The mineralized complex which host Zhubu medium-sized Cu-Ni-PGE deposit is a mafic-ultramafic intrusion, intruded the schists and granitic-gneisses of Yuanmou Group. This paper provided new test results on major elements, trace elements, platinum-group elements (PGE) and Sr-Nd isotopes for some rocks and ores in the intrusion. The major and REE elements of the rocks show a tholeiitic evolution trend. The samples enrich in LREE and indicate a marked and weak negative anomalies for Sr and Nb, respectively. The inversion of magma evolution show that the primary magma is a picritic melt. The mineral cumulus and magma evolution also exit in the chamber, formed peridotite at the bottom and gabbros on the top, respectively, with pyroxenite and olivine- pyroxenite in between.
