Geological map showing the Schobergruppe (SG) within the tectonic framework of the Eastern Alps (a) and in more detail with sample location (b) (modified after Schulz et al. (2005, 2008). (c) Distribution of K–Ar and Rb–Sr mica ages to the south of the Tauern Window (compiled from Borsi et al. (1978); Hoinkes et al. (1999); Schuster et al. (2001)). Cross section through the Schobergruppe and Prijakt eclogitic amphibolites (d) and through the Austroalpine basement to the south of Hopfgarten (e). Sample locations and Th–U–Pb chemical ages of monazite are also shown
