Prospecting of deposits by studying of alteration zones has agreat importance. Giventhattheidentificationof alteration zones of areas, which have iron potential has beenlessstudied usingremote sensingdata, thereforeto achievethe identificationofalterationsurroundingthe HajiAbadiron deposit in the northeast of Sonqor City,, in the Kermanshah Province processinganalysisofsatellite images such as False Color Composite (FCC), Band Ratio (B.R), Directed Principal Component Analysis (DPCA) and Spectral Angle Mapping (SAM) techniques on short wave infrared and visible near infrared bands (SWIR+VNIR) of ASTER (AdvancedSpaceborne Thermal Emission and Reflection Radiometer sensor) were used. Also by comparing USGS (United States Geological Survey) minerals standard reflection curve with studied region’s curves, it can be seen that the curve of thepropylitic alteration minerals have more agreement with chlorite and epidote, and the phyllic-argillic alteration have more agreement with illite and kaolinite, and iron-oxides have more agreement with goethite and hematite.The results accuracy wasapproved by fieldandmicroscopicstudies and represents thepatterns ofalteration aroundthedeposit.
