Figure F176. A. Dark green vein overprinted by cataclasis in gabbro (interval 305-U1309D-187R-1, 66–88 cm). Yellow box = location of B and C. B. Dark green vein associated with cataclasite (Sample 305-U1309D-187R-1, 69–72 cm) (plane-polarized light; field of view [FOV] = 2 cm). Yellow box = location of D. C. Same as B; cross-polarized light. Yellow box = location of E. D. Cataclastic zone along green vein (plane-polarized light; magnification = 7.5×). Also shown are fragmented plagioclase grains with alterationed mineral infilling. E. Same as D; cross-polarized light. Note the amphibole grains as fracture infilling with no deformation between fragmented plagioclase grains (arrow) apart from the cataclasite zone.
