TL;DR: In this article, an inductively coupled plasma-mass spectroscopy (ICP-MS) analysis of the tonstein and underlying coal collected from four sites in eastern Kentucky was performed.

TL;DR: The coal type refers solely to coals' depositional origin and the maceral-mineral admixture resulting from that origin, whereas coal rank refers to the changes in geochemistry and resultant changes in reflectance caused by increasing thermal maturity of the coal.

TL;DR: Peat depositional environments, the sites where and conditions under which peat accumulates, significantly influence a resultant coal's physical properties, chemical composition, and coal utilization behavior.

TL;DR: In this paper, coalbed gases and waters from exploratory and production gas wells in the southeastern Illinois Basin were sampled to assess geochemically the origin of coal-bed gases, with an emphasis on the Springfield and Seelyville coal Members that are commercially targeted for coalbed methane production in Indiana.

TL;DR: In this paper, four eastern Kentucky Pennsylvanian coals (from oldest to youngest, the Manchester, Pond Creek, Fire Clay, and Hazard coals) were examined for their total rare earth element (REY) concentration and the possible mechanisms for enrichment of the rare earths.
