Gold in porphyry copper deposits: its abundance and fate
2002-10-1 1.. IntroductionPorphyry copper deposits contain up to 100 t of gold and are among the largest reservoirs of gold in the upper crust (Kerrich et al., 2000).They are commonly surrounded by deposits and country rock containing gold that is thought to have been derived from them (Jones, 1992).Gold can be removed from porphyry copper systems by vapors that

Gold in porphyry copper deposits: its abundance and fate
Cu/Au atomic ratios of porphyry copper ore deposits form a continuous range from about 5000 to 5,000,000 with a median near 40,000, which separates gold-rich and gold-poor deposits. Gold is found in porphyry copper deposits in solid solution in Cu–Fe and Cu sulfides and as small grains of native gold, usually along boundaries of bornite.
