西藏狮泉河霞尼夺布铅锌矿点地质与地化特征分析

Geological and Geochemical Characteristics of the XiaNiDuoBu Lead-Zinc Mine Site in Shiquan River, Tibet

狮泉河霞尼夺布铅锌矿点位于冈底斯—念青唐古拉成矿带。该区域岩浆活动较为频繁,发育大量岩体,同时发育较多的断裂构造。铅锌等元素在热液活动下不断聚集最终在断裂构造和接触带边缘聚集成矿。对其地质和土壤地球化学特征分析表明,霞尼夺布铅锌矿点属于热液型,工区同时有利于铜金等元素的富集成矿。对于今后铜金等其他矿点的发现具有指导意义。

The XiaNiDuoBu Lead-Zinc Mine Site in Shiquan River is located in Gangdise-Nianqing Tanggula metallogenic belt.The magmatic activity in this area is relatively frequent,a large number of rock masses are developed,and more fracture structures are developed at the same time.Elements such as lead and zinc continue to accumulate under the action of hydrothermal fluids,eventually accumulating ore at the edges of fault structures and contact zones.The analysis of its geology and soil geochemistry shows that the XiaNiDuoBu lead-zinc deposit is a hydrothermal deposit,and the work area is also conducive to the enrichment of copper and gold and other elements.It is instructive for the discovery of other copper ore deposits in the future.
