| 摘 要： | 西藏那曲县尤卡朗铅银矿床位于当雄-嘉黎铅银多金属成矿带中部，含矿地层为中-上休罗统拉贡塘组，含矿岩性为滨浅海相复理石建造。矿体受NE向断裂控制，与地层和构造关系密切。成矿机制为深部基性—超基性岩浆热液在运移过程中革取围岩中的成矿物质，在NE向断裂构造带富集成矿。

| Abstract: | The Youkalang Pb-Ag deposit of Naqu County in Tibet located in the central part of Dangxiong- Jiali Pb-Ag polymetallic mineralization zone with the ore-bearing strata being Lagongtang Formation of middle-upper Jurassic series, while the ore-bearing lithology being littoral neritic facies flysh. The orebodies are controlled by NE trending fault and close related to strata and structure. The ore-forming process is that the ore-forming matters were extracted when deep basic-ultrabasic magmatic hydrothermal fluids moved, then deposited and enriched in NE trending fault and structural zone. |
