ABSTRACT
This chapter discusses the main stratigraphical divisions of time and biostratigraphic units based on foraminifera. These are compiled in a correlative scheme for the practical use of the oil and other related industries. The scheme is based on many years of applied work in oil exploration and on the results of a large number of published and unpublished works. Eighty-seven zones are introduced based on both the planktonic and benthonic foraminifera. Some of these zones, especially those based on the planktonic foraminifera, are of worldwide distribution but many others are of local application to Egypt. Numerous attempts were made in the past to zone different parts of the stratigraphic column by the use of foraminifera. Of these, special mention is made of the pioneering work of Beckman et al. Other valuable publications can be found in the bibliography under Abdel Sattar, Andrawis, Ansary, El Heiny, Kenawy, Nakkady, Omara, Said, Souaya, Wasfy and others.
