Abstract

Abstract

The Xushan tungsten-copper deposit is located in the central part of Jiangxi Province. It is a trinity deposit comprising three types of ore-bodies, i.e. quartz vein type, skarn type, and granite type. Rb-Sr micro-isochron method is first applied to determining the ore-forming age by using single grain of muscovite growing at the edge of the wolframite-quartz vein type tungsten ore. Result shows that the mineralization age is 147.1±3.4 Ma, with MSWD=0.71, and the I_Sr value is 0.849±0.026. This ore-forming age is similar to those of quartz-wolframite-vein tungsten deposits in southern Jiangxi, but is much later than the ages of copper deposits in northeastern Jiangxi and slightly earlier than the ages of copper deposits in northwestern Jiangxi. The very high I_Sr value may suggest that the ore-related granite was a melting product of highly evolved and highly saturated crust material, and the ore-forming fluids have extracted the strontium of extremely high ⁸⁷Sr/⁸⁶Sr ratios from the granite through water-rock interaction. It also suggests that there was almost no contribution of mantle material during the formation of either ore-related granite or tungsten mineralization.
