5 Formation

5.1 Formation

Laterite is a type of sedimentary rock which is generally a reddish weathering product of basalt.

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.
