Anorthosite vs Kimberlite

1 Definition
1.1 Definition
Anorthosite is a granular igneous rock composed largely of labradorite or plagioclase
Kimberlite is a rare, blue-tinged, coarse-grained intrusive igneous rock, which sometimes contains diamonds and is mostly found in South Africa and Siberia.

5 Formation
5.1 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.
Kimberlite is an igneous rock and is the main source of diamonds. Its formation takes place deep beneath the Earth’s surface between 150 to 450 kilometres, and are erupted rapidly and violently.

Anorthosite vs Kimberlite 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 Kimberlite Reserves. Anorthosite is a granular igneous rock composed largely of labradorite or plagioclase. Kimberlite is a rare, blue-tinged, coarse-grained intrusive igneous rock, which sometimes contains diamonds and is mostly found in South Africa and Siberia.. 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 Kimberlite information and Anorthosite vs Kimberlite characteristics in the upcoming sections.

Anorthosite vs Kimberlite 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 Kimberlite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Anorthosite and Properties of Kimberlite. Learn more about Anorthosite vs Kimberlite in the next section. The interior uses of Anorthosite include Decorative aggregates, Floor tiles, Homes and Interior decoration whereas the interior uses of Kimberlite include Countertops, Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Anorthosite and Kimberlite, 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 Kimberlite 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 Anorthosite and Kimberlite

Here you can know more about Anorthosite and Kimberlite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Anorthosite and Kimberlite consists of mineral content and compound content. The mineral content of Anorthosite includes Amphibole, Clinopyroxene, Ilmenite, Magnetite, Olivine, Orthopyroxene and mineral content of Kimberlite includes Garnet, Olivine, Phlogopite, Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Anorthosite vs Kimberlite, 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, Kimberlite is available in black, bluish - grey, brown, dark greenish - grey, green, grey colors. Appearance of Anorthosite is Layered, Banded, Veined and Shiny and that of Kimberlite is Dull and Banded. Properties of rock is another aspect for Anorthosite vs Kimberlite. The hardness of Anorthosite is 5-6 and that of Kimberlite is 6-7. The types of Anorthosite are Proterozoic Anorthosite and Archean Anorthosite whereas types of Kimberlite are Basaltic Kimberlites and Micaceous Kimberlites. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Anorthosite and Kimberlite is white. The specific heat capacity of Anorthosite is 0.84 kJ/Kg K and that of Kimberlite 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 Kimberlite is heat resistant, impact resistant.
