| 摘 要： | 原生晕分析是研究矿床深部矿化远景的有效手段.由于所取丰宁银矿原生晕样品中包含氧化样品,致使分带序列研究中各种方法计算结果差别很大.在对矿床成矿及伴生元素进行多元统计分析基础上,重点对原生晕数据进行了R型因子分析,结果表明R型因子分析对处理包含氧化样品的混杂原生晕数据非常有效,并对同类型矿床的原生晕处理具有参考价值.

| Abstract: | Primary halo is very effective to detect the deep mineralization of ore deposits.As primary halo samples collecting from Fengning silver deposit contain oxidized samples, these exists large difference among the results of different zoning sequence calculations. Based on multivariant statistical analysis of metallogenic and associated elements in the Fengning silver deposit, it is indicated that R-factor analysis is very effective for handling mixed geochemical data, and can provide references to deal with primary halo in the same kinds of ore deposits. |
