Abstract: According to SAI mineral absorption index model (Jinnian Wang, 1996), this paper analyzes gold, copper spectral curves of the main alteration mineral parameters and quantifies their spectral absorption characteristics. The main quantitative indicators are as follows: SAI, absorption width, absorption depth, absorption position, absorption symmetry. Synthesizing the ENVI function and the IDL language based on ENVI platform develops alteration mineral extraction module MineralExtractModule. In addition the experiment proves that the module can be quickly and accurately identify mineralizationrelated alteration minerals using the spectral absorption features, so realizes the goal of using imaging spectroscopy to extract alteration minerals quickly and automatically.

Key words: SAI, alteration information extraction module, IDL
