Figure F179. A. Rare evidence of deformation in a dark green vein, which consists of amphibole and plagioclase, within olivine gabbro (Sample 305-U1309D-89R-2, 130–133 cm) (plane-polarized light; field of view [FOV] = 5.5 mm). A tiny open crack with chlorite infilling occurs in the center of the vein. B. Same as A; cross-polarized light. C. Subvertical pale green vein with epidote, chlorite, and actinolite infillings cut by a subhorizontal white vein with prehnite and chlorite infillings within troctolite (Sample 305-U1309D-104R-3, 33–36 cm) (plane-polarized light; FOV = 5.5 mm). D. Same as C; cross-polarized light.
