 (ŏf′ē-ə-līt′, ō′fē-)
Any of a group of rocks, especially mafic and ultramafic igneous rocks, thought to have formed during crustal thinning at a mid-ocean ridge and to have been subsequently thrust onto continental crust.

[French ophiolite : Greek ophis, snake (in reference to the typically greenish serpentine rocks, diabase, and peridotite found in ophiolites) + French -lite, -lite; see -lite.]

To understand these systems in the deep geological past it is necessary to work on ancient examples of detachment faults in ophiolites, slices of oceanic lithosphere that have been emplaced tectonically onto continental margins and which expose ocean floor structures in 3-D.

To discuss future scientific cooperation, Professor Cloetingh has been invited by the AGEO department and the Department of Geosciences of RWTH chen University, who have also organised a one week field trip around the north of Oman including a large number of sites of geological interest, such as the exposed crust/mantle transition and the ophiolites in Wadi Al Abbyad, carbonate sequences and source rocks and the uplifted coastal terraces along the Omani coastline, an area that is currently part of a tsunami research project conducted by Prof.
Springs also constitute a surface water resource, with the majority being located in mountainous areas, discharging their water from two major geological formation -- Al Hajar limestones and the ophiolites.
