Coal includes anthracite, bituminous coal, lignite, and peat. Australian coal deposits include both lignite (brown coal) and black coal. The region is abundant in fossil fuels including natural gas, crude oil and lignite coal. Montan wax is a fossilized wax extracted from coal and lignite. However, lignite coal is the lowest grade coal. These mineral resources include billions of tons of lignite coal. Substantial deposits of bituminous, subbituminous, and lignite coal are found in the state. Scientists sought new ways to produce liquid fuels from bitumen, coal, andf lignite. It is most commonly used to mine coal and lignite (brown coal). It is of higher quality than lignite coal but of poorer quality than anthracite. Some tests involve co-pyrolysis of oil shale with lignite and cellulose wastes. Almost all coal burnt in power stations is either local lignite or imported hardcoal. The same process is responsible for the formation of fossil fuels like lignite or coal. The estimated total reserves of lignite coal that month was . Germany is rich in timber, lignite, potash and salt.
