Analysis of imaging spectrometers data aqnired in the Pine Creek area, North 
Australia has shown the similar results. Geologicallj. it is assumed that the 
mineral featires of absorption band of 2. 130 and 2. 262 ti m extracted from MAIS should be the 
bnddingtonite the alteration associated with NH S and the iimonitiiaticn. sericiiation. and 
chloritixation. It is expected that the some area with above twin strong absorption bands are 
exactly coincided with the existed uraninm deposit and mining areas. The results of these 
analysis are shown in Fig. 4-4.
