Formation

Formation

Dolomite rocks are originally deposited as calcite or aragonite rich limestone, but during diagenesis process, the calcite or aragonite is transformed into dolomite.
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.

Dolomite 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 Dolomite and Granulite Reserves. Dolomite is a sedimentary rock containing more than 50 percent of the mineral dolomite by weight. 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 Dolomite vs Granulite information and Dolomite vs Granulite characteristics in the upcoming sections.

Dolomite 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. Dolomite vs Granulite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Dolomite and Properties of Granulite. Learn more about Dolomite vs Granulite in the next section. The interior uses of Dolomite include Decorative aggregates, Homes 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 Dolomite and Granulite, they have various applications in construction industry. The uses of Dolomite 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, Cement manufacture, For road aggregate, Making natural cement, Manufacture of magnesium and dolomite refractories, Production of glass and ceramics, Serves as an oil and gas reservoir rock and that of Granulite include As dimension stone, Building houses or walls.

More about Dolomite and Granulite

Here you can know more about Dolomite and Granulite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Dolomite and Granulite consists of mineral content and compound content. The mineral content of Dolomite includes Clay Minerals, Pyrite, Quartz, Sulfides 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 Sedimentary Rocks. When we have to compare Dolomite vs Granulite, the texture, color and appearance plays an important role in determining the type of rock. Dolomite is available in black, brown, green, grey, pink, white colors whereas, Granulite is available in black, brown colors. Appearance of Dolomite is Glassy or Pearly and that of Granulite is Veined or Pebbled. Properties of rock is another aspect for Dolomite vs Granulite. The hardness of Dolomite is 3.5-4 and that of Granulite is 6-7. The types of Dolomite are Boninite and Jasperoid whereas types of Granulite are Metamorphic rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Dolomite and Granulite is white. The specific heat capacity of Dolomite 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.Dolomite is heat resistant, pressure resistant, wear resistant whereas Granulite is heat resistant, wear resistant.
