资源简介:
This dataset (located by latitude and longitude) is a subset of the
geochemical dataset found in Chap. E, Appendix 2, Disc 1, and used
in this study of the Lower Kittanning coal bed. 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), The
Pennsylvania State University (PSU), the West Virginia Economic and
Geological Survey (WVGES), and the Ohio Division of Geological Survey
(OHGS) coal quality databases as well as published U.S. Bureau of Mines
(USBM) data. The metadata file for the complete dataset is found in
Chap. E, Appendix 3, Disc 1 (please see it for more detailed
information on this geochemical dataset). This subset of the geochemical
data for the Lower Kittanning coal bed 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. E,
Appendix 4, 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.
