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.

Eclogite forms from high-pressure metamorphism of mafic igneous rocks mainly, basalt or gabbro as it plunges into the mantle in a subduction zone.

Peridotite vs Eclogite 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 Eclogite Reserves. Peridotite is a dense, coarse-grained plutonic is the main constituent of the earth's mantle. Eclogite is an extreme metamorphic rock, formed by regional metamorphism of basalt rock under very high pressure and temperature. 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 Eclogite information and Peridotite vs Eclogite characteristics in the upcoming sections.
