Generalised stratigraphy and facies of the Jura Molasse. The blue dashed rectangle illustrates the succession penetrated in the Tramelan-2 borehole. Adapted from unpublished figure courtesy of and with kind acknowledgment to Dr. Damien Becker (2022 unpublished data). Molasse Basin lithostratigraphy adapted after Keller (1992) and Sommaruga (1996). See Pirkenseer et al. (2018) for alternative stratigraphic synthesis and correlations with the URG. Chronostratigraphic ages are from Cohen et al. (2022)
