Formation
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 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 vs Anorthosite 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. Monzonite vs Anorthosite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Monzonite and Properties of Anorthosite. Learn more about Monzonite vs Anorthosite in the next section. The interior uses of Monzonite include Decorative aggregates, Flooring and Interior decoration whereas the interior uses of Anorthosite include Decorative aggregates, Floor tiles, Homes and Interior decoration. Due to some exceptional properties of Monzonite and Anorthosite, they have various applications in construction industry. The uses of Monzonite in construction industry include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate and that of Anorthosite include As dimension stone, Cement manufacture, For road aggregate.
More about Monzonite and Anorthosite
Here you can know more about Monzonite and Anorthosite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Monzonite and Anorthosite consists of mineral content and compound content. The mineral content of Monzonite includes Albite, Amphibole, Apatite, Biotite, Feldspar, Hornblade, Ilmenite, Magnetite, Muscovite or Illite, Olivine, Plagioclase, Pyroxene, Quartz, Sulfides, Titanite, Zircon and mineral content of Anorthosite includes Amphibole, Clinopyroxene, Ilmenite, Magnetite, Olivine, Orthopyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Monzonite vs Anorthosite, the texture, color and appearance plays an important role in determining the type of rock. Monzonite is available in black, brown, light to dark grey, white colors whereas, Anorthosite is available in black, bluish - grey, brown, green, grey, light greenish grey, pink, white colors. Appearance of Monzonite is Shiny and that of Anorthosite is Layered, Banded, Veined and Shiny. Properties of rock is another aspect for Monzonite vs Anorthosite. The hardness of Monzonite is 6-7 and that of Anorthosite is 5-6. The types of Monzonite are Quartz Monzonite, Mangerite, Syenite and Diorite whereas types of Anorthosite are Proterozoic Anorthosite and Archean Anorthosite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Monzonite and Anorthosite is white. The specific heat capacity of Monzonite is 0.92 kJ/Kg K and that of Anorthosite 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.Monzonite is heat resistant, impact resistant, pressure resistant whereas Anorthosite is heat resistant, impact resistant, pressure resistant, scratch resistant, wear resistant.
