Hejiadaling area is in Lujiang‐Zongyang volcanic rock basin in Anhui Province ,and there are many evidences of hydrothermal alteration in this area .In this paper ,the hyperspectral analysis meth‐ods such as Spectral Analyst of ENVI software and linear spectral unmixing(LSU) are used to process the data obtained by Advanced Spaceborne Thermal Emission and Reflection Radiometer(ASTER) for identifying minerals and rocks .The results from these methods show good match with the geological materials ,indicating that mineral and rock identification by using the data of ASTER is effective .The distribution maps of minerals and rocks are also made with the mixed pixel unmixing by LSU method .
