Research and surveillance reports have documented a significant increase in coal workers' pneumoconiosis, including the most severe forms of progressive massive fibrosis and rapidly progressive pneumoconiosis in U.S. coal miners, particularly those in Appalachian coalfields. Several possible explanations for these observations include excessive exposures to total respirable dust, increased exposure to freshly fractured silica and silicates, or greater exposure to smaller particles that may be the result of changing mining practices. This dataset contains the chemical and morphological characteristics of particulate matter retrieved from lung tissue slices of historical and contemporary miners.

Dataset includes rock and soil gas carbon and strontium values. Rock samples were collected from outcrop locations as well as from drill cuttings. Rock type associations were made based on the DeWitt and others (2008) geology map. Soil gas samples were collected from 4 inch augered soil core holes completed to different depths at three separate sampling locations. Material at the bottom of the soil core hole was collected and analyzed in addition to soil gas for some samples. The augered soil cores were backfilled with two trowel scoops of material removed from soil core then two scoops of clean silica sand were added to the soil core hole. A stainless steel tube was then added to the hole and 10 more scoops...

The Air Force Research Laboratory (AFRL) is about 7 kilometers southwest of Boron, California, and covers 320 square kilometers of Edwards Air Force Base. The AFRL consists of 12 facilities for testing full-size rocket engines, engine components, and liquid and solid propellants. The historical release of contaminants from rocket test stands, evaporation ponds, burn pits, catch basins, and leaking waste-collection tanks has contaminated groundwater in the AFRL. Groundwater aquifers near the AFRL are mostly restricted to fractured granitic bedrock, but previous studies indicate that groundwater and associated contaminants have moved into alluvium to the north and northwest. The U.S. Geological Survey (USGS) and the...

Annual summaries of mineral extraction and exploration activities in Idaho and factors impacting these activities. Published and unpublished content. In 1975 Idaho Geological Survey, then named Idaho Bureau of Mines and Geology, began compiling annual summaries for use by U.S. Bureau of Mines and U.S. Geological Survey annual reports after dissolution of the office of the Idaho State Inspector of Mines in 1974. These state data resources are generally more rich in content and context than federal summaries. As part of an ongoing project funded in part by U.S. Geological Survey and Idaho Department of Lands, data from these documents are being geo-related within the Idaho Geological Survey's Database of Mines and...

Proppants used during hydraulic fracturing of oil and gas wells are manufactured to maximize petroleum yield by controlling the size, shape, density, and strength of the proppant material. The most common types of proppants are mined silica sand and manufactured ceramics, some of which are further modified with organic resin coatings to improve performance. Much of the work on the environmental and human health effects of proppant releases into the environment has focused on occupational silicosis, with little attention given to the potential effects from the organic coatings on these materials. This oversight is especially relevant in the context of dumping of unwanted proppant on the land surface, which has been...

Iron oxide-apatite (IOA) deposits of the Adirondack Mountains of New York locally contain elevated REE concentrations (e.g. Taylor and others, 2019). Critical to evaluating resource potential is understanding the genesis of the IOA deposits that host the REE-rich minerals. As part of this effort, the U.S. Geological Survey (USGS) is conducting bedrock geologic mapping, geochronology, geochemistry, and geophysics in the region. Published and ongoing research demonstrates the spatial association of IOA deposits with the Lyon Mountain Granite Gneiss (LMG), so understanding the relationship of the LMG to the IOA deposits is important for resource evaluation—however the age and origin of the LMG remain contentious. As...

There are over 10,000 hydrothermal features in Yellowstone National Park (YNP), where waters have pH values ranging from about 1 to 10 and surface temperatures up to 95 °C. Active geothermal areas in YNP provide insight into a variety of processes occurring at depth, such as water-rock and oxidation-reduction (redox) reactions, the formation of alteration minerals, and microbial (thermophile) metabolism in extreme environments. Investigations into the water chemistry of YNP hot springs, geysers, fumaroles, mud pots, streams, and rivers have been conducted by the U.S. Geological Survey (USGS) and other earth-science organizations and academic institutions since 1888 (Gooch and Whitfield, 1888). More recently, USGS...

Atmospheric deposition of reactive nitrogen (Nr) can impact the soil microbial community structure and function and thus ecosystem processing and export of nutrients. Ecosystem response to atmospheric inputs of nitrogen depends on several factors, including elevational climate conditions (freeze/thaw cycles, precipitation), geology, soil and vegetation type, N speciation and microbial community structure. The focus of this study was to evaluate how spatial and seasonal variations in N deposition affect the ability of soil microbial communities to process N along an elevational gradient (1700 to 3015 meters) from plains to subalpine ecosystems west of Boulder, Colorado. In conjunction with a study measuring the variability...

Mineral compositions are reported for Quaternary volcanic rocks of the Matan volcanic center, northern Harrat Rahat, Saudi Arabia. Compositions were measured by wavelength-dispersive methods with the 5-spectrometer JEOL-8900 electron microprobe at the USGS facility in Menlo Park, California; background-corrected X-ray intensities were reduced to oxide weight concentrations with the JEOL proprietary version of the CITZAF reduction schema. These results are part of a collaborative study by the U.S. Geological Survey and Saudi Geological survey to assess the volcanic and seismic hazards associated with the northern Harrat Rahat volcanic field.
