Abstract  

The study area is located in Lima South Central,Peru,and the south of Andean porphyry belt northern,with good copper polymetallic mineralization geological conditions.Based on ASTER multispectral satellite data and the spectral characteristics of altered minerals region,using characteristic band combination of principal component analysis method completed the altered minerals assemblage information extraction.Using this method,extracted Al\|OH altered minerals information,such as sericite,kaolinite,montmorillonite,illite,alunite ,et al,and propylitization alteration minerals information,such as chlorite,epidote and carbonate (calcite and dolomite).While using interactive interpretation technique in the study area to carry out geological interpretation of remote sensing,which combined with regional geological characteristics,had a comprehensive analysis of remote sensing indicator mineral information including ore\|controlling linear structures,circular structures,ore\|bearing strata and alteration mineral assemblages.In addition,remote sensing indicator mineral information conducted a comprehensive  prospecting prediction,and delineated favorable prospecting area.Comparing with the ground stream sediment geochemical mapping and high\|resolution satellite images,which indicates that the delineation of remote sensing prospecting area provides important reference basis for exploration in the development of ground mineral.

Key words:  ASTER satellite data      Alteration mineral assemblage information      Remote sensing indicator mineral information;Prospecting prediction
