| 摘 要： | 通过对相山铀矿田微量元素进行判别分析、Q聚类分析和R型分析,表明围岩与矿石之间的关系较远,U、Th、Pb、Li、Rb、Sr、Ba、Zr、Y、Mo、Zn、P、Ti可将岩石划分为围岩、蚀变岩石和矿石三类。矿物学特征研究表明,铀矿化分为早期的钛铀矿-磷灰石矿化与晚期的铀石-硫化物-方解石矿化两期矿化。结合以上两个方面,相山铀矿田的成矿物质来源与围岩无直接关系,成矿的热液系统分为高温热液系统和低温热液系统。

| Abstract: | Discriminant and cluste methods were applied to analyze the trace elements of the Xiangshan uranium orefiled.The results showed that the surrounding rock and the ore are not closely related.The rock can be classified into three categories,wall rock,altered rock and ore,according to the data of U,Th,Pb,Li,Rb,Sr,Ba,Zr,Y,Mo,Zn,P,Ti,and the uranium mineralization can be divided into early uranium-apatite mineralization and late uranium-sulfide-calcite mineralization according to the mineralogical characteristic... |
