Analysis and interpretation of aeromagnetic data for Wadi Zeidun area, Central Eastern Desert, Egypt

The current study is mainly concerned with the analysis and interpretation of the available aeromagnetic data using different advanced processing techniques, to map the subsurface structural framework and depth estimation of these structures of the Wadi Zeidun area, Central Eastern Desert. The visual inspection of the RTP aeromagnetic map defines a rapid change in the subsurface geologic conditions in the form of the lithological characters and tectonic inferences. The shallow sources can be separated from those of deeper causatives, using power spectrum transformation tool. Two methods for locating magnetic sources, Source Parameter Image and Analytical Signal to identifying the properties of their sources indicated that, the depth calculation from the used tools ranges between 900 and 3000 m as the average ranges. Also, the comparative study among the 2D magnetic modelling was established by two profiles constructing. The mapped basement tectonic map is affected by a set of faults trending mainly in the N-S, NE-SW, NW-SE and ENE-WSW direction.
