///The Jinchuan Ni-Cu-(PGE) sulfide deposit is hosted by ultramafic intrusions in northwestern China. The central part of the Jinchuan intrusion (Ore Body 1) has a “tongue-like” shape in cross section and hosts ~56.8% of the known Ni resources. It is characterized by concentrically zoned, with net-textured ore surrounded by disseminated sulfide. Net-textured ore is dominant over other ore types in ore body 1^#. Based on 100% sulfide recalculation, different types of ore in ore body 1^# have high and low value characteristics of IPGE, and Pt vary largely, Pt/(Pt+Pd) ratios of most samples are out of (0.3-0.7). The Ni, Cu content variations of drill hole samples indicate that Cu-rich ores concentrated at base of net-texture ore body, and content of this two elements appears obvious negative relationships, Ni/Cu ratios vary largely in deep. The results reveal that the ore body 1^# was affected obviously by hydrothermal alteration. IPGE and small scale variations of Ni/Cu ratios are likely due to fractional crystallization of MSS.Small Cu-PPGE rich lenses and large scale variations of Ni/Cu in the deep part of ore body #1 may be the result of MSS fractionation or hydrothermal alteration.
