Figure F7. Reflected-light photomicrographs of (A) Sample 169-856H-31R-2, 1-5 cm, from the Deep Copper Zone beneath Bent Hill Massive Sulfide deposit, (B) Sample 169-1035H-19R-1, 58-62 cm, from the Deep Copper Zone beneath ODP Mound, and (C) Section 169-856H-19R-1, at 94 mbsf, ~100 m higher in the stratigraphy than the Deep Copper Zone at the base of the massive sulfide deposit. The host mineral is isocubanite, and the lamellae are chalcopyrite.
