FIG. 7. Photomicrographs showing the textures of sulfide minerals. A. Chalcopyrite (Ccp) along cleavage planes of actinolite (Act). The sample is from the medium-grained clinopyroxenite (2b) of the southern Roby zone. B. Primary magmatic sulfide bleb with apparent exsolution of chalcopyrite (Ccp) and pentlandite (Pn) in late fractures within pyrrhotite (Po). The sample is from the medium-grained melanocratic gabbro (2c) of the southern Roby zone. Note the thin lamellae of chalcopyrite along cleavage planes of actinolite (lower left).
