in particular the abundance of isocubanite and chalcopyrite was significantly higher in the Deep Copper Zone than had been reported from any part of the massive sulfide body. The massive sulfide at Bent Hill is predominantly pyrite and pyrrhotite, with much lower abundance of sphalerite, chalcopyrite, and magnetite (Fig.

There are steep min-eralogical, chemical, and isotopic alteration gradients from the highly altered basalt-sediment interfaces down to the less altered flow interiors, suggesting the channeling of hydrothermal fluids along the ...
