Exploration for gold deposits in the Egyptian part of the Arabian Nubian shield : plate tectonics and remote sensing interpretation

The 2, 4, 7, 5/7, 5/1, 4/3, 2/7, and 3/1 bands and ratios composite TM images are successfully used to discriminate the rock units of the ophiolitic and island-arc assemblages, the cordilleran - extensional stages and associated regional alteration zones. Genetically, plate tectonics explained distribution of gold mineralisations in the Eastern Desert of Egypt in relation to the rock assemblages, stages and associated alteration zones
