Question

Quizplus · Accepted Answer

Ophiolites are sections of the oceanic crust and the underlying upper mantle that have been uplifted and exposed above sea level and often emplaced onto continental crustal rocks. An ophiolite suite typically includes, from bottom to top, ultramafic rocks from the mantle, gabbros, basaltic dikes, and pillow lavas, often capped by deep-sea sediments. Granitic plutons are not typically part of an ophiolite suite because they are associated with continental crust rather than oceanic crust.
