    ABSTRACT: We present new zircon fission-track (ZFT) data from Variscan granitoid bodies in the Veporic (footwall unit) and Gemeric (hangingwall unit) thick-skinned nappe sheets of the Central Western Carpathians. All samples show Late Cretaceous to earliest Paleogene cooling ZFT ages, which contribute to constraining the low-temperature exhumation history of the Vepor-Gemer Belt. Four granite samples from the western part of the Gemericum near the contact with the underlying Veporicum provided central ZFT ages between 70.4 ± 5.4 and 74.7 ± 5.6 Ma. One sample from this area shows an older age of 87.7 ± 5.9 Ma, possibly owing to its higher structural position. One remoter sample from the SE part of the Gemeric Unit has 61.7 ± 3.4 Ma central ZFT age, which probably reflects exhumation associated with a younger compressional tectonic event in that area. One sample from the centre of the Veporic metamorphic core complex yielded a cooling age 64.9 ± 4.8 Ma. However, most of these samples exhibit an internal age scatter pointing to complex cooling and exhumation history influenced by a slow passage through the zircon partial annealing zone and/or reheating brought about by the Cretaceous Rochovce granite intrusion. In spite of this, the acquired ages generally match the exhumation trend of the Veporic metamorphic core complex.

    ABSTRACT: Alpine low-grade metamorphism related to Cretaceous orogeny has been investigated in the metasediments of the Permo-Mesozoic cover in the Veporic unit, Western Carpathians. Scythian metaquartzites, slates, schists and Middle to Late Triassic metacarbonate sediments were studied by means of optical, XRD and electrone microprobe methods. Metaclastic rocks contain mainly white mica and quartz. K-feldspar and albite are present in various amounts and chlorite can be found only sporadically in few samples. Tourmaline is the main accessory mineral. Metacarbonates are composed of recrystallized calcite and additionally dolomite, albite, K-feldspar, quartz, white mica and chlorite are present. Metaclastic rocks and metacarbonates show metamorphic grade of upper anchizonal to epizonal (greenschist facies) conditions according to the illite crystallinity (IC) measurements. IC increases with increasing celadonite content of white K-mica in studied samples. Chlorite thermometry yields a temperature of 310-330 °C in the northern part and 335-380 °C in the central and eastern part of the Veporic unit. Although the chlorite thermometry is mostly inaccurate in sedimentary rocks, since it was calibrated for volcanic rocks, the increasing trend of metamorphic temperatures in the studied units is obvious and corresponds with the obtained phyllosilicate crystallinity data. A pressure of 4-4.5 kbar (380 °C) has been obtained from the white mica, K-feldspar and biotite-bearing rocks using an intersection of the reaction: 3Cel = Phl + 2Kfs + 3Qtz + 2H2O with the chlorite geothermometer. These results suggest higher temperature and lower pressure of Alpine low-grade metamorphism than previous estimates. The P-T conditions of Alpine low-grade metamorphism in the Veporic unit are in good agreement with observed deformational microtextures.

    ABSTRACT: Tectonic activity during the Miocene exhumation of the Tatra granitoid basement resulted in frictional melting of granite. The activity marks the early stages of the faulting that is responsible for uplift of the High Tatras. As indicated by pre-existing cataclasite metamorphic mineral assemblages, the ambient pressure was about 250–300 MPa, corresponding to depths between 10 and 12 km. The pseudotachylytes are Fe rich, highly oxidized and crystalline. The matrix composition suggests disequilibrium partial melting of a biotite-dominated assemblage. Oxygen isotopic compositions of a pseudotachylyte sample and its constituent minerals show equilibration with the host granodiorite and allow for the introduction of oxidizing external water rather than oxidation as a result of the dissociation of free water liberated during melting. The kinetic information extracted from hematite crystal-size distributions (CSDs) that are preserved in feldspathic matrices shows that crystals in most places were accumulated while the system was open. The melt was highly mobile and prone to strong differentiation. The hematite crystals reach a maximum of 26 vol. % (45 wt % Fe 2 O 3 ). In rare places where the flow ceased, the system became closed and produced distinct CSDs. The longest apparent crystallization times (90 s) are recorded mostly in pools in the central parts of the pseudotachylytes whereas the shortest times (10 s) come from rims and tips of fractures. The estimated hematite growth rate was about five orders of magnitude higher than that of ilmenite in lava lakes. Such extreme crystallization rates result from high undercoolings associated with high cooling rates. Very high cooling rates are promoted by the extremely high surface/volume ratios of the pseudotachylyte sheets.

    ABSTRACT: This study presents the first preliminary U-Pb zircon data on tin-bearing S-type granites from the Gemeric unit of the Western Carpathians (Slovakia). U-Pb single zircon dating controlled by cathodoluminescence suggests crystallization of the Gemeric granites during Permian to Early Triassic (303-241 Ma) time. Post-crystallization, low-temperature metamorphic overprint is reflected by partial Pb loss in zircons. These Gemeric granites are younger than the highly fractionated, S- type, tin- and rare-element-bearing leucogranites in the European Variscides. They may have resulted from partial melting, triggered by increased heat flow from the mantle below the continental crust, and most probably intruded during the post-collisional extension and initial rifting of the Variscan orogenic belt. During Alpine orogeny, the Gemeric granites were affected by a low-temperature deformation and metamorphism.

Acknowledgements 94 References 94 Abstract The West Carpathian Mesozoic sedimentary successions provide evidence about important pre-orogenic rifting events that generated subsiding basinal domains separated by submarine and/or subaerial highs. Since the geometry of rift-related fault structures can seldom be studied directly, the rifting process is reconstructed by interpretation of relative bathymetry/subsidence curves of individual sedimenta-ry successions. Five rifting phases, which represent climaxes of a long-termed extensional tectonic regime, can be distinguished: (1) the latest Permian -Early Triassic phase which was completed by the Anisian break-up of the Meliata Ocean; (2) the Early Liassic phase which was characterized by overall lithospheric stretching and wide rifting; (3) the restricted Late Liassic phase which manifested itself by extensional block tilting; (4) the Middle Jurassic asymmetric rifting which was terminated by the break-up of the South Penninic-Vahic ocean in the late Bajocian -early Bathonian and (5) the Early Cretaceous asymmetric rifting that led to the break-up of the North Penninic-Magura Ocean. The passive, asymmetric rifting mode is inferred in this study from distinctly different subsidence and/or uplift patterns of opposite margins of extended basinal domains. Further it is assumed that solely asymmetric rifting resulted in the break-up of the European continental lithosphere to generate the Penninic oceanic domains. Since rifting in the foreland of the lower plate occurred contemporaneously with advancement and shortening of the compressional orogenic wedge prograding from the hinterland Meliata suture, a common geodynamic scenario for simultaneous foreland extension and hinterland compression during one orogenic cycle is proposed in this study.
