(1) Perhaps the hydrothermal activity served as the impetus for the enhancement of coal rank from lignite or subbituminous to high volatile A bituminous.(2) The principal crops are wheat, maize, barley, sugar beet, potatoes, and grapes, while mineral resources include bauxite, brown coal, lignite , and copper.(3) Europe, for instance, has sufficient amounts of brown coal, or lignite , to keep the continent supplied with electrical power for the next 200 years or so.(4) Repeatedly, descriptions of lignite , which may be associated with floodplain sequences, are reported.(5) It is overlain by the lower shale member, which consists of interbedded carbonaceous shale and lignite that accumulated in coastal marsh and swamps landward of the shoreline.(6) In the lower third of the unit, a conspicuous 15-40 cm thick lignite with quartz grit matrix occurs and includes plant stem fragments, some more than 5 cm long.(7) Peats will in situ change successively to lignite , to bituminous coal, and eventually to anthracite.(8) Mining is focused on lignite , bauxite, asbestos, and marble.(9) That plant burned lignite to raise steam for the compressors.(10) Germany's chief natural resources are iron ore, bituminous coal and lignite, potash, timber, lignite , natural gas, salt, and nickel.(11) The sediments include lacustrine freshwater limestones, silts, marls, occasional sands and local lignite .(12) The republic has supplies of coal and lignite (brown coal) and uranium ore.(13) Depending on the degree of carbon concentration and coalification, one differentiates between lignite , bituminous coal and anthracite.(14) Rice husks release about 16 joules of energy per kilogram, about the same as lignite but less than bituminous coal's 25 joules.(15) Coal is usually classified into the sub-groups known as anthracite, bituminous, lignite , and peat.(16) The plant burns lignite coal from the Maritsa Iztok mining complex and produces a large amount of sulphur dioxide.
