| Abstract: | Taking a granite-type uranium deposit in south China as an example,thermal infrared data of ASTER is used to quantitatively retrieve the SiO2 content of the rocks after radiometric calibration,atmospheric correction and separation of the temperature and emissivity.According to the inversion map,strong silicified fault zones,the distribution area of granite and the red beds was identified,and the results have been validated in the field. |
