Stratigraphy And Petrology Of The Eocene Rocks At Maghagha (East And West), Nile Valley, Egypt

Abstract

Combined paleontological and petrological studies on the Eocene rocks at Maghagha revealed that the succession belongs to one biostratigraphic zone; the Numrnulites gizehensis gizehensis zone. Nummulites striatus was recorded in this zone. This implies that the range of N. striatus should be lowered to the dawn of the middle Middle Eocene. The nature of the faunal content of the succession together with its lithological characteristics suggests deposition in a quiet shallow marine environment.
