Tectonics, Volume 44, Issue 10, October 2025.Abstract Inception of obduction is a rare phenomenon in the Wilson cycle and requires specific prerequisites to transfer relatively high‐density oceanic lithosphere over the less‐dense continental lithosphere. The world's famous Semail ophiolite belt developed during the Late Cretaceous, when Neo‐Tethyan oceanic lithosphere obducted onto the rifted ...
