How to make porphyry copper deposits ScienceDirect

Jan 01, 2020Like most ore deposits, porphyry copper deposits (PCDs) are rare, but they exhibit spatiotemporal patterns of distribution and geochemical signatures that may hint at their origins. They represent shallow level intrusives (2–5 km) ( Sillitoe, 2010 ), not too shallow that they erupt and not too deep that they do not degas ( Fig. 1 ).

Porphyry an overview ScienceDirect Topics

Porphyry deposits are large (from 100 million to several billion metric tons [t]), low-grade (0.2–1.5 wt% copper, < 0.01–0.3 wt% molybdenum, and < 0.01–1 g/t gold; Fig. 3), disseminated and breccia deposits commonly hosted both in granitoid intrusions and the overlying country rocks, and directly associated with granitoid porphyry dikes or plugs.
