铂族元素矿床特征及成因分类探讨

在收集国内外铂族元素矿床地质特征的基础上,审视了国内外不同学者对铂族元素矿床的分类方案,综合矿床容矿岩石类型、共生元素组合、矿化类型和矿床类型并结合形成环境,对铂族元素矿床进行了系统的总结和分类,划分为四类十二亚类。同时重点论述了具有开发前景的典型铂族元素矿床的基本特征、成矿物质来源和形成环境及成矿的关键问题。

The deposit geologic features of the platinum group element and its genetic classification

On the basis of the characteristics of platinum group element (both inside and outside the countries),the classification of the platinum group element deposits is rechecked According to the host rock type of the deposits,paragenetic element association,mineralized type and metallogenic conditions,the platinum group element deposits are systematically summed up and classified They are classified into 4 types and 12 sub-types Meanwhile,the basic characteristics of typical platinum group element deposit with the developmental prospect,metallogenic resources and metallogenic conditions are discussed in this paper
