Plate 1. Selected key textural relationships in the high-grade schist. 1. D2 fold in a biotite-rich high-grade schist. Sillimanite and biotite define S2 parallel to the axial surface of the fold. Note on the lower left corner the early plagioclase porphyr

Plate 1. Selected key textural relationships in the high-grade schist. 2. Detail of a D₂ fold deforming S₁. S₁ is defined by garnet-rich and quartz-rich laminae. Garnet I porphyroblasts (G) have a typical skeletal and tabular shape. Sample 161-976E-14R-3, 0-4 cm. Plane-polarized light. Scale bar is 500 µm.
