摘要
褐煤是一种易燃的化石燃料,全世界的褐煤地质储量约为4×1012t,占全球煤炭储量的40%多。中国褐煤资源储量较少,只占煤炭资源总储量的8%。褐煤在中国主要形成于晚侏罗系-早白垩系地层,处于干旱-半干旱气候,规模较大、聚煤作用分布广泛,造煤植物由高等裸子植物的残体经长期的地质作用转化而成。详细探讨了褐煤资源及其形成条件。
Lignite is a flammable fossil fuel, whose geological reserve is 4×10^12 t approximately, accounting for more than 40% of global coal reserves.Lignite resource reserves fewer in China, accounted for only 8% of total reserves of coal resources. In Chi- na, lignite mostly formed in late Jurassic-Early Cretaceous strata, and in arid and semi-arid climate. Its scale is large, coal ac- cumulation is widely distributed, and coal-forming plants were transformed by the high gymnosperm residues in long-term geo- logical action. This paper investigated the lignite resources and its formation conditions.
