| Abstract | ||
| The present work deals with the analysis and interpretation of airborne magnetic survey data of Wadi (W.) Abu-Had area, northern Eastern Desert of Egypt. This area is traversed by several wadis, mainly with NE and ENE directions, and comprises igneous and metamorphic rocks, with the exception of its eastern part, which is mainly covered by sedimentary rocks. Structural interpretation of the aeromagnetic data was achieved through the application of some advanced interpretation techniques that delineate the magnetic structures and estimate their depths. These techniques include second vertical derivative (SVD), analytic signal (AS) and Source Parameter Imaging (local wave number) (SPI). The interpreted magnetic structures reveal that the area is dissected by a set of faults trending mainly in the N-S, NNW, NW, NE and ENE directions. Moreover, the eastern part of the studied area, is occupied by a broad belt of low magnetic relief, which suggests a deep- rooted causative mass which indicates a deeping of the basement rocks. The estimated depths and dips using (SPI) method show that the eastern part is deeper than the other parts of the study area. The depths were found to range from 525m to 1605m and they are oriented in the NE, NNE, NNW and SW directions | ||
