1 Definition
1.1 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.
Chalk is a soft, white, powdery limestone consisting mainly of fossil shells of foraminifers

5 Formation
5.1 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.
Chalk is formed from lime mud, which accumulates on the sea floor which is then transformed into rock by geological processes.

Kimberlite vs Chalk 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 Kimberlite and Chalk Reserves. Kimberlite is a rare, blue-tinged, coarse-grained intrusive igneous rock, which sometimes contains diamonds and is mostly found in South Africa and Siberia.. Chalk is a soft, white, powdery limestone consisting mainly of fossil shells of foraminifers. 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 Kimberlite vs Chalk information and Kimberlite vs Chalk characteristics in the upcoming sections.

Kimberlite vs Chalk 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 Chalk characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Kimberlite and Properties of Chalk. Learn more about Kimberlite vs Chalk in the next section. The interior uses of Kimberlite include Countertops, Decorative aggregates, Homes and Interior decoration whereas the interior uses of Chalk include Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Kimberlite and Chalk, 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 Chalk include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Making natural cement, Raw material for manufacture of quicklime and slaked lime, Source of calcium.

More about Kimberlite and Chalk

Here you can know more about Kimberlite and Chalk. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Kimberlite and Chalk consists of mineral content and compound content. The mineral content of Kimberlite includes Garnet, Olivine, Phlogopite, Pyroxene and mineral content of Chalk includes Calcite, Clay, Clay Minerals, Quartz, Sand. You can also check out the list of all Igneous Rocks. When we have to compare Kimberlite vs Chalk, 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, Chalk is available in grey, white, yellow colors. Appearance of Kimberlite is Dull and Banded and that of Chalk is Soft. Properties of rock is another aspect for Kimberlite vs Chalk. The hardness of Kimberlite is 6-7 and that of Chalk is 1. The types of Kimberlite are Basaltic Kimberlites and Micaceous Kimberlites whereas types of Chalk are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Kimberlite and Chalk is white. The specific heat capacity of Kimberlite is 0.92 kJ/Kg K and that of Chalk is 0.90 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 Chalk is heat resistant.
