| 摘 要： | 传统的化探异常提取方法对埋深较大的隐伏矿床的弱异常难以突现，文章选择云南巧家茂租铅锌矿区作为研究试验区，将遥感影像信息与勘查地球化学方法相结合，通过对渗滤异常特征进行研究，选择有利的指示元素，运用地球化学多元分析，实现对渗滤异常的弱异常信息进行增强。该方法对主攻矿床类型明确，探测深度及找矿难度较大的地区的找矿工作有较好的指导作用。

| Abstract: | The traditional geochemical anomalies extraction method cannot proj ecting the weak anomalies of the buried hidden ore deposit This paper taking Maozu Pb-Zn mining District,Qiaojia,Yunnan as the study area.It combine Image informations of remote sensing with geochemical prospecting techniques.Selection of indicator elements of effective base on the features research of the leakage anomalies.To achieve the purpose of enhanced information of the weak anomalies by the multivariate analysis of geochemistry.The methods in this paper has better guiding to the ore prospecting of the main deposit type clear in the biggish detection depth and prospection difficulty area. |
