Initially the peat is converted into lignite or ''brown coal'' these are coaltypes with low organic maturity. In comparison to other coals, lignite is quite soft and its colour can range from dark black to various shades of brown.
Data on world coal resources are compiled and aggregated under two classification systems. In Australia, the term ''black coal'' includes anthracite, bituminous and subbituminous coal and the term ''brown coal'' refers to lignite.
Publisher Summary. This chapter discusses physical structure and properties of brown coal.

Coal is a readily combustible rock containing more than 50 percent by weight of carbonaceous material formed from compaction and indurations of variously altered plant remains similar to those in peat.. After a considerable amount of time, heat, and burial pressure, it is metamorphosed from peat to lignite.
Bituminous coal appears shiny and smooth when you first see it, but look closer and you may see it has layers. Subbituminous: Subbituminous coal is black in color and dull (not shiny), and has a higher heating value than lignite. Lignite: Lignite coal, aka brown coal, is the lowest grade coal with the least concentration of carbon.
Lignite, often referred to as brown coal, is a soft, brown, combustible, sedimentary rock formed from naturally compressed is considered the lowest rank of coal due to its relatively low heat has a carbon content around 2035% percent.
