| Abstract: | Based on previous data and information,the author studied and summarized the features of spectrum curves and their geological significance of rocks(ores) from southern belt of Baishan area in Gansu Province in this paper.The main features and interpretation keys on remote sensing images related to gold mineralization-related rocks,structures and hydrothermal alteration in this region are discussed.The best wave combination model of TM color composite imagery for this region is TM7(red)+TM5(green)+TM4(blue).The result supplies useful information for further study and application on remote sensing techniques. |
