| 摘 要： | 在总结前人工作的基础上,论述了PGE在超镁铁岩中的分布范围以及在部分熔融、结晶分异和蚀变作用过程中的行为规律。在部分熔融和结晶分异过程中,Ir组PGE(Os,Ir,Ru)表现为相容性,除寄存于硫化物外,还可寄存于难熔相中如橄榄岩,铬铁岩等;Pt组PGE(Rh,Pt,Pd)表现为不相容性,主要寄存于硫化物相中,且优先进入熔体中。在蚀变作用过程中,PGE的行为主要受其溶解度的控制。

| Abstract: | On the basis of summarizing former relative works, this paper manily discusses the PGE distribution in ultramafic rock and the behaviour during partial melting, crystal frac-tionation, and alteration. The Ir-group(Os, Ir, Ru) showes compatibility, and has both hosts of sulphide and refractary mass e. g. peridotite and chromitite etc. ; the Pt - group (Rh, Pt, Pd)showes incompatibility, and only one host of sulphide, and precedently comes into molten mass during partial melting and crystal fractionation. The PGE behaviour during alteration is controlled by the dissolubility. |
