| 摘 要： | 该文研究了桂东北地区三种不同类型铀矿床中沥青铀矿及其围岩的稀土元素分布模式。三种类型铀矿床的沥青铀矿的稀土元素分布模式十分相似,这反映出它们形成的物理化学条件可能近似。沥青铀矿与含矿围岩的稀土元素分布模式类同,说明成矿物质主要由围岩本身提供;有可能根据沥青铀矿的稀土元素分布模式来追溯铀源。

| Abstract: | The distribution patterns of rare earth elements of pitchblende and surrounding rocks in three types of uranium deposits have been studied. The distribution patterns of rare earth elements of pitchblende in three types of uranium deposits are very identical, reflecting that the pitchblende was formed under the same physicochemical conditions. The distribution patterns of rare earth elements of pitchblende and surrounding rocks are similar. It shows that the uranium for the three types of uranium deposits was derived possibly from surrounding rocks themselves. Consequenrly, it is possible to trace uranium source according to the distribution patterns of rare earth elements of pitchblende. |
