USE OF AEROMAGNETIC DATA IN THE INTERPRETATION OF THE STRUCTURAL FRAMWORK OF EAST ASWAN AREA, SOUTHERN EASTERN DESERT, EGYPT

The delineation of gross structural framework of East Aswan area, located between latitudes 23° 45′ - 24° 07′N and longitudes 32° 55′ - 33° 24′ E southern Eastern Desert of Egypt, was reached through the integration of some interpretation techniques applied to the aeromagnetic survey data reduced to the pole (RTP). These techniques are power spectrum technique, regional-residual separation, upward continuation, second vertical derivative and analytical signal. The results obtained from the various interpretation techniques were used in an integrated manner to construct the interpreted magnetic basement structural map. The structural elements affecting the study area include faults and folds (down faulted and uplifted block). Trend analysis techniques were applied on the resultant structural elements, to define the significant and predominant tectonic trends affecting on the study area, that are responsible for the structural development of its geological units. As a result of the application of the rose diagram for the main trends proved to be significant. Those trends are sorted from the strongest to the weakest as NW, NE, WNW and NNE.
