Structural and geological map of the Cuney area (for location, see Fig. 3), showing the position of the RCSZ with respect to the other units. The Combin Zone is made of a stack of units of oceanic provenance, separated by the Pancherot—Cime Bianche—Bettaforca Unit. In the RCSZ, the location of the pre-Alpine meta-sediments studied by Manzotti et al. (2012) is indicated by a brown star (north-east of the Col de Chaleby). In the Arolla Series, pods of variable size (from metre to hundreds of metres), preserving a Permian undeformed granitoid, is found southwest of Rifugio Cuney and in the Punta di Tsan—Punta di Chavacour area. Foliation traces associated with stages 3 and 4 are drawn as lines with one and two dots, respectively. Foliations in the Valpelline Series, represented as white traces, are related to the pre-Alpine evolution
