The distribution of metal minerals in the adjacent areas of Zhejiang, Jiangxi and Anhui shows the characteristics of Jindong Jindong tungsten and tin. Sixteen major linear fault zones and JiuLing and Huaiyu terranes are overlapped to form a first-level ore-control fracture network in the region. In the same period, the distribution of rock mass around the network nodes of different types of metal mineralization constitutes ore-scale porphyry The ore system, both of which determine and control the spatial distribution of metal deposits including copper and gold deposits in the regional scope and orefield area, respectively. The strong tectonomagmatic activity of Yanshanian period accompanied by the explosive metallogenic process. Copper and gold mineralization are mainly related to the type I intermediate acidic granitoids in the early Yanshanian. The ore-forming elements are partly derived from different strata in the shallow part, especially the Middle Proterozoic and Middle Proterozoic ore-bearing rocks, and from the lower crust to the mantle. The combination of ore-forming geological conditions and prospecting signs in the Dexing copper-gold area is unique in the area, but there are still potential for prospecting for medium- and large-sized copper and gold deposits in the surrounding areas. The four preferred general survey areas are expected to develop into Copper, gold exploration base. It is possible to get a multiplier effect by using the stratigraphic positioning of the metallogenic fault network and ore prospecting models of copper-rich and gold-porphyry ore-bearing systems in the area for copper and gold prediction.
