Paper Abstract

The area under study is located in the southern part of the Central Iranian Volcanic Sedimentary belt and covers an area of about 488 sq. kms. Sar Cheshmeh and Darrehzar areas with known mineralization and alteration are chosen as control areas. Airborne geophysical data -- radiometry and megnetometry -- and ETM+ data has been integrated and analyzed using fuzzy classification. This type of classification is suggested for remote sensing data, but it can also be used for classification of combined airborne geophysical and satellite data. After defining the training areas (Sar Cheshmeh and Darrehzar areas), the entire region is classified into altered and unaltered aras. This analysis is found useful for exploration of porphyry type deposits in the Central Iranian Volcanic Belt, where most parts of this belt is surveyed by airborne geophysics.
