Definition
Carbonatite is intrusive or extrusive igneous rock which is defined by mineralogic composition, consisting of greater than 50 percent carbonate minerals
Laterite rock is a type of Sedimentary rock which is rich in iron and aluminium, formed in hot and wet tropical areas

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.
Laterite is a type of sedimentary rock which is generally a reddish weathering product of basalt.

Carbonatite vs Laterite 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 Laterite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Carbonatite and Properties of Laterite. Learn more about Carbonatite vs Laterite in the next section. The interior uses of Carbonatite include Decorative aggregates and Interior decoration whereas the interior uses of Laterite include Decorative aggregates, Flooring and Interior decoration. Due to some exceptional properties of Carbonatite and Laterite, 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 Laterite include Cobblestones, For road aggregate, Landscaping, Roadstone.
More about Carbonatite and Laterite
Here you can know more about Carbonatite and Laterite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Carbonatite and Laterite consists of mineral content and compound content. The mineral content of Carbonatite includes Ancylite, Apatite, Barite, Fluorite, Magnetite, Natrolite, Sodalite and mineral content of Laterite includes Aluminum Oxides, Biotite, Hematite, Hornblade, Iron Oxides, Manganese Oxides, Micas, Muscovite or Illite, Plagioclase, Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Carbonatite vs Laterite, 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, Laterite is available in brown, buff, red colors. Appearance of Carbonatite is Dull, Banded and Foilated and that of Laterite is Rough and Banded. Properties of rock is another aspect for Carbonatite vs Laterite. The hardness of Carbonatite is 3 and that of Laterite is 2. The types of Carbonatite are Carbonatite whereas types of Laterite are Laterite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Carbonatite and Laterite is white. The specific heat capacity of Carbonatite is 0.51 kJ/Kg K and that of Laterite 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.Carbonatite is heat resistant, pressure resistant, water resistant whereas Laterite is heat resistant, pressure resistant.
