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

Skarn vs Peridotite 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 Skarn and Peridotite Reserves. Skarns are formed during regional or contact metamorphism and from a variety of metasomatic processes involving fluids of magmatic, metamorphic, and/or marine origin. Peridotite is a dense, coarse-grained plutonic is the main constituent of the earth's mantle. 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 Skarn vs Peridotite information and Skarn vs Peridotite characteristics in the upcoming sections.

Skarn vs Peridotite Characteristics

Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Skarn vs Peridotite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Skarn and Properties of Peridotite. Learn more about Skarn vs Peridotite in the next section. The interior uses of Skarn include Decorative aggregates, Entryways and Interior decoration whereas the interior uses of Peridotite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Skarn and Peridotite, they have various applications in construction industry. The uses of Skarn in construction industry include As a flux in the production of steel and pig iron, As a sintering agent in steel industry to process iron ore, As dimension stone, Gold and silver production, Manufacture of magnesium and dolomite refractories and that of Peridotite include As dimension stone, Cobblestones.

More about Skarn and Peridotite

Here you can know more about Skarn and Peridotite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Skarn and Peridotite consists of mineral content and compound content. The mineral content of Skarn includes Calcite, Enstatite, Epidote, Garnet, Magnetite, Pyroxene, Titanite and mineral content of Peridotite includes Amphibole, Chromite, Garnet, Magnesium, Olivine, Phlogopite, Plagioclase, Pyroxene. You can also check out the list of all Metamorphic Rocks. When we have to compare Skarn vs Peridotite, the texture, color and appearance plays an important role in determining the type of rock. Skarn is available in black, brown, colourless, green, grey, white colors whereas, Peridotite is available in dark greenish - grey colors. Appearance of Skarn is Dull and that of Peridotite is Rough and Shiny. Properties of rock is another aspect for Skarn vs Peridotite. The hardness of Skarn is 6.5 and that of Peridotite is 5.5-6. The types of Skarn are Endoskarns whereas types of Peridotite are Dunite, Wehrlite, Harzburgite, Lherzolite and Pyrolite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Skarn is light to dark brown while that of Peridotite is white. The specific heat capacity of Skarn is 0.92 kJ/Kg K and that of Peridotite is 1.26 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Skarn is heat resistant whereas Peridotite is heat resistant, pressure resistant, wear resistant.
