Granulite vs Evaporite 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 Evaporite Reserves. Granulite is fine to medium grained metamorphic rock with a granular of polygonal crystals.. A water-soluble mineral sediment resulting from concentration and crystallization by evaporation from an aqueous solution. 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 Evaporite information and Granulite vs Evaporite characteristics in the upcoming sections.

Granulite vs Evaporite 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 Evaporite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Granulite and Properties of Evaporite. Learn more about Granulite vs Evaporite 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 Evaporite include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration. Due to some exceptional properties of Granulite and Evaporite, 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 Evaporite 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, Cement manufacture, For road aggregate, Making natural cement, Manufacture of magnesium and dolomite refractories.

More about Granulite and Evaporite

Here you can know more about Granulite and Evaporite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Granulite and Evaporite 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 Evaporite includes Calcite, Cancrinite, Gypsum, Kyanite, Magnetite. You can also check out the list of all Metamorphic Rocks. When we have to compare Granulite vs Evaporite, the texture, color and appearance plays an important role in determining the type of rock. Granulite is available in black, brown colors whereas, Evaporite is available in green, grey, silver, white colors. Appearance of Granulite is Veined or Pebbled and that of Evaporite is Glassy, Vesicular and Foilated. Properties of rock is another aspect for Granulite vs Evaporite. The hardness of Granulite is 6-7 and that of Evaporite is 2-3. The types of Granulite are Metamorphic rock whereas types of Evaporite are Sedimentary rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Granulite and Evaporite is white. The specific heat capacity of Granulite is 0.14 kJ/Kg K and that of Evaporite 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.Granulite is heat resistant, wear resistant whereas Evaporite is heat resistant, pressure resistant.
