Two schematic cross-sections of the northern Dora-Maira Massif (modified from Manzotti et al., 2022). Tectonic boundaries are shown in red. The trend of the main, regional, foliation S2 is indicated by thin, dashed, lines. Kilometre-scale folding a previous schistosity S1 are indicative only, being recognized with certainty only in a few cases. A pre-Alpine foliation (thin red dashed lines) has been identified in a volume poorly deformed during the Alpine orogeny and located below the Punta Muret
