By using ASTER data and such methods for extraction of lithologic information as major composition image and the mineral index, a discrimination for and extraction of lithologic information has been made in the Wenquan Reservoir area of the East Kunlun orogenic belt. The results show that the major composition image and the mineral index can well reveal the composition of rocks. Clearly shown on ASTER images are lithostratigraphic units covering a relatively large area. ASTER images would prove to be an effective method for extraction of lithologic information in bedrock exposed areas, especially for carbonate rocks as well as sedimentary and volcanic rocks with varying SiO2 contents. But for the rock units of small thickness or altered rocks, the methods need to be improved.
