| 摘 要： | 哈茨谱山北矿区位于青海省都兰县东部,其大地构造位置处于秦祁昆晚加里东造山系、东昆北造山带、祁漫塔格-都兰造山亚带的东段,区内构造活动和岩浆活动强烈。铜铅银金多金属矿矿床赋存于晚志留世英云闪长岩中,矿体产出严格受断裂构造控制,并受火山热液的叠加。矿体形态呈脉状、透镜状。通过对矿区内地层、控矿构造、侵入岩、矿体特征和矿石质量的分析论述,认为该矿床为中—低温火山期后热液型铜铅多金属矿床。

| Abstract: | Hacipu Mountain North Area is located in east of Dulan county in Qinghai province. Its geotectonic location is in east part of Qinqikun late Caledonian orogenic belt, north part of Kunlun orogenic belt, and east part of Qimantage-Dulan sub-orogenic belt. Tectonic and magmatic activities are strong in this area. Cu-Pb-Ag-Au polymetallic deposit occurred in late Silurian tonalite. Ore production was strictly controlled by fractural structures, and superimposed by the volcanic hydrothermal. Ore bodies are vein and lenticular type. Through analysis and study on mainland layers, ore-controlling structures, intrusive rocks, geological characteristics and ore quality, it is regarded that this deposit is a medium-low temperature after the volcanic hydrothermal type copper lead polymetallic deposit. |
