Definition

Lignite is a soft brownish coal which shows traces of plants and is intermediate between bituminous coal and peat

Mangerite is a plutonic intrusive igneous rock, which is essentially a hypersthene-bearing monzonite

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.

Mangerite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.
