Abstract

The purpose of this study is to define the geographic area of an estimated depth to an Eastern desert intrusion near wadi Qena. The study also clarified the many stages of deformations connected to this intrusion. Aeromagnetic data was employed using the goal of this investigation for this purpose. Along with the underlying structure, these intrusions' depths and magnetic susceptibilities were evaluated. To get RTP magnetic data with anomalies concentrated on the subsurface causal bodies, the magnetic data was reduced to the North Pole. Various filtering methods were used. The power spectrum approach was used to determine the distance to the causative bodies. The maps reveal significant magnetic anomalies caused by basaltic intrusion inside sedimentary strata with a general NNW-SSE trend and very probable multi-phase intrusion activity. Calcite crystals were seen in a few of the measured joints. Various techniques are used to determine the major depth to the causative bodies.
