Description :
Here, the AA. present new apatite fission-track (AFT) data from Sudan northern hinterland and Red Sea coastal areas. These data prompted a review and comparison with low-temperature thermochronological data from the whole Nubian Red Sea Margin, and a discussion on their implication in assessing the margin evolutionary style. As to the mode of margin evolution, AFT age patterns both in Egypt and Eritrea are incompatible with a downwarp model. The distribution of apatite (U-Th)/He (AHe) ages across the Eritrean coastal plain suggests that there the escarpment was evolving predominantly by plateau degradation.
