Optical image of the deformed water-added sample. a Image of the entire sample (cross-polarized light). The compression direction (σ1) is shown by an arrow. Transparent parts can be seen at the upper and lower sample boundaries, the edge of the sample column, and around the fractures with a width of ca. 200 μm. Bulging can be recognized at the lateral sample boundaries. Rectangles denote the locations for enlarged images (b) and (c). b Bulging part (plane-polarized light). c Sample boundary and upward fracture (cross-polarized light with a gypsum plate). The sample boundary (a few tens of μm) is especially dusty, which is related to the formation of zoisite (Fig. 6)
