Fig. 12From: Schistes Lustrés in a hyper-extended continental margin setting and reinterpretation of the limit between the Mont Fort and Tsaté nappes (Middle and Upper Penninics, Western Swiss Alps)a Bedrock map of the Evolène area (Hérens valley); compiled after data from this study and existing maps (Moix and Stampfli 1980, 1981; Schneider 1982; Escher 1988; Allimann 1990; Kramar 1997; Steck et al. 1999; Sartori and Epard 2011; Glassey 2013; Marthaler et al. 2020a; Swisstopo Geocover); background altitude model ©Swisstopo; locations of the stratigraphic columns of Fig. b are indicated in green. b Characteristic lithostratigraphic successions through the base of the Série Rousse along the Hérens valley; scales differ between the stratigraphic columns (grey strokes represent ca. 20 m); triangles indicate breccia levels; circles, conglomerates; black points, detrital quartz; black dashes, dark calcschists; black lines, black schists; brown line, hardground.
