普朗斑岩型铜矿是云南格咱岛弧成矿带中印支期斑岩型铜矿床的典型代表。本文应用聚类分析、因子分析方法对普朗斑岩型铜矿成矿岩体中微量元素进行了分析和科学分类。根据普朗复式斑(玢)岩体的地质条件和微量元素地球化学特征，从理论角度定性分析和定量分析均确定了普朗复式岩体存在明显的Cu-Au-Ag矿化异常，主成矿元素Cu与 Au 、Ag、Mo、W等具有较好的相关性，且局部存在中―低温的Pb、Zn矿化异常组合。矿床的形成与印支期中酸性斑(玢)岩体的侵入有密切的联系，成矿作用具多期多阶段性。

Pulang porphyry copper deposit is a typical Indosinian porphyry copper deposit in Geza island arc metallogenic belt of Yunnan.This paper analyzed and categorized the trace elements in ore-forming rock body of Pulang porphyry copper deposit by applying cluster analysis and factor analysis.Based on the geolog-ical conditions of composite porphyry (porphyrite)rock bodies and geochemistry characteristics of trace ele-ments,this paper confirmed obvious Cu-Au-Ag mineralization anomalies occurred in Pulang composite rock bodies through qualitative and quantitative analysis,and it also suggested a good correlation of the main met-allogenetic element Cu with Au,Ag,Mo,and W,as well as low-intermediate Pb-Zn mineralization anoma-lies association occurred in parts.The formation of the deposit has close relationship with invasion of In-dosinian intermediate acidic porphyry (porphyrite)rock bodies,and the mineralization is characterized by multi-phase and multi-stage.
