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

The Central Asian, Tethyan and Pacific Metallogenic Domains, located in the north orogenic belt of China and in nearby countries, host a series of large and super large porphyry deposits. There are various 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 the Natural 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 in the Central Asian, Tethys and western Pacific orogenic belts. These wide ranging results have contributed to our understanding of the geodynamic setting, crust-mantle interactions, magma-fluid evolution, source of ore-forming elements and the metal enrichment mechanisms for deposits in this region.

The Key Laboratory of Mineral Resources, Institute of Geology and Geophysics, Chinese Academy of Sciences (Beijing) will be sponsoring a two-day symposium (September 8th-9th, 2018, Beijing) devoted to promoting the following fields: (1) Clarifying the relationship between different types of porphyry deposits and dynamic process; (2) Investigating the influence of porphyry magmatic and fluid systems on metal enrichment, migration and precipitation; (3) Revealing the connection between deep crust-mantle events and large-scale porphyritic mineralization; (4) Deciphering the factors governing metal provinces, grade and scale, and (5) Capturing the core scientific issues of large-scale mineralization. This symposium will build a platform to facilitate communication of achievements in the field of porphyry deposit system evolution in the three different metallogenic domains and will enhance exploration success in the region. We are warmly anticipating your attendance and participation in Beijing.
