Abstract

The present paper studied the stratigraphic succession of Infra-Cambrian Taba Formation overlain
by Sarbit El Khadim, Abu Hamata, Adedia and Um Bogma formations. The distribution of Taba Formation
at the study area comprises, Khaboba, Gabal Adedia, El Ferah, El Marahil, Gabal Hemeiyir and Ma’ein
localities. Gold is recoded mineralogically and geochemically at Khaboba locality. Also the gold is
recorded at the sandstone of Sarabit El khadim (4.5ppm) and the dolostone of Um Bogma Formation
(9.7ppm). The radiometric survey recorded thorium in Taba Formation up to 700 ppm. Also, thorium is
predominant in sandstone of Adedia Formation at Ras El Homara and Syniea. The chemical analyses
recorded uranium up to 1000 ppm in sandstone of Adedia Formation at Sarbit El Khadim locality
(Temple) for the first time.
