Figure F32. A. Large orthopyroxene (opx) oikocryst containing tiny inclusions of granular clinopyroxene, typical for Gabbro 2 (Unit 1256D-91). Note abundant dusty spots in plagioclase (plag) suggest that these grains are secondary, incorporating earlier altered material (Sample 312-1256D-230R-1, 36–40 cm; field of view (FOV) = 0.6 mm; plane-polarized and cross-polarized light). B. Poikilitic orthopyroxene containing small blebs of clinopyroxene in orthopyroxene-bearing gabbro (Unit 1256D-92), the central, orthopyroxene-bearing part of Gabbro 2 (Sample 312-1256D-232R-1, 97–100 cm; FOV = 2.4 mm; plane-polarized and cross-polarized light).
