Definition
Kimberlite is a rare, blue-tinged, coarse-grained intrusive igneous rock, which sometimes contains diamonds and is mostly found in South Africa and Siberia.
A sedimentary rock, deposit of a submarine turbidity currents and are composed of layered particles
Origin
Kimberley, South Africa
European Foreland Basins
Discoverer
Unknown
Arnold H. Bouma
Etymology
From Kimberley + -ite, from the name of the South African town of Kimberley where the rock was first found.
From Medieval Latin turbiditas, from Latin turbidus (turbid). Turbidity current is from 1939

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.
Turbidite is a type of sedimentary rock formed when a river carries or transports pieces of broken rock as it flows. These particles then settle down and are subjected to high temperature and pressures hence forming Turbidite.

Kimberlite vs Turbidite 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 Turbidite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Kimberlite and Properties of Turbidite. Learn more about Kimberlite vs Turbidite in the next section. The interior uses of Kimberlite include Countertops, Decorative aggregates, Homes and Interior decoration whereas the interior uses of Turbidite include Bathrooms, Countertops, Decorative aggregates, Flooring, Homes and Interior decoration. Due to some exceptional properties of Kimberlite and Turbidite, 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 Turbidite include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Making natural cement.
More about Kimberlite and Turbidite
Here you can know more about Kimberlite and Turbidite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Kimberlite and Turbidite consists of mineral content and compound content. The mineral content of Kimberlite includes Garnet, Olivine, Phlogopite, Pyroxene and mineral content of Turbidite includes Coesite, Quartz, Sand. You can also check out the list of all Igneous Rocks. When we have to compare Kimberlite vs Turbidite, 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, Turbidite is available in black, brown, colourless, green, grey, pink colors. Appearance of Kimberlite is Dull and Banded and that of Turbidite is Dull and Banded. Properties of rock is another aspect for Kimberlite vs Turbidite. The hardness of Kimberlite is 6-7 and that of Turbidite is 3. The types of Kimberlite are Basaltic Kimberlites and Micaceous Kimberlites whereas types of Turbidite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Kimberlite is white while that of Turbidite is white, greenish white or grey. The specific heat capacity of Kimberlite is 0.92 kJ/Kg K and that of Turbidite is 0.92 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 Turbidite is heat resistant.
