Objective An integrated Land-Sea study of conjugate margins of the Gulf of Aden. Structure and segmentation, inherited structural features and reactivation, oblique secular aspect, timetable of Gulf opening, tectonic control of sedimentation, the Continent-Ocean transition, relations and processes of segmentation of the margin and the ocean lithosphere. Sheba ridge: segmentation, magmatism, obliqueness of the ridge. The related project is Salalah (Sultanate of Oman) - Reunion Island.
