Abstract

Prom the previous study, the following conclusions can be derived:- 1. The major tectonic trends in the studied area are the following, arranged in decreasing order of magnitude : - a) NNW-SSE (B 35Ow) which is the Suez trend. b) ENE-WSW (B 60•‹-70•‹E), which is the gyrian Arc trend, c) IBNE-SSW (I? 35. E) , which is the Aqaba trend. d) H-S trend, which is the East Africian R i f t trend. e) E-YY trend, which is the Tethyan trend, and considered to be the oldest one, 2. Reddual magnetic maps reflect the Miocene and younger basement tectanica of IW trend (Suez) and IQNE trend (Aqaba) . 3. The residual magnetic maps produced by applying Griffin’s method (E=4) and the Nine-Points (E=5) were the best to map the residual NW trending structures. 4. Regional magnetic mags reflect the Pre-Miocene older I structures of EBlE trend (Syrian arc) as Wadi Araba structure, 5. The basement tectonic map &OWE that the basement rocks in the studied area, as composed of tilted fault blocks of BW trend, that are separated by half-grabens of the same trend. 6. The basement tectonic map shows the discontinuity of the MYY-trending basement blocks along their extension, along a set of NE trending transcurrent faults of both right and left-lateral translational motion. 7, The age of these NE transcurrent faults is considered to be of bliocene age since they represent the complementary shear fracture of the ’w-system of faults in the Gulf of Suez region. 8. NE trending faults of vertical throw are considered to be of Pre-Miocene age, most probably asaociated with the Syrian arc system of Cretaceous age, 9. Some basement blocks dip to the SW while othera dip to the NE direction. 10. The basement rocks of the on-ahore part of the studied area is shallower than that in the off-shore part of the studied ares. 11. Among the depth methods used within this study, Smellie’s sethod , (1956)’ . gave the best depth estimate among other methods, since it correlated better with depth resu1.t;o~b tained from quantitative modeling. , 12. Magnetic method is an excellent tool for delineating and quantffging basement configuration. Ln thie regard the following techniques can be appliedt magnetic trend analysis, depth determination Oeohniques, isolation of magnetic anomalies and quantitative modeling along selected prof ilea across the studiea area. 13. In order to obtain better modeling resulte all geophysical and geological informations about the studied area should be included within the modeled data. 14. The basement rocks in the studied area seem to be intersected by reversly-polerized rnagnetised dykes. This conclusion was enhanced by quantitative modeling along p r o f i l e B.Bv.
