Definition
Mylonite is a metamorphic rock formed by ductile deformation during intense shearing encountered during folding and faulting, a process termed cataclastic or dynamic metamorphism
Carbonatite is intrusive or extrusive igneous rock which is defined by mineralogic composition, consisting of greater than 50 percent carbonate minerals

Archaeological Significance
Formation
Mylonites are ductilely deformed rocks formed by the accumulation of large shear strain, in ductile fault zones.
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.

Mylonite vs Carbonatite 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. Mylonite vs Carbonatite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Mylonite and Properties of Carbonatite. Learn more about Mylonite vs Carbonatite in the next section. The interior uses of Mylonite include Decorative aggregates and Interior decoration whereas the interior uses of Carbonatite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Mylonite and Carbonatite, they have various applications in construction industry. The uses of Mylonite in construction industry include For road aggregate, Landscaping, Roadstone and that of Carbonatite 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 Mylonite and Carbonatite
Here you can know more about Mylonite and Carbonatite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Mylonite and Carbonatite consists of mineral content and compound content. The mineral content of Mylonite includes Porphyroblasts and mineral content of Carbonatite includes Ancylite, Apatite, Barite, Fluorite, Magnetite, Natrolite, Sodalite. You can also check out the list of all Metamorphic Rocks. When we have to compare Mylonite vs Carbonatite, the texture, color and appearance plays an important role in determining the type of rock. Mylonite is available in black to grey colors whereas, Carbonatite is available in black, brown, green, grey, pink, white colors. Appearance of Mylonite is Dull, Banded and Foilated and that of Carbonatite is Dull, Banded and Foilated. Properties of rock is another aspect for Mylonite vs Carbonatite. The hardness of Mylonite is 3-4 and that of Carbonatite is 3. The types of Mylonite are Blastomylonites, Ultramylonites and Phyllonites whereas types of Carbonatite are Carbonatite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Mylonite and Carbonatite is white. The specific heat capacity of Mylonite is 1.50 kJ/Kg K and that of Carbonatite is 0.51 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Mylonite is heat resistant, impact resistant, pressure resistant whereas Carbonatite is heat resistant, pressure resistant, water resistant.
