Porphyry copper deposits are copper ore bodies that are formed from hydrothermal fluids that originate from a voluminous magma chamber several kilometers below the deposit itself.
1 de ene. de 2020 · 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 mid-ocean ridge centers, dehydration or melting of the subducting slab, and late ...
6 de jul. de 2021 · Porphyry deposits are large, low-grade metal ore bodies that are formed from hydrothermal fluids derived from an underlying magma reservoir. They are important as major sources of critical...
6 de may. de 2022 · In this study we focus exclusively on the syn-subduction Cu-rich porphyry copper deposit type (hereafter referred to as porphyry copper deposits), occurring in thick continental arcs.
Porphyry copper deposit, large body of rock, typically a porphyry of granitic to dioritic composition, that has been fractured on a fine scale and through which chalcopyrite and other copper minerals are disseminated. Porphyry copper deposits commonly contain hundreds of millions of metric tons of.
1 de feb. de 2016 · Porphyry copper deposits are large. They commonly consist of hundreds of millions to billions of tonnes of ore. However, they contain typically only 0.5–1.5% copper and are therefore classified...
5 de nov. de 2016 · Most porphyry copper (Cu) deposits are distributed along convergent margins (Fig. 1). A porphyry deposit is a semi-closed system that usually formed at depths of 2–4 km (Sillitoe 2010 ), but the controlling factors are still a topic of contention amongst scholars (Chiaradia 2014 ; Chiaradia et al. 2012 ; Cooke et al. 2005 ; Lee et ...
