liptinite
Quick Summary
Liptinite is one of the three major groups of macerals, which are the microscopically recognizable organic constituents of coal. Liptinites are derived from the waxy or resinous parts of plants, such as cuticles, spores, and wound resins. They are characterized by a high hydrogen content and typically make up 5 to 15 percent of most coals. Varieties of liptinite include sporinite, cutinite, and resinite. Under ultraviolet light, liptinites may fluoresce, though this property diminishes with increasing coal rank.12

The vitrinite group is the most abundant, constituting as much as 50 to 90 percent of many North American coals. Vitrinites are derived primarily from cell walls and woody tissues. They show a wide range of reflectance values (how…
