Figure F240. A. Poikilitic orthopyroxene (opx) containing small blebs of clinopyroxene in orthopyroxene-bearing gabbro from Unit 1256D-92 (Thin Section 113; Sample 312-1256D-232R-1, 97–100 cm) (field of view [FOV] = 2.4 mm; plane-polarized light). plag = plagioclase. B. Same as A; cross-polarized light. C. Fine recrystallized granoblastic orthopyroxene and clinopyroxene enclosing tiny rounded plagioclase grains (Thin Section 113; Sample 312-1256D-232R-1, 97–100 cm) (FOV = 2.4 mm; plane-polarized light). D. Same as C; cross-polarized light. Orthopyroxene can be distinguished from clinopyroxene (cpx) by the blue interference colors of the latter.
