Formation

Formation
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Metapelite is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.  
Dolomite rocks are originally deposited as calcite or aragonite rich limestone, but during diagenesis process, the calcite or aragonite is transformed into dolomite.

Metapelite vs Dolomite 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 Metapelite and Dolomite Reserves. Metapelite is an old and currently not widely used field geological term for a clay rich fine-grained clastic sediment or sedimentary rock, i.e. mud or a mudstone. Dolomite is a sedimentary rock containing more than 50 percent of the mineral dolomite by weight. 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 Metapelite vs Dolomite information and Metapelite vs Dolomite characteristics in the upcoming sections.

Metapelite vs Dolomite 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. Metapelite vs Dolomite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Metapelite and Properties of Dolomite. Learn more about Metapelite vs Dolomite in the next section. The interior uses of Metapelite include Decorative aggregates and Interior decoration whereas the interior uses of Dolomite include Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Metapelite and Dolomite, they have various applications in construction industry. The uses of Metapelite in construction industry include Cement manufacture, Construction aggregate, For road aggregate and that of Dolomite 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.

More about Metapelite and Dolomite

Here you can know more about Metapelite and Dolomite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Metapelite and Dolomite consists of mineral content and compound content. The mineral content of Metapelite includes Albite, Chlorite, Quartz and mineral content of Dolomite includes Clay Minerals, Pyrite, Quartz, Sulfides. You can also check out the list of all Metamorphic Rocks. When we have to compare Metapelite vs Dolomite, the texture, color and appearance plays an important role in determining the type of rock. Metapelite is available in dark greenish - grey, green, light green, light greenish grey colors whereas, Dolomite is available in black, brown, green, grey, pink, white colors. Appearance of Metapelite is Banded and that of Dolomite is Glassy or Pearly. Properties of rock is another aspect for Metapelite vs Dolomite. The hardness of Metapelite is 5-6 and that of Dolomite is 3.5-4. The types of Metapelite are Metamorphic rock whereas types of Dolomite are Boninite and Jasperoid. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Metapelite is while that of Dolomite is white. The specific heat capacity of Metapelite is 0.72 kJ/Kg K and that of Dolomite 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.Metapelite is heat resistant, impact resistant, pressure resistant whereas Dolomite is heat resistant, pressure resistant, wear resistant.
