A standardized logging sheet was developed and used to log the studied sections

of the Cairo-Suez District, Egypt. The main properties recorded in these sections are:

texture, biota, grain type and size, sorting, bedding style, sedimentary features of the

rocks and facies. 450 representative samples were collected from the field to produce

162 thin sections, which were examined under polarizing microscope to integrate

lithological, paleontological and diagenetic data for facies characterization, 74 and

sequence stratigraphy. The nomenclature of limestone in the present study follows that system introduced by Dunham (1962) and Embry and Klovan (1972).
