1.1 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.
Mylonites are ductilely deformed rocks formed by the accumulation of large shear strain, in ductile fault zones.
