STUDY ON THE CHEMICAL SPECIES OF PLATINUM GROUP ELEMENTS IN GEOLOGICAL SAMPLES BY MOLECULAR ACTIVATION ANALYSIS

  • 摘要: 用化学逐级溶解、镍锍火试金预富集及中子活化分析法研究了中国东部大陆地幔橄榄岩捕掳体中铂族元素的化学种态。分析结果表明 ,6个物相中单个铂族元素的质量分数加和与铂族元素总量分析结果基本相符 ;硫化物相中铂族元素分布特征的研究 ,进一步说明了硫化物的熔出是部分熔融过程中地幔橄榄岩铂族元素分异的重要机制之一。
    Abstract: The chemical species of platinum group elements in some upper mantle derived xenoliths from Eastern China are studied by molecular activation analysis,in which the chemical stepwise dissolution,nickel fire assay preconcentration and neutron activation analysis are jointly applied. The weighted sums of platinum group elements in 6 phases are in agreement with their total contents.The distribution patterns of platinum group elements in sulphides show that sulphide segregation is one of the important mechanisms for the fractionation of platinum group elements in upper mantle derived material during partial melting.
