Pocahontas No. 3 Coal Bed County Statistics (Chemistry) in West Virginia and Virginia

This dataset is a polygon coverage of counties limited to the extent of
the Pocahontas No. 3 coal bed resource areas and attributed with
statistics on these coal quality parameters: ash yield (percent), sulfur
(percent), SO2 (lbs per million Btu), calorific value (Btu/lb), arsenic
(ppm) content and mercury (ppm) content. The file has been generalized
from detailed geologic coverages found elsewhere in Professional Paper
1625-C. The attributes were generated from public data found in the
geochemical dataset found in Chap. H, Appendix 2, Disc 1. Please see
the metadata file found in Chap. H, Appendix 3, Disc 1, for more
detailed information on the geochemical attributes. The county
statistical data used for this data set are found in Tables 6-9 and
21-22 in Chap. H, Disc 1. Additional county geochemical statistics for
other parameters are found in Tables 10-20, Chap. H, Disc 1.
