Optical microscope images (a, b) and scanning backscattered electron images at different magnifications (ce) of the highly deformed clay-rich sediment from the fault core zone S V 1 shear vein 1 (first stage of deformation), S V 2 shear vein 2 (second stage of deformation), E V 2 Extension vein 2, Cal calcite, Py pyrite, Chl chlorite, Ilt Illite, Qz quartz. On the SEM images the cleavage is underlined by white dashed lines, the shear veins by black dashed lines on image c. The arrows indicate the sense of shear
