Coal is subdivided in terms of rank. The hardest form or highest rank is anthracite coal, which can be regarded as metamorphic rock because of later exposure to elevated temperature and pressure. Intermediate rank coal is bituminous and low rank coal includes lignite. http://en.wikipedia.org/wiki/Coalhttp://inspire.ec.europa.eu/codelist/CommodityCodeValue/anthracite2015-08-18 18:07 PM CEST2015-08-18 18:07 PM CESTanthraciteAnthracite is a hard, compact variety of mineral coal that has a high luster. It has the highest carbon content, the fewest impurities, and the highest calorific content of all types of coal (compared to bituminous coal and lignite). http://en.wikipedia.org/wiki/Anthracitehttp://inspire.ec.europa.eu/codelist/CommodityCodeValue/blackCoal2015-08-18 18:07 PM CEST2015-08-18 18:07 PM CESTblack coalBituminous coal or black coal is a moderately hard coal containing higher carbon and fewer impurities than lignite coal but of poorer quality than anthracite. Its coloration can be black or sometimes dark brown; often there are well-defined bands of bright and dull material within the seams. These distinctive sequences, which are classified according to either "dull, bright-banded" or "bright, dull-banded", is how bituminous coals are stratigraphically identified. - http://en.wikipedia.org/wiki/Black_coalhttp://inspire.ec.europa.eu/codelist/CommodityCodeValue/brownCoal2015-08-18 18:07 PM CEST2015-08-18 18:07 PM CESTbrown coalLignite, often referred to as sub-bituminous or brown coal, is a soft brown combustible sedimentary rock that is formed from naturally compressed peat. It is considered the lowest rank of coal due to its relatively low heat content. It is mined in Bulgaria, Kosovo, Greece, Germany, Poland, Serbia, Russia, Turkey, the United States, Canada, India, Australia and many other parts of Europe and it is used almost exclusively as a fuel for steam-electric power generation. 25.7% of Germany's electricity comes from lignite power plants, while in Greece lignite provides about 50% of its power needs. - http://en.wikipedia.org/wiki/Brown_coal
