Abstract During the TRANSALP project, deep seismic surveys and accompanying geophysical and geological projects were carried out to better understand the deep structure of the Eastern Alps south of Munich. The TRANSALP field trip series roughly follows the route in three parts: the Tauern Window, the Northern Calcareous Alps and its foreland, and the Southern Alps including the Dolomites. In this Tauern Window field trip, we will visit most of the geologically important sites along the middle part of the traverse or in its vicinity. The main topics covered in the Tauern Window will be the early Alpine paleogeographic situation on an extending European continental margin, Alpine nappe stacking and ductile rock deformation, metamorphism, uplift modes and exhumation, lateral escape, and the Brenner normal fault.
