| 摘 要： | Primitive mantle-normalized Platinum-group elements (PGE) concentration patterns for the Zhengziyanwo intrusion and Dashibao Formation basalts are of positive slope, similar to most of the world-class magmatic Ni-Cu-PGE sulfide deposits. Characters of this intrusion and its related ores and Dashibao Formation basalts are their negative Pt-anomaly and high concentration of Rh relative to Pt and Pd, facts being interpreted to be the results of crystallization and fractionation of Pt-alloys and spinel phase-free crystallization history for the magma, respectively. PGE parameters of the Dashibao Formation basalts are consistent with the general trend of those found for the Zhengziyanwo intrusion, and this might infer a genetic link between them.
