摘　　要：青石钨矿地处南岭东段罗霄—诸广隆起九龙脑岩体南东内侧,含钨石英脉受近东西向裂隙系统控制,属内接触带石英脉型钨矿床,钨矿体由石英脉及两侧云英岩组成,矿石矿物主要为黑钨矿、白钨矿。采用了地质勘查及岩矿鉴定,结合多元素分析、物相分析、矿物组成测定、钨元素嵌布粒度测定等手段,对比了类似矿床矿石特征,论述了钨的赋存状态及其分布规律,所形成的青石钨矿找矿新成果,为九龙脑岩体及周边寻找内接触带型钨矿有借鉴意义。Qingshi tungsten deposit is located in the southeast inner side of the Jiulongnao rock body in the Luoxiao-Zhuguang uplift in the eastern part of the Nanling Mountains.The tungsten-bearing quartz vein is controlled by the nearly east-west fracture system,and belongs to the quartz vein type tungsten deposit in the inner contact zone.The tungsten ore body is composed of quartz vein and two sides of greisenite.The ore minerals are mainly wolframite and scheelite.By means of geological exploration and rock and ore identification,combined with multi-element analysis,phase analysis,mineral composition determination,tungsten element embedded particle size determination and other means,the ore characteristics of similar deposits are compared,the occurrence state and distribution law of tungsten are discussed,and a new understanding of the new progress in prospecting for the Qingshi tungsten deposit is formed,which has reference significance for the Jiulongnao rock body and its surrounding areas to find the internal contact zone type tungsten deposit.
