Formation

Formation
Anorthosite is a phaneritic, intrusive igneous rock which is characterized by a predominance of plagioclase feldspar which is almost 90–100%, and a minimal mafic component.   
Dolomite rocks are originally deposited as calcite or aragonite rich limestone, but during diagenesis process, the calcite or aragonite is transformed into dolomite.

Anorthosite 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 Anorthosite and Dolomite Reserves. Anorthosite is a granular igneous rock composed largely of labradorite or plagioclase. 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 Anorthosite vs Dolomite information and Anorthosite vs Dolomite characteristics in the upcoming sections.

Anorthosite 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. Anorthosite vs Dolomite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Anorthosite and Properties of Dolomite. Learn more about Anorthosite vs Dolomite in the next section. The interior uses of Anorthosite include Decorative aggregates, Floor tiles, Homes and Interior decoration whereas the interior uses of Dolomite include Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Anorthosite and Dolomite, they have various applications in construction industry. The uses of Anorthosite in construction industry include As dimension stone, Cement manufacture, 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 Anorthosite and Dolomite

Here you can know more about Anorthosite and Dolomite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Anorthosite and Dolomite consists of mineral content and compound content. The mineral content of Anorthosite includes Amphibole, Clinopyroxene, Ilmenite, Magnetite, Olivine, Orthopyroxene 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 Anorthosite vs Dolomite, the texture, color and appearance plays an important role in determining the type of rock. Anorthosite is available in black, bluish - grey, brown, green, grey, light greenish grey, pink, white colors whereas, Dolomite is available in black, brown, colourless, green, grey, pink, white colors. Appearance of Anorthosite is Layered, Banded, Veined and Shiny and that of Dolomite is Glassy or Pearly. Properties of rock is another aspect for Anorthosite vs Dolomite. The hardness of Anorthosite is 5-6 and that of Dolomite is 3.5-4. The types of Anorthosite are Proterozoic Anorthosite and Archean Anorthosite 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 Anorthosite and Dolomite is white. The specific heat capacity of Anorthosite is 0.84 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.Anorthosite is heat resistant, impact resistant, pressure resistant, scratch resistant, wear resistant whereas Dolomite is heat resistant, pressure resistant, wear resistant.
