The Taoxikeng tungsten deposit, located in southern Jiangxi Province, is a typical greisen-type wolframite deposit. This paper focuses on REE geochemistry of the Sinian sand-slates, ore-forming granites, mineralization greisen veins and the quartz veins in this deposit. Based on analyses of petrochemical compositions, REE distribution patterns and characteristic values （including EREE-LREE/HREE and ~Eu-LREE /HREE）, comparisons with REE compositions of modern marine and terrestrial sediments, we infer that protoliths of the Sinian sand-slates are shallow marine terrlgenous sedimentary rocks, and the genesis of ore-forming granites is related to melting of the continental crust. The mineralization greisen veins, quartz veins and oreforming materials are all the products of postmagmatism hydrothermal fluid.
