Formation
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.
Flint is formed by the decomposition and compaction of various organisms such as sponges and diatoms under the water.
