Definition
Carbonatite is intrusive or extrusive igneous rock which is defined by mineralogic composition, consisting of greater than 50 percent carbonate minerals

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.
Harzburgite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

Carbonatite vs Harzburgite 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 Harzburgite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Carbonatite and Properties of Harzburgite. Learn more about Carbonatite vs Harzburgite in the next section. The interior uses of Carbonatite include Decorative aggregates and Interior decoration whereas the interior uses of Harzburgite include Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Carbonatite and Harzburgite, 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 Harzburgite include As dimension stone, Cobblestones.
More about Carbonatite and Harzburgite
Here you can know more about Carbonatite and Harzburgite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Carbonatite and Harzburgite consists of mineral content and compound content. The mineral content of Carbonatite includes Ancylite, Apatite, Barite, Fluorite, Magnetite, Natrolite, Sodalite and mineral content of Harzburgite includes Amphibole, Chromite, Garnet, Magnesium, Olivine, Phlogopite, Plagioclase, Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Carbonatite vs Harzburgite, 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, Harzburgite is available in dark greenish - grey colors. Appearance of Carbonatite is Dull, Banded and Foilated and that of Harzburgite is Rough and Shiny. Properties of rock is another aspect for Carbonatite vs Harzburgite. The hardness of Carbonatite is 3 and that of Harzburgite is 5.5-6. The types of Carbonatite are Carbonatite whereas types of Harzburgite are Ultramafic rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Carbonatite and Harzburgite is white. The specific heat capacity of Carbonatite is 0.51 kJ/Kg K and that of Harzburgite is 1.25 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 Harzburgite is heat resistant, pressure resistant, wear resistant.
