Definition
Talc carbonate is nothing but a rock sequence or a mineral composition found in metamorphic ultramafic rocks.
Lignite is a soft brownish coal which shows traces of plants and is intermediate between bituminous coal and peat

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

Talc carbonate 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. Talc carbonate vs Lignite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Talc carbonate and Properties of Lignite. Learn more about Talc carbonate vs Lignite in the next section. The interior uses of Talc carbonate include Decorative aggregates and Interior decoration whereas the interior uses of Lignite include Not yet used. Due to some exceptional properties of Talc carbonate and Lignite, they have various applications in construction industry. The uses of Talc carbonate in construction industry include Source of calcium and that of Lignite include For road aggregate, Steel production.
More about Talc carbonate and Lignite
Here you can know more about Talc carbonate and Lignite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Talc carbonate and Lignite consists of mineral content and compound content. The mineral content of Talc carbonate includes Carbonate, Chlorite, Magnesium and mineral content of Lignite is not available. You can also check out the list of all Metamorphic Rocks. When we have to compare Talc carbonate vs Lignite, the texture, color and appearance plays an important role in determining the type of rock. Talc carbonate is available in colourless, grey, white colors whereas, Lignite is available in black, brown, dark brown, grey, light to dark grey colors. Appearance of Talc carbonate is Soft and that of Lignite is Veined or Pebbled. Properties of rock is another aspect for Talc carbonate vs Lignite. The hardness of Talc carbonate is 1-2 and that of Lignite is 1. The types of Talc carbonate 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 Talc carbonate is white while that of Lignite is black. The specific heat capacity of Talc carbonate is 0.92 kJ/Kg K 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.Talc carbonate is heat resistant, wear resistant whereas Lignite is heat resistant.
