Abstract

Abundant spectral and continuous spatial information of the satellite TM data is being applied

extensively. On the basis of analyzing spectral characteristics of TM image data and according to spectral

characteristics of rocks and ores as well as the theory of extracting information from remote sensing data，this

paper utilized such methods as band ratio, principal component analysis and principal component analysis after

ratio strengthening to extract mineralization-alteration information. Through sieving and evaluation, the

prospecting target can be delineated and the remote sensing map can be drawn.
