云南东川——地区铂钯元素地球化学特征及其找矿探讨

摘要

Investigation and river sediment sampling reveal high background value, strong and dense anomalies of PGE in Dongchuan-Qujing area. The anomalies are mainly controlled comprehensively by strata, structure and volcanic apparatus occuring in clusters striking in NE or EW directions and showing favourable geological conditions of PGE ore formation. Ore prospect should be directed to PGE deposits both related to Emeishan basalt and black shale sequence.%对云南东川&曲靖地区铂钯元素成矿地质背景的分析和水系沉积物铂钯元素地球化学特征的研究表明,该区Pt,Pd元素背景高、异常密集、强度大;异常主要受地层、构造和古火山机构的综合控制,呈NE向成带分布和EW向成串出现;该区铂族元素成矿地质条件有利,具有一定的找矿前景;要同时重视找寻与峨嵋山玄武岩有关和与黑色岩系有关的两类铂族矿床.
