Abstract
The Herrin (No. 11) coal in western Kentucky is normally a bright-banded, high-vitrinite, high-sulfur coal. Three sites have been found where the coal deviates from the expected appearance. In Union County, a site known only from a literature description, the upper two-thirds of the coal was described as a cannel. In Ohio County a thin, truncated section of the Herrin coal has a greater abundance of liptinite- and inertinite-rich microlithotypes towards the top of the seam. The various microlithotypes were frequently found in brecciated assemblages. In Hopkins County the Herrin coal was found to be largely a coarse breccia of oxidized macerals cemented by calcite. A marine limestone was present as a parting within the coal. Each occurrence represents the edge of the coal. The sites varied in the energy of the environment and perhaps also in proximity to marine waters.
