We applied 2D integrated geophysical modelling for the determination of the lithospheric structure and<br />

its thickness in the Red Sea area. The results show large differences between continental and oceanic<br />

lithospheric structure and thickness. The oceanic crust of the Red Sea is much thinner (12-15 km) in<br />

comparison with the continental crust which is located on both sides of the Red Sea, and reaches the<br />

thickness of around 28-33 km. The density of the lowermost part of the upper mantle in the Red Sea<br />

area is very low indicating possible presence of partial melting in the upper mantle and supporting the<br />

theory of uplift of the asthenospheric masses in the Red Sea that is accompanied by the process of<br />

underplating beneath the Moho discontinuity.<br />
