| 摘 要： | 采用硫镍火法试金(NiS-FA)结合电感耦合等离子质谱(ICP-MS)分析了太白金矿硫化物和含金角砾岩中铂族元素的含量,结果显示,与秦岭地区八卦庙相比铂族元素含量较高,而低于原始地幔,其中铂(Pt)、钯(Pd)、钌(Ru)富集,并结合前人研究资料对铂族元素的来源和迁移机制进行探讨。铂族元素可能受深源的影响,IPGE(Ir、Os、Ru)可能主要以硫化物形式存在而PPGE(Rh、Pt、Pd)可能主要以单质存在。

| Abstract: | The content of platinum-group elements(PGE) in samples of sulfides and gold-bearing breccia from the Taibai gold deposit was determined by the nickel sulfide fire assay and inductively coupled plasma-mass spectrometry(ICP-MS).The results show that the PGE content in these samples is higher than that in the Baguamiao gold deposit,Qinling,but lower than that in the primitive mantle.Among the PGE,Pt,Pd and Ru are richer.According to the above-mentioned analysis,combined with the previous study of the sources and transport mechanism of the PGE,the authors think that the PGE may have been subjected to the deep sources,of which the IPGE(Ir,Os and Ru) might occur in the form of sulfides,while PPGE(Rh,Pt and Pd) might occur as simple substance. |
