Ophiolites are sections of the Earth’s oceanic crust and upper mantle that have been uplifted and exposed above sea level, typically as a result of tectonic processes such as obduction. These rock complexes provide valuable insights into the composition and structure of the oceanic crust, as well as the processes of seafloor spreading and subduction.
