Tongshugou gold-copper mining area is located in the North Asia with Xiong' ershan many metal metallogenic belt a-bout gold, silver, copper, lead, zinc. And that is in the West-middle section of Xiong' ershan metamorphic core complex's structure of the southern of North China ancient land. The ore belts strictly by structural control, appear differentiation in the space. Approximately the east-west gold ore belt occurs in the andesite of the Mesoproterozoic Xiong' er Group Xushan formation and the diorite of the Jinning period. But the north-east gold ore belt occurs in the amphibole-plagioclase gneiss of the Archeozoic Taihua Group Shibangou formation. Both them all belong to tectonic altered rock type. Combined with the analyzed datas about the geophysics and the rock ore appraisal, the authors have the conclusion that there is good metallogenic tectonic and mineralization information. The north-east and the nearly east-west tectonic altered belts who are rich in the primary and secondary sulfide and the stable occurrence, are with the great gold-copper prospecting potential.%桐树沟金铜矿区位于熊耳山金、银、铜、铅、锌多金属成矿带之北亚带上,属华北古陆南缘熊耳山变质核杂岩构造的西段.矿带严格受构造控制,在空间上出现分异,即近东西向的金矿带赋存在中元古界熊耳群许山组安山岩及晋宁期闪长岩中,而北东向的铜矿带赋存在太古宇太华群石板沟组角闪斜长片麻岩中,两者矿床类型均属于构造蚀变岩型.结合地球物理及岩矿鉴定分析数据,可得出结论:该区具有优良的成矿构造及矿化信息.其富含原生及次生硫化物且产状稳定的北东向、近东西向构造蚀变带,具有很大寻找金铜矿的潜力.
