对比研究了夏塞银铅锌矿床不同矿脉矿石、与成矿有关的岩体及围岩的稀土元素地球化学特征,借以示踪成矿物质来源。研究表明,床不同类型银铅锌矿石中的稀土元素配分曲线较为相似,成矿物质具有同源性,银铅锌矿石的稀土元素球粒陨石配分模式呈右倾斜型式,具有显著的δEu负异常,与矿区西南侧的绒衣错黑云母二长花岗岩体基本一致,表明两者具有一定的成因联系。 The geochemical characteristics of rare earth elements in different ore veins of Xiaxian silver-zinc-zinc deposit, rock mass and surrounding rock associated with ore-forming are comparatively studied to trace the origin of ore-forming materials. The results show that the distribution patterns of REE in different types of silver-lead-zinc ores are similar, and the metallogenic materials have homology. The REE chondrite melange patterns of silver-lead-zinc ores show a right-inclined pattern with significant δEu negative anomalies , Which is basically the same as the Erlian fault biotite monzogranite body on the southwestern side of the mining area, indicating that the two have a certain genetic relationship.
