Definition
Carbonatite is intrusive or extrusive igneous rock which is defined by mineralogic composition, consisting of greater than 50 percent carbonate minerals
  
Argillites are highly compact sedimentary or slightly metamorphosed rocks that consist largely or wholly of particles of clay or silt but lack the fissility of shale or the cleavage characteristic of slate

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.
  
An argillite is a fine-grained sedimentary rock mainly composed of clay particles which forms from lithified muds which contain variable amounts of silt-sized particles.

Carbonatite vs Argillite 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 Argillite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Carbonatite and Properties of Argillite. Learn more about Carbonatite vs Argillite in the next section. The interior uses of Carbonatite include Decorative aggregates and Interior decoration whereas the interior uses of Argillite include Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Carbonatite and Argillite, 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, Unknown, Unknown and that of Argillite include Used for flooring, stair treads, borders and window sills..
More about Carbonatite and Argillite
Here you can know more about Carbonatite and Argillite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Carbonatite and Argillite consists of mineral content and compound content. The mineral content of Carbonatite includes Ancylite, Apatite, Barite, Fluorite, Magnetite, Natrolite, Sodalite and mineral content of Argillite includes Biotite, Chlorite, Feldspar, Micas, Muscovite or Illite, Plagioclase, Pyrite, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Carbonatite vs Argillite, the texture, color and appearance plays an important role in determining the type of rock. Carbonatite is available in black, brown, colourless, green, grey, pink, white colors whereas, Argillite is available in dark grey to black, pink, red, white colors. Appearance of Carbonatite is Dull, Banded and Foilated and that of Argillite is Rough and Dull. Properties of rock is another aspect for Carbonatite vs Argillite. The hardness of Carbonatite is 3 and that of Argillite is 2-3. The types of Carbonatite are Not Available whereas types of Argillite are Not Available. 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 Argillite is white to grey. The specific heat capacity of Carbonatite is Not Available and that of Argillite is 0.87 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 Argillite is heat resistant, impact resistant.
