Definition
Carbonatite is intrusive or extrusive igneous rock which is defined by mineralogic composition, consisting of greater than 50 percent carbonate minerals
Syenite is a coarse-grained igneous rock which is composed mainly of alkali feldspar and various ferromagnesian 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.
Syenites are formed due to alkaline igneous activities and are generally formed in thick continental crustal areas or in Cordilleran subduction zones.

Carbonatite vs Syenite 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 Syenite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Carbonatite and Properties of Syenite. Learn more about Carbonatite vs Syenite in the next section. The interior uses of Carbonatite include Decorative aggregates and Interior decoration whereas the interior uses of Syenite include Flooring, Homes, Hotels and Interior decoration. Due to some exceptional properties of Carbonatite and Syenite, 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 Syenite include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Landscaping, Making natural cement, Manufacture of magnesium and dolomite refractories.
More about Carbonatite and Syenite
Here you can know more about Carbonatite and Syenite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Carbonatite and Syenite consists of mineral content and compound content. The mineral content of Carbonatite includes Ancylite, Apatite, Barite, Fluorite, Magnetite, Natrolite, Sodalite and mineral content of Syenite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Pyroxene, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Carbonatite vs Syenite, 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, Syenite is available in brown, buff, cream, green, grey, pink, white colors. Appearance of Carbonatite is Dull, Banded and Foilated and that of Syenite is Banded and Foilated. Properties of rock is another aspect for Carbonatite vs Syenite. The hardness of Carbonatite is 3 and that of Syenite is 5.5-6. The types of Carbonatite are Carbonatite whereas types of Syenite are Shonkinite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Carbonatite and Syenite is white. The specific heat capacity of Carbonatite is 0.51 kJ/Kg K and that of Syenite 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 Syenite is heat resistant, impact resistant, wear resistant.
