What Are the Four Stages in Coal Formation?

The four stages in coal formation are peat, lignite, bituminous and anthracite. Each of these stages must be completed for coal to form. Stage one in coal production is peat. Peat is a fibrous substance that is oxidized by water and carbon dioxide. When a plant dies, and stays under water, it builds up an accumulation of peat.

Coal explained

Lignite contains 25%–35% carbon and has the lowest energy content of all coal ranks. Lignite coal deposits tend to be relatively young and were not subjected to extreme heat or pressure. Lignite is crumbly and has high moisture content, which contributes to its low heating value. Lignite accounted for 8% of total U.S. coal production in 2018.

What Coal Is

The kind of coal that was formed in North Dakota is called lignite. Lignite is a soft, crumbly coal with a high moisture content. It burns fast and does not give off as much heat as harder coals.

About the Coal Industry

Coal is by far Canada's most abundant fossil fuel, with 6.6 billion tonnes of recoverable coal reserves. Canada has anthracite, bituminous, sub-bituminous, and lignite coal deposits. More than 90% of Canada's coal deposits are located in western provinces, which provides a strategic advantage because of the close proximity of west coast ports.
