相山铀矿田邹家山矿床成矿流体特征

Mineralization Fluid Features of Zoujiashan Uranium Deposit in Xiangshan Ore-field,Jiangxi

通过流体包裹体的岩相学研究、显微测温和激光拉曼探针测试,探讨了邹家山铀矿床成矿流体特征、演化及矿质沉淀方式。研究结果表明,该矿床的成矿流体为中低温热液,碳氢化合物对铀的富集具有不可忽视的作用,流体持续的沸腾作用是矿质沉淀的主要因素。

Based on the petrographic analysis,temperature measurement,laser Raman study of fluid inclusion,this paper discussed the features, evolution and precipitation forms of mineralization fluids. According to the research,the fluid belong to middle low temperature and uranium was transported by carbon dioxide and organic matter,fluid boiling is suggested to be the main mechanism for metal precipi-tations in this deposit.
