Hyperspectral remote sensing is used to discriminate and extract widely the information of rocks or ore deposits. This principal composite analysis, which is based on composition-band using hyperspectral data according to the full spectral shape feature of different rocks, is very effective to extract the information of different rocks. The first component (PC1) of PC transformation contains more spectral information than others. Suitable RGB composite used PC1 and combined the result of SAM, and then contrast enhancement. It can suggest and show the based rocks, altered rocks and ore deposits. This is a technique which is based on object-faced full spectral shape feature to discriminate the information for rocks or ore deposits. Finally, it gains better result at the Hougou gold deposit region than other techniques.
