Agnes high, Western Desert, Egypt: A structural study in view of potential data modelling

Results of the qualitative analysis show that Agnes high gravity and magnetic association is mainly caused by a near surface igneous intrusion of NW orientation. Quantitatively, regional models indicate a normal continental type of crust, which is divided into upper and lower by the Conrad surface (21.5-22 km). The crust-mantle interface lies at 32-33 km meanwhile the magnetic crust reaches a depth of 16 km. Local models reveal that the basement rocks north and south of the Agnes high were offset by some 6-8 km and 3-4.5 km, respectively. Statistically, the area was controlled by two main old trends; the most prevailing WNW to NNW (East African) and the less abundant ENE (Syrian Arc) trends. These two principal trends almost have its doubtless impact on preservation of possible accumulations.
