Petrological and geochemical examination of Upper Cretaceous chalks from the Abu Roash area and Bahariya Oasis (Egypt) provide insights into factors which control porosity development in fine-grained calcitic carbonates. Petrological studies indicate that primary skeletal fabrics of coccoliths and foraminifera in micrites of Abu Roash are well preserved. In contrast, primary skeletal fabrics of...

The genus Vanhartenidia Lelej, 2006 is newly recorded from Egypt. A new species, V. mandishaensis El-Torkey & Soliman, sp. nov. is described and illustrated from Bahariya Oasis (Giza, Egypt).

a total of 29 species in 16 genera and 8 subfamilies of the braconids (hym., braconidae) were collected from alfalfa fields in bahariya and farafra oases (western desert, egypt) these species were identified, together with details of the sites where they were found and an indication of their relative abundance in each site. among the samples, 4 species in 4 genera and 3 subfamilies are recorded...

In Egypt, nineteen water springs with temperatures exceeding 35 degrees C, which can be considered thermal waters, were reported. The radiological aspects of thermal water in three northern regions of Egypt (Gulf of Suez, Cairo, and Bahariya Oasis) were investigated. The activity concentrations of natural radionuclides of 226Ra, 40K, total uranium and 210Pb (210Po) in water samples were determi...

The type section of the Lower Cenomanian Bahariya Formation at Gebel El-Dist (Bahariya Oasis, Western Desert), Egypt, comprises claystones, mudstones, siltstones and sandstones deposited in fluvial-deltaic coastal plain, lagoonal, estuarine and shallow marine environments. The formation is characterized by an abundance of ferruginous sandstones that locally weather to form prominent iron crusts...
