Reconstructed T-t paths of the Polinik, Strieden, Gaugen and Goldeck complexes and proposed timing of activity of major shear zones during the Variscan, Permian and Alpine events. The age data are based on literature data (see text) and, in case of the Rb-Sr biotite data, on own data. The numbers in brackets refer to the detailed description in the text. It is assumed that the Gaugen Complex is split into two blocks divided by the Lessnigbach Shear Zone. The northern block resided at greater depth before exhumation along the Lessnigbach Shear Zone in the Late Cretaceous. The Proto-Lessnigbach Shear Zone represents a strike-slip shear zone that was probably active in the Late Jurassic. Permian sediments appear within this shear zone further west. The Polinik Complex was rapidly exhumed by the Wallner Shear Zone in the Late Cretaceous (Lb Lessnigbach, Bl Blassnig, Wa Wallner, SZ Shear Zone)
