Reverse Osmosis contributing to metal zoning in porphyry type deposits: A case study
Representing the main source of copper in the world, porphyry copper deposits have been widely studied. Different models have tried to explain the observed metal zoning, but they did not completely explain it. A Permian Cu-Mo porphyry deposit in the San Rafael Massif in Argentina shows a similar met...

Representing the main source of copper in the world, porphyry copper deposits have been widely studied.
