Geothermometry by Raman spectroscopy of carbonaceous material (RSCM) in the Schistes Lustrés and adjacent lithologies across Hérens valley and surrounding areas of SW Switzerland and NW Aosta valley (IT). a RSCM temperatures [°C] across Hérens valley: data from this study (circles) compared with available data from the literature (squares and triangles); background map from Fig. 1b. b RSCM temperatures [°C] across Hérens valley plotted on a geological cross-section constructed through the area (modified after Escher 1988; Escher et al. 1988, 1993, 1994); location indicated in Fig. a. c RSCM temperatures [°C] at regional scale: literature data (squares, pentagons and triangles) and data from this study (circles); background map from Fig. 1b (SE zone modified after Steck et al. 1999, 2015; Dal Piaz et al. 2015). d RSCM temperatures [°C] from Figs. a-b (Hérens valley) plotted against the distance of the outcrops to the contact between the Série Rousse (SR) and the Série Grise (SG); distances are calculated orthogonally to the mean local orientations of the structures (cf. Additional file 3); °T error bars: 1σ; Dist. error bars: 75%
