, the overcorrection is removed. This iterative process simultaneously refines both the geochemical map by removing extraneous variation and the geological map by suggesting a more detailed classification of rock types. ?? 1995 International Association for Mathematical Geology.

    In November-December 2004 a controlled source electromagnetic (CSEM) survey was carried out on the axis of the Mid-Atlantic Ridge during cruise Charles Darwin 167. The work is centred on a non-transform offset between the FAMOUS and AMAR segments, at 36 34' North. Here, a prominent feature is the Saldanha massif: a dome of unroofed mantle rocks, consisting largely of serpentised peridotites, and at whose summit significant low-temperature hydrothermal venting has been documented. Our objective is to determine the distribution of electrical resistivity and hence porosity over a volume of ~ 10 km x 10 km x 3 km vertically, in order to constrain the degree of penetration of seawater into the crust and uppermost mantle; to contrast the porosity structure here with volcanically hosted systems away from segment boundaries elsewhere on the MAR; and to constrain models of non-volcanic heat sources and hydrothermal circulation in ultramafic settings at slow spreading ridges. In addition to the CSEM survey we obtained swath bathymetry, gravity and magnetic data; water column physical properties and seafloor current data; and a number of dredge and gravity core samples. We shall present details of the data and samples, together with our preliminary analysis of the results.

    In recent decades, saline fluids have been sampled worldwide at great depths in continental basements. Although some of them have been attributed to marine transgressions, the mechanisms allowing their circulation are not understood. In this paper, we describe the horizontal and vertical distributions of moderately saline fluids (60 to 1400 mg L-1) sampled at depths ranging from 41 to 200 m in crystalline rock aquifers on the regional scale of the Armorican Massif (northwestern France). The horizontal and vertical distributions of high chloride concentrations are in good agreement with both the altitudinal and vertical limits and the succession of the three major transgressions between the Mio-Pliocene and Pleistocene ages. The mean chloride concentration for each transgression area is exponentially related to the time spanned until the present. It defines the potential laws of leaching (displacement) of marine waters by fresh meteoric waters. The results of the Armorican aquifers provide the first observed constraints for the timescales of seawater circulation in the continental crystalline basement and the subsequent leaching by fresh meteoric waters. The general trend of increasing chloride concentration with depth and the time frame for the flushing process provide useful information to develop conceptual models of the paleo-functioning of Armorican aquifers.

    Integrated Ocean Drilling Program (IODP) Expedition 340T returned to the 1.4-km-deep Hole U1309D at Atlantis Massif to carry out borehole logging including vertical seismic profiling (VSP). Seismic, resistivity, and temperature logs were obtained throughout the geologic section in the footwall of this oceanic core complex. Reliable downhole temperature measurements throughout and the first seismic coverage of the 800-1400 meters below seafloor (mbsf) portion of the section were obtained. Distinct changes in velocity, resistivity, and magnetic susceptibility characterize the boundaries of altered, olivine-rich troctolite intervals within the otherwise dominantly gabbroic se-quence. Some narrow fault zones also are associated with downhole resistivity or velocity excursions. Small deviations in temperature were measured in borehole fluid adjacent to known faults at 750 mbsf and 1100 mbsf. This suggests that flow of seawater remains active along these zones of faulting and rock alteration. Vertical seismic profile station coverage at zero offset now extends the full length of the hole, including the uppermost 150 mbsf, where detachment processes are expected to have left their strongest imprint. Analysis of wallrock properties, together with alteration and structural characteristics of the cores from Site U1309, highlights the likely interplay between lithology, structure, lithospheric hydration, and core complex evolution. doi:10.2204/iodp.sd.15.04.2013

    We report for the first time the discovery of diamond inclusions (5-30 ?m in size), identified by Raman spectroscopy and the characteristic sharp band at 1332 cm- 1 for crystalline diamond, in a garnet megacryst (? 5 cm) from the Edough Massif (NE Algeria). The garnet is adjacent to actinolite and ultramafic boudins and slices of marbles that are inserted within a major mylonite-ultramylonite band. This tectonic contact sharply delineates the Kef Lakhal oceanic unit from the granite-gneiss core below. The host garnet is almandine-dominant and is rich in exsolution of acicular rutile needles. Major and trace elements show a gradual but significant zonation from core to rim, and a sharp increase in grossular component in the rim. Trace element analyses of prismatic rutile inclusions up to 300 ?m in size indicate that the host metamorphic rock was a mafic protolith of MORB affinity. The Zr-in-rutile thermometry indicates a temperature range of 724-778 °C that we relate to rutile growth, either during prograde metamorphism or under peak UHP metamorphic conditions of ? 3.6 GPa that were reached during subduction of the UHP-rock precursors. We suggest that the mafic protolith originates from the subducted retreating Calabrian branch of the Tethyan slab, that broke or tore, and which fragments were dragged upward and thrust onto the North African margin along with the Kef Lakhal unit, shortly followed by formation of the Edough dome and opening of the Algerian basin.

    Confocal Raman imaging of fluid inclusions in garnet porphyroblasts from diamond-grade metamorphic calc-silicate rocks from the Kumdy-Kol microdiamond deposit (Kokchetav Massif, Northern Kazakhstan) reveals that these fluid inclusions consist of almost pure water with different step-daughter phases (e.g., calcite, mica and rare quartz). These fluid inclusions are characterized by negative crystal shape of the host-garnet and they exclusively occur within the core of garnet porphyroblasts. These observations are consistent with their primary origin, most likely at ultrahigh-pressure (UHP) metamorphic conditions. The euhedral newly formed garnet, different in color and composition, was found to be associated with these fluid inclusions. It is proposed that newly formed garnet and water fluid inclusions appear by reaction between the hydrous fluid and the garnet-host. These fluid inclusions provide an unequivocal record of almost pure H(2)O fluids, indicating water-saturated conditions within subducted continental crust during prograde stage and/or ultrahigh-P metamorphism.

    2010-05-01

    Use of stress inversion methods on faults measured at 33 sites located at the northwestern part of the South Portuguese Zone (Variscan Iberian Massif), and analysis of the basic dyke attitude at this same region, has revealed a prominent perturbation of the stress trajectories around some large, crustal-scale faults, like the El Castillo de las Guardas fault. The results are compared with the predictions of theoretical models of palaeostress deviations near master faults. According to this comparison, the El Castillo de las Guardas fault, an old structure that probably reversed several times its slip sense, can be considered as a sinistral strike-slip fault during the Moscovian. These results also point out the main shortcomings that still hinder a rigorous quantitative use of the theoretical models of stress perturbations around major faults: the spatial variation in the parameters governing the brittle behaviour of the continental crust, and the possibility of oblique slip along outcrop-scale faults in regions subjected to general, non-plane strain.

    Through analysis by instrumental neutron activation (INAA) of 789 individual lithic fragments from the 2 mm-4 mm grain-size fractions of five Apollo 17 soil samples (72443, 72503, 73243, 76283, and 76503) and petrographic examination of a subset, we have determined the diversity and proportions of rock types recorded within soils from the highland massifs. The distribution of rock types at the site, as recorded by lithic fragments in the soils, is an alternative to the distribution inferred from the limited number of large rock samples. The compositions and proportions of 2 mm-4 mm fragments provide a bridge between compositions of less than 1 mm fines and types and proportions of rocks observed in large collected breccias and their clasts. The 2 mm-4 mm fraction of soil from South Massif, represented by an unbiased set of lithic fragments from station-2 samples 72443 and 72503, consists of 71% noritic impact-melt breccia, 7% Incompatible-Trace-Element-(ITE)-poor highland rock types (mainly granulitic breccias), 19% agglutinates and regolith breccias, 1% high-Ti mare basalt, and 2% others (very-low-Ti (VLT) basalt, monzogabbro breccia, and metal). In contrast, the 2 mm - 4 mm fraction of a soil from the North Massif, represented by an unbiased set of lithic fragments from station-6 sample 76503, has a greater proportion of ITE-poor highland rock types and mare-basalt fragments: it consists of 29% ITE-poor highland rock types (mainly granulitic breccias and troctolitic anorthosite), 25% impact-melt breccia, 13% high-Ti mare basalt, 31 % agglutinates and regolith breccias, 1% orange glass and related breccia, and 1% others. Based on a comparison of mass- weighted mean compositions of the lithic fragments with compositions of soil fines from all Apollo 17 highland stations, differences between the station-2 and station-6 samples are representative of differences between available samples from the two massifs. From the distribution of different rock types and their compositions, we conclude the following: (1) North-Massif and South-Massif soil samples differ significantly in types and proportions of ITE-poor highland components and ITE-rich impact-melt-breccia components. These differences reflect crudely layered massifs and known local geology. The greater percentage of impact-melt breccia in the South- Massif light-mantle soil stems from derivation of the light mantle from the top of the massif, which apparently is richer in noritic impact-melt breccia than are lower parts of the massifs. (2) At station 2, the 2 mm-4 mm grain-size fraction is enriched in impact-melt breccias compared to the less than 1 mm fraction, suggesting that the <1 mm fraction within the light mantle has a greater proportion of lithologies such as granulitic breccias which are more prevalent lower in the massifs and which we infer to be older (pre-basin) highland components. (3) Soil from station 6, North Massif, contains magnesian troctolitic anorthosite, which is a component that is rare in station-2 South-Massif,contains magnesian troctolitic in impact-melt breccia interpreted by most investigators to be ejecta from the Serenitatis basin.

  18. Understanding the Tectonic Deformation of Turkish Blocks since Mesozoic; A Paleomagnetic study on the Nigde-Kirsehir Massif and the Taurides

    It is reported that the Nigde-Kirsehir massif which constitutes the main fragment of Anatolia is rifted from the Taurides-Anatolides in Mesozoic and that the Intra-Tauride ocean exist between these blocks. Another group of researchers believed that the Intra Tauride ocean did not exist. They assumed that the Nigde-Kirsehir massif existed as a promotory of the Taurides. In this sense, both the Nigde-Kirsehir massif and the Taurides experienced several deformation phases due to the consumption of the oceanic strand (s) and the amalgamation of the Anatolian blocks after collision in the end of the paleotectonic time, whereas in the neotectonic time the traces of the westwards excursion of Anatolia was effective. Previous paleomagnetic studies showed that the Nigde-Kirsehir massif rotated 90° anticlockwise during Jurassic to Eocene time and other studies showed that the collision between the Nigde-Kirsehir massif and the Pontides resulted by deformation which was accomodated by regional faults. In the south of the Nigde-Kirsehir massif, it was proposed that all the rocks in Carboniferous to Eosen were remagnetized due to nap emplacement in Eocene. Because of several alternative interpretations about the tectonic deformation of the Nigde-Kirsehir massif in relation between the Taurides and the Pontides, we report new paleomagnetic results from Late Jurassic to Miocene rocks in the Nigde-Kirsehir massif and its surrounding. A total of 138 different sites were sampled from Jurassic to Miocene rocks in the south of the Nigde-Kirsehir massif around Ki ri kkale, Tuzgölü, Uluki ?la and Kayseri, whereas in the Central Taurides Late Jurassic- Lower Cretaceous platform type carbonates and ophiolitic rocks from Mersin and Pozanti were collected. Paleomagnetic results evaluated together with previous paleomagnetic data indicate that all the studied rocks carry a magnetization before folding according to positive incremental fold tests. It has been shown that in the SE/E (SE Taurides) and the SW/W (Central Taurides) area two different sense of rotation occured. In the SE/E area, counterclockwise rotation of 18° took place in the period between Lower Cretaceous-Middle Eocene. The rotations are consistent with the thrust directions, indicating evidence for the consumption of the Intra Tauride ocean in Late Cretaceous. This result was supported by the paleolatitudes obtained for the Taurides and the Ni?de Ki r?ehir massif which showed a spatial gap of 1000 km between the Pontides and the Taurides in Late Jurassic- Lower Cretaceous and Late Cretaceous. In the SW/W, however, clockwise rotation of 47° between Middle Eocene and Miocene time, imply that the deformation occured in a later phase as a result of consumption of the South Neotethys ocean and the collision between the African and Eurasian plates. Accordingly to the paleomagnetic rotations which took place gradually in the SE/E area in Middle Eocene, it is shown that counterclockwise rotations of 25° took place in the Ni?de Ki r?ehir massif during Paleocene. This implies that the Nigde-Kirsehir massif underwent similar deformation together with the adjacent block in the SE/E. In the Neotectonic period, counterclockwise rotation of 17° was obtained in the SE/E area. It is shown that the westwards movement of Anatolia affected mainly the SE/E ares despite the SW/W and the Nigde-Kirsehir massif, which show no significant rotations. This study was financially supported by the project of the Scientific and Technical Research Council of Turkey (TUBITAK) with Project number 111Y043.
