Abstract

The basin of Gilf Kebir is located in the southwest region of the Western Desert of Egypt. The lithologies and geological structures in the area indicates that it has the perfect formation system of Paleozoic intra-cratonic rift. This study analysed and integrated the interpretation of remote sensing (Landsat 9), geophysical (aeromagnetic and satellite gravity data), and geological data to understand the underlying structure of the area of Gilf Kebir Basin.
Basins of the Paleozoic intracratonic formed within the African Shield subsequent to the deformation and plutonism of Precambrian. A thick clastic Gilf sandstone was deposited between the two major plutons of the Uweinat area in the west and the Tarfawi area in the east.
Landsat 9 data were analyzed to map surface geological units, delineate the structural framework of the Gilf Kebir Basin, and map the distribution of lithologies. The dominant structural tendencies are NE-SW/ENE-WSW, sub-E-W, and NW-SE/NNW-SSE. The depths in the basin were determined using a three-dimensional (3D) depth inversion. The results show that the thickness of the sedimentary section ranges from zero (basement outcrop) to more than 3000 meters.
