The earth’s mantle consists predominantly of ultramafic rocks. The mantle is, with the exception of some small anomalous regions, in a solid state. The ultramafic rocks undergo continuous recrystallization due to large-scale convection in the sublithosphere mantle and as a result of tectonic processes in the lithosphere. The bulk of the mantle rocks, therefore, meet the criteria of metamorphic rocks. Metamorphic ultramafic rocks represent the largest volume of rocks of the planet.
