摘　　要：龙潭沟金矿区位于嵩县南部熊耳山断隆与潭头—大章断陷盆地的结合部位,区内岩浆活动强烈,断裂构造较为发育,具备良好的成矿地质条件。对龙潭沟金矿地质特征及矿床成因分析表明,区内金矿严格受断裂构造带控制,矿区东北部的燕山期五丈山斑状二长花岗岩体与本区金矿化关系密切。矿石类型主要为细脉—浸染状黄铁矿金矿石和碎裂—角砾状金矿石。矿床成因类型属受岩浆热液作用形成的构造蚀变岩型金矿床。找矿标志主要为构造、蚀变矿化、岩浆岩和民采硐。The Longtangou gold mining area is located at the junction of the Xiong'ershan fault uplift and the Tantou-Dazhang fault basin in the south of Song County.The area has strong magmatic activity,rel⁃atively developed fault structures,and has good metallogenic geological conditions.The analysis of the geo⁃logical characteristics and genesis of the Longtangou gold deposit shows that the gold deposits in the area are strictly controlled by faulted structural belts.The YanshanianWuzhangshan porphyritic monzonitic gran⁃ite body in the northeastern part of the mining area is closely related to the gold mineralization in this area.The main types of ore are veinlet-disseminated pyrite gold ore and fragmented-breccia gold ore.The genetic type of the deposit is a tectonic alteration rock type gold deposit formed by the action of magmatic hydro⁃thermal fluid.The prospecting signs are mainly structure,alteration mineralization,magmatic rock and civil mining cave.
