Inductively coupled plasma - optical emission spectrometry (ICP-OES) analysis data compiled using sample preparation procedures outlined by ASTM D2013/D2013M-18 and ASTM D6357, and using two independent sets of element standards for instrument calibration. Additional analysis methodologies are described in detail in the resulting publication Rare earth elements and yttrium in Pennsylvanian coals and shales in the eastern part of the Illinois Basin (Mastalerz et al., 2020).
Shapefiles showing the extent of the Dugger, Minshall-Buffaloville, Seelyville, and Springfield Coal Members derived from coal-test records, mine-map notation, and interpretations of geophysical logs. Information was included in the USGS National Coal Resources Data System (NCRDS).
