Abstract: With study on the characteristics of remote sensing images in work area, combined with comprehensive analysis of ground survey, the characteristics of RS image and interpretation results are systematically summarized for the intrusive rocks, metamorphic rocks and linear structures in the surveyed area. It is found that some geological units and geological phenomena are well interpreted, with accuracy rate over 70%. A set of effective working methods is concluded, which is proved valuable and irreplaceable in the regional geological survey.
