copperporphyry
Copperporphyry refers to a type of porphyry deposit that is a major source of copper. These deposits are characterized by their large size and the presence of copper-bearing minerals, primarily chalcopyrite, disseminated within a granitic or granodioritic host rock. The term "porphyry" describes the texture of the rock, which contains larger crystals (phenocrysts) embedded in a finer-grained groundmass. In copperporphyry deposits, these phenocrysts are often feldspar and quartz, while the groundmass is also composed of these minerals along with micas and amphiboles.
The formation of copperporphyry deposits is linked to the emplacement of shallow-to-intermediate depth magmatic intrusions, typically
Copperporphyry deposits are economically significant due to their vast tonnage and relatively low but consistent grades
