Formation

Dunite is a plutonic ultramafic igneous rock consisting almost m olivine. It can be formed in two ways.

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.

Dunite 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 Dunite and Monzonite Reserves. Dunite is a green to brownish coarse-grained igneous rock mainly consisting of olivine. 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 Dunite vs Monzonite information and Dunite vs Monzonite characteristics in the upcoming sections.

More about Dunite and Monzonite

Here you can know more about Dunite and Monzonite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Dunite and Monzonite consists of mineral content and compound content. The mineral content of Dunite includes Amphibole, Chromite, Garnet, Magnesium, Olivine, Phlogopite, Plagioclase, Pyroxene 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 Dunite vs Monzonite, the texture, color and appearance plays an important role in determining the type of rock. Dunite is available in dark greenish - grey colors whereas, Monzonite is available in black, brown, light to dark grey, white colors. Appearance of Dunite is Rough and Shiny and that of Monzonite is Shiny. Properties of rock is another aspect for Dunite vs Monzonite. The hardness of Dunite is 3.5-4 and that of Monzonite is 6-7. The types of Dunite are Dunite 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 Dunite and Monzonite is white.
