Delineation of subsurface structural trends and depth of basement of Kattaniya inversion north western desert, Egypt: aeromagnetic data

Journal of Multidisciplinary Sciences (e-ISSN: 2671-5449), 2022

The area under investigation is located in the northeastern Western Desert and northwest Beni-Suef, covering Kattaniya inversion, Gindi basin, El-Fayum depression, and Wadi Al-Rayan area. It is extended to the east of the River Nile and bounded by Latitudes 29° N and 30° 30` N and Longitudes 29° 15` E and 31° 30` E. This study aims to delineate the subsurface structures and determine the depth of the basement complex in the area under investigation. The conversion of total intensity aeromagnetic data reduced to pole (RTP) magnetic intensity is the first step in achieving these objectives. Subsequently, multiple transformation methods and various filtering operations are applied to magnetic data through descriptive and analytical evaluations. Two methods have been applied on RTP aeromagnetic data to estimate the depth of basement and subsurface structure elements, the first method is power spectrum analysis, and the second method is 2D modeling. The (RTP) magnetic data have been spectrally split into regional and residual magnetic components by applying the estimated power spectrum technique. The average depths of both shallow and deep sources derived from the power spectrum are 3.5 km and 1.17 km. The study area's trends and structural styles are NE-SW, E-W, N-S, NW-SE, and ENE trends.
