资源简介：
This dataset is a polygon coverage of counties limited to the extent of
the Fire Clay coal zone resource areas and attributed with remaining
resources (millions of short tons) in aggregated reporting categories as described
in USGS Circular 891. 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.
