WebFirst, because a large portion of dense material is removed, the remaining portion of the crust and lithosphere undergo rapid uplift to form mountain ranges. Second, flow of hot mantle material encounters the base of the thin lithosphere and often results in melting and a new phase of volcanism. Web27 sep. 2016 · The evolution of the theory of plate tectonics is one of the recent major discoveries by scientists. According to the theory, the earth’s crust or the outer layer is made up of a series of plates consisting of lithospheric material that floats over the denser asthenosphere on the upper mantle across the Earth’s interior.

Plume-driven recratonization of deep continental lithospheric mantle
