Abstract
The present paper studied the stratigraphic succession of Infra-Cambrian Taba Formation overlainby Sarbit El Khadim, Abu Hamata, Adedia and Um Bogma formations. The distribution of Taba Formationat the study area comprises, Khaboba, Gabal Adedia, El Ferah, El Marahil, Gabal Hemeiyir and Ma’einlocalities. Gold is recoded mineralogically and geochemically at Khaboba locality. Also the gold isrecorded 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 ispredominant in sandstone of Adedia Formation at Ras El Homara and Syniea. The chemical analysesrecorded uranium up to 1000 ppm in sandstone of Adedia Formation at Sarbit El Khadim locality(Temple) for the first time.
Highlights
The study area is located between lat. 28o 50'-29o 05' N and long. 33o 15'-33o 45' E
Thorium is associated with basal conglomerate of Taba Formation, sometimes with sandstone of Adedia Formation and shale of Abu Hamata Formation
The basic dykes in the study area affecting on localization of U especially at the sandstone closed to the basic dyke as at Zobeir -Lehian, it reaches up to 140 ppm in sandstones of Adedia Formation while at Gabal Hemeiyir reaches to 180 ppm in sandstone of El Hashash Formation
Summary
The study area is located between lat. 28o 50'-29o 05' N and long. 33o 15'-33o 45' E. Hassan et al (2013) gives Infra-Cambrian to basal conglomerate of Taba Formation at Ghazalani area. Thorium is associated with basal conglomerate of Taba Formation, sometimes with sandstone of Adedia Formation and shale of Abu Hamata Formation. Uranium is associated with upper most part of sandstone of Adedia Formation and Um Bogma Formation. REEs are associated with Taba, Adedia, Um Bogma and Magharet El Maiah formations. Mn-Fe ore are associated with Um Bogma Formation especially within lower member and was discovered by Baurman (1869). Five samples were analyzed for gold concentration representing basal conglomerate, sandstone, shale, ferruginous sandstone and dolostone. The thickness of Taba Formation decreased toward the West to reach about 1.5m at Khaboba locality. The present work confirms the stratigraphic assignment of Infra-Cambrian to the Taba Formation (El Kelani and Said, 1986-1990). Infra-Cambrian base on the occurrence of Skolithus at south of Gabal Haithiat (through Saint Kathrine-Nuwieba high way)
