It is very important and difficult to extract geological altered information using remote sensing data. The method of Spectral Match Filter(SMF) in this paper was developed according to Ref. . The altered mineral spectra selected from standard spectral database were thought of as reference spectral vector in 0 mean domain. The filtering detector is established owing to the match degree between very one pixel in multiple band images and reference spectral vector in 0 mean domains. The altered information are segmented using both SMF and suitable threshold processing. Both a gold deposit at Dongtianshan of Xinjiang and a porphyry copper belt at Gangdese of Xizang are selected as test areas. Some altered minerals are extracted from ETM + data using SMF. The result shows that the locations of some altered minerals or altered minerals' composition are consistent with mineral deposit or ore spot. And the result also suggests the method be in good generality.
