Definition
Carbonatite is intrusive or extrusive igneous rock which is defined by mineralogic composition, consisting of greater than 50 percent carbonate minerals
Metapelite is an old and currently not widely used field geological term for a clay rich fine-grained clastic sediment or sedimentary rock, i.e. mud or a mudstone

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.
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Metapelite is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.

Carbonatite vs Metapelite 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 Metapelite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Carbonatite and Properties of Metapelite. Learn more about Carbonatite vs Metapelite in the next section. The interior uses of Carbonatite include Decorative aggregates and Interior decoration whereas the interior uses of Metapelite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Carbonatite and Metapelite, 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 Metapelite include Cement manufacture, Construction aggregate, For road aggregate.
More about Carbonatite and Metapelite
Here you can know more about Carbonatite and Metapelite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Carbonatite and Metapelite consists of mineral content and compound content. The mineral content of Carbonatite includes Ancylite, Apatite, Barite, Fluorite, Magnetite, Natrolite, Sodalite and mineral content of Metapelite includes Albite, Chlorite, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Carbonatite vs Metapelite, 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, Metapelite is available in dark greenish - grey, green, light green, light greenish grey colors. Appearance of Carbonatite is Dull, Banded and Foilated and that of Metapelite is Banded. Properties of rock is another aspect for Carbonatite vs Metapelite. The hardness of Carbonatite is 3 and that of Metapelite is 5-6. The types of Carbonatite are Carbonatite whereas types of Metapelite are Metamorphic rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Carbonatite is white while that of Metapelite is . The specific heat capacity of Carbonatite is 0.51 kJ/Kg K and that of Metapelite is 0.72 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 Metapelite is heat resistant, impact resistant, pressure resistant.
