Fabric and microfabric of the Saraillé crust-mantle detachment: the damage zone at sites of samples SAR2a, SAR2b and BCOR329 (road to Col de Saudarie, see Fig. 4 for localization). A. Serpentinized and talcified sheared mantle (samples SAR2a, SAR2b). B. Thin section of sample BCOR329c. Note the clasts of Paleozoic material (pal.) mixed with talcschist fragments in a talc-rich gouge. C. Tectonic lenses at site of sample BCOR329c. D1 and D2. The upper limit of the damage zone corresponds to the boundary with the Variscan material. It is observed west of the serpentine quarry, close to Col de Saudarie. Note the sharp contact with the underlying crustal gneisses (dip of contact: N10E35).
