Formation

Formation

Andesite is a fine-grained igneous rock that forms when the magma is erupted onto the surface and is crystallized quickly.
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 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 Andesite and Monzonite Reserves. Andesite is a dark, fine-grained, brown or greyish intermediate volcanic rock which is a commonly found in lava. 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 Andesite vs Monzonite information and Andesite vs Monzonite characteristics in the upcoming sections.

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

More about Andesite and Monzonite

Here you can know more about Andesite and Monzonite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Andesite and Monzonite consists of mineral content and compound content. The mineral content of Andesite includes Amphibole, Apatite, Biotite, Feldspar, Garnet, Hornblade, Ilmenite, Magnetite, Plagioclase, Pyroxene, Zircon 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 Andesite vs Monzonite, the texture, color and appearance plays an important role in determining the type of rock. Andesite is available in bluish - grey, grey, pink, yellow colors whereas, Monzonite is available in black, brown, light to dark grey, white colors. Appearance of Andesite is Dull and Soft and that of Monzonite is Shiny. Properties of rock is another aspect for Andesite vs Monzonite. The hardness of Andesite is 7 and that of Monzonite is 6-7. The types of Andesite are Icelandite 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 Andesite and Monzonite is white. The specific heat capacity of Andesite is 2.39 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.Andesite is heat resistant, pressure resistant, wear resistant whereas Monzonite is heat resistant, impact resistant, pressure resistant.
