四川丹巴地区Cu-Ni-Pt族元素矿床rn矿石组构与成矿期次

摘要

In the Cu-Ni-Pt deposit of the basic-ultrabasic rock ty pe of the Danba area, there exist various minerals with platinum group eleme nt. The deposit can be divided into three metallogenic epoches and four metallizin g phases by studying the characteristics of the ore texture and ore structure unde r a microscope. The platinoid minerals formed in the basic-ultrabasic magmatic activity stage. The paper also discusses the succession that minerals formed.%四川丹巴地区基性、超基性岩型Cu-Ni-Pt族元素矿床中，含有 多种铂族元素矿物。 通过显微镜下矿石结构构造等特征的研究，将矿床划分为三个 成矿期四个成矿阶段，铂族矿物均形成于基性、超基性岩浆活动期。文章还讨论了矿石矿物 的生成顺序。
