The stratigraphic and regional variation of petrographic and chemical properties within the coals of the Upper Carboniferous Tradewater Formation and surrounding rocks in the Western Kentucky coal field were analyzed with the intent of constructing a

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 descrip

The relationship between Hardgrove grindability and coal microlithotype composition was studied for three coals from two eastern Kentucky mines. The purpose of the study was to further investigate the use of petrographic data as a predictor of mechan

A depositional model for the coals of the Tradewater Formation and associated rock units was constructed as a predictive device for the occurrence of economically important low sulfur coal. Twenty-one cores were examined and ninety-eight coal samples

The project Petrographic Characterization of Kentucky Coals consists of research in three specific areas of coal petrology: spectral fluorescence of liptinite macerals, properties of semi-inert macerals, and size/form/microlithotype association of py
