Serpentinization reactions produce highly reduced waters that have hyperalkaline pH and can high concentrations of H 2 CH 4 . Putatively autotrophic methanogenic archaea been identified in the subsurface Samail Ophiolite, Sultanate Oman, though strategies to overcome dissolved inorganic carbon limitation remain be fully understood. Here, we recovered metagenome assembled genomes (MAGs) applied ...

A common deviation from typical subduction models occurs when thrust sheets of oceanic crust and upper-mantle rocks are emplaced over more buoyant continental lithosphere. The archetypal example ophiolite obduction is the Semail in United Arab Emirates (UAE)-Oman orogenic belt, formed obducted onto Arabian margin during Late Cretaceous. Strait Hormuz syntaxis, northern extent UAE-Oman mountains...
