telinite

Telinite is a type of maceral, which is a microscopically recognizable organic constituent of coal. Macerals are analogous to minerals in inorganic rocks but lack a definite crystalline structure. They are essentially coalified plant remains that change chemically and physically as the rank of coal increases.1

Telinite is a subtype of vitrinite, one of the three major maceral groups. Vitrinite is derived from cell walls and woody plant tissue. Telinite specifically refers to the brighter parts of vitrinite that form cell walls. Vitrinites are the most abundant macerals in most coals, typically making up 50 to 90 percent of the material.12
