Comments on the geologic information

  • Geologic Description = At this mineral occurrence, one of several within the Halibut Bay ultramafic complex, chalcopyrite and pyrrhotite are present as disseminations in a 3-foot layer of gabbro. The gabbro layer lies between pyroxenite and peridotite. A sample of this material contained 1,700 ppm copper, 420 ppm nickel, 25 ppm cobalt, and traces of gold, silver, platinum, and palladium (Foley and Barker, 1985, table 14). ? the Halibut Bay ultramafic complex, consisting mostly of dunite, gabbro, pyroxenite, and peridotite, occurs within sedimentary units of the Uyak formation of Cretaceous age.
