Interpretation of Aeromagnetic Data on the Area around Aswan-Berenice Road, Southeast Aswan, Egypt

Abstract

The area around Aswan-Berenice Road southeast Aswan is geophysically studied to delineate the subsurface structures and to evaluate the tectonic framework of the basement rocks and the overlying sedimentary cover. This area comprises a variety of igneous, metamorphic and sedimentary rocks, ranging in age from Precambrian to Quaternary time. The interpretation of the aeromagnetic data around Aswan-Berenice Road was carried out using GM-SYS modeling technique. Many methods were performed to the RTP aeromagnetic map of the study area such as filtering and trend analysis techniques. The tracing upward and downward of the deduced subsurface structures was investigated using trend analysis for the surface geology and filtered magnetic maps. The locating and determination of the approximate depth of the causative bodies were done using Euler deconvolution, Werner deconvolution and 2.5 dimension magnetic modeling techniques. The obtained results indicate that the most significant tectonic trends are N-S and E-W, which they are in accordance with the local trends of River Nile and Kalabsha fault respectively. Less common trends as NW-SE and NE-SW directions are also detected. Also, the depth to the basement rocks ranges from 0 km at the exposed parts to 1.4 km at the covered parts.
