The article presents a study on Ophiolites which represents fragments of the ancient oceanic lithosphere. Topics discussed include the importance of ophiolites in determining the mechanism of the tectonic plates, global tectonic evolution and reconstruction of the supercontinent, Metamafic-ultramafic rocks commonly occurring as lenses and metamafic–ultramafic complex and metasupracrustalrocks combined into an ophiolitic mélange suffered paleoproterozoic amphibolitegranulite facies metamorphism.
