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.

Granulite is a fine-grained granular metamorphic rock in which the main component minerals are feldspars and quartz and forms at high temperature and pressure conditions.

Peridotite vs Granulite 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 Granulite Reserves. Peridotite is a dense, coarse-grained plutonic is the main constituent of the earth's mantle. Granulite is fine to medium grained metamorphic rock with a granular of polygonal crystals.. 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 Granulite information and Peridotite vs Granulite characteristics in the upcoming sections.

Due to some exceptional properties of Peridotite and Granulite, they have various applications in construction industry. The uses of Peridotite in construction industry include As dimension stone, Cobblestones and that of Granulite include As dimension stone, Building houses or walls.

More about Peridotite and Granulite

Here you can know more about Peridotite and Granulite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Peridotite and Granulite consists of mineral content and compound content. The mineral content of Peridotite includes Amphibole, Chromite, Garnet, Magnesium, Olivine, Phlogopite, Plagioclase, Pyroxene and mineral content of Granulite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Peridotite vs Granulite, the texture, color and appearance plays an important role in determining the type of rock. Peridotite is available in dark greenish - grey colors whereas, Granulite is available in black, brown colors. Appearance of Peridotite is Rough and Shiny and that of Granulite is Veined or Pebbled. Properties of rock is another aspect for Peridotite vs Granulite. The hardness of Peridotite is 5.5-6 and that of Granulite is 6-7. The types of Peridotite are Dunite, Wehrlite, Harzburgite, Lherzolite and Pyrolite whereas types of Granulite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Peridotite and Granulite is white. The specific heat capacity of Peridotite is 1.26 kJ/Kg K and that of Granulite is 0.14 kJ/Kg K.
