5.1 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.

Gabbro, a mafic rock, forms due to cooling and crystallization of magma underneath Earth's surface.

Peridotite vs Gabbro Information

Earth’s outer layer is covered by rocks and these rocks have different physical and chemical properties. As two rocks are not same, it’s fun to compare them. You can also know more about Peridotite and Gabbro Reserves. Peridotite is a dense, coarse-grained plutonic is the main constituent of the earth's mantle. Gabbro is an intrusive igneous rock which is chemically equivalent to plutonic Basalt. These rocks are composed of many distinct minerals. The process of formation of rocks is different for various rocks. Rocks are quarried from many years for various purposes. You can check out Peridotite vs Gabbro information and Peridotite vs Gabbro characteristics in the upcoming sections.
