The geology of an area of 660 square miles mostly in the northeastern corner of Tennessee and small adjacent areas in Virginia and North Carolina is the subject of this report. The region lies principally in the Unaka province, with extensions northwestward into the Appalachian Valley and southwestward into the Blue Ridge province. The report combines results of surveys made between 1941 and 1953 by the U. S. Geological Survey, the Tennessee Division of Geology, and the Tennessee Valley Authority, and is published in cooperation with the Tennessee Division of Geology. Northeasternmost Tennessee is a region of widespread mineralization and was formerly important for mineral production. Iron, manganese, and bauxite...

The physical location is 900 Natural Resources Dr., Ste 400, Charlottesville, VA 22903. Room 1093 (photolab) The author is unknown. The image is dated unknown.
This folder contains unpublished and georeferenced hand drawn geologic maps of five 7.5-minute quadrangles: Grayson, Konnarock, Whitetop Mountain, Park, and Troutdale. Geology was mapped by Douglas W. Rankin from 1962-1969 and compiled thereafter. The maps were scanned in 2016. Data from these maps were compiled in ArcGIS and incorporated into an in progress geologic map of the Mount Rogers area, VA-NC-TN. Please contact the Eastern Geology and Paleoclimate Science Center for additional information and access to original copies.
Historic image BR�009 is part of the 'Historic photolab Images' collection; the topic area is 'Blue Ridge'. Location is Virginia (estimated). The image has the following description: 'Blue Ridge Parkway Tourist handout .' The image was scanned from a photo as part of the USGS NGGDPP deliverable for 2016-2017. The physical location is 900 Natural Resources Dr., Ste 400, Charlottesville, VA 22903. Room 1093 (photolab) The author is unknown. The image is dated 19410101.

Dependable access to critical minerals information is vital to ensuring the continued domestic security and economic prosperity of the United States. At present, Alabama has known deposits, prospects, and occurrences of at least 21 of these commodities, including aluminum, arsenic, barium, beryllium, chromium, cobalt, fluorite, graphite, lithium, magnesium, manganese, platinum group metals (PGMs), rare earth elements (REEs), tantalum, tin, thorium, titanium, uranium, vanadium, zinc, and zirconium; but may have as many 31, including potential occurrences of gallium, germanium, hafnium, indium, lanthanum, nickel, niobium, rhenium, selenium, and yttrium. Although none of these commodities are currently being produced...

In 2013, the U.S. Geological Survey (USGS) in partnership with the U.S. Federal Highway Administration (FHWA) published a new national stormwater quality model called the Stochastic Empirical Loading Dilution Model (SELDM; Granato, 2013). The model is optimized for roadway projects but in theory can be applied to a broad range of development types. SELDM is a statistically-based empirical model pre-populated with much of the data required to successfully run the application (Granato, 2013). The model uses Monte Carlo methods (as opposed to deterministic methods) to generate a wide range of precipitation events and stormwater discharges coupled with water-quality constituent concentrations and loads from the upstream...

Regional geologic investigations show that all the metamorphosed crystalline rocks underlying the Greenville 1 degree x 2 degree quadrangle are allochthonous. Seismic-reflection studies, the COCORP line (Cook and others, 1979), and the U.S. Geological Survey (USGS) seismic lines (Harris and Bayer, 1979; Harris and others, 1981) present seismic profiles across different parts of the southern Appalachians. Recent geophysical studies for the now discontinued Appalachian Ultradeep Core Hole (ADCOH) project were concentrated in the Greenville quadrangle (Hatcher and others, 1988). The ADCOH seismic-reflection profiles tie in with the COCORP profile of Cook and others (1979), providing a three-dimensional view of the...
Note: this data release is currently being revised and is temporarily unavailable. A water-supply plan is being developed for Wake County, North Carolina, in accordance with the 50-year planning window used by the North Carolina Division of Water Resources for residents in unincorporated areas of the county. To develop this supply plan, Wake County seeks to better understand the sustainability of groundwater resources of the regolith/fractured-rock aquifer system. Slug tests were performed in 17 wells in the Wake County area, during 2020 and 2021, to provide values of horizontal hydraulic conductivity and transmissivity to support the development of Wake County’s water-supply plan. Wake County is in the Piedmont...
