Definition
Conglomerate is a sedimentary rock which forms from rounded gravel and boulder sized clasts which are cemented together in a matrix
Kimberlite is a rare, blue-tinged, coarse-grained intrusive igneous rock, which sometimes contains diamonds and is mostly found in South Africa and Siberia.
Origin

Kimberley, South Africa

Etymology
From Latin conglomeratus, to roll together, i.e. from com together + glomerare to gather into a ball, from glomus (genitive glomeris) a ball
From Kimberley + -ite, from the name of the South African town of Kimberley where the rock was first found.

Archaeological Significance
Formation
Conglomerate forms where sediments consisting mainly of pebble and cobble-size clasts at least two millimeters in diameter starts accumulating.
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.

Conglomerate vs Kimberlite 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. Conglomerate vs Kimberlite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Conglomerate and Properties of Kimberlite. Learn more about Conglomerate vs Kimberlite in the next section. The interior uses of Conglomerate include Decorative aggregates, Floor tiles and Homes whereas the interior uses of Kimberlite include Countertops, Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Conglomerate and Kimberlite, they have various applications in construction industry. The uses of Conglomerate in construction industry include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Roadstone and that of Kimberlite 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 Conglomerate and Kimberlite
Here you can know more about Conglomerate and Kimberlite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Conglomerate and Kimberlite consists of mineral content and compound content. The mineral content of Conglomerate includes Clay, Sand, Silica, Silt and mineral content of Kimberlite includes Garnet, Olivine, Phlogopite, Pyroxene. You can also check out the list of all Sedimentary Rocks. When we have to compare Conglomerate vs Kimberlite, the texture, color and appearance plays an important role in determining the type of rock. Conglomerate is available in beige, black, brown, buff, light to dark grey, orange, rust, white, yellow colors whereas, Kimberlite is available in black, bluish - grey, brown, dark greenish - grey, green, grey colors. Appearance of Conglomerate is Shiny and Rounded and that of Kimberlite is Dull and Banded. Properties of rock is another aspect for Conglomerate vs Kimberlite. The hardness of Conglomerate is 2-3 and that of Kimberlite is 6-7. The types of Conglomerate are Orthoconglomerate and Paraconglomerate whereas types of Kimberlite are Basaltic Kimberlites and Micaceous Kimberlites. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Conglomerate and Kimberlite is white. The specific heat capacity of Conglomerate is 0.92 kJ/Kg K and that of Kimberlite 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.Conglomerate is heat resistant whereas Kimberlite is heat resistant, impact resistant.
