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.

Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Serpentinite is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.

Peridotite vs Serpentinite 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 Serpentinite Reserves. Peridotite is a dense, coarse-grained plutonic is the main constituent of the earth's mantle. A hydration and metamorphic transformation of ultramafic rock from the Earth's mantle is called as serpentinization, a group of minerals is formed by serpentinization compose rock 'serpentinite'.. 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 Serpentinite information and Peridotite vs Serpentinite characteristics in the upcoming sections.

More about Peridotite and Serpentinite

Here you can know more about Peridotite and Serpentinite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Peridotite and Serpentinite 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 Serpentinite includes Carbonate, Magnetite, Pyrrhotite, Serpentine, Sulfides. You can also check out the list of all Igneous Rocks. When we have to compare Peridotite vs Serpentinite, the texture, color and appearance plays an important role in determining the type of rock. Peridotite is available in dark greenish - grey colors whereas, Serpentinite is available in black, brown, colourless, green, grey, white colors. Appearance of Peridotite is Rough and Shiny and that of Serpentinite is Rough and Dull. Properties of rock is another aspect for Peridotite vs Serpentinite. The hardness of Peridotite is 5.5-6 and that of Serpentinite is 3-5. The types of Peridotite are Dunite, Wehrlite, Harzburgite, Lherzolite and Pyrolite whereas types of Serpentinite are Jadeitite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Peridotite is white while that of Serpentinite is white, greenish white or grey. The specific heat capacity of Peridotite is 1.26 kJ/Kg K and that of Serpentinite is 0.95 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Peridotite is heat resistant, pressure resistant, wear resistant whereas Serpentinite is heat resistant.
