PGE Characteristics of Cu-rich Ores in the Jinchuan Cu-Ni Sulfide Deposit and Its Genesis
摘要
Abstract
The Jinchuan intrusion hosts the largest single magmatic Ni deposit in the world. Net-textured sulfide ores are the main ore type, Cu-rich ores are nest-like distribution in the ore deposit. Spatial distribution, ore structure, composition of sulfide and PGE geochemistry of Cu-rich ores, the authors put forward its genesis: sulfide experiences Mono-Sulfide Solution (MSS) at later stage, the residual sulfide with Cu-, Pt-, Pd-rich concentrates at local space by gravity differentiation or tectonic activities. According to statistics and modeling of more than 300 PGE data, the PGE concentrations of the Jinchuan parental magma are concluded: Os=0. 355×10-9, Ir=0. 267 × 10-9, Ru=0. 277 × 10-9, Rh=0. 144 ×10-9, Pt = 4.94×10-9, Pd = 2.32×10-9, Ni = 338×10-6, Cu= 174 × 10-6. The average R factor of the Jinchuan ore deposit is 567, which is higher in ore body 1 and 24 than ore body 2.关键词
