| 摘 要： | 笔者以地球化学原生晕理论为指导,对孟公界铀矿床1号矿体按不同标高进行了采样分析,并对分析数据进行多重数理统计;应用叠加原生晕模型对该矿床的指示性元素的轴向分带规律进行研究,建立了指示性元素自上而下的理想分带序列:Hg-As-Sb-Mo-Ag-Cu-U-W-Cd-Bi-Pb-Sr;结合不同成矿阶段的蚀变矿物组合,构建了孟公界地区热液型铀矿的矿物-蚀变-元素组合原生叠加晕模型。以此为基础,建立了原生晕预测技术指标,用于指导找矿工作。

| Abstract: | Guided by the theory of original geochemical halo,samples at different elevation of orebody No.1 in Menggongjie uranium deposit was collected and chemically analyzed.Statistics of the chemical data was preformed to study the vertical zonation pattern of indicating elements with superimposition model of original halos.An ideal vertical elementary zoning sequence of uranium body was established as Hg-As-Sb-Mo-Ag-Cu-U-W-Cd-Bi-Pb-Sr from up to bottom.The combination prospecting model of min-eral-alteration-original element halo was set up with the alteration mineral of different ore-forming stage, which was used to constitute the geochemical forecasting technology of original halos so as to instruct the uranium exploration. |
