Notes c d e f   g
aSource: Robert Finkelman (personal commun., 1987).
bConcentration ranges observed for more than 280 coal ashes analyzed by AAS in U.S. Geological Survey laboratories.
cCorrelation with Zn is 0.93.
dHigh values in special mineral samples.
eVariable concentrations; probably dependent on water contact.
fWide range in lithotypes.
gConcentration is very high near ore beds.
