Abstract Hyperspectral Data (CASI/SASI) play an important role in identification of alteration zones for its abundant spectral information and high spatial resolution. In this study, the analysis of metallogenic geological conditions in Fangshankou-Laojinchang area indicates a good potential prospecting of the intrusion-related gold deposits. Anomaly extracting results of CASI/SASI indicate that seven types of alteration minerals, which are Al-high sericite, Al-middle sericite, Al-low sericite, limonite, dolomite, chlorite, epidote and calcite, are mainly developed in this region. Alteration mineral distribution and abnormal composition analysis show that Al-high, Al-middle sericite and limonite are developed in the Jintanzi deposit, which constitute the indicating alteration mineral assemblage for gold mineralization. Then the authors sieved the hyperspectral abnormal information and delineated the Fuangshankou as the ore-prospecting region. Meanwhile, multiple quartz veins which have gold mineralization were found in the field verification process. Therefore the selected indicating alteration mineral anomaly combined with the CASI/SASI is effective for the mineral prospecting.
