Porphyry copper deposits (PCDs) represent shallow level intrusions (2–5 km) in the crust. Mineralization of Cu ores tend to occur at the tops of porphyry systems in cupolas. Possible regimes where Cu may be mobilized include hydrothermal circulation at midocean ridge centers, dehydration or melting of the subducting slab, and late stage scavenging by magmatic fluids (green arrows).
