TIMS data were acquired on November 1990 in Jinchangyu region. By meansof computer image processing such as principal components transformation and decorrela-tive transformation, etc., some important geological information such as gold mineralizedzone, granitic, plagioclase gneiss, clay grouting, silicification and fault system is taken out,and two gold mineralized zones in the research area found. The results show that the goldmineralization in this region is controlled by the NNE fault system. It is proved that theThermal Infrared Multispectral Scanner (TIMS) data are very efficient in discrimination ofrocks, gold mineralized zones and enhancement of fault information. TIMS remote sensingtechnique has great potential in geological applications.
