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 carbonate rock which is matrix supported and contains over 10% allochems in a carbonate mud matrix.

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

Kimberlite vs Wackestone 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 Wackestone characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Kimberlite and Properties of Wackestone. Learn more about Kimberlite vs Wackestone in the next section. The interior uses of Kimberlite include Countertops, Decorative aggregates, Homes and Interior decoration whereas the interior uses of Wackestone include Decorative aggregates, Flooring and Interior decoration. Due to some exceptional properties of Kimberlite and Wackestone, 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 Wackestone include Cement manufacture, Construction aggregate, For road aggregate, Making natural cement, Raw material for the manufacture of mortar.
More about Kimberlite and Wackestone
Here you can know more about Kimberlite and Wackestone. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Kimberlite and Wackestone consists of mineral content and compound content. The mineral content of Kimberlite includes Garnet, Olivine, Phlogopite, Pyroxene and mineral content of Wackestone 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 Wackestone, 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, Wackestone is available in black, blue, brown, green, grey, orange, red, white, yellow colors. Appearance of Kimberlite is Dull and Banded and that of Wackestone is Rough and Dull. Properties of rock is another aspect for Kimberlite vs Wackestone. The hardness of Kimberlite is 6-7 and that of Wackestone is 2-3. The types of Kimberlite are Basaltic Kimberlites and Micaceous Kimberlites whereas types of Wackestone are Marl, Shale and Argillite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Kimberlite and Wackestone is white. The specific heat capacity of Kimberlite is 0.92 kJ/Kg K and that of Wackestone is 0.39 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 Wackestone is heat resistant, impact resistant.
