Abu Tartur phosphorites are considered as highest-grade in Egypt (attain average of 25 wt.% P 2 O 5) and considered as one of the most important factors in development in Abu Tartur area.Preliminary exploration of the mining area (about 108 km 2) led to an estimation of 987 million tons as economic reserve with an average of P 2 O …
The Abu-Tartur plateau lies 600 km southwest of Cairo and 50 km west of El Kharga Oasis, Western Desert (Fig. 1).It is located between Dakhla Oasis to the west and Kharga Oasis to the east (Fig. 2).The southern edge of the plateau overlooks the Nubia plain to the south, whereas it gently tilts northward forming the general surface of north …
The Abu Tartur phosphate mine occurs in the Dakhla basin. It is located about 650 km southwest of Cairo and 50 km west of Kharga Oasis in the Western Desert of Egypt (25°25′34″N and 30°05′08″E; Fig. 1). The Western Desert covers more than 65% of the whole Egypt extending from the Nile Valley to the Libyan border in the west.

Keywords Abu Tartur · Western Desert · Black shale · Glauconitization · Sea level Introduction The Abu Tartur area lies in the Western Desert of Egypt, mainly west of Kharga Oasis (Fig. 1). Phosphorite depos-its are of great economic importance and have been mined since their discovery in 1967. There are three conceptual
phosphates, the Nile Valley phosphates, and the Abu-Tartur huge phosphate deposits at Abu-Tartur plateau in the Western Desert. This plateau covers an area of about 1800 km2 between the Kharga and Dakhla oases (25°10' to 25°40'N, 29°25' to 30°10' E). In 2013, Zidan [4] suggested that Abu-Tartur phosphorite rocks were
