| 摘 要： | 江西相山铀矿田沙洲铀矿床的矿体严格受断裂控制,围岩蚀变分带非常明显。对沙洲铀矿床围岩蚀变的地球化学特征进行的研究表明,沙洲矿床从矿石到围岩的化学成分具有明显的变化,这些化学成分的变化与蚀变过程中物质的带入带出是密切相关的。通过对全部样品进行R型聚类分析,确定矿床成矿元素组合为U、W、HREE、Th、Zn、Zr、Mo、Pb,这些元素可作为铀成矿预测标志。研究成果在一定程度上充实和丰富了沙洲铀矿床的成因认识。 |

| Abstract: | The ore body of Shazhou deposit in Jiangxi Province is strictly controlled by faults and its wall rock alteration zoning characteristics is very apparent. This paper introduces the geochemical characteristics of the wall rock alteration. The results of whole-rock analysis of Shazhou deposit show that the chemical composition of the ore body is very different from the surrounding rock and the differences are relevant with the migration of chemical elements in the course of alteration. The combinations of metallogenetic elements are U, W, HREE, Th, Zn, Zr, Mo, Pb based on R-mode cluster analysis of all the rock samples and these elements can serve as the criteria for U ore prospecting in the region. |
| Keywords: | Shazhou deposit wall rock alteration correlation of elements geochemical characteristics |
