“…This unit in both studied sections is compared with the same unit in the Dababiya section (GSSP, Aubry et al, 2007) and many other Egyptian regions (Table 3). Various authors assigned an Ypresian age to this member (Aubry et al, 2007; Obaidalla et al, 2017). Also, in the studied sections, the presence of the upper part of P .…”

“…This member corresponds to that of Dababiya section (GSSP, Aubry et al, 2007) and has a wide geographic distribution in various Egyptian areas (Table 3). Most authors assigned a Thanetian age to the El Hanadi Member (Abdel Razik, 1972; Aubry et al, 2007; El‐Younsy et al, 2017; Obaidalla et al, 2017). Moreover, the El Hanadi Member herein encompasses the upper half of Acarinina subsphaerica Subzone (P4b), the Acarinina soldadoensis/G .…”

“…This member is comparable with the same unit in the Dababiya Section (GSSP) and other Egyptian areas (Table 3). Many authors assigned an Early Ypresian to this member (e.g., Aubry et al, 2007; Dupuis et al, 2003; Obaidalla et al, 2017). The occurrence of the Acarinina sibaiyaensis Zone (E1) and the Pseudohastigerina wilcoxensis/Morozovella subbotinae Zone (E2) in Wassif and Um El Huwaitat sections confirms the Early Ypresian age for the Dababiya Quarry Member (Figure 2 and Table 3).…”

The Palaeocene-Eocene succession in southwest Safaga, Eastern Desert, Egypt has been studied to determine its lithostratigraphic units, biostratigraphic zonation, microfacies association, and depositional environments. The variation in lithofacies allows the subdivision of the Danian-Ypresian interval into four lithostratigraphic units that are arranged, from base to top, as the Dakhla Shale (only its upper part), Tarawan Chalk, Esna Shale, and Thebes Formation (only its lower part). Moreover, the Esna Shale is further subdivided into four members, arranged from base to top, as El Hanadi, Dababiya Quarry, El Mahmiya, and Abu Had. The depositional setting is interpreted to primarily reflect the relative sea-level changes. The planktonic/benthic (P/B) foraminiferal ratio is indicative of oscillations of depositional settings in normal open marine conditions, ranging from shallow inner to outer neritic environments. Biostratigraphically, the Palaeocene-Eocene succession in the studied area is subdivided into 12 biozones and subbiozones. These are correlated with the standard biozonation of the Palaeocene-Eocene. Deposition of the Palaeocene-Eocene succession in the studied area took place on a relatively stable shelf. Three lithofacies were recognized: shale, marl, and limestone. The shale lithofacies is differentiated into two sub-lithofacies; pure shale and calcareous foraminiferal shale, whereas marl lithofacies contains abundant planktonic foraminifera. The encountered carbonate rocks comprise eight microfacies types. In addition, the studied interval is correlated with the Global Standard Stratotype Section and Point in the Dababiya section, south of Luxor, Egypt.
