   11. <skos:note xml:lang="en">A relatively soft coal containing the tarlike substance asphaltic bitumen. Its carbon content is 60-80%, the rest composed of water, air, hydrogen, and sulfur. It is of higher quality than lignite coal but of poorer quality than anthracite. It was usually formed as a result of high pressure on lignite. It dark brown to black in color, commonly banded or layered. The major problem with burning of bituminous coal is air pollution.</skos:note>
