Abstract  

The key point for gold exploration using remote sensing technology is the information extraction of ore-forming structures and spectral characteristics of ferrite oxides and altered hydrous minerals. On the basis of the remote sensing image processing software (ENVI 4.0) and by using a new quick, exact and effective method for extraction of gold mineralization and alteration information,namely "multivariate data analysis+ratio+PCA+DS+classification",the spectral characteristics of altered minerals can be extracted,and the influence of the vegetation can be suppressed. It is demonstrated that the gold mineralization and alteration information is in accordance with the known mine spot,and the method is very feasible.
