Coal Geology | Geoscience Australia

Anthracite, also known as hard coal, is a hard, compact variety of coal that has a submetallic luster.It has the highest carbon content, the fewest impurities, and the highest energy density of all types of coal and is the highest ranking of coals.. Anthracite is the most metamorphosed type of coal (but still represents low-grade metamorphism), in which the carbon content is between 86% and 98%.

Coal is a sedimentary rock made predominantly of carbon that can be burned for fuel. Coal is readily combustible, black or brownish-black, and has a composition that, including inherent moisture, consists of more than 50 percent by weight and more than 70 percent by volume of carbonaceous material. It is formed from plant remains that have been compacted, hardened, chemically
