Abstract: The Gabal (G.) El-Niteishat area lies in the Central Eastern Desert ofEgypt which is known for various mineral resources and geological structures. UmmGheig, Umm Naggat, Umm Shaddad, Wadi (W.) Zeidun and Sigdit represent someimportant regions that contain mineral deposits in the study area. Variousfilters such as first vertical derivative (FVD), horizontal gradient magnitude(HGM), tilt derivative (TDR) and near-surface were applied to the airbornemagnetic data for the study area to deduce the structural lineaments andmagnetic source edges which were controlled by the presence of mineral deposits. Processed Landsat ETM+ images are usedfor delineating the rock unit boundaries that are exposed in the study areasuch as serpentinite, metagabbro, metavolcanics and metasediments. Also, band ratios, principalcomponent analysis (PCA) and false-color composite image (Crosta alterationimage) were applied to get specific results about the alteration zones. Thestructural lineaments analysis illustrated that the common trends that affectedthe study area were NW-SE, NE-SW, E-W and N-S. Integration of remote sensing and airbornemagnetic data exhibited the relation between mineralization and structurallineaments.
