Figure F236. A. Two olivine (ol) crystals (left edge above center; center of upper right quadrant) coexisting with orthopyroxene (lower left quadrant) in orthopyroxene (opx)-bearing oxide gabbro from Unit 1256D-89 (Thin Section 92; Sample 312-1256D-223R-2, 39–41 cm) (field of view [FOV] = 4.5 mm; plane-polarized light). Both phases are heavily altered. B. Same as A; cross-polarized light. C. Brown, flaky pargasite surrounding Fe-Ti oxide in orthopyroxene-bearing oxide gabbro in Unit 1256D-89 (Thin Section 93; Sample 312-1256D-223R-2, 57–60 cm) (FOV = 1.2 mm; plane-polarized light). D. Microgranular domain of metamorphic plagioclase and greenish clinopyroxene (with numerous inclusions of tiny oxide spots) in orthopyroxene-bearing oxide gabbro, Unit 1256D-89 (Thin Section 93; Sample 312-1256D-223R-2, 57–60 cm) (FOV = 1.2 mm; plane-polarized light). E. Intrusive contact between medium-grained gabbro of Unit 1256D-89a and coarse-grained disseminated oxide gabbro of Unit 1256D-89b (Thin Section 94; Sample 312-1256D-223R-2, 101–105 cm). Unit 1256D-89a is cut by Unit 1256D-89b. Comb layering is produced by crystal growth perpendicular to the margin of Unit 1256-89b.
