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.
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.

Skarn 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 Skarn and Granulite 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. 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 Skarn vs Granulite information and Skarn vs Granulite characteristics in the upcoming sections.

Skarn vs Granulite 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 Granulite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Skarn and Properties of Granulite. Learn more about Skarn vs Granulite in the next section. The interior uses of Skarn include Decorative aggregates, Entryways and Interior decoration whereas the interior uses of Granulite include Bathrooms, Countertops, Decorative aggregates, Entryways, Flooring, Homes, Hotels, Interior decoration, Kitchens and Stair treads. Due to some exceptional properties of Skarn and Granulite, 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 Granulite include As dimension stone, Building houses or walls.

More about Skarn and Granulite

Here you can know more about Skarn and Granulite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Skarn and Granulite consists of mineral content and compound content. The mineral content of Skarn includes Calcite, Enstatite, Epidote, Garnet, Magnetite, Pyroxene, Titanite 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 Metamorphic Rocks. When we have to compare Skarn vs Granulite, 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, Granulite is available in black, brown colors. Appearance of Skarn is Dull and that of Granulite is Veined or Pebbled. Properties of rock is another aspect for Skarn vs Granulite. The hardness of Skarn is 6.5 and that of Granulite is 6-7. The types of Skarn are Endoskarns 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 Skarn is light to dark brown while that of Granulite is white. The specific heat capacity of Skarn is 0.92 kJ/Kg K and that of Granulite is 0.14 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 Granulite is heat resistant, wear resistant.
