Greiling Eds. pag 345-369 TITLE = Some Geophysical Aspects of the Evolution and Structure of the Crust in Egypt In 1980 the General Petroleum Company (GPC), Cairo, Egypt, published a set of Bouguer maps of Egypt on a 1:500,000 scale by compiling all available gravity data. This is a two dimensional density model showing the crustal thickness and geometry along the Western Desert. The model is seismically constrained from 10 deep seismic sounding profiles performed in 1978 and 1981 by the Intitute of Geophysics, University of Hamburg, and the Helwan Institute of Astronomy and Geophysics. Details about the seismic data are not available in this publication.
