Porphyry-Cu hydrothermal systems - LinkedIn

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. Predating or associated with those fluids are vertical dikes of porphyritic intrusive rocks from which this deposit type derives its name. In later stages, circulating meteoric fluids may interact with the magm… WebPorphyry systems formed in such settings range to more alkaline compo-sitions and may be Au rich, leading to alkaline ... magmatic-hydrothermal Cu ± Au deposits (Richards, 2009).
