Abstract:The paper focuses on geological and geochemical evidence of thermal brine genesis of Pb-Zn de-posits in Wuqia district, Xinjiang. The results suggest that the known Pb-Zn deposits, such as Wulagen, are thermal brine genesis, which is supported by the features of tectonic setting, magma and regional metamor-phism, and the characteristics of trace element distribution in strata and redistribution in the ore-forming process, the REE patterns and their main parameters of main type ores, the composition features and the source indicators of Pb, S isotopes. Ore-forming conditions of superlarge Pb-Zn deposits studies show that there exists tectonic and sources setting of Jinding-type superlarge Pb-Zn deposits in this area. Five Pb-Zn ore belts and central uplift belts discovered lately have not only confirmed that the genesis of Wulagen Pb-Zn deposits is thermal genesis, but also further proved that there exists tectonic and source setting of Jinding-type superlarge Pb-Zn deposit in the study area. Mineral depositmodelwas described and prospecting potentiality of superlarge Pb-Zn deposit and their significance were discussed.
