Overview map of the Northern Alpine Foreland Basin (a) by Schori (2021) located in France and Switzerland (b). The tectonic units of the detached Northern Alpine Foreland Basin (NAFB) consists of the Swiss Molasse Basin (Plateau and Subalpine Molasses), the Jura Fold-and-Thrust Belt (FTB), The Ferrette Zone (FZ) and, the Vorfaltenzone (VZ). The tectonic units are fault bounded by thrusts and main faults except for the erosive boundary between the Plateau Molasse and the Internal Jura. The Autochtonous Northern Alpine Foreland (NAF) consists of: the La Serre Horst (LSH), Île Crémieu (IC), the Massif Central, the Bresse Graben, the Haute-Saône Plateau, the Upper Rhine Graben, the Vosges Massif, and the Black Forest Massif. the Prealpine Klippen, the Subalpine, Helvetic and Ultrahelvetic nappes, and the External Crystalline Massifs (ECM) including the Belledonne Massif (BE), the Mont-Blanc Massif (MB), the Aiguilles Rouges Massifs (AR), the Aar Massif (AM) and the Gotthard Massif (GM) comprise the External Alps. The study area zoomed in Fig. 2, includes the Geneva Basin and the Internal Jura. The Western Alpine transect (c) modified after Deville and Sassi (2006) and Schori (2021) represents the tectonic units in section view. C.N. Crêt de la Neige summit, G.F. Gros-Foug ridge
