<https://data.amerigeoss.org/dataset/1b8825e0-5b74-4f27-b732-99fbeadfc8e9> a dcat:Dataset ;
    dct:description """This dataset (located by latitude and longitude) is a subset of the
geochemical dataset found in Chap. F, Appendix 7, Disc 1, and used
in this study of the Fire Clay coal zone. That dataset is a
compilation of data from the U.S. Geological Survey's (USGS) National
Coal Resources Data System (NCRDS) USCHEM (U.S. geoCHEMical), and the
Kentucky Geological Survey (KGS) Kentucky Coal Resources Information
System (KCRIS) databases. The metadata file for the complete dataset is
found in Chap. F, Appendix 8, Disc 1 (please see it for more
detailed information on this geochemical dataset). This subset of the
geochemical data for the Fire Clay coal zone includes ash yield, sulfur
content, SO2 value, gross calorific value, arsenic content and mercury
content for these records, as well as the ranking of these values, which
is described later under the attributes in this metadata file.
Analytical techniques are described in the references in Chap. F,
Appendix 9, Disc 1. The analytical data are stored as text fields
because many of the parameters contain letter qualifiers appearing after
the numerical data values. The following is a list of the possible
qualifier values: L - less than, G - greater than, N - not detected, or
H - interference that cannot be easily resolved. Not all of these codes
may be in this database.""" ;
