The deforma tional history of the Triassic south of the Inn Valley is characterised by six stages: (1) Thinning by top SE extension during Jurassic continental breakup, (2) stacking of thinned slices by top NW thrusting during the time of peak tem perature metamorphism at 140 Ma (Early Cretaceous), (3) postmetamorphic top SE extension (Late Cretaceous) con temporaneously with Gosau sedimentation on top of the nappe pile of the Northern Calcareous Alps and (4) a long period of N-S compression (Eocene), resulting in northvergent thrusting and folding with development of a foliation , southvergent thrusting and, finally, overturning of the strata In the western part of the investigated area. -

Hummocky Karren Lukas Plan1, Christa Renetzeder2, Rudolf Pavuza3, and Wilfred Körner4
International Journal of Speleology 41 (1) 75-81 Tampa, FL (USA) January 2012 Available online at scholarcommons.usf.edu/ijs/ & www.ijs.speleo.it International Journal of Speleology Official Journal of Union Internationale de Spéléologie A new karren feature: hummocky karren Lukas Plan1, Christa Renetzeder2, Rudolf Pavuza3, and Wilfred Körner4 Abstract: Plan L., Renetzeder C., Pavuza R. and Körner W. 2012. A new karren feature: hummocky karren. International Journal of Speleology, 41(1), 75-81. Tampa, FL (USA). ISSN 0392-6672. http://dx.doi.org/10.5083/1827-806X.41.1.8. Karren are small-scale landforms on karst surfaces and many types have been described so far. Here we present an apparently new feature which was found on the Hochschwab karst massive in the Northern Calcareous Alps of Austria. So far only few outcrops each having less than 1 m² within a very restricted area have been found. Morphometric analysis reveals that the karren consist of a randomly distributed, dispersed assemblage of small hummocks and depressions in between. The mean distance between neighbouring hummocks is 4 to 5 cm and the mean height is 0.85 cm. Longitudinal sections are gently sinuous. The occurrences are delimited by thin soil cover with grassy vegetation and the karren continue below that vegetation cover. Therefore, it is clear that the features have formed subcutaneously. Corroded fissures where water could infiltrate into the epikarst are absent. The bedrock lithology is Middle Triassic limestone of the Wetterstein Formation in lagoonal facies. Geological structures do not govern the feature. The surface is not a bedding plane and small joints and fractures do not govern the arrangement of the hummocks. -

Acknowledgement 84 References 84 Abstract Published microthermometrical data of fluid inclusions, which were trapped near or subsequent to the time of maximum subsidence of the Drau Range (Eastern Alps) have been used to evaluate the relationship between fluid flow and heat transfer. The evaluation is based on a numerical 1-D heat flow model, calibrated with vitrinite reflectance values. Aqueous fluid inclusions in quartz fissures crosscutting Permo-Scythian sediments and in fluorites hosted by Carnian carbonates give evidence for conductive heat transfer during fluid flow in the Late Cretaceous/Neogene. This implies that trapping temperatures of these fluids (125 °C to 220 °C in quartz, 115 °C to 180 °C in fluorite) can be used to approximate the burial temperatures (190 °C in the Permo-Scythian, 130 °C to 150 °C in the Carnian). -

Age and Evolution of the Wetterstein Carbonate Platform in SW Serbia (Zlatibor Mountain)
Further research is necessary to understand the relationship between the gold-bearing mineralizations and their settings.

These slides occur tectonically on top of the Drina-Ivanjica Palaeozoic and the late Middle to early Late Jurassic ophiolitic mélange respectively the ophiolites and not below as interpreted before. These slides were interpreted to derive from the Drina-Ivanjica Unit, where they should have formed the original sedimentary cover, disintegrated in the Late Jurassic. According to our investigations the slides of this carbonate-clastic mélange differ in age, facies and palaeogeographic origin. The carbonate rocks are originated from a relatively broad shelf in the Triassic facing the Neotethys Ocean to the east, maybe also from the adjacent Drina-Ivanjica Unit and from further east. -
Middle Triassic Evolution of the Northern Peri-Tethys Area As Influenced by Early Opening of the Tethys Ocean
Annates Societatis Geologorum Poloniae (2000), vol. 70: 1-48. MIDDLE TRIASSIC EVOLUTION OF THE NORTHERN PERI-TETHYS AREA AS INFLUENCED BY EARLY OPENING OF THE TETHYS OCEAN Joachim SZULC Institute o f Geological Sciences, Jagiellonian University, Oleandry Str. 2a, 30-063 Cracow, Poland, E-mail: szulc@ing. uj. edu.pl Szulc, J., 2000. Middle Triassic evolution of the northern Peri-Tethys area as influenced by early opening of the Tethys Ocean. Ann. Soc. Geol. Polon., 70: 1-48. Abstract: During Middle Triassic times, the Germanic or northern Peri-Tethys Basin pertained to the western Tethys Ocean. The basin was closed from the north and open toward the Tethys by tectonically controlled depressions (gates). The gates were opened in different times. The marine incursions broke first (as early as in late Scythian time) through the eastern gates and from the Polish Basin advanced gradually to the west. Semiclosed disposition of the basin resulted in its distinctive environmental diversification. Open marine environments developed along the southeastern margins which should be regarded as an integrate part of the Tethys Ocean rather than the epicontinental sea. Northward and westward from the Silesian and Carpathian domains the environments became more restricted. This resulted in significant facies diachronity between the western and eastern parts of the basin. As indicated by the faunal diversity, facies variability and geochemical properties of the sediments, during almost entire Anisian time the open marine sedimentation dominated in the eastern part while the western part displayed restricted circulation, typical for the semi-closed, evaporitic basin. The circulation reversed in Ladinian time when the westward shift of the tethyan spreading center gave rise to opening of the western gate. -
Role of High-Angle Faults During Heteroaxial Contraction, Inntal Thrust Sheet, Northern Calcareous Alps, Western Austria
Festschrift zum 60. Geburtstag von Helfried Mostler Geol. Paläont. Mitt. Innsbruck, ISSN 0378-6870, Bd. 20, S. 389^06 ROLE OF HIGH-ANGLE FAULTS DURING HETEROAXIAL CONTRACTION, INNTAL THRUST SHEET, NORTHERN CALCAREOUS ALPS, WESTERN AUSTRIA Gerhard Eisbacher & Rainer Brandner With 7 figures Abstract: During Late Cretaceous/two-stage contraction of sedimentary strata within the Austroalpine accretionary wedge initial fold-thrust detachment and subsequent heteroaxial shortening were controlled by low-strength stratigraphie heterogen- eities and by the propagation of transverse high-angle faults. For the Inntal thrust sheet of the Northern Calcareous Alps (NC A) about 20 km of NW-directed thrust movement was accompanied by internal shortening and by distributed dextral displacement along NW-striking transfer faults by about 15 to 20 km. Thrust sheet segmentation along high- angle transfer faults led to significant relief between stratal panels of variable vergence and accounts for local depositi- on in and patchy preservation of Upper Cretaceous syndeformational clastic basins. One of the authors (R.B.) inter- prets orogen-parallel striking normal faults with Upper Cretaceous scarp breccias as an indication of today's NW-SE extension of the early alpine nappe edifice. Superimposed NNE-SSW-oriented heteroaxial contraction in latest Cretaceous-Paleogene time by about 10 km reac- tivated initial transfer faults as high-angle reverse faults, with a new set of NE-striking high-angle sinistrai faults pro- pagating from the footwall into the frontal Inntal hangingwall. This increased the plunge of pre-existing folds and pro- duced a new set of plunging folds within fault-bounded panels. High-angle faults thus accommodated polyphase shor- tening of the NCA-wedge and superimposed basins that formed along transverse zones with major structural relief. -
