Formation

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

Sovites are formed due to low degrees of partial melting of rocks.

Dunite vs Sovite 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 Sovite Reserves. Dunite is a green to brownish coarse-grained igneous rock mainly consisting of olivine. Sovite is a coarse-grained variety of carbonatite which belongs to intrusive igneous rock. 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 Sovite information and Dunite vs Sovite characteristics in the upcoming sections.

More about Dunite and Sovite

Here you can know more about Dunite and Sovite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Dunite and Sovite 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 Sovite includes Ancylite, Apatite, Barite, Fluorite, Magnetite, Natrolite, Sodalite. You can also check out the list of all Igneous Rocks. When we have to compare Dunite vs Sovite, the texture, color and appearance plays an important role in determining the type of rock. Dunite is available in dark greenish - grey colors whereas, Sovite is available in black, brown, green, grey, pink, white colors. Appearance of Dunite is Rough and Shiny and that of Sovite is Dull, Banded and Foilated. Properties of rock is another aspect for Dunite vs Sovite. The hardness of Dunite is 3.5-4 and that of Sovite is 3. The types of Dunite are Dunite whereas types of Sovite are Carbonatite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Dunite and Sovite is white. The specific heat capacity of Dunite is 1.25 kJ/Kg K and that of Sovite is 0.84 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 Sovite is heat resistant, pressure resistant.
