Here we can observe the most classic mylonites of the Ferriere-Mollières shear zone. Medium grained dark-green mylonitic schist (fig. 4a) made up of quartz, K-feldspar and plagioclase porphyroclasts in a fine grained biotite and white mica matrix (fig. 4b). Sometimes garnet porphyroclasts are present. The amount of matrix is nearly 75%. Both at the meso…

Here we can observe the most classic mylonites of the Ferriere-Mollières shear zone. Medium grained dark-green mylonitic schist (fig. 4a) made up of quartz, K-feldspar and plagioclase porphyroclasts in a fine grained biotite and white mica matrix (fig. 4b). Sometimes garnet porphyroclasts are present. The amount of matrix is nearly 75%. Both at the meso and micro scale kinematic indicators are well recognizable. They are mainly represented by rotated porphyroclasts, S-C’ fabric, micafish and quartz oblique foliation representing a top-to-the SE sense of shear.
