摘　　要：陕西省太白县北沟金矿位于凤太矿集区东南部,相邻地区铅、锌、金多金属矿产资源丰富。矿点内圈出7条金矿体,地表呈透镜状、囊状产出,深部矿化向Au、Pb、Zn多金属矿组合转变,其成因应为含金热液流体上侵过程中在北西向区域主断裂与北东向节理、裂隙交汇地段富集成矿。矿点具备中低温热液金矿床成矿的构造、岩浆条件,深部具有较大的找矿潜力,有望成为中型金矿床的远景规模。Beigou gold mine in Taibai County,Shaanxi Province is located in the southeast of Fengtai Ore Concentration Area.The adjacent area is rich in lead,zinc and gold polymetallic mineral resources.Seven gold ore bodies are circled in the mine site.The surface is lenticular and sac-like.The deep mineralization transforms to the combination of Au,Pb,and Zn polymetallic minerals.The cause is that the gold-bearing hydrothermal fluids the area where the main fault in the north-west direction intersects with the north-east direction joints and fissures is rich in ore.This ore site has the structure and magmatic conditions for the formation of medium and low temperature hydrothermal gold deposits.The deep part has a large prospecting potential and is expected to become a medium-sized gold deposit.
