In this paper we present and analyze spreading-parallel seismic transects that image the oceanic crust in eastern Gulf of Aden, from Oman to Socotra margins, across active Sheba mid-oceanic ridge between Socotra-Hadbeen Eastern Aden Fracture Zones. The correlation potential field data sets gravity modelling allow us document spreading history basin onset seafloor ∼16 Ma-ago present. Two main su...
