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.
Claystone is a fine-grained, dark gray to pink sedimentary rock which mainly consists of compacted and hardened clay

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.
Claystone is generally quite soft, but can be hard and brittle. It forms due to weathering of mudstone.

Kimberlite vs Claystone 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 Claystone characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Kimberlite and Properties of Claystone. Learn more about Kimberlite vs Claystone in the next section. The interior uses of Kimberlite include Countertops, Decorative aggregates, Homes and Interior decoration whereas the interior uses of Claystone include Decorative aggregates, Entryways, Floor tiles, Homes and Interior decoration.

More about Kimberlite and Claystone
Here you can know more about Kimberlite and Claystone. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Kimberlite and Claystone consists of mineral content and compound content. The mineral content of Kimberlite includes Garnet, Olivine, Phlogopite, Pyroxene and mineral content of Claystone includes Biotite, Chlorite, Feldspar, Micas, Muscovite or Illite, Plagioclase, Pyrite, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Kimberlite vs Claystone, 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, Claystone is available in black, blue, brown, green, grey, orange, red, white, yellow colors. Appearance of Kimberlite is Dull and Banded and that of Claystone is Rough and Dull. Properties of rock is another aspect for Kimberlite vs Claystone. The hardness of Kimberlite is 6-7 and that of Claystone is 3.5-4. The types of Kimberlite are Basaltic Kimberlites and Micaceous Kimberlites whereas types of Claystone 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 Claystone is white. The specific heat capacity of Kimberlite is 0.92 kJ/Kg K and that of Claystone 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 Claystone is heat resistant, impact resistant.
