Definition

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'.

Skarns are formed during regional or contact metamorphism and from a variety of metasomatic processes involving fluids of magmatic, metamorphic, and/or marine origin

Formation

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.

Serpentinite vs Skarn 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 Serpentinite and Skarn Reserves. 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'.. Skarns are formed during regional or contact metamorphism and from a variety of metasomatic processes involving fluids of magmatic, metamorphic, and/or marine origin. 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 Serpentinite vs Skarn information and Serpentinite vs Skarn characteristics in the upcoming sections.

Serpentinite vs Skarn 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. Serpentinite vs Skarn characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Serpentinite and Properties of Skarn. Learn more about Serpentinite vs Skarn in the next section. The interior uses of Serpentinite include Decorative aggregates and Interior decoration whereas the interior uses of Skarn include Decorative aggregates, Entryways and Interior decoration. Due to some exceptional properties of Serpentinite and Skarn, they have various applications in construction industry. The uses of Serpentinite in construction industry include As dimension stone, Cement manufacture, For road aggregate, Making natural cement and that of Skarn 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.

More about Serpentinite and Skarn

Here you can know more about Serpentinite and Skarn. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Serpentinite and Skarn consists of mineral content and compound content. The mineral content of Serpentinite includes Carbonate, Magnetite, Pyrrhotite, Serpentine, Sulfides and mineral content of Skarn includes Calcite, Enstatite, Epidote, Garnet, Magnetite, Pyroxene, Titanite. You can also check out the list of all Metamorphic Rocks. When we have to compare Serpentinite vs Skarn, the texture, color and appearance plays an important role in determining the type of rock. Serpentinite is available in black, brown, green, grey, white colors whereas, Skarn is available in black, brown, green, grey, white colors. Appearance of Serpentinite is Rough and Dull and that of Skarn is Dull. Properties of rock is another aspect for Serpentinite vs Skarn. The hardness of Serpentinite is 3-5 and that of Skarn is 6.5. The types of Serpentinite are Jadeitite whereas types of Skarn are Endoskarns. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Serpentinite is white, greenish white or grey while that of Skarn is light to dark brown. The specific heat capacity of Serpentinite is 0.95 kJ/Kg K and that of Skarn is 0.92 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Serpentinite is heat resistant whereas Skarn is heat resistant.
