Description
The present study deals with the uranium mineralization found in bostonite of north Wadi Kariem and the surrounding areas, Central Eastern Desert. The structure and geology of the host rock and the relationship between the uranium mineralization and the country rock are also described.<BR>The radioactive minerals in north Wadi Kariem and the surrounding areas occur in cracks and fissures of alkaline volcanics mostly of Carboniferous age. The mineralized structural features are caused by a deformation phase that created openings for solutions. Primary uranium minerals are coffinite and sooty pitchblende. These are found with sulfide minerals like pyrite, chalcopyrite, sphalerite, molybdenite, and galena. Hematite, quartz, calcite, psilomelane, and chlorite are the most common gangue minerals in the studied area.<BR>It is suggested that the precipitation of uranium was more favoured by the existance of structural traps rather than the chemical composition of the host rock. The deposition of uranium had been repeated during the latest stage of tectonic activity probably in the Carboniferous-Permian period.
