| Abstract | ||||
| The available remote sensing (RS) and aeromagnetic data were integrated to derive the structural lineaments, both on the surface and in the subsurface, and to determine the locations and depths of causative magnetic bodies, to understand the structures controlling them at Gabal Umm Tinassib and its surrounding area, located in the Egyptian Northern Eastern Desert. RS data underwent several processing steps to illustrate the main directions of surface lineaments. Various techniques were employed on the aeromagnetic data, including radially averaged power spectrum, high and low-pass, upward continuation filters, analytic signal (AS), source parameter imaging (SPI), and Euler, tilt derivative (TDR), and horizontal gradient magnitude (HGM). The structural lineaments were identified from the RS maps, they trend in the NE-SW, NW-SSE, and E-W directions, with minor indications in the N-S direction and various others. The power spectrum technique was utilized to get two major average magnetic interfaces at depths of 790 m and 2200 m, which aided in the creation of residual and regional aeromagnetic maps. Depth estimates for the tops of causative magnetic bodies were obtained using three different techniques, revealing depth solutions ranging from -3 to -2291 m for AS, -154 m to -2421 m for SPI, and -1 m to -2192 m for Euler. Significant structural lineaments were extracted from various filtered aeromagnetic maps, organized according to magnitude and importance, showing trends in the NW-SE, NE-SW, NNW-SSE, and NNE-SSW directions, with minor trends in the N-S and E-W directions. | ||||
