Archaeological Significance
Formation
Kimberlite is an igneous rock and is the main source of diamonds. Its formation takes place deep beneath the Earth’s surface between 150 to 450 kilometres, and are erupted rapidly and violently.
Sovites are formed due to low degrees of partial melting of rocks.

Kimberlite vs Sovite 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. Kimberlite vs Sovite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Kimberlite and Properties of Sovite. Learn more about Kimberlite vs Sovite in the next section. The interior uses of Kimberlite include Countertops, Decorative aggregates, Homes and Interior decoration whereas the interior uses of Sovite include Decorative aggregates and Homes. Due to some exceptional properties of Kimberlite and Sovite, they have various applications in construction industry. The uses of Kimberlite in construction industry include As a flux in the production of steel and pig iron, As a sintering agent in steel industry to process iron ore, As dimension stone, Cement manufacture, For road aggregate, Making natural cement, Manufacture of magnesium and dolomite refractories and that of Sovite include As a flux in the production of steel and pig iron, As a sintering agent in steel industry to process iron ore, As dimension stone, Cement manufacture, For road aggregate, Making natural cement, Manufacture of magnesium and dolomite refractories.
More about Kimberlite and Sovite
Here you can know more about Kimberlite and Sovite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Kimberlite and Sovite consists of mineral content and compound content. The mineral content of Kimberlite includes Garnet, Olivine, Phlogopite, 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 Kimberlite vs Sovite, the texture, color and appearance plays an important role in determining the type of rock. Kimberlite is available in black, bluish - grey, brown, dark greenish - grey, green, grey colors whereas, Sovite is available in black, brown, green, grey, pink, white colors. Appearance of Kimberlite is Dull and Banded and that of Sovite is Dull, Banded and Foilated. Properties of rock is another aspect for Kimberlite vs Sovite. The hardness of Kimberlite is 6-7 and that of Sovite is 3. The types of Kimberlite are Basaltic Kimberlites and Micaceous Kimberlites 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 Kimberlite and Sovite is white. The specific heat capacity of Kimberlite is 0.92 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.Kimberlite is heat resistant, impact resistant whereas Sovite is heat resistant, pressure resistant.
