Figure F14. Gabbroic material in peridotites. A. Serpentinized dunite with intergranular gabbroic material now consisting of amphibole along grain boundaries and filling microcracks crosscutting olivine (interval 209-1271B-10R-1, 40–47 cm). B. Olivine gabbro with coarse oikocrystic texture enclosing schlieren of dunite and olivine xenocrysts (interval 209-1271B-18R-1, 20–26 cm). C. Troctolite enclosing dunite xenoliths and olivine xenocrysts (interval 209-1271B-16R-1, 24–30 cm). D. Serpentinized dunite with intergranular gabbroic minerals, mostly plagioclase with minor clinopyroxene, and crosscut by dikelets of gabbroic material (interval 209-1271B-19R-2, 1
