Formation
Dunite is a plutonic ultramafic igneous rock consisting almost m olivine. It can be formed in two ways.
Monzogranite 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 Monzogranite 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. Dunite vs Monzogranite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Dunite and Properties of Monzogranite. Learn more about Dunite vs Monzogranite in the next section. The interior uses of Dunite include Decorative aggregates and Interior decoration whereas the interior uses of Monzogranite include Bathrooms, Countertops, Decorative aggregates, Entryways, Floor tiles, Homes, Hotels, Interior decoration, Kitchens and Stair treads. Due to some exceptional properties of Dunite and Monzogranite, they have various applications in construction industry. The uses of Dunite in construction industry include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Making natural cement, Raw material for the manufacture of mortar and that of Monzogranite include As dimension stone.
More about Dunite and Monzogranite
Here you can know more about Dunite and Monzogranite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Dunite and Monzogranite 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 Monzogranite includes Apatite, Biotite, Hornblende, Microcline, Perthite, Plagioclase, Quartz, Titanite, Zircon. You can also check out the list of all Igneous Rocks. When we have to compare Dunite vs Monzogranite, the texture, color and appearance plays an important role in determining the type of rock. Dunite is available in dark greenish - grey colors whereas, Monzogranite is available in black, grey, orange, pink, white colors. Appearance of Dunite is Rough and Shiny and that of Monzogranite is Veined or Pebbled. Properties of rock is another aspect for Dunite vs Monzogranite. The hardness of Dunite is 3.5-4 and that of Monzogranite is 6-7. The types of Dunite are Not Available whereas types of Monzogranite are Muscovite-Biotite-Metagranite, Muscovite-Metagranite, Schollen-Metagranite and Biotite-Metagranite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Dunite and Monzogranite is white. The specific heat capacity of Dunite is 1.25 kJ/Kg K and that of Monzogranite is 0.79 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Dunite is heat resistant, pressure resistant, wear resistant whereas Monzogranite is heat resistant, wear resistant.
