Figure F36. Euhedral olivine phenocrysts and small, euhedral chrome spinel crystals with skeletal groundmass olivine (elongate brown crystals) in Sample 192-1185A-8R-1 (Piece 2, 15-18 cm), Unit 1. One of the olivine crystals is unaltered (middle left). The remaining groundmass is cryptocrystalline but contains smaller, skeletal olivine crystals just visible in this view (field of view = 1.4 mm; crossed polars; photomicrograph ID# 1185A_121).
