摘　　要：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。REE geochemistry was studied by comparing different ores from various veins and magmatic bodies related with mineralization and country rock of Xiasai silver-lead-zinc deposit to trace metallogenic matter origin.Silver-lead-zinc ore and Rongyicuo biotite monzonite granites on the southwest side of Xiasai silver-lead-zinc mine had almost the same chondrite-normalized REE patterns,which was characterized by remarkable δEu negative anomaly.The results indicated that the metallogenic matters for different type ores from the same origin were mainly related to Rongyicuo biotite monzonite granites in genesis.
