The East China Mesozoic metallogenic province hosts the world's largest resources of tungsten, tin, molybdenum, antimony and bismuth, with additional important gold, silver, mercury, lead, zinc, copper, uranium and iron deposits. These deposits form several giant metallogenic belts, including South China, Middle-Lower Yangtze River Valley, East Qinling-Dabie, eastern North China Craton and North-east China. Available data demonstrate that these metallogeneic belts are the products of episodic magmatic and related hydrothermal events between ~240 and ~80 Ma. Each magmatic-hydrothermal episode has produced distinct deposit assemblages that can be readily linked to the Mesozoic geodynamic evolution of East China, involving continental collision between the North China Craton and South China Block at 220-200 Ma, oblique subduction of the Izanagi plate under the Eurasian continent at ca 170-135 Ma and post-subduction extension and lithospheric delamination at 130-80 Ma. Metallogeny in north-eastern China is more complicated due to prolonged tectonic evolution related to southward subduction of the Mongolian-Okhotsk plate and westward oblique subduction of the Izanagi plate, and subsequent continental collision and post-collisional processes.CITATION:Mao, J W, Xie, G Q and Cheng, Y B, 2015.
