英文摘要 | The study area lies to the east of Qattara Depression at the north of the Western Desert, Egypt. It is bounded by latitudes 29A degrees 00’ and 30A degrees 00’ N and longitudes 28A degrees 00’ and 29A degrees 30’ E, including Abu Gharadig basin, which is the most petroliferous basin in the Egyptian Western Desert. Numerous exploratory wells show that the area is characterized by a thick sedimentary section, unconformably overlying the basement rocks. The main objective of the present study is to outline the structural parameters controlling the area under consideration. Aeromagnetic and gravity data were subjected to the analytic signal, 3D Euler deconvolution and edge enhancement techniques. The Analytic signal and 3D Euler deconvolution were utilized mainly to locate the main subsurface contact zones and to determine the depth and structural indices of the expected causative subsurface structural elements. However, the edge enhancement technique was used with various windows to enhance the edges of subsurface structures. The structural indices were estimated to be ranging between 0.16 and 0.26, indicating that the area is mainly controlled by faults. The depth of these structural elements was also estimated to be ranging between < 1.37 and 5.29 km. It has been shown that the structural elements of the study area have different directions, trending E-W, ENE, NW, and N-S. |
