This dataset is a point coverage of attributes on data location, thickness of the Upper Freeport coal bed, and its elevation, in feet. The file is also found as an ASCII Appendix of Chapter D, Disc 1 found elsewhere in Professional Paper 1625-C.
Categories: Data, pre-SM502.8; Types: Downloadable, Map Service, OGC WFS Layer, OGC WMS Layer, Shapefile; Tags: ALLEGANY County MD, ALLEGHENY County PA, ARMSTRONG County PA, ATHENS County OH, Appalachians, All tags...

This ARC/INFO point coverage represents the non-confidential, point- source stratigraphic data in Indiana that was used to map the structure and thickness maps of the Danville Coal for the National Coal Assessment.

These are shapefiles and final unioned polygon coverages used to calculate coal resources of the A through D coal zones, Yampa coal field, northwestern Colorado. Yamafing was used for the A coal zone, yambfing was used for the B coal zone, etc. Polygons that make up the final unioned polygons include counties, 7.5' quadrangles, townships, surface and coal ownership, leased areas, net coal thickness categories, and overburden categories. The final unioned coverage for each coal zone, was clipped by the resource boundary polygon of each coal zone. These polygons are described in the metadata files for the yam_bnd coverages.

These are shapefiles and ARC/INFO polygon coverages showing the isopachs of total net coal in beds greater than or equal to 1.2' thick for the A through G coal zones, Danforth Hills coal field. The coverage danathkg is the isopach coverage for the A coal zone; danbthkg is for the B coal zone, and so on.

This is a polygon coverage containing eleven different attributes of information including net coal thickness and estimated coal tonnages in the Calico and A-sequences in the Kaiparowits Plateau study area. This layer was derived from a "union" process, i.e., intersection and overlay of numerous layers and retaining attributes of each. It is the result of computing the geometric intersection of ten polygon coverages using the Environmental Systems Research Institute, Inc. (ESRI) Arc/Info UNION command, and finally calculating coal tonnage in INFO. Net coal thickness values are from 209 data points and represent all coal beds that are more than 1 foot thick.CARE SHOULD BE TAKEN IN USING THE COAL THICKNESS AND COAL...
This dataset is a polygon coverage of counties limited to the extent of the Fire Clay coal zone resource areas and attributed with original 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.

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.

These are shapefiles and ARC/INFO polygon coverages showing the isopachs of total net coal in beds greater than or equal to 1.2' thick for the A, B, C, and D coal zones in the Williams Fork Formation, Yampa coal field, northwestern Colorado. YAMATHKG is for the A coal zone, YAMBTHKG is for the B coal zone, etc.
This dataset is the digital compilation of geologic and resource maps provided mostly by State geologic surveys and depicts the projected area of occurrence of the Upper Freeport coal bed. The Upper Freeport coal bed is in Ohio, West Virginia, western Pennsylvania, and western Maryland. The coal bed may extend into eastern Kentucky, but correlations are highly uncertain and do not warrant extrapolation south of the areas shown on this map at this time. This dataset represents the extent of the Upper Freeport coal bed used in the Apalachian coal region assessment. The file has been generalized from detailed geologic coverages found elsewhere in Professional Paper 1625-C.

This dataset represents the thickness of the potentially minable Fire Clay coal benches in Virginia, West Virginia, and Kentucky. The coal zone is known by other names, depending upon locale. The data were comprised of values from Kentucky in EXCEL format, data searched from the USGS' NCRDS database for Virginia and entered into StratiFact, and a StratiFact database obtained from the West Virginia Geological and Economic Survey (WVGES). Point data were gridded, the grid contoured and imported to ARC/INFO as polygons. The Kentucky portion was replaced by a polygonal thickness coverage obtained from the Kentucky Geological Survey that had been manually contoured, therefore State line discrepancies are to be expected....

These are shapefiles and polygon coverages that contain numerous attributes of information on coal in the Calico and A-sequences of the Upper Cretaceous Straight Cliffs Formation in the Kaiparowits Plateau study area in southern Utah. These layers were derived from a "union" process of combining numerous polygon coverages using the Environmental Systems Research Institute, Inc. (ESRI) Arc/Info UNION command, and finally calculating coal tonnage in INFO. Net coal thickness values are from 209 data points and represent all coal beds that are more than 1 foot thick. The outside polygon defines the base of the coal-bearing Calico and A-sequences east of 112 degrees of longitude. The northern boundary is delineated by...

These are shapefiles and ARC/INFO polygon coverages showing the isopachs of total net coal in beds greater than or equal to 1 ft thick for the Cameo/Fairfield coal group and for the Cameo/Wheeler, South Canyon, and Coal Ridge coal zones, southern Piceance Basin coal assessment area. Also included are isopachs of total net coal in beds 1-2.3 ft thick, 2.3-3.5, 3.5-7.0, and 7.0-14, and greater than 14 ft thick in the Cameo/Wheeler coal zone.
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.
