Samarium averaged 1.52 ppm (± 0.86 ppm) in West Virginia coals with a near normal histogram showing a slight tail toward higher values and a maximum value of 8.30 ppm in a bench of the Coalburg coal.  Samarium correlated slightly with ash yield, and correlated very well with some other rare earth element components of monazite, especially lanthanum (La), europium (Eu), cerium (Ce), lutetium (Lu), ytterbium (Yb) and terbium (Tb).  Samarium also correlated well with the ash related elements thorium (Th), scandium (Sc), chromium (Cr), vanadium (V), lithium (Li), hafnium (Hf) and  lead (Pb).
