Formation
Hyaloclastite is a type of Igneous rock is formed through the cooling and solidification of lava or magma.
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.
