| Abstract: | Landsat TM 1,2,3,4,5,and 7 measure the reflected energy of rocks. TM6, the thermal infrared band, measures the emitted energy of rocks. The combinating use of these properties to distinguish rock types through TM image processing and infromation extracting has been tested by the authors in Xinjiang and Hebei. There is an obvious difference between the gold bearing rocks and other rock types in color in the composed image of multiband ratio and thermal infrared image in the Savayaerton area, Xinjiang. The method had been used in the other regions of Hebei and Xijiang and achieved remarkable results. |
