Aeromagnetic Lineaments delineation in the Northern part of Central Eastern Desert, Egypt
Abdellatif, M., Elkhateeb, S.
The total intensity aeromagnetic map of Northern part of Central Eastern Desert, Egypt was subjected to study and analysis utilizing various processing techniques such as reduction to pole, horizontal gradient magnitude, and tilt derivative in order to outline the geological set-up and the structural features affecting the basement complex and overlying sedimentary cover. The results indicated that the eastern part of the study area was highly faulted more than the western part. The predominant tectonic trends are NW-SE, NE-SW, NNE- SSW, ENE-SWS, NNW-SSE, N-S and W-E directions respectively arranged according to the degree of their importance. The most developed one among these trends is the NW-SE (Gulf of Suez or Red Sea trend) which has a vital importance in the tectonic setting of the study area more than the other ones. On the other hand, the Euler Deconvolution with structural index (SI) = 0.0 and 2-D modeling techniques were carried out to estimate depths of the causative sources which help in establishing the structural set up of the study area. The obtained mean depth values to the causative sources using both methods reach about 3 km. The deepest causative sources observed in the western part of the study area are associated with a sedimentary cover while the basement rocks reveal the shallow sources in the eastern part.
