vitrinite
Quick Summary
Vitrinite is a maceral group, which are microscopic organic constituents of coal. It is the principal maceral found in bright coal, known as vitrain. Vitrinite is derived from the woody plant tissue and cell walls of plants.12
Macerals are classified into three main groups: vitrinite, inertinite, and liptinite. Vitrinite typically makes up a large percentage of most coals, ranging from 50 to 90 percent. Vitrain, a component of coal with a glossy black luster, is primarily composed of vitrinite.23
