the highest rank of coal is anthracite, a hard black coal that burns with little flame and smoke, has the highest fixed-carbon content, 86–98 percent, and a heating value of 13,500–15,600 btu/lb (14.2–16.5 million joules/lb).
anthracite coal may be considered to be a transition stage between ordinary bituminous coal and graphite, produced by the more or less complete elimination of the volatile constituents of the former; and it is found most abundantly in areas that have been subjected to considerable earth-movements, such as the flanks of great mountain ranges. anthracite coal is a product of metamorphism and is associated with metamorphic rocks, just as bituminous coal is associated with sedimentary rocks.
