Figure F101. Modes of occurrence of oxide gabbro. A. Diffuse boundary between coarse-grained gabbro, oxide gabbro, and oxide concentrations (interval 305-U1309D-127R-3, 74–99 cm). B. Oxide concentration at the boundary with coarse-grained gabbro (interval 305-U1309D-244R-2, 102–111 cm). Arrow represents the zone of oxide concentration in this sample. C. Sharp boundary between olivine gabbro and oxide gabbro (interval 305-U1309D-114R-1, 41–56 cm).
