Suevite and Lignite
Definition
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
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.

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