What are the main geological features of Oman?
Geological stories can be found just about anywhere, from Oman’s highest mountain, Jebel Shams, to the mega-dunes of the Empty Quarter (Rub Al Khali) and the Rock Garden at Duqm. The Sultanate of Oman is the only country in the world composed mostly of oceanic crust and rocks that originate from the Earth’s mantle.
How the geological features of Oman were formed?
The Oman ophiolite likely formed when oceanic crust was thrust atop the Arabian continental crust as that buoyant material encountered the subduction zone and halted subduction. Today, the ophiolite has eroded and the deep rocks beneath it are exposed through a tectonic window in the Hajar Mountains.
Why is the geology of Oman unique?
The Oman Mountains have a unique belt of high-pressure eclogite, blueschist and carpholite-grade metamorphic rocks in northeastern Oman, a zone associated with attempted subduction of the leading margin of Arabian crust beneath the Semail Ophiolite–Gulf of Oman oceanic crust.

What are the blue rocks in Oman?
Blueschists are rocks formed by regional metamorphism in subduction zones, meaning its protolith (parent rock or the original, un-metamorphosed rock), likely a sea floor basalt, was metamorphosed due to heat and pressure affecting rocks over an extensive area accompanied by deformation under differential stress …
