Structure and morphology of the Red Sea, from the mid-ocean ridge to the ocean-continent boundary

The diversity and complexity of existing models on the structure Red Sea is result a mobile sedimentary cover that not only hides most basement oceanic structures but also hamper geophysical signals. In this study, we combined published with new unpublished data to propose revised interpretation lithosphere between Hanish Islands (ca. 13.5°N) Dead Fracture Zone 27.5°N). recognition allochthonous salt overburden allows structural model simple geometries are consistent present-day kinematic constraints (GPS velocities Euler Poles) rules plate's motion sphere (Euler Theorem). We mapped continuous Mid Ocean Ridge segment parallel main rift orientation in southern becomes highly discontinuous more oblique towards north as it gets closer Pole. These segments all point pole consistently offset right by transform faults central northern cumulating an 400 km. accommodating seafloor spreading cluster three fracture zones: (1) Ikwan near (or Brother) Islands, (2) Zabargad vicinity Island (3) Jeddah offshore Jeddah/Port Sudan area (central Sea). Based seismic reflection dataset Continent Transition (OCT) Sea. bring evidence (magnetic lineaments, distance OCT ridge, basin stratigraphy) support Middle Miocene 14 Ma) age for initiation throughout Sea, discuss event strike-slip Aqaba-Dead zone. Finally, compiling available literature, regionally coherent geodynamic reconstruction using two different poles rotation rifting phases.
