| 摘 要： | 居隆庵矿床是相山矿田中一个大型的铀-钍混合矿床。通过系统的镜下显微特征研究和电子探针分析,查明了主要钍矿物和含钍矿物的种类,分析了钍的赋存状态和蚀变特征。钍的赋存状态有独立钍矿物、类质同象替换铀矿物和类质同象存在于副矿物中。相关的矿化蚀变有碳酸盐化、钠长石化、绢云母化、黄铁矿化、绿泥石化、水云母化和萤石化。本文还总结了钍(铀)矿物的赋存位置。

| Abstract: | Julongan deposit is a large uranium-thorium deposit in the Xiangshan ore field.This study investigated the thorium and thorium-bearing minerals and summarized occurrences and mineral alterations of thorium using microscope and electron microprobe techniques.The results indicated that thorium has several occurrences in the deposit,including independent thorium minerals,isomorphic form existing in uranium minerals,and micro-isomophic form lying in accessory minerals,and that mineralized alterations related wi... |
