Figure F27 (continued). E. Intergrown oxides and sulfides (black) surrounded by brown amphibole (dark gray), in between clinopyroxene with some intergrown amphibole (bottom) and plagioclase (top; Sample 176-735B-94R-3, 119-121 cm), in plane-polarized light. Field of view = 0.7 mm. F. Same as E, except photographed in combined transmitted and reflected light. With reflected light, the opaque clump is seen to consist of sulfides (light gray) and ilmenite (darker gray). The smooth sulfide is pyrrhotite. The more irregular sulfide at center right is chalcopyrite.
