By the using of geochemical methods and quantitative textural analysis，This paper studied the spatial distribution characteristics of platinum group elements in Jinchuan Ni-Cu-（PGE） sulfide deposit，discussed the dynamic behavior in the process of magma evolution，and the evolution of Jinchuan mafic-ultramafic magma .This study found that the spatial distribution of the platinum group elements showing a certain regular changes between four continuous ore bodies. Overall，there are a significant decrease in the value of Pd/Ir-Ni/Cu between the four ore bodies from west to east. Through?the analysis，the cause which effected the distribution is that the monosulfide solid solution（MSS） has experienced a process of crystallization differentiation during crystal fractionation. On the other hand，through quantitative textural analysis，found that the structure of No. 1 ore body is much more mature than No. 1 ore body，which suggested that the emplacement of the former one is much more earlier than the latter one. Integrated geochemical and magma dynamics information，finally obtained the conclusion that the moving direction of Jinchuan magma conduit system is along the strike of the intrusions from northeast to southeast.
