5 Formation
5.1 Formation
Peridotites can be formed in two ways: as mantle rocks formed during the accretion and differentiation of the Earth or as cumulate rocks formed by precipitation of olivine and pyroxenes from basaltic magmas.
Gabbro, a mafic rock, forms due to cooling and crystallization of magma underneath Earth's surface.
