Geochemical analysis of Wuxing Cu--Ni--PGE deposit indicates that the rock samples have obvious characteristics of low content of SiO₂ (48. 36% ��52. 68%)and wide range of Al₂O₃ (1. 24% ��14. 8%)��Fe₂O₃T (3. 67% ��11. 31%)��CaO(6. 63% �� 21. 42%) and MgO(5. 52% �� 19. 15% ) with the m/f values range from 0. 86 to 8. 89��falling into the range of ferrous mafic-ultramafic rocks�� According to the Harker variation diagrams�� Wuxing rocks originated from fractional crystallization dominated by diopside minerals��meanwhile��middle-upper crustal contamination occurred in the same process of the fractional crystallization�� Geochemical characteristics of the trace elements show that the original magma came from depleted mantle source�� Fractional crystallization and contamination from crustal materials are contribute to the saturation of sulphur element��and the sulfides carry with metal elements liquate from silicate melts in the form of melts�� With the increase of magma the Wuxing deposit formed in shallow part of the crust finally��
