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.   
Benmoreite is a type of Igneous rock which is formed through the cooling and solidification of lava or magma. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

Anorthosite vs Benmoreite 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 Benmoreite Reserves. Anorthosite is a granular igneous rock composed largely of labradorite or plagioclase. An iron rich extrusive rock found as a member of the alkali basalt magma series. 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 Benmoreite information and Anorthosite vs Benmoreite characteristics in the upcoming sections.

Anorthosite vs Benmoreite 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 Benmoreite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Anorthosite and Properties of Benmoreite. Learn more about Anorthosite vs Benmoreite in the next section. The interior uses of Anorthosite include Decorative aggregates, Floor tiles, Homes and Interior decoration whereas the interior uses of Benmoreite include Floor tiles, Homes, Hotels and Kitchens. Due to some exceptional properties of Anorthosite and Benmoreite, 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 Benmoreite include As dimension stone, Cobblestones, Rail track ballast, Roadstone.

More about Anorthosite and Benmoreite

Here you can know more about Anorthosite and Benmoreite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Anorthosite and Benmoreite consists of mineral content and compound content. The mineral content of Anorthosite includes Amphibole, Clinopyroxene, Ilmenite, Magnetite, Olivine, Orthopyroxene and mineral content of Benmoreite includes Alkali feldspar, Biotite, Olivine, Plagioclase, Pyroxene, Sodic plagioclase. You can also check out the list of all Igneous Rocks. When we have to compare Anorthosite vs Benmoreite, 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, Benmoreite is available in black, brown, light to dark grey colors. Appearance of Anorthosite is Layered, Banded, Veined and Shiny and that of Benmoreite is Rough and Dull. Properties of rock is another aspect for Anorthosite vs Benmoreite. The hardness of Anorthosite is 5-6 and that of Benmoreite is 6. The types of Anorthosite are Proterozoic Anorthosite and Archean Anorthosite whereas types of Benmoreite are Alkaline Basalt, Boninite, High Alumina Basalt, Mid Ocean Ridge Basalt (MORB) and Tholeiitic Basalt. 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 Benmoreite is black. The specific heat capacity of Anorthosite is 0.84 kJ/Kg K and that of Benmoreite is 0.84 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 Benmoreite is heat resistant, pressure resistant, wear resistant.
