Tectonic map of the Tauern Window according to Schmid et al. (2013). See inset for location. The tectonic window consists of a metamorphic dome forming the core of large anticlines produced during collision of the Europen and Adriatic plates. The formation is coeval with orogen-parallel extension (e.g. Ratschbacher et al. 1991; Frisch et al. 2000). Several Tertiary plutons occur in the region of the right-lateral Periadriatic line.
