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.
