摘　　要：矿区内钨矿化位于褶皱构造两翼断裂构造,矿体走向为N-E。成矿体多分布在深、大断裂旁侧次级断裂内,区域上岩浆活动强烈,岩性多为酸性-中酸性、少量中性及基性岩脉。不同成因类型的花岗岩具成矿专属性,在后加里东隆起区以石英脉型钨矿床为主,由于变质作用的原因,矿区域内岩石常见变质和蚀变现象,各种蚀变常互相重叠。通过地质测量、民窿清理等工作总结了区内的地质特征和找矿标志,为下一步找矿提供方向,为后续项目提供有力的指导和引领作用。The tungsten mineralization in the mining area is located in the two wings of the fold structure and the fault structure,with the ore body trending N-E.Orebodies are mostly distributed in secondary faults on the side of deep and large faults,with strong magmatic activity in the region.The lithology is mostly acidic to moderately acidic,with a small amount of neutral and basic veins.Granites of different genetic types have mineralization specificity,with quartz vein type tungsten deposits being the main type in the post Caledonian uplift area.Due to metamorphism,rocks in the mining area commonly undergo metamorphism and alteration,and various alterations often overlap with each other.The geological characteristics and prospecting indicators in the area were summarized through geological surveys,clearing of civil tunnels,and other work,providing direction for the next step of prospecting and providing strong guidance and guidance for subsequent projects.
