Gold abundances in porphyry copper deposits vary greatly, complicating efforts to define gold-rich porphyry copper deposits. The original definition was based on the Au/Mo ratios of porphyry copper deposits with no reference to their copper content, and resulted in the suggestion that gold-rich deposits were found largely in island arc regions (Kesler, ).Cited by: ume, Geology ofthe Porphyry Copper Deposits, Southwestern NorthAmerica, published in and edited by Titley and C.

Cited by: 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.
