- Lignite - Wikipedia
Lignite (derived from Latin lignum meaning 'wood'), often referred to as brown coal, [1] is a soft, brown, combustible sedimentary rock formed from naturally compressed peat It has a carbon content around 25–35% [ 1 ] [ 2 ] and is considered the lowest rank of coal due to its relatively low heat content

Lignite, generally yellow to dark brown or rarely black coal that formed from peat at shallow depths and temperatures lower than 100 °C (212 °F) It is the first product of coalification and is intermediate between peat and subbituminous coal according to the coal classification used in the United

- Lignite - Energy Education
Lignite is the first "stage" of coal that forms after sediment piles on top of layers of peat, which gets heated and compressed Since lignite has a lower carbon content and has not been buried very long, it does not have as high an energy density as harder black coals
