Definition
Carbonatite is intrusive or extrusive igneous rock which is defined by mineralogic composition, consisting of greater than 50 percent carbonate minerals
Lignite is a soft brownish coal which shows traces of plants and is intermediate between bituminous coal and peat

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.
Coal formation takes place due to accumulation of plant debris in a swamp environment. The Coal formation process continues, as peat turns into lignite brown or black coal at increasing heat and pressure.

Carbonatite vs Lignite 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 Lignite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Carbonatite and Properties of Lignite. Learn more about Carbonatite vs Lignite in the next section. The interior uses of Carbonatite include Decorative aggregates and Interior decoration whereas the interior uses of Lignite include Not yet used. Due to some exceptional properties of Carbonatite and Lignite, 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 Lignite include For road aggregate, Steel production.
More about Carbonatite and Lignite
Here you can know more about Carbonatite and Lignite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Carbonatite and Lignite consists of mineral content and compound content. The mineral content of Carbonatite includes Ancylite, Apatite, Barite, Fluorite, Magnetite, Natrolite, Sodalite and mineral content of Lignite is not available. You can also check out the list of all Igneous Rocks. When we have to compare Carbonatite vs Lignite, 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, Lignite is available in black, brown, dark brown, grey, light to dark grey colors. Appearance of Carbonatite is Dull, Banded and Foilated and that of Lignite is Veined or Pebbled. Properties of rock is another aspect for Carbonatite vs Lignite. The hardness of Carbonatite is 3 and that of Lignite is 1. The types of Carbonatite are Not Available whereas types of Lignite are Xyloid Lignite or Fossil Wood and Compact Lignite or Perfect Lignite. 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 Lignite is black. The specific heat capacity of Carbonatite is Not Available and that of Lignite is 1.26 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 Lignite is heat resistant.
