Figure F192. A. Weakly developed serpentine foliations dipping moderately in olivine gabbro (Sample 305-U1309D-90R-3, 3–18 cm). B. Olivine-rich troctolite with locally strong serpentinization foliation (Sample 305-U1309D-140R-2, 102–122 cm). Alteration veins crosscut the serpentine foliations, but some serpentine foliation also crosscuts the veins. Late, irregular, brittle veins occur with talc infills. C. Troctolite with intense serpentine foliation (Sample 305-U1309D-110R-4, 105–128 cm). Plagioclase grains show intense sets of microcracks subparallel to the adjacent serpentine foliation in olivine.
