The area under study covers an area of 640 km2
, located in the southern part of Iranian Volcanic-Sedimentary Belt. ETM+ images have been used for alteration mapping. Satellit images can be used for enhancing the areas with hydroxyl and iron oxide minerals. However field checking has shown that this method is not able to enhance all the areas with hydrothermal alteration. At the same time many of the altered areas do not have good signature in the geophysical data. In order to recognize such areas integration of remote sensing and geophysical data can be helpful. The Darrehzar Cu deposit is chosen as a control area. The data analysis and integration of geophysical and remote sensing data is performed by using directed principal components. This technique is found to be useful for the delineation of hydrothermaly altered areas with more confidence.
