A series of cm- to m-spaced ENE-WSW-trending subvertical faults here are filled with cataclasite comprising fine angular (rare 10 mm, mostly <5 mm grain-size) fragments of altered protolith, weakly foliated in some cases, set in a cemented dark grey matrix (almost clay-sized, < 1 [micro]m) (Figure 3(a)).
