Um Radam area is located 160 km west Halaib City at the extreme southern part of the Egyptian Eastern Desert. The area is occupied by two major lithotectonic units; the ophiolitic rocks and the ophiolitic melange. These rocks form alternating NW-SE trending refolded sheets separated by major thrusts and are intruded by diorite-tonalite-granodiorite rocks and younger granites. Detailed analysis of regional, major, minor and microscopic structures reveals occurrence of three phases of deformation D1 , D2, and D3. Applied image processing and enhancement techniques, including principal component analysis (PCA), band rationing, and fast Fourier transform (FFT) substantially improved visual interpretation of ASTER and ETM+ imagery data for reducing redundant information in highly correlated bands and aiding accurate mapping of the different lithological units and structural elements in the area |
