Maastrichtian to Paleocene facies evolution and Cretaceous/Tertiary boundary in Middle and Southern Egypt

Abstract

The sedimentary history and facies development of southern Egypt during the Latest Cretaceous and Early Paleogene is summarized. The G. eugubina Zone is reported for the first time from middle Egypt, where the conglomerate usually marking a disconformity at the Cretaceous/Tertiary boundary, is absent. The Uppermost Maastrichtian strata are attributed to the M. prinsii Zone, the Late Maastrichtian index foraminifer Abathomphalus mayaroensis (Bolli) was not recovered in the investigated samples.
