Figure F73. Sample 304-1309D-10R-1, 91-94 cm (cross-polarized light). A. Serpentinized olivine (ol) with pyroxene (px) in lherzolite with evidence of melt impregnation as interstitial plagioclase (plag) (field of view [FOV] = 5 mm). B. Troctolitic area with olivine altered to talc and plagioclase altered to chlorite (gypsum plate; FOV = 5 mm). C. Altered pyroxene oikocryst with olivine chadacryst and interstitial plagioclase (altered to chlorite) (gypsum plate; FOV = 5 mm). D. Altered plagioclase interstitial to olivine (gypsum plate; FOV = 2.5 mm). E. Fresh clinopyroxene with vermicular intergrowth of plagioclase (FOV = 1.25 mm). F. Clinopyroxene with plagioclase bleb (cpx1) corroded by another clinopyroxene (cpx2) (FOV = 1.25 mm); note the olivine inclusion.
