Title: Activity ratios as a tool for studying uranium mobility at El Sela shear zone, southeastern Desert, Egypt.
Authors: Abdel Gawad, Ahmed; Ibrahim, Eman
Abstract: The present work aims to integrating detailed geologic field studies with natural radionuclides activity ratios as a tool for studying uranium-mobility in three rock types at El Sela shear zone, southeastern Desert, Egypt. Natural radionuclides content have been measured by γ-ray spectrometry employing a shielded HPGe detector. This study revealed that U and some of its progenies were redistributed after the rock emplacements and subjections to several alteration processes. The acidic and alkaline alterations play their role in the redistribution of radionuclides in different rock types. The main alteration processes are the argillization, fluoritization, silicification and ferrugination with formation of visible U-mineralization.
