5 Formation

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.

The formation of Appinite takes place deep beneath the Earth’s surface at around 150 to 450 kms, and are erupted rapidly and violently.

Peridotite vs Appinite 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 Appinite Reserves. Peridotite is a dense, coarse-grained plutonic is the main constituent of the earth's mantle. Appinite is an igneous rock in which the crystals are so fine grained that individual minerals cannot be easily distinguished. 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 Appinite information and Peridotite vs Appinite characteristics in the upcoming sections.
