Abstract: Abstract: The Zhuxi tungsten?copper deposit, discovered in northern Jiangxi in recent years, is a potential superlarge skarn deposit. Based on the geological setting and geological features of the ore deposit, the authors analyzed the rare earth and trace elements of the magmatite and skarn ores in the drill holes. Combined with the ore-bearing properties of the granitoid, the mineralization zoning, and the pre-existing geochronological data, this paper preliminarily discusses the geochemical characteristics of the granite and their constraints on mineralization of the Zhuxi tungsten-copper deposit. It is suggested that the granite is closely related to metallogenesis, and the mineralization of Zhuxi tungsten?copper polymetallic deposit is controlled by the crustal remelting granite which may have resulted from the large?scale lithospheric extension of southern China during the Mesozoic.
