摘要
铜、钴、镍及铂族元素矿化的多阶段性是金宝山铂矿床的显著特征。本文划分出两个矿化期、五个硫化物形成阶段和四种硫化物组合类型(原生组合、交代组合、高温热液组合及低温热液组合)。阐述了硫化物组合演化的规律性,以及以岩浆熔离为主、热液作用为辅的矿床成因观点。
The Jinbaoshan platinum deposit is obviously characterized by the multi-stage Cu-Co-∑Pt mineralization. Two mineralizing periods, five sulfide-forming stages and four sulfide assemblage types (primary assemblage, metasornatic assemblage, hypothermal assemblage, and low temperature hydrothermal assemblage) have been distinguished. The evolution of sulfide assemblages is also discussed. It is postulated that liquid magma immiscibility and hydrothermal process may genetically explain the formation of this' deposit.
