One of the rare and natural phenomena in the world is the abundance of salt domes, especially in the folded Zagros zone. For many years, many researchers, especially researchers in the field of earth science, have sought to obtain more accurate information on various phenomena and sources of land, including salt domes, using advanced technologies. Konarsiah and Jahani salt domes are located in southwest of Firouzabad, Fars Province. Lithological units and green vegetation characteristics have been evaluated using band ratioings method on the reflected datasets of ASTER. In this research, Lithological units and green vegetation in salt domes enhanced using Relative Absorption Band Depth (RBD) in the datasets of ASTER. Lithological units of salt domes are mainly gypsum, salt, limestone, shale, marl and clay complexes. Enhancement of clay, carbonate, sulfate units and green vegetation were accomplished by RBD method. The results were compared with geological map, field observations and the accuracy of processing was evaluated.
