Definition
Pantellerite is a peralkaline rhyolite. It has a higher iron and lower aluminium composition than comendite
Lignite is a soft brownish coal which shows traces of plants and is intermediate between bituminous coal and peat

Formation
Pantellerite 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.
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.
