Lignite and Talc carbonate


Definition

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

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.

All about Talc carbonate and Lignite Properties

Know all about Talc carbonate and Lignite properties here. All properties of rocks are important as they define the type of rock and its application. Talc carbonate belongs to Metamorphic Rocks while Lignite belongs to Sedimentary Rocks.Texture of Talc carbonate is Very Soft whereas that of Lignite is Amorphous, Glassy. Talc carbonate appears Soft and Lignite appears Veined or Pebbled. The luster of Talc carbonate is pearly while that of Lignite is dull to vitreous to submetallic. Talc carbonate is available in colourless, grey, white colors whereas Lignite is available in black, brown, dark brown, grey, light to dark grey colors. The commercial uses of Talc carbonate are manufacturing of baby powder and that of Lignite are electricity generation.
