Ophiolithes are according to Wikipedia a section of the Earth's oceanic crust while the underlying upper mantle has been uplifted and exposed above sea level and emplaced onto continental crustal rocks. Ophio is Greek for snake, and lite (from Greek lithos) means stone, after the green-color rocks that make up many ophiolites. Their great significance relates to their occurrence within mountain belts such as the Alps and the Himalayas, where they document the existence of former ocean basins that have now been consumed by subduction.
