Sequences of deep-sea sediments, oceanic crust, and upper mantle rocks on land-called ophiolites-indicate the presence of an old convergent boundary.

Question

Quizplus · Accepted Answer

Ophiolites are commonly associated with convergent boundaries, where one tectonic plate is forced underneath another. The sequence of rocks found in ophiolites corresponds to the oceanic lithosphere, including deep-sea sediments, basaltic crust, and mantle peridotite.
