Geological evidence strongly supports the view that specific tectonic settings, magma compositions, and hydrothermal alteration conditions govern the formation of porphyry copper deposits.
The claim that specific geological conditions favor the formation of porphyry copper deposits is overwhelmingly supported by multiple peer-reviewed studies in economic geology and petrology. These papers detail the precise magmatic, tectonic, geochemical, and alteration controls (such as specific crustal depths, oxidation states, magma series, and fluid pathways) required for porphyry copper genesis. No retrieved papers refute the premise.
