本文综合大量实际资料,总结了超镁铁岩建造纯橄榄岩中铂族元素矿物共生组合、化学成分及其演化的规律.论述了地壳范围内侵入体形成的晚期阶段辉长岩对于铂族元素矿物及其围岩纯棋榄岩的改造作用有重大影响.提出了一个在地幔还原性流体作用于铂族金属原生固溶体条件下岩石围中铂族元素分异的新模式.
In this paper, a large number of actual data are summarized and the law of the symbiotic composition, chemical composition and evolution of the platinum group element minerals in the ultramafic rocks is summarized.The effects of the gabbro on the platinum group elements Minerals and their remolding effect on the pure rock of peridotite.A new model for the differentiation of platinum group elements in the rock mass under the action of the mantle reducing fluid on the PGMs was proposed.
