| 摘 要： | 分析了粤西廉江庞西垌银矿床不同地质岩石稀土元素地球化学特征，对矿床围岩花岗岩的成因以及矿床成矿物质来源进行了讨论，认为英桥花岗岩体为壳幔混合源同熔花岗岩。银矿床中矿化蚀变岩继承了原岩的稀土特征，热液成因石英脉的稀土元素特征与混合岩基本一致，反映成矿物质主要来源于混合岩。

| Abstract: | Based on the analysis of REE geochemical characteristics of different geologic rocks in Pangxidong silver deposit, the genesis of granitic wallrocks and the source of mineralised material are discussed. It indicates that Yingqiao granite belongs to syntectic granite of mixed crust mantle source. Mineralized altered rocks in the silver deposit inherit REE characteristics of source rocks and REE characteristics of hydrothermal quartz vein are basically consistent with migmatite, which shows that mineralised material is mainly from migmatite. |
