摘　　要：梧桐沟钨矿区位于塔里木板块北缘,是东天山成矿带内继忠宝钨矿之后发现的又一钨矿床。两处钨矿床的发现为该区域矿带内寻找钨矿奠定了良好基础。通过系统研究区域成矿地质背景、矿床特征、地球物理特征、地球化学特征等找矿信息,在地质找矿理论指导下,对梧桐沟钨矿矿床综合找矿信息进行提取,初步建立以“钙碱性高钾型花岗岩+碎屑岩-碳酸盐岩建造+W,Sn,Bi,Cu综合异常+中高重力异常+云英岩化-矽卡岩化-硅化-孔雀石化”为核心的矿床综合信息找矿模型,对东天山地区钨矿找矿和勘查具有指导意义。Wutonggou Tungsten Mine is located on the northern edge of the Tarim Block.It is another tungsten deposit discovered in the East Tianshan metallogenic belt after the Zhongbao Tungsten Mine.The discovery of these two tungsten deposits has laid a good foundation for the search for tungsten deposits in the regional mineral belt.Based on the systematic study of regional metallogenic geological background,deposit characteristics,geophysical characteristics,geochemical characteristics and other prospecting information,and under the guidance of geological prospecting theory,this paper extracts comprehensive prospecting information for the Wutonggou tungsten deposit and preliminarily A model based on“calc-alkaline high-potassium granite+clastic rock-carbonate formation+comprehensive anomalies of W,Sn,Bi,Cu+medium-high gravity anomalies+greitzization-skarnization-silicification-malachitization”was established.The comprehensive information prospecting model of mineral deposits as the core has guiding significance for tungsten ore prospecting and exploration in the East Tianshan area.
