5 Formation
5.1 Formation
Laterite is a type of sedimentary rock which is generally a reddish weathering product of basalt.
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.
