Based on the field experiments and demonstration of key instrument and equipment for deep explo- ration��the image fusion technology is conducted to extract geological information�� Considering spatial registration of satellite remote sensing and gravity anomaly�� the image fusion and analysis between gravity anomaly and ETM + da- ta are carried out by HIS image fusion�� The results show that structural features��namely spatial distribution charac- teristics��between remote sensing image and gravity anomaly are different�� Furthermore��the inversed geological in- formation obtained by localizing gravity anomaly from remote sensing data��provides a scientific basis for the field experimental reconnaissance by utilizing detecting instrument and equipment for deep exploration��
