• CSMS GEOLOGY POST: PEACOCK ORE; BORNITE OR CHALCOPYRITE?

    The sulfide bornite [Cu 5 FeS 4] is also an important copper ore (close to 65% by mass), especially in the copper porphyry deposits. It is Orthorhombic but commonly is massive and/or granular in habit. It does not display the brassy color of pyrite or chalcopyrite until tarnished but is a mottled brown/black/purple to copper-red but often is mixed with chalcopyrite. It easily tarnishes upon ...
