资源简介：

This dataset is a point coverage of attributes on data location, thickness of the Fire Clay coal zone, and its elevation, in feet. 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. The file is also found as an ASCII Appendix of Chapter F, Disc 1 found elsewhere in Professional Paper 1625-C.
