Abstract  

The study area is located at the north of Gaize county,Ali region,belongs to Ban Nu metallogenic belt.Natural and geographical environment in this area is very poor,and exists low level of geological research,slow progress in geological survey and mineral resource survey.Seen from the mine have been found,the main minerals of study area is placer gold,rock gold and copper and gold mine,but also distributs salt lakes and coal mines,this area boasts favorable mineralization background and great ore mineral potential.Therefore,prospecting in this area via remote sensing is an economical,convenient and effective means.This paper is supported by the ENVI software,according to the spectral characteristics of Aster multi spectral image data and alteration mineral assemblages,and make use of the methods of ratio and principal component analysis to draw alteration information of metal mineralization related to minerals and mineral assemblages from Aster remote sensing data.Geological data are integrated with the results of remote sensing image processing to analyze mining factors to divide prospective districts and delineate prospecting targets.

Key words:  Ban Nu metallogenic belt      Alteration      Aster remote sensing data      Geological structure
