Porphyry Copper Deposits Geology for Investors

Mar 01, 2021· Most of the world’s copper is extracted from a type of mineral deposit called a “porphyry copper”. If you’ve seen a picture of a great big open-pit mining operation odds are that it was a porphyry copper deposit. Some of the biggest man-made holes in the ground are porphyry copper mines: Bingham Copper Mine, Utah, and Chuquicamata in Chile, and two of the largest.

Exploration of Porphyry Copper Deposits

So how do we explore for Porphyry Copper Deposits which are completely covered by barren younger rocks? Well let’s back up a bit, we know that porphyries form under large subduction related volcanoes and that most of these are located under the ring of fire around the subducting pacific plate another fertile subduction zone occurs in Balkans, Turkey, Iran and Pakistan. So this gives us a

Reduced porphyry copper-gold deposits: A new variation on

Based on a synthesis of theoretical, experimental, and field data, a variation on the classic porphyry Cu model is proposed to explain the formation of reduced porphyry Cu-Au deposits and their relatively Cu-poor but Au-rich nature. The proposed reduced porphyry Cu-Au model does not contradict the current understanding of porphyry Cu-Au formation.

The formation of porphyry copper deposits SpringerLink

Copper is a moderately incompatible chalcophile element. Its behavior is strongly controlled by sulfides. The speciation of sulfur is controlled by oxygen fugacity. Therefore, porphyry Cu deposits are usually oxidized (with oxygen fugacities > ΔFMQ +2) (Mungall 2002; Sun et al. 2015). The problem is that while most of the magmas at convergent margins are highly oxidized, porphyry Cu deposits
