Formation

Formation

Pyrolite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.
Dolomite rocks are originally deposited as calcite or aragonite rich limestone, but during diagenesis process, the calcite or aragonite is transformed into dolomite.

Pyrolite 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 Pyrolite and Dolomite Reserves. Pyrolite is an igneous rock consisting of about three parts of peridotite and one part of basalt. 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 Pyrolite vs Dolomite information and Pyrolite vs Dolomite characteristics in the upcoming sections.

Pyrolite 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. Pyrolite vs Dolomite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Pyrolite and Properties of Dolomite. Learn more about Pyrolite vs Dolomite in the next section. The interior uses of Pyrolite 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 Pyrolite and Dolomite, they have various applications in construction industry. The uses of Pyrolite in construction industry include As dimension stone, Cobblestones 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 Pyrolite and Dolomite

Here you can know more about Pyrolite and Dolomite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Pyrolite and Dolomite consists of mineral content and compound content. The mineral content of Pyrolite includes Amphibole, Chromite, Garnet, Magnesium, Olivine, Phlogopite, Plagioclase, Pyroxene and mineral content of Dolomite includes Clay Minerals, Pyrite, Quartz, Sulfides. You can also check out the list of all Igneous Rocks. When we have to compare Pyrolite vs Dolomite, the texture, color and appearance plays an important role in determining the type of rock. Pyrolite is available in dark greenish - grey colors whereas, Dolomite is available in black, brown, green, grey, pink, white colors. Appearance of Pyrolite is Rough and Shiny and that of Dolomite is Glassy or Pearly. Properties of rock is another aspect for Pyrolite vs Dolomite. The hardness of Pyrolite is 5.5-6 and that of Dolomite is 3.5-4. The types of Pyrolite are Dunite, Wehrlite, Harzburgite, Lherzolite 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 Pyrolite and Dolomite is white. The specific heat capacity of Pyrolite is 1.25 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.Pyrolite is heat resistant, pressure resistant, wear resistant whereas Dolomite is heat resistant, pressure resistant, wear resistant.
