摘　　要：角西石英脉型黑钨矿床系班公湖—怒江成矿带西段发现的首个独立黑钨矿床。文章通过对其矿体产出形式、矿化特征、蚀变类型等方面的研究,认为矿床成因类型属与岩浆热液有关的石英脉型黑钨矿。基于矿床现有的激电剖面测量和土壤地球化学剖面结果并结合矿床成因类型分析,笔者认为矿区尚具有一定找矿潜力,尤其云英岩型钨矿体应为下一步找矿工作部署的重点。角西石英脉型黑钨矿的发现将会丰富班公湖—怒江成矿带矿床成矿系列,完善区域成矿规律,拓展区域找矿方向,具有重要的区域成矿学与找矿意义,值得进一步研究。The Jiaoxi quartz-vein type wolframite ore deposit is the first single wolframite ore deposit found in the western part of the Bangong Co–Nujiang metallogenic belt. In this paper, the occurrence characteristics of wolframite orebodies, features of wolframite mineralization, and alteration types of wall rocks were analyzed. Based on the results obtained, the authors hold that the Jiaoxi wolframite deposit should be classified as quartz-vein wolframite ore deposit related to magmatic hydrothermal activity. Based on results of soil geochemical survey and induced polarization measurement combined with the confirmation of genetic type of the Jiaoxi deposit, it is believed that this mining area has some potential in search for quartz-vein wolframite orebodies, especially in the prospecting for the greisen-type wolframite orebodies. The discovery of the Jiaoxi single quartz-vein wolframite ore deposit will enrich the minerogenetic series of mineral deposits in the Bangong Co–Nujiang metallogenci belt. In addition, its discovery has a great significance for improving regional metallogenic regularity and mineral prospecting. Thus, further researches on the Jiaoxi wolframite ore deposit are necessary in the near future.
