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 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 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 dataset is a point coverage of attributes on data location, thickness of the Fire Clay coal zone, and its elevation, in feet. 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 file is also found as an ASCII Appendix of Chapter F, Disc 1 found elsewhere in Professional Paper 1625-C.

Pittsburgh Coal Bed Remaining Resources by County in Pennsylvania, Ohio, West Virginia, and Maryland
This dataset is a polygon coverage of counties limited to the extent of the Pittsburgh coal bed resource areas and attributed with remaining resource values 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.

Coal and coal byproducts may be economically important resources if enriched in critical minerals such as rare earth elements. The organic carbon they contain could be converted to gas using stimulated microbial methanogenesis. In this study, samples were collected from two underground mine sites in the bituminous region of southwest Pennsylvania to assess the potential for these uses from different types of stockpiled coal, including raw coal, clean coal, and refuse coal. Samples were analyzed for coal quality using proximate, ultimate, and sulfur forms analyses, and for major and trace elements. These data complement previous USGS studies on coal waste conducted in Pennsylvania and the Illinois Basin.

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 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...

The U.S. Geological Survey (USGS) has compiled a geodatabase containing mineral-related geospatial data for 10 countries of interest in Southwest Asia (area of study): Afghanistan, Cambodia, Laos, India, Indonesia, Iran, Nepal, North Korea, Pakistan, and Thailand. The data can be used in analyses of the extractive fuel and nonfuel mineral industries and related economic and physical infrastructure integral for the successful operation of the mineral industries within the area of study as well as the movement of mineral products across domestic and global markets. This geodatabase reflects the USGS ongoing commitment to its mission of understanding the nature and distribution of global mineral commodity supply chains...
