Figure F56. Dusky green basalt with olivine phenocrysts totally replaced by celadonite in Sample 192-1185B-22R-7 (Piece 2, 42-43 cm); the groundmass glass is slightly replaced by the same secondary mineral. Plagioclase and clinopyroxene are unaltered (overall alteration = 3%-5%; field of view = 1.4 mm; plane-polarized light; photomicrograph ID# 1185B
