    Syncollisional sedimentary rocks in the Himalayan orogen record important information about the early history of the India-Asia collision. This article presents a combined stratigraphic, sedimentologic, micropaleontologic, and provenance data for the Early Eocene clastic strata (Dajin Formation) in the Kailas area, southwestern Tibet. The Dajin Formation comprises ungraded and normally graded, matrix- and clast-supported conglomerates, ungraded and cross-stratified sandstones, and massive to poorly laminated mudstones. Deposition of the rocks is characterized by subaerial and subaqueous debris flows, waning gravity flows and suspension fallout. The larger benthic foraminifera and the youngest ages of the detrital zircons constrain the depositional age to the earliest Eocene (56-54 Ma). The Dajin Formation contains abundant sandstone and mudstone clasts, indicating significant sedimentary recycling in the source area. U-Pb ages of detrital zircons are mostly clustered at ~ 120-54 Ma and have positive εHf(t) values, suggesting a Gangdese affinity. Clasts of the Dajin Formation are interpreted as having recycled from the forearc strata that were originally derived from the Gangdese magmatic arc. Highly immature texture and recycled provenance lead us to propose that deposition of the Dajin Formation was a result of the development of fold-thrusts in the Gangdese forearc. Our new results and published data from the coeval strata in the Himalayan orogen indicate that an underfilled foreland basin was initiated soon after the initial India-Asia collision, and the Dajin Formation records the wedge-top depozone of the basin system.

    The India-Asia collision zone in southern Tibet preserves a record of geodynamic and erosional processes following intercontinental collision. Apatite fission-track and zircon and apatite (U-Th)/He data from the Oligocene–Miocene Kailas Formation, within the India-Asia collision zone, show a synchronous cooling signal at 17 ± 1 Ma, which is younger than the ca. 26–21 Ma depositional age of the Kailas Formation, constrained by U-Pb and 40Ar/39Ar geochronology, and requires heating (burial) after ca. 21 Ma and subsequent rapid exhumation. Data from the Gangdese batholith underlying the Kailas Formation also indicate Miocene exhumation. The thermal history of the Kailas Formation is consistent with rapid subsidence during a short-lived phase of early Miocene extension followed by uplift and exhumation driven by rollback and northward underthrusting of the Indian plate, respectively. Significant removal of material from the India-Asia collision zone was likely facilitated by efficient incision of the paleo–Indus River and paleo–Yarlung River in response to drainage reorganization and/or intensification of the Asian monsoon.

    Although it is generally assumed that the thoughts of Ernst Mach and the scientific fields he influenced (in this case psychophysics and Gestalt psychology) emigrated from Europe during Second World War they apparently survived in Finland, influencing the Finnish education system. The following article evaluates this relationship and its implications from a historical and an empirical perspective. In empirical studies comparing the education systems of different countries, such as PISA, the Finns are in general regarded as being very successful with their school system. Does this apparent success have anything to do with a Machian influence? Our current research has so far revealed that the Finns have gone through an independent cultural development in two specific aspects: in the idea of the development of the individual personality (Snellman) and in a specific phenomenalism (developed primarily by Eino Kaila, in which Kaila was heavily influenced in this by Ernst Mach). The result can be regarded as a nation-wide “Experiment”, the empirical evaluation of which can be found partly in the statistics of the PISA Studies, especially the evaluation of Finland in relation to other countries.

    Geologic mapping and geochronological analysis in southwest (Kailas area) and southeast (Zedong area) Tibet reveal two major episodes of Tertiary crustal shortening along the classic Indus-Tsangpo suture in the Yalu River valley. The older event occurred between ca. 30 and 24 Ma during movement along the north-dipping Gangdese thrust. The development of this thrust caused extensive denudation of the Gangdese batholith in its hanging wall and underthrusting of the Xigase forearc strata in its footwall. Examination of timing of major tectonic events in central Asia suggests that the initiation of the Gangdese thrust was approximately coeval with the late Oligocene initiation and development of north-south shortening in the eastern Kunlun Shan of northern Tibet, the Nan Shan at the northeastern end of the Altyn Tagh fault, the western Kunlun Shan at the southwestern end of the Altyn Tagh fault, and finally the Tian Shan (north of the tarim basin). Such regionally synchronous initiation of crustal shortening in and around the plateau may have been related to changes in convergence rate and direction between the Eurasian plate and the Indian and Pacific plates. The younger thrusting event along the Yalu River valley occurred between 19 and 10 Ma along the south-dipping Great Counter thrust system, equivalent to the locally named Renbu-Zedong thrust in southeastern Tibet, the Backthrust system in south-central Tibet, and the South Kailas thrust in southwest Tibet. The coeval development of the Great Counter thrust and the North Himalayan granite-gneiss dome belt is consistent with their development being related to thermal weakening of the north Himalayan and south Tibetan crust, due perhaps to thermal relaxation of an already thickened crust created by the early phase of collision between India and Asia or frictional heating along major thrusts, such as the Main Central thrust, beneath the Himalaya.

    The Yalu suture zone between India and Asia comprises today a central depression occupied by the Yulu River, flanked to the north and to the south by high-elevation ranges. Rivers along the suture zone are derived from such ranges and drain into the Yulu River, which in turns drains eastward. Modern sands from these rivers provide an opportunity to broadly sample rocks present within the suture zone and study their regional geochemical fingerprints and tectono-erosional implications. Seven sand samples from rivers along the suture zone in Tibet between Xigatze to the east and Mt. Kailas to the west were collected for detrital zircon U-Pb geochronological analyses, white mica 40Ar/39Ar and apatite fission track thermochronology. Zircon U-Pb ages for all rivers range between 15 and 3568 Ma. Rivers draining the northern side of the suture zone mainly yield ages between 40 and 60 Ma, similar to the age of the Gangdese arc. Samples draining the southern side of the suture zone record a Tethyan signal characterized by age clusters at 500 Ma and 1050 Ma. Samples collected from the western rivers yield zircon ages that are younger compared to those from the east; with ages predominantly <100 Ma. U-Pb zircon ages indicate that ~85% of the zircon are younger than 100 Ma in the farthest west side of the river samples (near Mt. Kailas) whereas only ~5% of zircons are younger than 100 Ma in the farthest east side of the river samples (near Xigatze). A more detailed analysis of the youngest zircon U-Pb age components reveal strong signals between 30 Ma and 100 Ma with significant peaks at 47 - 50 Ma and at 37 - 40 Ma, 57 - 63 Ma and 94 - 97 Ma, recording the activity of the magmatic arc along strike. Further analysis of the young age components (below 100 Ma) suggest a trend in age along the suture zone, with younging direction towards the west - and probably younging northward. However, the variation in ages is small. Our U-Pb detrital zircon ages are overall in agreement with

    The highest elevation of the Tibetan Plateau, lying 5,700 m above sea level, occurs within the part of the Lhasa block immediately north of the India-Tibet suture zone (Yarlung Zangbo suture zone, YZSZ), being 700 m higher than the maximum elevation of more northern parts of the plateau. Various mechanisms have been proposed to explain this differentially higher topography and the rock uplift that led to it, invoking crustal compression or extension. Here we present the results of structural investigations along the length of the high elevation belt and suture zone, which rather indicate flexural bending of the southern margin of the Lhasa block (Gangdese magmatic belt) and occurrence of an adjacent foreland basin (Kailas Basin), both elements resulting from supra-crustal loading of the Lhasa block by the Zangbo Complex (Indian plate rocks) via the Great Counter Thrust. Hence we interpret the differential elevation of the southern margin of the plateau as due originally to uplift of a forebulge in a retro foreland setting modified by subsequent processes. Identification of this flexural deformation has implications for early evolution of the India-Tibet continental collision zone, implying an initial (Late Oligocene) symmetrical architecture that subsequently transitioned into the present asymmetrical wedge architecture.

    Leech [Leech, M.L., 2008, Does the Karakoram fault interrupt mid-crustal channel flow in the western Himalaya? Earth Planet. Sci. Lett., 276, 314-322.] proposed that (1) Himalayan granites are significantly more abundant east of the Karakoram fault termination (around Mount Kailas, in SW Tibet) than west of it in the Zanskar-Kumaon region, that (2) the fault may have created a barrier to southward flow of mid-crustal channel flow, and that (3) the fault acted as a vertical conduit for these melts. These inferences are based upon new U-Pb SHRIMP data from the Leo Pargil dome, NW India, and the analysis of published U-Pb ages from additional Himalayan domes. Here we point out the flaws in all these hypotheses and suggest a much closer comparison of granites along the Karakoram shear zone to the widespread Miocene crustal melt granites of the Baltoro Karakoram range in North Pakistan. Field relationships combined with U-(Th)-Pb dating of granites and metamorphic rocks clearly shows that the leucogranites exhumed along the Karakoram fault are related to regional metamorphic and melting events along the Baltoro Karakoram range of the Asian plate and not to Indian plate Himalayan leucogranites at all. We discuss individually the points raised.

    Better constraining the geological evolution of the India-Asia suture zone is vital to our comprehension of the Himalayan-Tibetan orogen. This study presents new mapping, igneous U-Pb geochronology, and detrital zircon geochronology from suture zone rocks exposed in the Lopu Kangri Range. Located ~50 km NW of Saga in south-central Tibet, this range exposes a >1.5 km thick panel of suture zone architecture that was exhumed by late Cenozoic orogen-parallel extension across two N-S, moderate-angle normal faults. The Lopu Kangri Range and its surroundings expose all of the major suture-zone assemblages. In the north, Cretaceous--Eocene Gangdese arc granitoids are unconformably overlain by nonmarine, conglomerate-bearing strata of the Eocene (?)--Miocene Kailas Fm. Metaconglomerate exposed in the same structural position within the Range contains garnet porphyroblasts. Gangdese arc and metaconglomerate rocks are confined to the footwall of the north-directed Great Counter Thrust system, which carried Cretaceous-Early Eocene Xigaze forearc, suture zone mélange, and Indian passive margin (Tethyan) strata northwards across three major NE-SW fault strands during the Miocene. Tethyan strata in the Range consist of locally garnet- and sillimanite-bearing calc-gneiss and schist that display N-S stretching lineations and top-N s-c fabrics. These rocks are exposed in the southern half of the range beneath suture zone mélange in the footwall of a moderately N-dipping, normal-sense shear zone. Six detrital zircon samples from the Xigaze forearc, metaconglomerate and meta-Tethyan strata were analyzed to confirm our lithologic correlations and provenance interpretations made in the field. 12 igneous U-Pb samples were analyzed to characterize granitoids that intrude the Range. They reveal a suite of 50-40 Ma granitoids that display a general younging trend from north to south across the suture. Five samples of 35-10 Ma leucogranites contain inherited zircon cores whose age spectra

    Constraining the Karakorum fault (KF) slip-rate is essential to understand the present-day kinematic role of large strike-slip faults in the deformation of Tibet. The range of geodetic and geologic slip-rates is ~0 - 11 mm/yr. Cumulative offsets of alluvial fans and terrace risers ranging from 38 to 220 m add new quantitative information on its late Quaternary slip-rate. Their ages were determined using 10Be surface-exposure dating of 74 samples collected at 3 alluvial sites along the Bangong - Chaxikang and Gar basin segments, southeast of Bangong Lake. The slip-rate during the 0 - 60 ka period is 2.9(+1.0/-0.6) mm/yr at GUN, >5.3(+4.3/-1.7) mm/yr at CK and >5.3(+3.1/-2.3) mm/yr at GF. These rates are in agreement with those determined to the southeast (>5.5±0.5 mm/yr at Manikala on one strand for the same period, Chevalier et al., 2005a,b; 7.1(+3.2/-1.7) mm/yr at Menshi and 7.9(+3.2/-2.5) mm/yr near Kailas across two strands, Chevalier et al., 2012) and to the northwest (4±1 mm/yr at Tangste, Brown et al., 2002; >5 mm/yr at Muji, Chevalier et al., 2011b, both on one strand, during the Holocene). We suggest that the minimum late Quaternary slip-rate along the entire length of the KF may be relatively constant along-strike at >5 mm/yr on one fault branch or >7 mm/yr across two branches. In addition to being spatially constant, this late Quaternary rate appears to be, within error, in agreement with most studies at various timescales and suggests that at first approximation, no major discrepancy exists between geodetic and geologic rates.

    25-23 Ma cooling event bears no relationship to the activity of the KFZ, but resulted from a local metamorphic event caused either by a regional tectonic event (such as activity of the south Kailas thrust fault) or by magmatism around Shiquanhe (also known as Gar). The study of the KFZ around Namru supports the opinion that the KFZ propagated along the fault strike to the Gar-Menshi area around 12 Ma.

    from tens of meters to kilometers have been mapped using satellite imagery and field mapping, and samples ages determined by cosmic-ray exposure dating. Near Bulong Kol (39{sup o}N, 75{sup o}E) cosmogenic dating of a 40 m fluvial offset yields a slip rate of {approx}6.5 mm/yr. Near Mt. Kailas (31.5{sup o}N, 80.7{sup o}E), a glacial moraine offset by {approx}350 m has been dated at 32.3 {+-} 9.5 thousand years, yielding a slip rate of 10.8 {+-} 3.6 mm/yr. In the Gar Valley (32{sup o}N, 80{sup o}E) a river channel incised in glacial sediments yields an offset of 1750 m and an age of 283,000 years equivalent to a slip-rate of 6 mm/yr. Relative to the ATF, the slip rates on the KKF are lower than expected, and since these measurements cover almost the entire length of the KKF, the disparity cannot be attributed to along strike variation in the rate. Based upon the analysis of satellite images along the Karakorum Fault, we believe that this apparent slip deficit may be to the en echelon arrangement of multiple strike slip fault segments that characterize what should more appropriately be called the Karakorum Fault Zone. The geometric arrangement of parallel fault segments produces the ''pull apart'' basins that form the valleys along the KKF. Hence, at any given latitude, slip along the KKF may be distributed among numerous fault segments. This investigation supports efforts to understand the structure and mechanical response of the Earth's crust and supports the application of remote sensing methods.

    The NW-SE striking, dextral Karakoram fault system (KFS) stretches for more than 1200 km from the Pamirs of Central Asia at least as far southeast as the Kailas area of Tibet. It is one of the major tectonic features in the Himalayan orogen, yet considerable controversy remains about the time-integrated slip rate of the system. Geodetic data suggest present-day motion along the entire KFS occurs at 1-3 mm/yr (Wright et al., 2004, Science 305; Jade et al., 2010, GSA 116), but estimates for the integrated late Quaternary slip along various segments of the system - based on the reconstruction of dated, offset geomorphic and geologic features - range from ca. 4 mm/yr to ca. 32 mm/yr (Liu et al., 1991 in Avouac and Tapponier, 1993, GRL 20; Brown et al., 2002, JGR 107; Chevalier et al., 2005, Science 307). In the Ladakh region of NW India (34°45.27'N, 77°33.57'E), the KFS expresses as northern ('Pangong') and southern ('Tangtse') strands bounding the Pangong Range. The lack of documented Quaternary offset along the southern fault strand has led most researchers to assume that Quaternary slip on the KFS in this region was partitioned exclusively to the northern fault strand (Searle, 1998, Geological Society [London] Special Publication 135; Phillips et al., 2004, EPSL 226; Rutter et al., 2007, Journal of Structural Geology 29). However, our more recent field work in the northwestern Pangong Range has documented significant Quaternary activity along the Tangtse fault strand. Along this strand in the Tangyar Valley (34°14.26'N, 77°55.05'E), an incised debris cone has erosional risers offset ~160 m right laterally and ~25 m vertically (east side up) which is consistent with the dextral-oblique transpressional sense of motion for the KFS in this region. 10Be concentration depth profiles yield a preliminary minimum exposure age of ~30,000 yrs for the offset debris fan surfaces, which provides a maximum slip rate of ~5 mm/yr. Adjacent to the debris cone is a lower and

    Pakistan (minimum offset of 250km). Assuming that this offset accrued in time span of about 23Ma suggests average long-term rates of at least 1 cm/yr. Evidence for strike-slip faulting is also clear within the Ladakh-Karakorum range and along its SW border where mapping shows large-scale boudinage of ophiolite units implying a maximum offset of 400km along a southern branch of KFZ. South of Baer, several active strike-slip branches bound the Kailas-Ponri range to the south and continue eastwards at least up to 82.5E (lake Kunggyu). The southern part of the range is made of steep, fault-bounded slivers with clear field for brittle dextral shear. Our structural study of the area does not support inference that the Karakorum Fault terminates west of Manasarovar lake and merges with the Gurla Mandatha detachment. Instead, both deformation and large-scale geometry concur to show that the Karakorum Fault Zone continues east of 81E as a dextral, transpressive flower structure reactivating the Indus-Tsangpo suture.

    clearly indicates that industry has advanced quite significantly. During the symposium, the Indian Vacuum Society honoured two distinguished personalities for their remarkable and significant contributions to the field of vacuum science and development of technology in the country. Awards were presented for both oral and poster papers during the symposium. A committee evaluated the scientific content and clarity of presentation of contributed papers. We believe that deliberations and discussions at the symposium will help gain a better understanding of the complicated and involved technology of vacuum science and be of benefit to scientists and technologists.

    of ca. 1o x 1o. The REVEALS estimates of the past cover of PFTs will be 1) compared with the outputs of the LPJ-GUESS (10 PFTs), a widely-used dynamic vegetation model and 2) used as an alternative to the LPJ-GUESS-simulated vegetation (3 PFTs) to run for the past the regional climate model RCA3 developed at the Rossby Centre, Norrköping, Sweden. The study will evaluate and further refine these models (RCA3 and LPJ-GUESS) using a data-model comparison approach that incorporates new syntheses of palaeoclimatic data as well. It will lead to new assessments of the possible effect of various factors on climate, such as deforestations and afforestations, and changes in vegetation composition and spatial patterns of land cover/land use. Refined climate models and empirical land-cover reconstructions will shed new light on controversial hypotheses of past climate change and human impacts, such as the "Ruddiman hypothesis". First maps of REVEALS estimates of plant functional types (PFTs) are now available for Sweden, Norway, Finland, Denmark, Estonia, Poland, Germany, The Czech Republic, Switzerland and Britain (see Mazier et al. C1.21 and Trondman et al. C1.22). Correlation tests show that the REVEALS estimates are robust in terms of ranking of the PFTs' abundance (see Mazier et al, C1.21). The LANDCLIM project and network are a contribution to the IGBP-PAGES-Focus 4 PHAROS programme on human impact on environmental changes in the past. The following LANDCLIM members are acknowledged for providing pollen records, for help with pollen databases, and for providing results to the project: Mihkel Kangur and Tiiu Koff (Univ. Tallinn, Tallinn); Erik Kjellström (SMHI, Norrköping), Anna Broström, Lena Barnekow and Thomas Persson (GeoBiosphere Science Centre, Lund University); Anneli Poska (Physical Geography and Ecosystems Analysis, Lund University); Thomas Giesecke (Albrecht-von-Haller-Institute for Plant Sciences, University of Göttingen), Anne Bjune and John Birks (Dept. of
