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.   
Monzonite 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.

Anorthosite vs Monzonite 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 Monzonite Reserves. Anorthosite is a granular igneous rock composed largely of labradorite or plagioclase. Monzonite is a granular igneous rock with composition between syenite and diorite and containing approximately equal amounts of orthoclase and plagioclase. 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 Monzonite information and Anorthosite vs Monzonite characteristics in the upcoming sections.

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

More about Anorthosite and Monzonite

Here you can know more about Anorthosite and Monzonite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Anorthosite and Monzonite consists of mineral content and compound content. The mineral content of Anorthosite includes Amphibole, Clinopyroxene, Ilmenite, Magnetite, Olivine, Orthopyroxene and mineral content of Monzonite includes Albite, Amphibole, Apatite, Biotite, Feldspar, Hornblade, Ilmenite, Magnetite, Muscovite or Illite, Olivine, Plagioclase, Pyroxene, Quartz, Sulfides, Titanite, Zircon. You can also check out the list of all Igneous Rocks. When we have to compare Anorthosite vs Monzonite, 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, Monzonite is available in black, brown, light to dark grey, white colors. Appearance of Anorthosite is Layered, Banded, Veined and Shiny and that of Monzonite is Shiny. Properties of rock is another aspect for Anorthosite vs Monzonite. The hardness of Anorthosite is 5-6 and that of Monzonite is 6-7. The types of Anorthosite are Proterozoic Anorthosite and Archean Anorthosite whereas types of Monzonite are Quartz Monzonite, Mangerite, Syenite and Diorite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Anorthosite and Monzonite is white. The specific heat capacity of Anorthosite is 0.84 kJ/Kg K and that of Monzonite 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 Monzonite is heat resistant, impact resistant, pressure resistant.
