Abstract
The northern Western Desert of Egypt is characterized by hydrocarbon potentialities and many oil and gas fields (producing from different horizons), of which the Abu Gharadig is very important. This work is mainly devoted to study the evolution of the Abu Gharadig basin and its surrounding areas using all available data, whether gravimetric (Bouguer anomaly map), geologic (drill hole information’s) or published material related to the geology of the area examined. The study area lies in the northern part of the Western Desert of Egypt between latitudes 280 OO’N and 30°30’ N, and longitudes 26°00’( and 31°18’). On the surface the area is covered by cretaceous, Tertiary and Quaternary sediments which show, in its greater part, gentle dips toward the north and northwest.
Depending on the available data the following maps, sections and diagrams were constructed in order to help in discussing the whole history of the area:
1. Isopach and lithofacies maps of Paleozoic to Late Eocene which elaborated, in many aspects, the previously known published maps.
2. Tectonic map of interpreted fault systems and shears to understand the geodynamic evolution of this part of northern Egypt. This map shows additions to the previously known fault trends given by previous authors. Models for the stresses which caused these fractures are also given in relation to the plate tectonic history of the area.
3. Four new geologic cross-sections expressing the vertical sedimentary development of the area through the different geologic times.
4. Three new hypothetical models of the depocenter of the Abu Gharadig basin, assuming three cases of maximum and minimum density contrasts (p and p ) according to Agarwal’s method max (l971b). These were achieved through a computer program in the Computer Centre of Assiut University.
5. A series of new pale geologic maps for the different ages, from Paleozoic to late Eocene, to detect the geologic history of the area.
