Fig. 1From: Lithofacies, stratigraphy and depositional history of Middle Muschelkalk evaporites (Zeglingen Formation) in northern SwitzerlandTectonic map of the study area showing the location of investigated boreholes. Black lines show cross-sections (A)–(C) shown on Figs. 11, 12, 13; Cross-section (C) extends 70.5 km further north to borehole Stetten-M outside of the study area. Geologic-tectonic units and tectonic structures follow Nagra (2014) and Schori (2021); Central North Swiss Permo-Carboniferous Basin follow Madritsch et al. (2018)Back to article page
