Rare earth elements in Pennsylvanian coals and shales in Indiana

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).

Coking coal of the United States: Modern and historical locations of coking coal mining locations and chemical, rheological, petrographic, and other data from modern samples

For the open-file report we collected new coking coal samples from Alabama, Kentucky, Oklahoma and Arkansas and analyzed them for proximate and ultimate analyses; calorific value; sulfur forms; major-, minor-, and trace-element abundances; free swelling indices; Gieseler plasticity; ASTM dilatation; coal petrography, and several other tests [air-dry loss (ADL), residual moisture (RM), equilibrium moisture (EQM), and true specific gravity (TSG)]. Coal Stability Factor (CSF) and Coal Strength after Reaction with CO2 (CSR) were predicted using chemical, rheological, and petrographic data (pCSF and pCSR, respectively). In addition, data from previously analyzed samples in Pennsylvania, West Virginia, Virginia, and Kentucky...
