Bench samples from the Springfield (western Kentucky No. 9) coal bed have been analyzed for 25 major, minor, and trace elements, including Au and Pt, by instrumental and radiochemical neutron activation analyses. The elemental enrichment trend of this coal bed, compared with crustal abundances, is similar to the Pittsburgh coal bed. Except for Mn, all the other elements in the western Kentucky No. 9 coal have a larger or comparable range of variation when compared with the Pittsburgh bed. The coefficients of variation increase with decreasing concentrations, or remain constant and independent of concentrations. They could be used in evaluating...
