摘要
本文研究了8412铀矿床中沥青铀矿及其围岩的稀土元素分布模式和Sr,Nd同位素组成。反映它与大陆裂谷活动有关。明显不同于华南一些铀矿床的成矿物质主要由围岩提供的特征。可以根据沥青铀矿的稀土元素模式来追溯铀源.
The distribution patterns of rare earth elements and Sr, Nd isotopic compositions of pitchblende and country rocks in uranium deposit No. 8412 have been studied. The data show that the pitchblende was formed under the conditions of similar continental rift activity. It is obviously different from the uranium deposits in South China which were possibly derived from country rocks themselves. Consequently, it is possible to trace the uranium source according to the distribution patterns of rare earth elements of pitchblende.
