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.
Andesite is a fine-grained igneous rock that forms when the magma is erupted onto the surface and is crystallized quickly.

Due to some exceptional properties of Monzonite and Andesite, 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 Andesite include Cobblestones, Construction aggregate, For road aggregate.
More about Monzonite and Andesite
Here you can know more about Monzonite and Andesite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Monzonite and Andesite 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 Andesite includes Amphibole, Apatite, Biotite, Feldspar, Garnet, Hornblade, Ilmenite, Magnetite, Plagioclase, Pyroxene, Zircon. You can also check out the list of all Igneous Rocks. When we have to compare Monzonite vs Andesite, 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, Andesite is available in bluish - grey, grey, pink, yellow colors. Appearance of Monzonite is Shiny and that of Andesite is Dull and Soft. Properties of rock is another aspect for Monzonite vs Andesite. The hardness of Monzonite is 6-7 and that of Andesite is 7. The types of Monzonite are Quartz Monzonite, Mangerite, Syenite and Diorite whereas types of Andesite are Icelandite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Monzonite and Andesite is white. The specific heat capacity of Monzonite is 0.92 kJ/Kg K and that of Andesite is 2.39 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 Andesite is heat resistant, pressure resistant, wear resistant.
