PHYSICAL AND MECHANICAL PROPERTIES OF THE CRETACEOUS LIMESTONE, PYRAMIDS HEIGHTS, EL-HASANA DOME, EGYPT.

Abstract

Pyramids Height lies about 16 km west to Cairo and nearby El-Hassana dome about 2 km to the south, and located at 30°0’38.17” N and 31°4’7.42” E. The main objective of this study is to evaluate the physical and mechanical properties of carbonate Turonian rocks and their behaviors. Core data from ten boreholes have been processed through a sequence of graphical and computational relations to delineate and evaluate quantitatively the different physical and mechanical parameters. The results have been illustrated through a graphical relationships between different parameters showing the graphical variations of the carbonate rocks properties. While thin sections facilitated in setting deeper understanding of the carbonate Turonian characteristics and the different factors affecting them especially the fracturing role and the nature of deposition. This thesis begins by outlining the introduction and proposes for study physical and mechanical properties of carbonate rocks according to engineering propose and study rock characterization, recognize the previous works for the study area. In chapter 2, representing the location for study area and locations for borehole wells. Investigating along the geologic setting, lithology, structure and stratigraphy. Scope about cretaceous rocks especially for Turonian rocks the major study, clarifying the main faults and folds in El-Hassana dome. Ended with petrographical study by thin sections scoping for Allochems and Orthochems for describing the lithological samples and also detecting pore spaces and fractures appearance.
