The contents of natural radionuclides 226 Ra, 232 Th and 40 K were measured in sedimentary phosphate rock samples Abu-Tartur phosphate, Western Desert Egypt by using gamma spectrometry NaI Tl 3 3.Phosphate and environmental samples were collected from Abu-Tartur phosphate mine and the surrounding region.
Jul 01, 2015 The oldest sedimentary rock in Abu Tartur plateau is the cross-bedded non-fossiliferous sandstone of the Nubia formation Cenomanian to pre-Campanian. It is conformably overlain by the variegated shales of the Quseir formation which is overlain by the Duwi phosphorite formation of late Campanian to early Maastrichtian in age 18 .

treatment of Abu-Tartur phosphate rock using HNO 3. The results show an assessment of complete dissolution of the lanthanides occurs in the phosphoric acid produced by H 2SO 4. A significant benefit of Abu-Tartur phosphate rock processes lies in their relatively high content of lanthanides averaging
Results In Egypt, the natural phosphate rock is located in Sebaiya Nile Valley, Safaga Red Sea, and Abu Tartur Western Desert. The higher the organic matter contents in soil, the better dissolution of the PR. Legumes are particularly suited for the use of PR. Biological solubilization of phosphate rock is more environmentally friendly
This study is about experimentally analyzing different samples of potential oil shale fields in Egypt. Samples that are analyzed in this project are from two locations in Egypt Quseir-Safaga and Abu-Tartur Western Desert, and they are compared to one of the best oil shale fields in the world, which is from Green River Formation Colorado.

Apr 01, 2013 The Abu Tartur phosphorites have higher contents of TiO 2, Al 2 O 3, Fe 2 O 3, K 2 O, Co, Nb, Pb, Sr, Th, Y, and Zr and lower SiO 2, Ba, and U contents as compared to those in the Red Sea and Nile Valley areas. The positive correlations between Al 2 O 3 and TiO 2, K 2 O, Nb, Y, and Zr suggest the detrital origin of these constituents.
