Porphyry Copper Systems1 | Economic Geology
Porphyry Cu systems are initiated by injection of oxidized magma saturated with S and metalrich, aqueous fluids from cupolas on the tops of the subjacent parental plutons The sequence of alterationmineralization events charted above is principally a consequence of progressive rock and fluid cooling, from >700° to <250°C, caused byPorphyry copper deposits are typically verylow grade with between 04 and 1% copper The main mineral is chalcopyrite, which is finelyPorphyry Copper Deposits | Geology for Investors
