The phosphate resources in Egypt alone exceed 3 billion metric tons. Two-third of these three billions occur only in the Abu-Tartur area. Among the phosphorite deposits in Egypt, the phosphorites of the Abu-Tartur area are characterized by high contents of iron ranging from 3 % to 7 % with an average of 5 %.

In the Western Desert, Abu Tartur phosphorite deposits are considered as the largest and thickest deposits in Egypt. The geology of Abu Tartur area has been described by many authors [9–14]. The Duwi and Dakhla formations persistently extend along the southern escarpments which bounded the Western Desert southern escarpments which …

The Upper Cretaceous economic phosphates of Abu Tartur are affected by chemical weathering which imparts brownish hues to the surface exposures. Weathering is responsible for a series of mineral alterations as well as mobilization of several trace elements. ... Mineralogy and geochemistry of the phosphorites of Abu Tartur, Western …

The high S/C values in the Abu Tartur section indicate that a large amount of the organic matter was consumed via sulfate reduction under dysoxic and anoxic marine conditions. This interpretation ...

The leaching of rare earth elements (REEs) from Egyptian Abu Tartur phosphate rock using phosphoric acid has been examined and was subsequently optimized to better understand if such an approach ...

In the present study the effects of weathering on glauconite were studied on samples of the Abu Tartur phosphate mine, located 650 km southwest of Cairo and 50 km west of El Kharga City, Egypt, in ...

near Abu Tartur is largely responsible for the signifi cant rise in p roduction. The proved reserves of the pho sphate o re in Egypt amounts to 2.780 billion tons and h ence becoming the th ird ...

This investigation characterizes stone point production and use at PPNB Halula.Ballistic attributes indicate that Byblos points might have been used as dart-points.Expansion of darts use is synchronous with consolidation of agriculture in the region.Large tanged points made on bidirectional blades constitute the most characteristic tool type during the Pre …

The Duwi Formation in the Red Sea, Nile Valley and Abu-Tartur areas is subdivided into lower, middle, upper, and uppermost members, based on lithology and the occurrence of ravinement and subaerial erosional surfaces (Fig. 4).The productive phosphorite beds occur in the lower member in the Abu-Tartur area and in the …

The Abu-Tartur plateau, study area, is considered to be an important phosphate mining site that contains two thirds of the total phosphate reserve of Egypt estimated at 1billion tons and distributed through 112 km 2 of the total plateau area 1200 km 2 (Baioumy, 2002). The mine wastes are represented by phosphate rejects along with …

Egypt's Prime Minister Mostafa Madbouly met Wednesday with officials to discuss the progress of a phosphoric acid production project in the Abu Tartur plateau in the New Valley governorate.

In Egypt, the only SSDSs studied in detail occur in Neogene sediments of the Red Sea (Plaziat et al.,1990).Our work reports SSDSs for the first time in Upper Cretaceous sedimentary rocks (Quseir and Duwi formations) of the Abu Tartur area in the Western Desert of Egypt, and provides detailed descriptions and documentation of the SSDSs …
