摘　　要：雅沙图地区是青海省内萤石矿富集区,开展其矿床特征及找矿前景分析具有重要的现实意义。文章结合雅沙图地区的地质条件及构造背景,分析了矿区矿床地质特征及控矿因素,并进一步总结了找矿标志及找矿前景。分析成果表明:研究区内断裂构造发育,主要存在着北西—南东向、北北向两组断裂构造,萤石矿体主要产于断裂或构造裂隙带中,与断裂构造具密切关系,其品位范围主要间于为14.98%~53.26%。同时,雅沙图地区的找矿标志较为明显,具有良好的成矿地质条件和构造背景,各类条件及特征均显示了雅沙图地区具有较大萤石矿找矿潜力。The Yashatu area is an enriched area of fluorite deposits in Qinghai province,and conducting analysis on its deposit characteristics and prospecting prospects has important practical significance.The article combines the geological conditions and structural background of the Yashatu area to analyze the geological characteristics and controlling factors of the mineral deposits in the mining area,and further summarizes the prospecting indicators and prospects.The analysis results indicate that there are two sets of fault structures developed in the study area,mainly northwest southeast and north north.The fluorite ore body is mainly produced in the fault or structural fracture zone,which is closely related to the fault structures.Its grade range is mainly between 14.98%and 53.26%.At the same time,the prospecting indicators in the Yashatu area are relatively significant,with a good geological and structural background for mineralization.Various conditions and characteristics indicate that the Yashatu area has great potential for fluorite ore prospecting.
