Definition
During the impact melted material forming a breccia containing glass and crystal or lithic fragments together form Suevite rock.
Lignite is a soft brownish coal which shows traces of plants and is intermediate between bituminous coal and peat

Formation
Suevite is a metamorphic rock consisting partly of melted material, typically forming a breccia containing glass and crystal or lithic fragments, formed during an impact event.
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.
