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

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.
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.

All about Lignite and Suevite Properties
Know all about Lignite and Suevite properties here. All properties of rocks are important as they define the type of rock and its application. Lignite belongs to Sedimentary Rocks while Suevite belongs to Metamorphic Rocks.Texture of Lignite is Amorphous, Glassy whereas that of Suevite is Earthy. Lignite appears Veined or Pebbled and Suevite appears Banded. The luster of Lignite is dull to vitreous to submetallic while that of Suevite is earthy. Lignite is available in black, brown, dark brown, grey, light to dark grey colors whereas Suevite is available in black, brown, colourless, green, grey, pink colors. The commercial uses of Lignite are electricity generation and that of Suevite are as a feed additive for livestock, gemstone, metallurgical flux, source of magnesia (mgo).
