Archaeological Significance
Formation
Carbonatites are intrusive or extrusive igneous rocks which are defined by mineralogic composition consisting of greater than 50 percent carbonate minerals and are formed due to low degrees of partial melting of rocks.
Charnockite is an intrusive igneous rock which is very hard and is formed due to weathering of existing rocks.

Carbonatite vs Charnockite 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. Carbonatite vs Charnockite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Carbonatite and Properties of Charnockite. Learn more about Carbonatite vs Charnockite in the next section. The interior uses of Carbonatite include Decorative aggregates and Interior decoration whereas the interior uses of Charnockite include Bathrooms, Countertops, Decorative aggregates, Entryways, Floor tiles, Homes, Hotels, Kitchens and Stair treads. Due to some exceptional properties of Carbonatite and Charnockite, they have various applications in construction industry. The uses of Carbonatite 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 Charnockite include As dimension stone.
More about Carbonatite and Charnockite
Here you can know more about Carbonatite and Charnockite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Carbonatite and Charnockite consists of mineral content and compound content. The mineral content of Carbonatite includes Ancylite, Apatite, Barite, Fluorite, Magnetite, Natrolite, Sodalite and mineral content of Charnockite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Olivine, Plagioclase, Pyroxene, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Carbonatite vs Charnockite, the texture, color and appearance plays an important role in determining the type of rock. Carbonatite is available in black, brown, green, grey, pink, white colors whereas, Charnockite is available in black, grey, orange, pink, white colors. Appearance of Carbonatite is Dull, Banded and Foilated and that of Charnockite is Veined or Pebbled. Properties of rock is another aspect for Carbonatite vs Charnockite. The hardness of Carbonatite is 3 and that of Charnockite is 6-7. The types of Carbonatite are Carbonatite whereas types of Charnockite are Enderbite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Carbonatite and Charnockite is white. The specific heat capacity of Carbonatite is 0.51 kJ/Kg K and that of Charnockite is 0.84 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Carbonatite is heat resistant, pressure resistant, water resistant whereas Charnockite is heat resistant, wear resistant.
