p.21: Located east of the Rhine Graben, the South German Platform occupies the eastern part of the northern border of the map area. A major normal fault, the Schwarzwald Fault, separates both units. East of this fault, the Schwarzwald Massif exposes the basement of the South German Platform, which consists mainly of metamorphic and plutonic rocks (Schaltegger 2000), with some remnants of Late Paleozoic sediments (Nitsch 2018). The massif is characterized by WNW–ESE striking brittle faults, some of which can be traced further southeast into the Mesozoic overburden where they formed important precursor structures during Neogene deformation events (Egli et al. 2017).
