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...

This digital geospatial compilation gathered paleoflow indicators from current-formed sedimentary structures throughout the Paleozoic Ozark uplift, Arkoma foreland basin, and Ouachita fold-thrust-belt of eastern Oklahoma and western Arkansas from existing publications. This dataset consists of unidirectional and bidirectional paleocurrents observed from a variety of bedform types represented by approximately 9,958 individual measurements and 665 calculated means (one .csv file) plotted as points (one .shp file) with subordinate Ordovician-Silurian and primarily Mississippian-Pennsylvanian ages.

This data release includes whole rock (WR) geochemical data for 94 samples. Whole rock geochemistry data were analyzed at Actlabs in Ancaster, Ontario, Canada. Rock samples were collected by Peter Valley, Greg Walsh, Arthur Merschat, and Ryan McAleer. The whole rock geochemistry data characterize the composition of mapped meta-igneous rocks in eastern Vermont and western New Hampshire, USA. The data release contains three files, including one metadata file and 2 comma-delimited (CSV) files. The CSV files include the following: BronsonHill_WR_data.csv and BronsonHill_WR_data_dictionary.csv.

This set includes 52 cores collected from the Mohawk River Valley, NY (Herkimer, Fulton, Montgomery, Schoharie, and Saratoga Counties). Each well was cored continuously from the top of bedrock to the total depth (TD), capturing a complete stratigraphic section of Late Ordovician to (in most cases) Precambrian basement. Core diameters are BX and NX, and lengths range from ~400 to ~1400 feet. The Mohawk Valley cores are of particular value because they were collected at the north end of the Appalachian Basin, in an area where there has been little other exploratory drilling. The results from previous analyses are available upon request.

The geologic map database of the Great Smoky Mountains National Park region of Tennessee and North Carolina is a result from studies from 1993 to 2003 as part of a cooperative investigation by the U.S. Geological Survey with the National Park Service (NPS). This work resulted in a 1:100,000-scale geologic map derived from mapping that was conducted at scales of 1:24,000 and 1:62,500. The geologic data are intended to support cooperative investigations with the NPS, the development of a new soil map by the Natural Resources Conservation Service, and the All Taxa Biodiversity Inventory. In response to a request by the NPS, we mapped previously unstudied areas, revised the geology where problems existed, and developed...
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...

The 1:100,000-scale geologic map database of the South Boston 30' × 60' quadrangle, Virginia and North Carolina, provides geologic information for the Piedmont along the I-85 and U.S. Route 58 corridors and in the Roanoke River watershed, which includes the John H. Kerr Reservoir and Lake Gaston. The Raleigh terrane (located on the eastern side of the map) contains Neoproterozoic to early Paleozoic(?) polydeformed, amphibolite-facies gneisses and schists. The Carolina slate belt of the Carolina terrane (located in the central part of the map) contains Neoproterozoic metavolcanic and metasedimentary rocks at greenschist facies. Although locally complicated, the slate-belt structure mapped across the South Boston...
The Ouachita Mountains record the late Paleozoic Laurentia-Gondwana orogenic event along southern Paleo-North America during Pangea supercontinent formation. This data release contains a digital compilation of geomorphic-structural information from the Ouachita Mountains of southeastern Oklahoma and southwestern Arkansas as previously published by Arbenz (2008). The geodatabase, presented herein, contains feature classes that include contact, fault, fold, and cross section lines with map unit polygons characterized by predominantly siliciclastic material with primarily Paleozoic depositional ages. Spatial data are also disseminated as shapefiles, accompanied by applicable non-spatial tables detailing the data sources,...

This dataset captures in digital form previously published maps showing the inferred extent and subsurface elevation of several Paleozoic consolidated rock units in the northern Midwest of the United States. Data released here were published as figures within a U.S. Geological Survey (USGS) Water Mission Area report documenting results from a study of the regional hydrogeology and ground-water quality of the Cambrian-Ordovician aquifer system in the northern Midwest. This study was part of the USGS national Regional Aquifer-System Analysis (RASA) Program. Sandstone and carbonate rocks of Cambrian and Ordovician age compose much of the sedimentary rocks overlying the Precambrian basement in the northern Midwest and...
