MetadataShow full item record
This paper deals with the study of planktonic foraminifera, larger foraminifera and ostracoda in the Oligocene sediments in four wells: Abu Tunis No. IX, East Faghur-I, Khalda No. I and North Ghazalat No. I, North Western Desert. It was possible to recognize the following foraminiferal biozones, which are from top to base: Miogypsinoides complanatuslLepidocyclina spp. Zone = Nummulites aff. bouillei Zone and Globorotalia opima opima Zone of Chattian Age and Globigerina ampliapertura Zone and Cassigerinella chipolensis Zone of Rupelian Age. The topmost zone correlates well with that described from Tunis by Biely and Kohler (1976).
