Lignite an overview ScienceDirect Topics
Lignite, often referred to as brown coal, is a soft brown combustible sedimentary rock that is formed from naturally compressed peat. It is considered the lowest rank of coal due to its relatively low heat content. It is mined in China, Bulgaria, Greece, Germany, Kosovo, Poland, Serbia, Russia, Turkey, the United States, Canada, India
Lignite Rock History Origin Compare Nature
Lignite is a soft brownish coal which shows traces of plants and is intermediate between bituminous coal and peat. Lignite is available in black, brown, dark brown, grey, light to dark grey colors. The streak of a rock is the color of powder produced when it is dragged across an unweathered surface.
Lignite: Mineral information, data and localities.
Lignite can be separated into two types. The first is xyloid lignite or fossil wood and the second form is the compact lignite or perfect lignite. Lignite is geologically younger than higher-grade coals, originating mainly in the Tertiary period.
lignite coal Britannica
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 States and Canada.In many countries lignite is considered to be a brown coal.

The term diagenesis was used by Tissot and Welte (1984) for the initial stages of coalification but it has also been used for the entire coalification process.

What are the types of coal? USGS
Lignite: Lignite coal, aka brown coal, is the lowest grade coal with the least concentration of carbon. Lignite has a low heating value and a high moisture content and is mainly used in electricity generation. The precursor to coal is peat. Peat is a soft, organic material
