- 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
- Lignite | Uses, Formation, Properties | Britannica
In many countries lignite is considered to be a brown coal Lignite contains about 60 to 70 percent carbon (on a dry, ash-free basis) and has a calorific value near 17 megajoules per kilogram (7,000 British thermal units per pound)
- What is Lignite? - Lignite Energy Council
Lignite is a dark brown to black combustible mineral formed over millions of years by the partial decomposition of plant material subject to increased pressure and temperature in an airless atmosphere In simple terms, lignite is coal

Lignite Coal Lignite is the lowest rank of coals Lignites are brown in color and have an earthy, crumbly texture They look more like dirt, than what people normally think of when they think of coal In the U S rank classification, lignites are defined based on calorific value
- Lignite - an overview | ScienceDirect Topics
Lignite is the least calorific of all categories of coal (anthracite, bituminous, subbituminous, brown coal lignite): this is due to its high moisture and volatile content and to its low carbon content
- 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

Lignite, often called brown coal, is a soft, brownish-black sedimentary rock that forms from naturally compressed peat It is considered the lowest rank of coal due to its relatively low heat content
- Lignite Coal: Uses, Benefits, and Energy Insights
Lignite is the lowest rank of coal due to its relatively low heat content and high moisture levels It forms from naturally compressed peat and is considered an intermediate stage between peat and sub-bituminous coal
