- a brown carbonaceous sedimentary rock with woody texture that consists of accumulated layers of partially decomposed vegetation: used as a fuel. Fixed carbon content: 46–60 per cent; calorific value: 1.28 × 10 7 to 1.93 × 10 7 J/kg (5500 to 8300 Btu/lb)Also called: brown coal
Word Origin and History for lignite
"imperfectly formed coal," 1808, from French, from Latin lignum "wood" (see ligni-). Brown coal that still shows traces of the wood it once was. Probably directly from Lithanthrax Lignius, name given to woody coal by Swedish chemist Johan Gottschalk Wallerius (1709-1785) in 1775.
- A soft, brownish-black form of coal having more carbon than peat but less carbon than bituminous coal. Lignite is easy to mine but does not burn as well as other forms of coal. It is a greater polluter than bituminous coal because it has a higher sulphur content. Compare anthracite bituminous coal.
