In the early period of the late Proterozoic Era (1100 m.y. +/-) an aulacogen mobile belt was formed in the southeast of China. It extends about 1000 km crossing the Yantze Platform and Jiangnan Foldbelt in NNE-NE direction and adjoins the south China geosyncline basement. This belt shows some features of geology and mineralization similar to the Adelaide geosyncline and the Zambia-Zaire Copper-uranium belt. Within the belt, there are about 9000 to 12,000 m polystratotype strata and continuous sediments of the Late Proterozoic Erathem, including alkaline and meta-alkaline volcanic products of 4 epochs of mainly marine facies. A great number of ore-forming elements, such as Cu, U, Pb, Zn, Au, Ag, Fe, Co, Ni, Mn, P, and W, Sn, TR etc., were deposited and enriched in the whole volcano-sedimentary sequency at various times and in various places. A few of them have become syngenetic deposits, but most of them have been transformed into large-scale ore deposits or mineralization fields or areas of copper and gold, lead-zinc and silver, uranium, tungsten, tin, and other metals.
