Abstract
Glauconite deposits are widely distributed in the Western Desert of Egypt. In the Bahariya Oasis, Cenomanian glauconites (Bahariya Formation) underlay the middle Eocene iron ore of Naqb Qazzun Formation, while the Eocene glauconites (Hamra Formation) overlay the iron ore. In the Abu Tartur Plateau, the Cenomanian glauconites (Qusseir Formation) underlay the upper Cretaceous phosphorites (Duwi Formation), while upper Cretaceous glauconites (Duwi Formation) overlay the phosphorite deposits.Although glauconit is the main mineral constituent of these deposits, distinct variations in the petrology, petrography, and mineral composition of the associated phases were reported. For example, Cenomanian glauconites from the Qusseir Formation occur as fine-grain flakes, while other glauconites occur as pellets. Upper Cretaceous glauconites from the Duwi Formation have high content of apatite. Cenomanian glauconites from the Bahariya Formation show relatively high contents of smectite.The variations among stud deposits on one hand reflect formational and/or diagentic conditions of these deposits and on the other hand suggest a wide range of applications of such deposits. Sandy deposits will be more suitable for water treatment, while P-rich deposits are more effective for agricultural applications.
