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.

  • 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.

The process of dynamic rock fragmentation is suggested to play a major role in the development of unusual long runouts, nevertheless, the processes are not yet fully understood and further studies of rock avalanche deposit features are required to obtain a deeper understanding of movement and emplacement dynamics.

  • Facies and Sedimentary Environments of the Upper Scythian–Carnian
    Annales Societatis Geologorum Poloniae (2005), vol. 75: 155-169. FACIES AND SEDIMENTARY ENVIRONMENTS OF THE UPPER SCYTHIAN-CARNIAN SUCCESSION FROM THE BELANSKE TATRY MTS., SLOVAKIA Tomasz RYCHLIŃSKI & Joachim SZULC Institute o f Geological Sciences, Jagiellonian University, Oleandry 2a, 30-063 Krakow, Poland; e-mail: [email protected], [email protected] Rychliński, T. & Szulc, J., 2005. Facies and sedimentary environments of the Upper Scythian-Camian succession from the Belanske Tatry Mts., Slovakia. Annales Societatis Geologorum Poloniae, 155-169. Abstract: The Triassic Fatricum basin studied in the Belanske Tatry Mts. (Slovakia) was a relatively stable and restricted platform area influenced by eustatic and climatic fluctuations. During the early Triassic the platform was influenced by continental clastic sedimentation intermittent with shallow marine transgressions when carbonate sediments formed. Common occurrence of carbonized plat debris suggests relatively humid climatic conditions dominating during this interval (Werfenian facies). Significant climate aridisation was concurrent with the beginning of the Middle Triassic transgression as indicated by evaporitic fabrics common within the entire Middle Triassic carbonate succession. The Middle Triassic has been divided into several lithofacies complexes reflecting the interplays between the eustatic and climatic fluctuations. The lower Middle Triassic complex (lower-middle Anisian?) displays dominance of calcareous sediments indicating free communication with the open ocean. The subsequent intervals are rather uniform facies assemblage composed by dolomites and evaporites formed in a restricted and stagnant basin. The basin has been strongly influenced by subtropical storms, particularly common in the late Anisian. Transgression pulse in the early Ladinian involved growth of microbial colonies building thrombolitic biostromes. Final shallowing by the end of Ladinian led to replacement of carbonate sediments by continental clastics of the Carpathian Keuper.

Quantitative palynological data from the 23 Mercia Mudstone Group in the Wessex Basin (UK), reveals vegetation changes and 24 palaeoclimate trends. Palynostratigraphy and bulk organic carbon isotope data enable 1 25 correlation to other Carnian successions. The palynostratigraphy indicates that the 26 Dunscombe Mudstone is Julian and the lowest part of the overlying Branscombe Mudstone 27 Formation is Tuvalian.. The Aulisporites acme characterizing the CPE in Tethyan successions 28 and the Germanic Basin, is missing in the UK. The quantitative palynological record suggests 29 the predominance of xerophyte floral elements with a few horizons of increased hygrophytes. 30 A humidity signal is not seen due to the dry climate in central Pangea.
