Tectonic setting, origin, and obduction of the Oman ophiolite

Abstract:

The Semail ophiolite in the Oman Mountains is the world's largest and best preserved thrust sheet of oceanic crust and upper mantle (>10 000 km2, ~550 km long, ~150 km wide); it was emplaced onto the Arabian continental margin during Late Cretaceous time. The ophiolite originated 96-94 Ma at a spreading center above a northeast-dipping subduction zone associated with initiation of immature island-arc tholeiitic lavas (Lasail arc) at the highest levels of the ophiolite. Simultaneous underth...
