Terbium averaged 0.26 ppm (± 0.15 ppm) in West Virginia coals with a near normal histogram showing a slight tail toward higher values and a maximum value of 1.26 ppm in a bench of the Coalburg coal.  Terbium did not correlate with ash yield.  Terbium is one of the rare earth elements and correlated well with other rare earth elements such as europium (Eu), samarium (Sm), ytterbium (Yb), lutetium (Lu), scandium (Sc), cerium (Ce), thorium (Th), lanthanum (La) and lead (Pb).
