Formation

Formation
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.   
Charnockite is an intrusive igneous rock which is very hard and is formed due to weathering of existing rocks.
