Supracrustal intraplate thickening of Variscan basement due to Alpine foreland compression: results from the superdeep well KTB (Bohemian Massif, Germany)

A kinematic/geometric model for the late- to post-Variscan period at the western border of the Bohemian massif was discussed. The faults and mineralized tension gashes studied revealed the deformation stages, namely, Upper Carboniferous subvertical tension gashes, Upper Carboniferous reverse faults, Cretaceous subhorizontal tension gashes and reverse faults and Neogene normal faults. The Franconian Lineament was also found to play an important role in the lithosphere's strength and in the interplate compression strain localization.
