“…Also, it is equivalent to the Rugoglobigerina hexacamerata (CF8b) Zone of Li et al, 1999. In Egypt, this biozone may be correlated with the upper part of Globotruncana fornicata Zone of El-Naggar, 1966; the upper part of Globotruncana tricarinata of Shahin, 1988; the upper part of Globotruncana falsostuarti Zone of Luning et al, 1998; the upper part of Globotruncana aegyptiaca-Globotruncanita stuartiformis of El Dawy et al, 1992; the upper part of Globotruncana aegyptiaca of Cherif & Ismail, 1991, Shahin, 1992, El-Nady, 1995Ayyad et al, 1996;and Shahin & El-Nady, 2001. The most important planktonic foraminiferal species recorded from this biozone are: Heterohelix globulosa (Ehrenberg), Heterohelix aegyptiaca Ansary & Tewfik, Planoglobulina glabrata (Cushman), Pseudotextularia elegans (Rzehak), Pseudoguembelina costulata (Cushman), Globotruncana aegyptiaca Nakkady, Globotruncana ventricosa White, linneiana (d'Orbigny), Globotruncanita conica (White), Globotruncanita stuartiformis (Dalbiez), Globotruncanita stuarti (De Lapparent), Globotruncanita subspinosa (Pessagno), Globotruncanita pettersi (Gandolfi), Globotruncanella citae Bolli, Rugotruncana subcircumnodifer (Gandolfi), Rugotruncana subpennyi (Gandolfi), Rugoglobigerina macrocephala Bronnimann, Rugoglobigerina rugosa (Plummer), Rugoglobigerina hexacamerata Bronnimann, and Rugoglobigerina scotti Bronnimann.…”

“…A lot of papers were published on the planktonic foraminiferal biostratigraphic classification of the Upper Campanian -Lower Eocene (Ypresian) successions inside /outside Egypt and the most important of these include: (Bolli, 1957aEL-Naggar, 1966;Fahmy et al, 1969;Beckmann et al, 1969;Youssef & Abd ElMalik, 1969;Blow, 1979;Berggren, 1969;Postuma, 1971;Barr, 1972;Premoli Silva & Bolli, 1973;Berggren & Van Couvering, 1974;Stainforth et al, 1975;Abd ElMalik et al,1978;Benjamini, 1980;Masters, 1984;Robaszynski et al, 1984;Boersma, 1984a;Caron, 1985;Toumarkine & Luterbacher, 1985;Bolli et al, 1985;Al-Mogi-Labin et al,1986;Hewaidy, 1987;Berggren & Miller, 1988;Huber, 1990;Shahin, 1988Haggag, 1991;Cherif & Ismail, 1991;El-Dawy et al,1992;Hewaidy & Soliman, 1993;Berggren et al, 1995;Abd el-Kireem & Samir, 1995;El-Nady, 1995;Keller et al, 1995;Ayyad et al, 1996;Aubry 1996;Berggren & Norris, 1997;Li & Keller, 1998a,b;Marzouk & Luning, 1998;Aubry et al, 1996Aubry et al, , 1999Luning et al,1998;…”

“…Robaszynski et al, 1984 andCaron, 1985); while according to Li et al, 1999, this biozone belonged to the Late Campanian. In the study area, this biozone is equivalent to the lower part of Globotruncana lapparenti tricarinata Zone of Bolli, 1966; the lower part of Globotruncanita stuartiformis Zone of Postuma, 1971; the lower part of Globotruncana tricarinata Zone of Barr, 1972; the lower part of Globotruncana falsostuarti Zone of Robaszynski et al, 1984;Al-Mogi-Labin et al, 1986; the Globotruncanella havanensis Zone of Caron, 1985; and the Globotruncanella subcarinatus (CF9) Zone of Li & Killer, 1998a & b;and Li et al, 1999.

Isotopic, Geophysical, and Hydrogeochemical Investigations of Groundwater in West Middle Upper Egypt

“…Land reclamation extends in the area from the Eocene limestone plateau in the west and the recent Nile deposits in the east. Various lithostratigraphic studies have been conducted by many authors. − Quaternary (mainly of Plio-Pleistocene) sediments are found at the foot of the scarps along the Nile’s banks on both sides. The majority of Assiut is covered with recent to subrecent alluvial deposits on both sides of the Nile’s banks.…”
