Abstract Utilizing remote sensing imagery processing technology and mathematical statistic methods, this paper evaluated the spatial and radiation features of CBERS—02B satellite remote sensing imagery, and comparatively analyzed the main characteristic parameters with ETM+. Based on the above studies and integrated with aerial radioactivity data, the authors identified and mapped such spectral features of main ore-forming factors of uranium deposits as ore-controlling faults, hydrothermal alterations and plutons, and evaluated geological application potentials of CBERS—02B remote sensing imagery in the Taoshan granite-type uranium deposit.
