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.

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.

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 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 U.S. Geological Survey (USGS) has compiled a geodatabase containing mineral-related geospatial data for the People's Republic of China. 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 by updating and publishing the georeferenced locations of mineral commodity production and processing facilities, mineral...

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.

Compilation of Geospatial Data (GIS) for the Mineral Industries and Related Infrastructure of Africa
This geodatabase reflects the U.S. Geological Survey’s (USGS) ongoing commitment to its mission of understanding the nature and distribution of global mineral commodity supply chains by updating and publishing the georeferenced locations of mineral commodity production and processing facilities, mineral exploration and development sites, and mineral commodity exporting ports in Africa. The geodatabase and geospatial data layers serve to create a new geographic information product in the form of a geospatial portable document format (PDF) map. The geodatabase contains data layers from USGS, foreign governmental, and open-source sources as follows: (1) mineral production and processing facilities, (2) mineral exploration...
Subsurface microbial (biogenic) methane production is an important part of the global carbon cycle and has resulted in natural gas accumulations in many coal beds worldwide. Laboratory experiments indicate coal beds can act as natural geobioreactors and produce additional low carbon renewable natural gas with algal or yeast compounds, yet the effectiveness of these nutrients in situ are unknown. This study uses down-well monitoring methods in combination with deuterated water (99.99% D2O) and a 200-liter injection of 0.1% yeast extract to stimulate and isotopically label newly generated methane. A total dissolved gas pressure sensor was placed down-well into the Flowers-Goodale coal bed at the USGS Birney Test Site...
The Middle Pennsylvanian (Bolsovian) Leatherwood coal in central eastern Kentucky is a moderately thick (up to >1.6 m in the sites examined in this study) coal bed that has been one of the major sources of electricity in the region. To document and understand the organic petrology and inorganic chemistry of the Leatherwood coal, geologists from the University of Kentucky Center for Applied Energy Research (CAER), Kentucky Geological Survey (KGS), and U.S. Geological Survey (USGS) collected 45 bench samples of the Leatherwood coal in the late-1980’s through the early-2000’s. USGS laboratories analyzed the chlorine and selenium contents of 27 bench samples by ion chromatography (IC) and hydride generation-atomic absorption...
