2024130· Copper porphyry deposits are geological formations renowned for their abundant copper and long mine lives. Here are 15 of the largest copper porphyry resources in the world.
723· Porphyry copper ore-forming intrusions are distinguished from barren arc magmas by high oxidation state and “adakitic” high Sr/Y and La/Yb. Controversy over petrogenesis of adakites has centered on ambiguities in interpretation of their steep rare earth element (REE) patterns, and on whether garnet participates in their petrogenesis. Lambda (λ) …
2019531· Here, the arc crust is thick (> 45 km). 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.
20241018· Porphyry copper deposits (PCDs) supply the majority of the world’s copper (Cu) as well as significant amounts of molybdenum (Mo) and gold (Au). The formation of these deposits is controlled by a variety of geological factors, among which the magmatic oxidation is one of the focuses of current research. This study investigates the redox characteristics of arc …
