Influence of regional structure on the development and quality of the Upper Elkhorn no. 2 coal bed, eastern Kentucky

The Upper Elkhorn No. 2 coal bed (Middle Pennsylvanian Breathitt Formation) in eastern Kentucky exhibits thickness and coal quality trends which suggest that peat deposition was contemporaneous with tectonism. The coal thickens and has high vitrinite and low ash and sulfur content the Belfry anticline in Pike Country. T in the vicinity of the Floyd Country channel, a basement trough. In both cases other Pennsylvanian coals exhibit similar trends, suggesting that the penecontemporaneous tectonism persisted at least through a portion of the Carboniferous.
