What is a Porphyry Copper Deposit?

2015-6-27  porphyry copper deposits were the first type of metallic mineral deposit to be exploited by large-scale, bulk tonnage, open pit mining methods. Economies of scale and advances in technology have made it possible to profitably mine these deposits despite their relatively low ore grades.

2020-1-1  Much of the world's economic copper resources are hosted in porphyry copper deposits (PCDs), shallow level magmatic intrusions associated mostly with thick (> 45 km) magmatic arcs, such as mature island arcs and continental arcs.However, a well-known, but unresolved paradox, is that arc magmas traversing thick crust, particularly in continental arcs, are generally depleted in Cu whereas in ...

Copper was mostly removed from the sericitic capping, but iron, molybdenum, and gold were relatively immobile during supergene leaching.Interpretation of the space-time patterns and relations of the mineralization, alteration, volcanism, and intrusion allows reconstruction of the depositional environments of the El Salvador porphyry copper deposit.
