Macerals. Some of the macerals are the same for lowrank lignite coals, but there are different maceral groups and additional macerals for lignites. Liptinites are derived from spores, pollens, cuticles, and resins in the original plant material. These plant parts are more hydrogenrich than other macerals. They are also fluorescent at some coal ranks.
