| 摘 要： | 用中子活分分析确定四川新街铂矿的矿化特征，用扫描质了探针作铂的微区分布研究。首次在该矿原位找到微米粒度的砷铂矿物。结果表明，新街铂矿为富铂钯型铂矿。微量铂主要以砷铂矿物独立存在。

| Abstract: | The occurence state of platinum in Xinjie Pt mineral deposit, Sichuan Province has been studied with. neutron activation analysis(NAA) and scanning proton microprobe(SPM). Platinum ore samples from the deposit were analyzed by NAA to understand mineralising features of PGE. Then the SPM was used to get microarea distributing features of platinum for the samples. It is shown that Xinjie Pt deposit is of rich Pt-Pd type where spenylite,occuring independently in the deposit, is one of major occurence states of platinum. |
