Figure F16. Olivine phenocrysts partially altered to brown smectite but with unaltered interiors in Sample 192-1187A-6R-6 (Piece 2C, 105-107 cm). The groundmass consists of radiating elongate plagioclase laths and small interstitial crystals of clinopyroxene. This thin section was taken from the center of a pillow (field of view = 2.8 mm; crossed polars; photomicrograph ID# 1187A
