Samail Ophiolite

[3] Formed during the Late Cretaceous period, approximately 95 million years ago,[4] the Samail Ophiolite represents a fragment of the Tethyan Oceanic crust that was thrust over continental crust due to the convergence of the African and Eurasian tectonic plates.

This includes layers from the Earth's upper mantle, along with cumulate rocks, gabbros, sheeted dike complexes, and volcanic sequences, providing a vertical profile of oceanic lithosphere.

[5] The Arabian continental margin formed in the early Paleozoic and possibly the late Proterozoic.

[6] From the Sumeini group to the Haybi Complex make up the continental slope with an age range from Middle Triassic to Late Cretaceous.

The Wadi Tayyin is located in southwestern Oman near the classic Green Pool locality.
