摘　　要：萤石主要应用于钢铁和化工行业,市场对萤石的需求一直在持续增长,萤石已经成为中国战略性矿产。随着低品位重晶石萤石共生矿综合利用关键技术取得重要突破,在武陵山地区(渝黔湘交汇区)重晶石萤石共生矿床逐渐被重视及利用。通过野外地质工作,以务川双河重晶石-萤石矿矿床地质特征为研究对象,认为务川双河重晶石-萤石矿床受地层、构造2个因素共同控制成矿,主要赋矿层位为奥陶系下统红花园组,提出重晶石-萤石矿体受奥陶系下统红花园组及北西向构造控制的找矿方向,该认识有助于贵州武陵山地区开展进一步找矿工作,并积极助力该区矿业开发、服务脱贫攻坚工作。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.
