This dataset is a polygon coverage of the thickness of the overburden of the Pocahontas No. 3 coal bed, in feet. It was produced by importing 1:100,000 (30-minute) and 1:24,000 scale (7.5-minute) digital elevation models (DEM) into ARC, and merging the lattices into one. The structure elevation grid for the Pocahontas No. 3 coal bed was subtracted from the surface elevation grid, creating overburden thickness. This grid was contoured within the known extent of the Pocahontas No. 3 coal bed into 200, 500, 1000, 2000, and 3000 foot lines. This vector file was imported to ARC. Polygon attributes include a code for the USGS overburden category (Coal Resource Classification of the U.S. Geological Survey, USGS, Circular...

This is a point coverage that contains data for coal and otherstratigraphic horizons in the John Henry Member of the StraightCliffs Formation (Upper Cretaceous) east of 112 degrees oflongitude in the Kaiparowits Plateau. The item map# is the numberon the index map (Figure A, Plate 1) that refers to a record in adata table (Appendix 1) in Hettinger and others (1996). Bufferswere drawn at a three-mile distance from data points in thiscoverage to create the reliability coverage. This coverage alsoincludes arcs representing lines of cross section shown in Figs. B,C, D and E, Plate 1 (Hettinger and others, 1996).
This dataset is a collection of major coal mine productionlocated in The Peoples Republic of China. Included in thisdataset are the locations of major coal mines and theapproximate annual amount of coal mined annually in millionsof metric tons.
The Raton basin is a large asymmetric syncline (2500 mi2 area) that extends from Huerfano Park, Colorado to Cimarron, New Mexico. As used here, the basin is defined by the limits of the outcrop of the Trinidad Sandstone. The Cretaceous and Tertiary rocks are sharply flexed to form hogbacks along the western margin of the basin on the east flank of the Sangre de Cristo Mountains. These rocks assume more gentle dips along the other margins of the Raton basin and are highly dissected. The Late Cretaceous in the Raton basin was a period of emergence of land and retreat of the Cretaceous epeiric sea. The coastline advanced eastward across New Mexico, as broad prograding deltaic and barrier coastal plains were formed...
This is a line coverage of mine adits within the Kaiparowits Plateau study area; they are shown in figure 1 of Hettinger and others, 1996.
This location is part of the Arizona Mineral Industry Location System (AzMILS), an inventory of mineral occurences, prospects and mine locations in Arizona. Navajo169 is located in T36N R18E Sec 9 SW in the Long House Valley - 7.5 Min quad. This collection consists of various reports, maps, records and related materials acquired by the Arizona Department of Mines and Mineral Resources regarding mining properties in Arizona. Information was obtained by various means, including the property owners, exploration companies, consultants, verbal interviews, field visits, newspapers and publications.

To test if reflectance increases to sedimentary organic matter (vitrinite) caused by broad ion beam (BIB) milling were related to molecular aromatization and condensation, we used Raman and Fourier transform infrared (FTIR) spectroscopies to evaluate potential compositional changes in the same vitrinite locations pre- and post-BIB milling. The same locations also were examined by atomic force microscopy (AFM) to determine topographic changes caused by BIB milling (as expressed by the areal root-mean-square roughness parameter Rq). Samples consisted of four medium volatile bituminous coals. We used a non-aggressive BIB milling approach with conditions of [(5 min, 4 keV, 15°incline, 360° rotation at 25 rpm and 100%...

This data contains the location of coal resources within the State of Alaska. It is based on the 1986 Map of Alaska's Coal Resources, Alaska Division of Mining and Geological & Geophysical Surveys, Special Report 37, in cooperation with the Alaska Coal Association.
This is a polygon coverage of the inclination of strata within theKaiparowits Plateau. Inclinations of strata are attributed incategories that range from 0 - 6, 6 - 12, 12 - 25, and > 25degrees. The range-of-dip was compiled at 1:125,000-scale fromstructure contour lines and from dip measurements on 1:24,000-scalepublished geologic maps of the Kaiparowits Plateau. These geologicmaps are referenced in figure 2 of Hettinger and others (1996).The outside polygon defines the base of the coal-bearing John HenryMember of the Straight Cliffs Formation (Upper Cretaceous) east of112 degrees of longitude. The northern boundary is delineated bythe Paunsaugunt fault and volcanic rocks of Tertiary age. The areawithin this polygon...
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 is a polygon coverage of the outcrop of the base of the DripTank Member of the Straight Cliffs Fm. (Upper Cretaceous) east of112 degrees of longitude. The northern boundary is delineated bythe Paunsaugunt fault and volcanic rocks of Tertiary age.
The data release encapsulates geospatial data in support of the regional scale study, Coal Geology and Assessment of Coal Resources and Reserves in the Little Snake River coal field and Red Desert assessment area, Greater Green River Basin, Wyoming. The assessment area covers about 2,300 square miles of the Eastern portion of the 15,400 square mile Greater Green River Basin in Southwestern Wyoming. This release includes geospatial data for the study area boundary, depth to coal, thickness of coal, outcrops and reliability. These data were compiled from numerous sources, the primary one being a database of point data that resides in a separate data release.

This is a polygon coverage of the outcrop of the base of theWahweap Formation (Upper Cretaceous) east of 112 degrees oflongitude. This polygon also represents undivided Tertiary andCretaceous: Osiris Tuff and Wasatch Fm (Tertiary), Pine HollowFm (Tertiary?), Canaan Peak Fm (Tertiary? and Cretaceous), andKaiparowits and Wahweap Formations (Cretaceous). The northernboundary is delineated by the Paunsaugunt fault and volcanic rocksof Tertiary age.
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. The Middle...

This is a polygon coverage that represents the extent of thestudy area and is attributed to indicate where the totalcoal-bearing interval is represented and where the entiresection may not be represented in parts of the coal-bearinginterval due to erosion. The extent of the study area is theoutcrop of the Calico Sequence boundary and defines the baseof the coal-bearing John Henry Member of the Straight CliffsFormation east of 112 degrees of longitude. The northernboundary is delineated by the Paunsaugunt fault and volcanicrocks of Tertiary age.
