Figure F134. A. Carbonate vein cutting contact between olivine-bearing gabbro and olivine-rich troctolite (interval 304-U1309D-60R-2, 34–45 cm). B. Detail of A. Carbonate-talc alteration of diopside with tremolite (Trem) rim (cross-polarized light; field of view [FOV] = 1.25 mm). Px = pyroxene. C. Chlorite (Chl) pseudomorph after plagioclase in olivine-rich troctolite that has otherwise been altered to talc + carbonate (Carb) (cross-polarized light; FOV = 1.25 mm). D. Carbonate vein, possibly aragonite, that has partially inverted to calcite, cutting serpentinite (Sample 304-U1309D-31R-1, 16–19 cm) (cross-polarized light; FOV = 5 mm).
