Abstract

This chart is one of a series that shows the regional characteristics of the Fire Clay coal zone. The maps and charts 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 this coal zone, the Fire Clay coal is the most economically important bed and is one of the leading producers in the state of Kentucky. The Fire Clay coal contains a flint-clay parting that is believed to be of volcanic origin. The widespread occurrence of this parting aids in correlation, and therefore the Fire Clay coal is a key marker bed in the region. This chart describes the distribution of data used for the coal assessment, generalized mined-out areas in relation to coal thickness, geologic structure of the bed, and coal-resource estimates. Coal thickness for the Fire Clay and Fire Clay rider beds is presented in Kentucky Geological Survey Map and Chart Series 5 (series 12).
