Abstract
The Late Cretaceous to Paleocene periods in the South Eastern Desert along the Nile Valley in Egypt, specifically in the Owaina, Kilabiya and Nag el Qada sections, have been examined to understand the planktic and benthic foraminifera. The analysis of foraminifera was conducted to constrain the biostratigraphy and infer the paleoenvironmental conditions Lithostratigraphically, the Owaina section is subdivided to three formations, from base to top: Quseir , Duwi formations and Sharawna shale member of the Dakhla Formation. The Kilabiya section is represented by the Owaina Shale Member of the Dakhla Formation, whereas the Nag El Qada succession is represented by the Tarawan Formation. Biostratigraphically, 66 planktic foraminiferal species belonging to 20 genera have yielded twelve planktic foraminiferal zones and sub-zones, including 6 in the Cretaceous and six in the Paleocene. They are, in ascending order: Globotruncanella havanensis (CF9), Globotruncana aegyptiaca (CF8a), Rugoglobigerina hexacamerata (CF8b), Gansserina gansseri (CF7), Contusotruncana contusa (CF6) and Pseudotextularia intermedia (CF5) of the Late Cretaceous, as well as Praemurica inconstans (P1c), Praemurica uncinata (P2), Morozovella angulata -Igorina albeari (P3a), Igorina albeari (P3b), Globanomalina pseudomenardii/Acarinina subsphaerica (P4a) and Acarinina soldadoensis/Globanomalina pseudomenardii (P4c) of the Paleocene. The results of lithostratigraphic and high-resolution biostratigraphic studies allowed for the identification and definition of the Campanian/Maastrichtian (C/M), Danian/Selandian (D/S), and Selandian/Thanetian (S/Th) boundaries in the studied sections.
