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.

Scoria forms when magma containing huge amount of dissolved gas flows from a volcano during an eruption.
