Figure F188. Examples of cataclastic deformation fabrics. A. Cataclastic/breccia zones (interval 304-U1309B-16R-1, 39–51 cm). B. Breccia in basalt unit (interval 304-U1309B-4R-1, 10–26 cm). C. Breccia formed at greenschist grade (Sample 304-U1309B-16R-1, 31–33 cm) (cross-polarized light; field of view [FOV] = 8 mm). D. Brittle shear bands cutting across mylonite (Sample 304-U1309D-29R-2, 131–133 cm) (gypsum plate; cross-polarized light; FOV = 8 mm). (Continued on next page.)
