DELINEATING SUBSURFACE GEOMETRY AND STRUCTURAL FRAMEWORK OF WADI EL-ASSIUTI BASIN USING AIRBORNE MAGNETIC DATA MODELLING, EASTERN DESERT, EGYPT

Wadi El-Assiuti is considered as one of the most substantial basins in the Eastern Desert (ED) of
Egypt. It occupies a large area at the eastern bank of the River Nile, close to Assiut city. It can be considered as the
natural and fundamental extension for the ongoing development and agricultural reclamation processes at this part of
the Eastern Desert of Egypt. From this point, the necessity to delineate the factors affecting the perspective shape and
structural framework of the area using one of the famous geophysical prospecting tools becomes a first priority for
decision makers. The present study deals with the aeromagnetic survey that was executed over the study area as a part
of the Eastern Desert of Egypt. Qualitative as well as quantitative interpretation of the aeromagnetic data were carried
out to obtain more information about the crystalline basement structure and the depth to its surface.
Results define that the surface of basement rocks occur between 930 m to 2560 m below sea level and the average
thickness of the sedimentary cover reaches to about 2186 m. The regional structure lineaments revealed from the
derived magnetic maps have directions nearly NE-SW, NW-SE and E-W directions
