Early Late Miocene Riftdrift transition in central Gulf of Aden. Miocene Pliocene transition Riftdrift transition in south-central Red Sea, jump of spreading west of 45E in Gulf of Aden (perhaps 3 Ma), and acceleration of AqabaLevant movement.

  20. 20. -3936 Middle East Geology -Geol 501-142 Conclusion The Gulf of Aden and the Red Sea rifting were initiated in Late Oligocene, ~25 Ma. The Triple Junction lying above the Afar Hot Spot is RRR type. AP11 lasted 34 Ma is defined as the package of sediments lying between the unconformity marking both the onset of Red Sea rifting and the first continent-continent collision, Zagros collision. Several tectonic phases are defined that fall into the categories of pre-rift, syn-rift, and post-rift. The Red Sea current reservoirs are : Jabal Kibrit, Umm luj mbr, Wadi Waqb mbr, and Burqan formation. AlWajh formation is considered as a prospective reservoir. The Midyan region provides a unique view of the Red Sea subsurface stratigraphy of Saudi Arabia.
