A variety of Coal

A carbon-poor and humidity-rich variety of coal which retains the structure of the original wood.
It is often referred to as brown coal, and is considered the lowest rank of coal (carbon content is only around 25-35%).

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.
