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).
