Figure F33. Photomicrograph showing amphibole-bearing dunite with a crosscutting relationship between early serpentinization of olivine and later alteration of the former gabbroic dikelets to an assemblage of chlorite-sericite-amphibole (Sample 209-1271B-10R-1, 40–43 cm) (cross-polarized light: blue filter; field of view = 5.5 mm; image 1271B
