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
