Representative field photographs of the “Cévennes schists”: (a) metapelitic chlorite–muscovite schist (44.5028°N, 4.1213°E); (b) schist with fine alternations of quartz-rich (poorly foliated) and quartz-poor domains (44.5833°N, 4.0545°E), likely derived from a semi-pelite protolith; (c) schist typified by layers rich in mm-sized albite porphyroblasts (44.5924°N, 3.9745°E); (d) dark (biotite-bearing) quartz schist, a facies primarily encountered close to the Cézarenque–Joyeuse gneisses (44.3937°N, 4.0781°E).
