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

More about Monzonite and Dunite
Here you can know more about Monzonite and Dunite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Monzonite and Dunite 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 Dunite includes Amphibole, Chromite, Garnet, Magnesium, Olivine, Phlogopite, Plagioclase, Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Monzonite vs Dunite, 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, Dunite is available in dark greenish - grey colors. Appearance of Monzonite is Shiny and that of Dunite is Rough and Shiny. Properties of rock is another aspect for Monzonite vs Dunite. The hardness of Monzonite is 6-7 and that of Dunite is 3.5-4. The types of Monzonite are Quartz Monzonite, Mangerite, Syenite and Diorite whereas types of Dunite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Monzonite and Dunite is white. The specific heat capacity of Monzonite is 0.92 kJ/Kg K and that of Dunite is 1.25 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 Dunite is heat resistant, pressure resistant, wear resistant.
