Map and Chart--KGS


This map is one of a series that shows the regional characteristics of the Fire Clay coal zone. The maps were prepared as part of the U.S. Geological Survey's National Coal Assessment Program, which compiles regional maps and databases that provide a comprehensive assessment of the most important coal beds in the nation. Within the zone, the Fire Clay coal is the most economically important bed and is one of the leading producers in the state of Kentucky. It is known for a persistent flint-clay parting that is believed to be of volcanic origin. This map represents the total coal thickness, minus partings, of the Fire Clay and Fire Clay rider coals for the eastern Kentucky region.
