Anthracite. Specimens of anthracite coal, a hard, lustrous sedimentary rock derived from vegetable debris. Anthracite is a slow-burning, relatively smokeless fuel which gives out intense heat and is used in the production of coal gas, and in the iron, steel and synthetic rubber industries. It occurs in Paleozoic rocks (230-570 million years ago), in particular the Carboniferous of North America (Appalachian Mountains) and Europe, and the Permian of China, Siberia and Australia. This sample comes from south eastern British Columbia, Canada.
