Definition

Granulite is fine to medium grained metamorphic rock with a granular of polygonal crystals.

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'.

Formation

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.

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.

Granulite 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 Granulite and Serpentinite Reserves. Granulite is fine to medium grained metamorphic rock with a granular of polygonal crystals.. 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 Granulite vs Serpentinite information and Granulite vs Serpentinite characteristics in the upcoming sections.

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

More about Granulite and Serpentinite

Here you can know more about Granulite and Serpentinite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Granulite and Serpentinite consists of mineral content and compound content. The mineral content of Granulite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Quartz and mineral content of Serpentinite includes Carbonate, Magnetite, Pyrrhotite, Serpentine, Sulfides. You can also check out the list of all Metamorphic Rocks. When we have to compare Granulite vs Serpentinite, the texture, color and appearance plays an important role in determining the type of rock. Granulite is available in black, brown colors whereas, Serpentinite is available in black, brown, green, grey, white colors. Appearance of Granulite is Veined or Pebbled and that of Serpentinite is Rough and Dull. Properties of rock is another aspect for Granulite vs Serpentinite. The hardness of Granulite is 6-7 and that of Serpentinite is 3-5. The types of Granulite are Metamorphic rock 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 Granulite is white while that of Serpentinite is white, greenish white or grey. The specific heat capacity of Granulite is 0.14 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.Granulite is heat resistant, wear resistant whereas Serpentinite is heat resistant.
