This dataset is a polygon coverage of the Fire Clay coal zone that represents the areas in which resources were calculated and is only part of the full outcrop of the coal zone. Parts of the boundaries of the resource areas represent the 14-inch thickness isoline of the Fre Clay coal or the sub-crop limits of data availability; other parts of the boundaries are actual outcrop. 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 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.

The base of the Pittsburgh Coal bed and its stratigraphically (non-coal) equivalent horizon is used to subdivide Upper Pennsylvanian Series strata into the overlying Monongahela Group and the underlying Conemaugh Group in the Appalachian Basin coal region. This dataset depicts areas in which Pittsburgh coal resources were calculated and was obtained largely from published maps. Because different coal thickness criteria were used to delineate the line denoting known resources in Ohio versus West Virginia, an offset is observed at the State boundaries. This dataset is a polygon coverage of counties limited to the extent of the Pittsburgh coal bed resource areas. The file has been generalized from detailed coverages...

This dataset is a polygon coverage of the resource areas of the Lower Kittanning coal zone. The polygons are subdivided into 2 categories: resource areas inside the outcrop, and areas either too thin, outside the outcrop, or beyond data collection limits. The coal zone must contain at least 14 inches of coal to be a resource. This spatial data set of the Lower Kittanning coal bed and known mined areas is one of many Geographic Information System (GIS) products of the National Coal Assessment that is being conducted by the U.S. Geological Survey in cooperation with State geological surveys and other Federal and State agencies. The Lower Kittanning coal bed is an important economic coal in the northern part of the...

This dataset is a polygon coverage of minable thickness for the Pond Creek coal zone in Kentucky, West Virginia, and Virginia. The coverage was created by gridding 4,391 points and contouring the grid with 1.17-ft intervals. The polygons have elevation values halfway between the bounding contour arc values. This dataset honors data submitted for the asessment from the Kentucky Geological Survey; therefore contour lines may not match across State lines (see Process Steps). This map is one of many Geographic Information System (GIS) products of the National Coal Assessment that is being conducted by the U.S. Geological Survey in cooperation with State geological surveys and other Federal and State agencies.

This dataset is a polygon coverage of the mined areas of the Pocahontas No. 3 coal bed. The polygons are subdivided into 3 categories. These categories are areas where resources are mined underground, areas where resources are mined on the surface, and areas where resources are not mined. This map is one of many Geographic Information System (GIS) products of the National Coal Assessment that is being conducted by the U.S. Geological Survey in cooperation with State geological surveys and other Federal and State agencies. The Pocahontas No. 3 coal bed occurs within the Pocahontas Formation (Lower Pennsylvanian) and underlies all or parts of Wyoming, McDowell, Raleigh, Summers, Mercer, Greenbrier, Logan, and Mingo...

The Edwards aquifer is a karst aquifer system that is a primary water source for a large part of central Texas including the city of San Antonio, Texas. These vector geospatial data represent the geographic extent of the contributing zones for the Northern, Barton Springs, and San Antonio segments of the Edwards aquifer. The contributing zone is defined as the drainage area of the Edwards Plateau that contributes surface water to the Edwards aquifer recharge zone. The recharge zone is where surface water and precipitation infiltrate into the outcrop of the rocks that compose the aquifer (see Ashworth and Hopkins, 1995, and George and others, 2011). References Ashworth, J.B., and Hopkins, Janie, 1995, Aquifers of...

This dataset is a polygon coverage of counties limited to the extent of the Lower Kittanning coal bed resource areas and attributed with statistics on these coal quality parameters: ash yield (percent), sulfur (percent), SO2 (lbs per million Btu), calorific value (Btu/lb), arsenic (ppm) content and mercury (ppm) content. The file has been generalized from detailed geologic coverages found elsewhere in Professional Paper 1625-C. The attributes were generated from public data found in the geochemical dataset found in Chap. E, Appendix 2, Disc 1, as well as some additional proprietary data. Please see the metadata file found in Chap. E, Appendix 3, Disc 1, for more detailed information on the geochemical attributes....

This sample collection consists of a 1997 donation from the Shell Oil Company to the Alaska Geological Materials Center. It contains approximately 68,000 samples of following types: dart (short seafloor cores), seismic shothole, outcrop, and megafossils. 80% of the collection are outcrop samples. 5 percent of the collection has been inventoried with specific locations. Most of the collection is in good shape though many megafossil sample bags need to be replaced. The remainder of the collection will be inventoried in a future data preservation project

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.
