Porphyry copper deposit - Wikipedia

Porphyry copper deposits are copper orebodies 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 magmatic ....
