Fire Clay Coal Zone County Statistics (Geology) in Virginia, Kentucky, and West Virginia
Description
This dataset is a polygon coverage of counties limited to the extent of
the Fire Clay coal zone resource areas and attributed with statistics on
the thickness of the Fire Clay coal bed, its elevation, and overburden
thickness, in feet. The file has been generalized from detailed geologic
coverages found elsewhere in Professional Paper 1625-C.
This resource model for the Fire Clay coal zone must be considered
provisional, because the correlation of the zone
continues to be evaluated in West Virginia.
