Abstract: Fluorite is mainly used in the steel and chemical industries. The market demand for fluorite has been growing, and fluorite has become a strategic mineral in China. With the exhaustion of fluorite resources in the main producing areas (Zhejiang, Hunan, etc.), the barite fluorite deposit has been paid more attention and utilized in Wuling Mountain area (the adjacent place of Chongqing, Guizhou and Hunan). Through field geological work, the geological characteristics of shuanghe Barite-fluorite deposit in Wuchuan were studied, it is considered that the Shuanghe Barite-fluorite deposit in Wuchuan is controlled by the lower Ordovician Honghuayuan formation and the NW trending development of tensile fractures, the ore-bearing horizon is the Lower Ordovician Honghuayuan group, It is proposed that the ore-prospecting direction of the barite-fluorite ore body is controlled by the Lower Ordovician Honghuayuan Formation and the NW direction structure, It is helpful for further prospecting work in Wuling Mountain area of Guizhou province, it will actively support the development of mining industry in the region and provide services for poverty alleviation.
