Abstract
The present study deals with the sedimentology and biostratigraphy of the lower Paleogene successions in the Kharga and Dakhla oases, Western Desert, Egypt. The uppermost part of the Cretaceous is also considered in this study. A total of 226 rock samples were collected from the three stratigraphic sections at Gabal Ghanima, Gabal Teir/Tarawan (Kharga Oasis) and Gabal El Qasr (Dakhla Oasis). Mineralogical and petrographical analyses were carried out for interpretation of provenance and depositional environments. Meanwhile, the planktonic foraminiferal and calcareous nannofossil contents have been utilized for biostratigraphic purposes, age dating, paleoclimatic and paleoenvionmental interpretations. Lithostratigraphically, the upper Maastrichtian-lower Eocene success ions along the studied sections are differentiated into four rock units of wide distribution. These units are arranged from base to top into: the Dakhla Formation late Maastrichtian to late Paleocene), Tarawan Formation (late Paleocene), Esna ormation (late Paleocene to early Eocene), and Thebes Formation (early Eocene).
