Zirconium averaged 24.32 ppm (± 20.59 ppm) in West Virginia coals with a histogram skewed toward low values and tailing toward high values and a maximum value of 146.22 ppm in the No. 6 Block coal.  Zirconium correlated with slightly with ash yield and the ash related elements niobium (Nb), thorium (Th), chromium (Cr), neodymium (Nd), vanadium (V), hafnium (Hf), tantalum (Ta), lithium (Li), tin (Sn), lead (Pb), scandium (Sc), yttrium (Y) and gallium (Ga) and with rare earth element components in the mineral monazite, especially cerium (Ce), lanthanum (La), dysprosium (Dy), erbium (Er) and gadolinium (Gd).
