From 25 to 16 Ma, a series of basaltic, trachytic, and rhyolitic dikes were emplaced along the Red Sea margins [Zumbo et al., 1995], at the same time as emplacement of large granitic batholiths (Jabal Hufash and Jabal Bura, see Figure 2). These granites are oriented north-south [George et al. ...

In this respect an important question comes up, whether it is suitable to put together DSS and seismological data by associating the low Moho velocities ( ...
