Relationship Between Composition and Spectral Feature of Muscovite

The aim of this study is the exploration of the intrinsic relationship between chemical composition and spectral features of rocks and minerals so as to detect mineral micro-information based on the hyperspectral remote sensing technology.Based on rock and mineral microscopic identification,the authors analyzed spectral features of muscovite from the rock sample by using TSG geological spectrum analysis software,and studied the chemical composition of muscovite by means of electron microprobe analysis.On such a basis,spectral variational features of muscovite were statistically analyzed.The results indicate that the diagnostic spectral wavelength position of muscovite moves towards the long wavelength with the reduction of AlⅥ cations.
