Figure F40. Photomicrograph of a plagioclase-clinopyroxene glomerocryst in Unit 5 containing chromite inclusions (small dark gray inclusions at center right and the diamond-shaped inclusion in the upper left). These do not have the characteristic blue-gray color of Cr spinel (Sample 197-1206A-15R-3 [Piece 15, 87-89 cm]) (reflected light; field of view = 1.25 mm; photomicrograph 1206A-325).
