East Asia,and especially China,was influenced by the Paleo-Asian,Tethys,and Pacific geodynamicsystems.This area is characterized by micro-continental blocks, many suturebelts and polycyclic subduction-collision zones and soft-collision of these components has resulted in overlapping orogenic belts and polycyclictectonic-magma-mineralization. In the Mesozoic, subduction of the Tethys, Pacificand Mongolia-Okhotsk plates and collision with North/South China Cratons formedthe passive continental margin in east China. Yanshanian movement is the mostimportant geological event in the east of China since the Mesozoic, resultingin the formation of complex tectonic-magma-mineralization.

The Central Asian, Tethyan and PacificMetallogenic Domains, located in the north orogenic belt of China and in nearbycountries, host a series of large and super large porphyry deposits. There arevarious mineralization styles including porphyry copper, porphyry molybdenum,porphyry gold, porphyry copper-molybdenum (gold) and epithermal gold/silver. These deposits formed in a variety of tectonic settings including subduction, collision, and post-collision extension.

Funded by a series of grants issued by theNatural Science Foundation of China (e.g., such as major project), 973 Project, National key research and development program), many researchers have been given the opportunity to undertake research into the porphyry deposit systems inthe Central Asian, Tethys and western Pacific orogenic belts. These wideranging results have contributed to our understanding of the geodynamicsetting, crust-mantle interactions, magma-fluid evolution, source ofore-forming elements and the metal enrichment mechanisms for deposits in thisregion.
