These are shape files of final unioned polygon coverages used to calculate coal resources of the B and D coal zones, Lower White River coal field, Deserado assessment area, northwestern Colorado. Desbfing was used for the B coal zone; Desdfing was used for the D coal zone. Polygons that make up the final unioned polygons include counties, 7.5' quadrangles, townships, surface and coal ownership, lease area, overburden, and coal thickness categories. The final coverages were clipped to the resource areas for each coal zone, which are described in the metadata files for the des_bnd coverages.

This is a shapefile and the final unioned polygon coverage used to calculate coal resources of the Fruitland Formation, San Juan Basin coal assessment area, Colorado and New Mexico. Polygons that make up the final unioned polygons include counties, 7.5' quadrangles, townships, surface and coal ownership, reliability, overburden categories, and net coal thickness categories. The final unioned coverage was clipped by the resource boundary polygon, which is described in the metadata file for the shapefile SJB_BND.

Land status and Federal mineral ownership in the Danforth Hills coal field, northwestern Colorado. Polygons that make up the ownership coverage include counties, 7.5' quadrangles, townships, surface and coal ownership. The ownership coverage was clipped to the base of the A and B coal zones or top of the Trout Creek Sandstone Mbr.

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 is a point file that contains data for coal and other stratigraphic horizons in in the Calico and A-sequences of the Straight Cliffs Formation (Upper Cretaceous) east of 112 degrees of longitude in the Kaiparowits Plateau. The item map# is the number of the data point on the index map (Figure A, Plate 1). The map# that refers to a record in the data table (Appendix 1) in Hettinger and others, chap. T. Buffers were drawn at a three-mile distance from data points in this coverage to create the reliability coverage.

This is a shape file and coverage of the top of the Rollins Sandstone Member. It outlines the area underlain by the coal-bearing Cameo/Fairfield coal group in the southern Piceance Basin coal assessment area. Also, it delimits the area within which resources were calculated and reported in the southern Piceance Basin coal assessment area. The polygon was adjusted to match the topography of the DEM.

An ESRI GRID raster data model and TIN model of the overburden material above the LaClede bed of the Laney Member of the Eocene Green River Formation was needed to perform calculations in the Green River and Washakie Basins, southwestern Wyoming as part of a National Oil Shale Assessment.

This is a polygon coverage that represents areas underlain by the coal-bearing Calico and A-sequences of the Straight Cliffs Formation east of 112 degrees of longitude. It differentiates between areas that contain the entire coal-bearing interval and areas where the coal-bearing strata are partially eroded. The outermost polygon defines the base of the Calico and A-sequences. The inner polygon shows where the complete coal-bearing interval is preserved. The area between the outer and inner polygon shows where the coal-bearing rocks are partially eroded. The northern boundary is delineated by the Paunsaugunt fault and volcanic rocks of Tertiary age.
