| 摘 要： | 相山铀矿田是我国目前规模最大的火山岩型热液铀矿田,其发育碱交代型铀矿化和酸交代型铀矿化两种矿床类型。笔者通过对该矿田主要酸交代型铀矿床的物质组分研究,发现其矿石中富含Th、Mo、HREE、Y等多种有用组分,且含量普遍可达综合利用品位;有用组分主要以独立矿物、类质同像形式存在,主要赋存于铀矿体的矿化中心带富矿石中,与铀为同空间富集。因此认为,相山铀矿田酸交代型矿床的矿石中,Th、Mo、HREE、Y与铀密切相关,矿物具有共生关系;应重视Th、Mo、HREE、Y等有用组分的综合利用评价。

| Abstract: | Xiangshan uranium ore-field is the largest volcanic hydrothermal uranium ore-field in China which produce two types uranium ore of alkaline metasomatism and acidic metasomatism.Comprehensive study found that the acidic mineralized ores contain Th,Mo,HREE,Y and other profitable elements and their content generally reached the comprehensive utilization grade;and Th,Mo,HREE and Y are closely related to U and the minerals and mainly exist in the form of independent mine rals and isomorphism.Because the profitable elements mainly was found occurring as symbiosis in the high-grade uranium ores,therefore attention should be paid to the comprehensive evaluation of the profitable elements such as Th,Mo,HREE and Y in the acidic metasomatism uranium ores in Xiangshan ore-field. |

| Keywords: | acidic mineralization profitable symbiosis elements comprehensive utilization Xiangshan uranium ore-field |
