Location of the drill site

The village of Gaisbeuren lies at the southern end of the Tannwald Basin, an overdeepening that has presumably been eroded during the third-to-last Hosskirch Glaciation (Ellwanger et al., 2011; Ellwanger, 2015, see 5068_1 TANN).

There, another isolated basin (Gaisbeuren Basin) underlying the Tannwald Basin is presumed based on results from a previous but not anymore existing drill core, which is not unlikely to represent an early Middle Pleistocene glaciation (Ellwanger, 2015).

Due to the supposed exceptional stratigraphic position of the Gaisbeuren Basin, drilling was undertaken by the State Office for Geology, Resources and Mining of Baden-Württemberg (LGRB) in 2016.
