The national coal resource assessment, being conducted by the US Geological Survey (USGS), provides information on both the quantity and quality of the coal beds and zones of the coals that are expected to provide most of the coal utilized in the US during the next few decades. As part of this assessment, the USGS developed comprehensive geochemical databases for the Pittsburgh and the Upper Freeport coal beds, which are then used to map and model trends in the ash yield, sulfur (S) content, and calorific value of the coals, as well as trends in selected major-, minor-, and trace- element contents. Compilation of the databases, mapping of geochemical trends, and comparisons of the trends and mean values for ash yield, S content, calorific value (Btu/lb), arsenic (As) content, selenium (Se) content, mercury (Hg) content, and chlorine (Cl) content for these beds are discussed in the paper. Final results for the complete database are presented for the Pittsburgh coal bed. Preliminary results for ash yield, S content and calorific value are presented for the Upper Freeport coal bed.
