Abstract The ratio images were made to enhance the information of wallrock alteration by utilizing the spectral characteristics of wall rock alteration of gold deposits. The ratio images were Composed to concentrate the information of wall rock alteration which has been enhanced and make the gold deposits information to be obvious in order to survey the gold deposit from remote sensing data directly.
