| 摘 要： | 攀西地区以良好的铂族元素(PGE)成矿地质背景，而成为我国铂族元素找矿热点地区之一。本文在建立攀西地区铂族元素矿床地质概念模型的基础上，用地理信息系统(GIS)分析了该地区的铂族元素成矿地质条件，包括地质构造、峨眉山玄武岩、基性一超基性岩和铂族元素地球化学异常特征。指出研究区的深大断裂对铂族元素的富集表现出很好的控制作用，峨眉山玄武岩为铂族元素的矿源层之一，岩浆岩为铂族元素的富集提供了成矿物质及成矿能量。

| Abstract: | Panzhihua-Xichang area is one of the possible regions in China where PGE deposits could be explored, because of its good PGE ore-forming geological backgrouds.In this article, model of geological conception in Panzhihua-Xichang area is established, and then the authors used GIS as the tool to analyze the PGE ore-forming geological conditions,including geological structure, Emeishan basalt, basic-ultrabasic rock and PGE geochemical abnormal.The conclusion is that the enrichment of Pt,Pd is controlled by big and deep fractures, that Emeishan basalt is one of the sources of Pt and Pd, and that basic-ultrabasic rock offers the ore-forming elements and the ore-forming energy. |
