Geological setting. (A) Map showing the major alluvial fan systems (yellow) in the Swiss part of the North Alpine Foreland Basin (NAFB) with respect to the present-day thrust front of the Alps during Upper Freshwater Molasse (OSM) deposition. The Fontannen section is located in the proximal part of the Napf alluvial fan system, draining the Central Alps during the OSM phase (modified after ref. 24). Maps were generated using CorelDRAW Graphic Suits X5 (https://www.coreldraw.com/en/). (B,C) Typical paleosols of the NAFB with abundant pedogenic carbonate nodules.
