Scientific focus (keywords): metamorphic petrology; Eastern Alps; tectonic structure; tectonic windows; polymetamorphism; Austroalpine continental crust; Cretaceous collision; eclogite type locality; Penninic oceanic crust; Tertiary subduction; geochronology; geothermobarometry

Photo: The Alpine Orogene of Central Europe developed during the Cretaceous to Neogene convergence of Apulia and Europe. Due to a complex paleogeography with several terranes and oceanic embayments of the Alpine Tethys Ocean in between these two continental plates, the tectonic evolution of the Alps is not entirely understood and several aspects are still under discussion. The route of the excursion passes through nearly all major tectonic units of the Eastern Alps and will also give a representative overview on the different landscapes, including the intramontane Pannonian Basin, the hilly areas of the easternmost Eastern Alps, the mountainous regions of the Hohe Tauern, the Northern Calcareous Alps and the frontal Molasse Basin. The visited outcrops will give insight into the polyphase metamorphic history (Carboniferous, Permo-Triassic, Cretaceous and Tertiary) of the individual units. The program includes HP-metamorphic rocks from tectonic windows of the Penninic nappes derived from the subducted Alpine Tethys Ocean in the Tertiary, as well as from Austroalpine cover units derived from eo-Alpine intracontinental collision - subduction within the Apulian Plate in the Cretaceous.
