Formation mechanism and evolution process of copper-rich porphyry magma
富铜斑岩岩浆形成机制与演化过程

Porphyry copper deposits, as one of the most important copper deposits in the world, play a vital role in modern economic and science. Since Schwartz (1947) firstly defined "Porphyry copper deposit", geologists had paid great attentions on it. Proceedings on formation mechanism and evolution process of porphyry copper deposits show that formation of copper-rich porphyry magma involved a series of processes as follows: formation of ore-bearing magma related to subduction of oceanic crust or detachment of continental lithospheric crust, crystallization and fractionation of magma and enrichment of ore-forming fluids and material in median magma chamber, crystallization and solidification of ore-rich porphyry magma in shallow crust, interaction between ore-rich porphyry magma and ambient rocks. Porphyry copper deposits were final products of the "product line". Finally, some hot topics of origin of porphyry copper deposits and ore-forming magma were discussed in this contribution.
