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.

These are shapefiles and ARC/INFO coverages that outline the areas within which coal resources are calculated and reported for the A/B through G coal zones, Danforth Hills coal field. The shapefile DANABBNDG is the defining resource polygon for the A and B coal zones; DANCbndg is the defining resource polygon for the C coal zone, and so on.

These data represent major fault zones as indicated on Plate 2, Principal structural features, Gulf of Mexico Basin (compiled by T.E. Ewing and R.F. Lopez) in volume J, The Geology of North America (1991). This dataset contains basic data and interpretations developed and compiled by the U.S. Geological Survey's Framework Studies and Assessment of the Gulf Coast Project. Other major sources of data include publicly available information from state agencies as well as publications of the U.S. Geological Survey and other scientific organizations. In cases where company proprietary data were used to produce various derivatives such as contour surfaces, the source is cited but the data are not displayed.

This is a coverage that shows areas in the Kaiparowits Plateau where geologic conditions in the Calico and A-sequences are more favorable for current underground mining technology (Hettinger and other, chap. T). This coverage contains numerous attributes of information. It was compiled by computing the geometric intersection of nine polygon coverages using the ARC/INFO UNION command. This coverage is characterized as being a GUIDE TO WHERE THE MORE FAVORABLE COAL AREAS ARE LIKELY TO BE for current underground mining technology: areas where coal beds in the Calico and A-sequences are greater than 3.5 feet thick, less than 3,000 feet deep, and inclined by less than 12 degrees, as described in Hettinger and others,...

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.
