Biostratigraphy of the Upper Cretaceous rocks in Gebel Arif El-Naga, northeastern Sinai, Egypt, based on benthonic foraminifera

Maastrichtian-early Paleocene foraminiferal palaeobathymetry and depositional sequences at Gebel El Sharawna, south Luxor, Egypt

“…Most of these species have been recorded in Maastrichtian successions elsewhere, but may not appear in the Maastrichtian successions of the present study probably due to the shallow water environment of deposition. These species include Anomalinoides rubiginosus and Angulogavelinella avnimelechi (Hewaidy & Strougo ), Dorothia oxycona and Tritaxia midwayensis (see Shahin ; Ayyad et al ).…”

Foraminiferal Biostratigraphy, Paleoecology and Sequence Stratigraphy of the Upper Campanian –Lower Eocene (Ypresian) Succession at Gabal Qabeliat Section, Southwestern Sinai area, Egypt

“…This biozone is represented by the middle part of Abu Zeneima Member (Samples 37-66), and it attains about 28 m. It is assigned to Early Maastrichtian age as it is correlated with Rugoglobigerina hexacamerata (CF8b), Gansserina gansseri (CF7), Contusotruncana contusa (CF6), and Pseudotextularia intermedia (CF5) planktonic biozones. Bolivinoides draco miliaris Hiltermann & Koch was previously recorded from the Maastrichtian by Le Roy (1953), Said & Kenawy (1956), Shahin (1988), and Ayyad et al (1997).…”

“…The benthonic foraminiferal biostratigraphic studies of the Late Campanian-Early Eocene (Ypresian) time interval were carried out by many authors in/ out-side Egypt, and the most important ones include: Le Roy, 1953;Said &Kenawy, 1956;Barr, 1970;Saperson & Janal, 1980;Geroch & Nowak, 1983;Anan & Hewaidy, 1986;Hewaidy, 1987;Anan & Sharabi, 1988;Shahin, 1988;Berggren & Miller, 1989;Ismail, 1992;Fluegeman et al, 1990;El-Deeb & El-Gammal, 1994;Ayyad et al, 1997;El-Dawy, 2001;El Dawy & Hewaidy, 2002Khalil & Meshaly, 2004;and El-Gammal & Hamad, 2015. At Gebel Qabeliat section, the Upper Campanian-Lower Eocene (Ypresian) succession contains abundant well preserved benthonic foraminiferal species. The vertical distributions of the identified benthonic foraminiferal species are used in the classification of this time interval, at this studied section into seven benthonic foraminiferal zones.…”

“…This zone is equivalent to the Bolivinoides decoratus Zone of Shahin (1988) at Gabal Nezzazat; El Ashwah (1998) in the northwestern part of the Western Desert; Khalil & Meshaly (2004) at Gabal Musaba Salama, and El Ashwah (2000 & 2005& 2006) in the north Western Desert. Also, this zone may be equated with the Cibicides praecursorius Zone of Ayyad et al (1997)…”

Depositional facies, environments and sequence stratigraphic interpretation of the Middle Triassic–Lower Cretaceous (pre-Late Albian) succession in Arif El-Naga anticline, northeast Sinai, Egypt

“…No detailed synthesis on the sedimentology of the Arif El-Naga Middle Triassic-Lower Cretaceous deposits exists, although the lithological description of the succession has been presented by Thiebaud (1942), Awad (1946), Spath (1946), Eicher (1946Eicher ( , 1947, Zak (1957Zak ( , 1964, Haas (1959), Kummel (1960), Lerman (1960), Karcz and Zak (1968), Druckman (1974), Eicher and Mosher (1974), Bartov et al (1980), Parnes (1986), Allam and Khalil (1988), Kuss (1988), Abed et al (1996), Ayyad et al (1996Ayyad et al ( , 1997, El-Badry et al (1997), El-Sheikh (1997), Sobhy (1998), and Abu ElEnain and Morsi (1999). These workers tackled the stratigraphy, paleontology, structural setting of the area and to a certain extent the petrography and diagenesis of the Triassic sediments.…”
