Geology of Gold Mineralization How Gold Deposits are Formed

The Geology Of Gold. Gold is relatively scarce in the earth, but it occurs provide a modern analog for these gold-depositing systems. Most of the water in geothermal systems originates as rainfall, which moves downward through fractures and permeable beds in cooler parts of the crust and is drawn laterally into areas heated by magma, where it is driven upward through fractures. As the

Porphyry-Related Deposits are formed in the epicrustal volcanic environment and constitute a principal source of copper-gold-molybdenum. Shallow porphyry intrusives, stockworks and breccia systems form large tonnage (up to several billion tons) low-grade deposits amenable to low-cost bulk mining and treatment. They are generally one to ten

Porphyry Copper Gold Deposit Model Porphyry deposits are the world's most important source of Cu and Mo, and are major sources of Au, Ag, and Sn. They account for about 50 to 60% of world Cu production and more than 95% of world Mo production. Porphyry deposits are large, low- to medium-grade deposits in which primary ore minerals are dominantly structurally controlled and which are
