This paper mainly introduces geological background and mineralization characteristics of the Taoxikeng large-scale tungsten deposit in Chongyi, Jiangxi Province, and particularly describes in detail the shape, distribution, mineral composition and chemical composition of the Taoxikeng granite body and summarizes the latest researches related to isotopic ages and geochemical data in order to discuss the mineralization of the granite body which is as the parent rock for mineralization. In the end, the overall shape of the ore-forming body is prognosticated and the favorable areas for ore-prospecting in the further work are analyzed.
