Preliminary Model of Porphyry Copper Deposits

The general attributes of porphyry copper deposits are summarized below. Brief Description In hypogene parts of porphyry copper deposits, the copper occurs predominantly in chalcopyrite; other important copper ore minerals may include bornite and enargite. Ore minerals occur as disseminations and in stockworks of veins in hydrother-

A Tectonic Model for the Spatial Occurrence of Porphyry

porphyry copper deposits are most commonly located at the corners, and occasionally along the edges, of strike-slip fault duplexes, and the few polymetallic vein deposits identified are located at interior sites of the duplexes. In the second area, the model accounts for the preferred sites of porphyry copper and

Porphyry-style mineral-ization is confined to a large stock, ∼2km in diameter, composed of quartz diorite, amphibole plagioclase diorite and porphyritic varieties, which belong to the Birgilda-Tomino Igneous Complex.

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
