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.
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Serpentinite is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.

Anorthosite vs Serpentinite 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 Serpentinite Reserves. Anorthosite is a granular igneous rock composed largely of labradorite or plagioclase. A hydration and metamorphic transformation of ultramafic rock from the Earth's mantle is called as serpentinization, a group of minerals is formed by serpentinization compose rock 'serpentinite'.. 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 Serpentinite information and Anorthosite vs Serpentinite characteristics in the upcoming sections.

Anorthosite vs Serpentinite 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 Serpentinite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Anorthosite and Properties of Serpentinite. Learn more about Anorthosite vs Serpentinite in the next section. The interior uses of Anorthosite include Decorative aggregates, Floor tiles, Homes and Interior decoration whereas the interior uses of Serpentinite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Anorthosite and Serpentinite, 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 Serpentinite include As dimension stone, Cement manufacture, For road aggregate, Making natural cement.

More about Anorthosite and Serpentinite

Here you can know more about Anorthosite and Serpentinite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Anorthosite and Serpentinite consists of mineral content and compound content. The mineral content of Anorthosite includes Amphibole, Clinopyroxene, Ilmenite, Magnetite, Olivine, Orthopyroxene and mineral content of Serpentinite includes Carbonate, Magnetite, Pyrrhotite, Serpentine, Sulfides. You can also check out the list of all Igneous Rocks. When we have to compare Anorthosite vs Serpentinite, 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, Serpentinite is available in black, brown, green, grey, white colors. Appearance of Anorthosite is Layered, Banded, Veined and Shiny and that of Serpentinite is Rough and Dull. Properties of rock is another aspect for Anorthosite vs Serpentinite. The hardness of Anorthosite is 5-6 and that of Serpentinite is 3-5. The types of Anorthosite are Proterozoic Anorthosite and Archean Anorthosite whereas types of Serpentinite are Jadeitite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Anorthosite is white while that of Serpentinite is white, greenish white or grey. The specific heat capacity of Anorthosite is 0.84 kJ/Kg K and that of Serpentinite is 0.95 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 Serpentinite is heat resistant.
