## 6 Conclusions  
1. In general, the considered models revealed that the southeastern portion is oceanic crust, which is exposed by approximately 13-km thick sediments.
2. The transition from continental to oceanic crust was also observed at approximately 56 km from the Arabian Plate, with the continental crust mainly found beneath the Eratosthenes Seamount.
3. The gravity model was used to assess the density disseminations of the deep lithospheric structures along the northern Egyptian passive continental margin.
4. The marine gravity data investigation revealed the bathymetry features of the oceanic crust and the intra crustal homogeneities within it. An examination of the gravity

data was carried out to develop the geometry and the density spreading in the 2D designed profiles. (5) The results of this study provide a significant contribution to knowledge on the inferred landscape and proper crustal structure of the northern Egyptian passive continental margin. (6) The 2D modelling of gravity was adapted so that the calculated gravity anomalies were adjacent to those detected without any substantial variations of the seismic achieved geometry. The synthesis of the analysis and results leads to the following conclusions: - There is a transition from the continental to oceanic crust at the Levant Basin about 56 km from Arabian Plate and about 40 km from the Egyptian coast. - The modelled and observed gravity field showed good agreement, including known regional structures. - The model has shown evidence on the crustal structure caused by the severe tectonic activities and the great thickness of sedimentary layers, which cover the crystal line crust. - The 2D gravity modelling results fit into the existing geodynamic and tectonic framework. - Finally, more advanced geological and geophysical studies are important for present assembly projects to identify recent tectonic movements inside the area under investigation.
