【 摘 要 】

The old surface and the fresh surface of the rock samples have been subjected to field spectrum test what should be compared indoor control spectrum test, and the mineral element test of the sample and the observation of the sample under thin film have been carried out. The spectral reflectance of old surface and fresh surface shows that the old effect has little effect on the spectral characteristics of rock minerals which affects the size of the reflectance. The difference are between the mineral elements and the spectral characteristics of the samples. The spectral characteristics and spectral indices of different samples have ex-tracted and the data have extracted for hyper-spectral data extraction of alteration information.
