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.
