Abstract
The Chin Shan porphyry copper-gold deposit is located in the south of China in Fujian province. This is a large deposit containing more than 1000 t industrial reserves of gold and more than 0.5 mln. t of copper. It is related to a very complex polygenic and polychronic type of porphyritic plutonogenic hydrothermal deposits formed during the final stage of the formation of volcano-plutonic granite dioritic complex of the Cretaceous age. Later post-magmatic fluids of the Late Mesozoic (Kimmeridgian) epoch of tectonic magmatic activation also took part in ore formation. The gold-silver and polymetallic activation is related to precisely this epoch. The modern shape of the deposit and all industrial ores appeared in the Quaternary period during the formation of the unique extended oxidation zone.
