South Carolina
Subcontractors for the Savannah River Laboratory (SRL) collected at least 3,618 stream-sediment and 3,945 ground-water samples within 46 counties from South Carolina as part of the NURE Hydrogeochemical and Stream Sediment Reconnaissance (HSSR) program. The sediment samples were collected during June - October 1976; April 1977; and January - April 1978, and water samples were collected during December 1976 - July 1977 and January - September 1978. Sample coverage included portions of the Athens, Augusta, Charlotte, Florence, Georgetown, Greenville, James Island, Knoxville, Savannah, and Spartanburg 1:250,000-scale quadrangles. (A total of 656 stream-sediment and 362 ground-water samples were collected within the Greenville quadrangle.) These samples were sent to SRL for analysis of uranium and additional elements (16 in sediments and 9 in waters). SRL was able to analyze 3,581 sediments and 3,941 waters from South Carolina; this includes 652 sediment and 361 water samples from the Greenville quadrangle. The analytical and site location data for all South Carolina samples were released in the North and South Carolina Data Report [GJBX-102(82)].
SRL sent 2,483 sediment samples from South Carolina to an unnamed contract laboratory for "Supplemental Analyses." Supplemental analytical determinations for up to 23 elements were reported for 2,476 of these samples in the North and South Carolina Data Report [GJBX-102(82)]. The digital data file accompanying this report includes Supplemental Analyses for 639 South Carolina sediment samples within the Greenville quadrangle.

SRL was able to analyze 5,958 sediments and 5,989 waters from Georgia; this includes 772 sediment and 398 water samples from the Greenville quadrangle. The analytical and site location data for all Georgia samples were released in the Alabama and Georgia Data Report [GJBX-403(81)].
SRL sent 2,956 sediment samples from Georgia to an unnamed contract laboratory for "Supplemental Analyses." Supplemental analytical determinations for up to 23 elements were reported for 2,951 of these samples in the Alabama and Georgia Data Report [GJBX-403(81)]. The digital data file accompanying this report includes Supplemental Analysis records for 765 Georgia sediment samples within the Greenville quadrangle.
North Carolina
Subcontractors for the Savannah River Laboratory (SRL) collected at least 6,666 stream-sediment, 295 surface-water, and 5,778 ground-water samples within 100 counties from North Carolina as part of the NURE Hydrogeochemical and Stream Sediment Reconnaissance (HSSR) program. The sediment samples were collected during June - December 1976; July - August 1977; and April - May 1978, and water samples were collected during December 1976 - August 1977 and June - July 1978. Sample coverage included portions of the Beaufort, Charlotte, Chattanooga, Currituck Sound, Florence, Georgetown, Greensboro, Greenville, Johnson City, Knoxville, Manteo, Norfolk, Raleigh, Rocky Mount, Rome, Spartanburg, and Winston-Salem 1:250,000-scale quadrangles.

These samples were sent to SRL for analysis of uranium and additional elements (16 in sediments and 9 in waters). SRL was able to analyze 5 sediment and 1 water samples from the Greenville quadrangle. The analytical and site location data for all North Carolina samples were released in the North and South Carolina Data Report [GJBX-102(82)].
SRL sent 4,677 sediment samples from North Carolina to an unnamed contract laboratory for "Supplemental Analyses." Supplemental analytical determinations for up to 23 elements were reported for 4,660 of these samples in the North and South Carolina Data Report [GJBX-102(82)]. The digital data file accompanying this report includes Supplemental Analyses for 5 North Carolina sediment samples within the Greenville quadrangle.
SRL: Greenville Quadrangle
SRL released a separate quadrangle report for the Greenville NTMS quadrangle, which includes data for 1,413 stream-sediment and 731 ground-water samples. With only a few exceptions, these stream-sediment sample data are not the same as the that for corresponding sample records found in the Georgia and North and South Carolina State reports. With only minor differences, these ground-water data are the same as that for corresponding Georgia and North and South Carolina State reports. SRL released the analytical data as the Greenville Quadrangle GJBX-47(78) Preliminary Basic Data Report. The site coding information for this data set is summarized within the text of this report.
SRL: Athens, Charlotte, Greenville, and Spartanburg Quadrangles
SRL released a separate report for supplemental analyses of 5,068 sediment samples from the Athens, Charlotte, Greenville, and Spartanburg quadrangles. Supplemental analytical determinations for up to 19 elements were reported for 5,032 of these samples in the Athens, Charlotte, Greenville, and Spartanburg NTMS Quadrangle Areas, Supplemental Data Release [GJBX-73(79)]. The digital data file accompanying this report includes supplemental analyses for 1,409 sediment samples collected within the Greenville quadrangle.
Gold Analyses
Data for gold analyses of sediments by SRL neutron activation were released in the GJBX-135(82) summary report. The introduction of that report states:
"This report contains previously unreported neutron-activation analyses of gold in sediment samples determined at SRL. These data were not included in the standard SRL NURE data reports because the gold spectrum was not measured in the original analytical procedure and the report format was designed without the gold analyses being included. Gold analyses became available as the analytical procedure was refined, but the report format was not modified to incorporate these data."
Only those sediment samples that had detectable concentrations of gold by neutron activation analysis were given in the GJBX-135(82) report. Sediment samples with concentrations below detection limits were not reported and can only be ascertained by identifying which samples were actually analyzed by neutron activation at SRL.

Sediment Records
The Greenville quadrangle sediment data consist of reformatted records from the Greenville Quadrangle GJBX-47(78) Data Report. These records were compared with corresponding sample records from the North and South Carolina portions of the North and South Carolina [GJBX-102(82)] Data Report along with sample records from the Georgia portion of the Alabama and Georgia [GJBX-403(81)] Data Report. The following problems were found and addressed during the comparison and reformatting stages for the Greenville quadrangle sediment data:
Water Records
The Greenville quadrangle water data consist of reformatted records from the Greenville Quadrangle GJBX-47(78) Data Report. These records were compared with corresponding sample records from the the North and South Carolina portions of the North and South Carolina [GJBX-102(82)] Data Report along with sample records from the Georgia portion of the Alabama and Georgia [GJBX-403(81)] Data Report. The following problems were found and addressed during the comparison and reformatting stages for the Greenville quadrangle water data:
The NURE HSSR data are now available online in two databases: The sediment database (also includes data for soils and some rocks) at http://tin.er.usgs.gov/nure/sediment/ and the water database at http://tin.er.usgs.gov/nure/water/. From these two web sites, NURE HSSR data can be selected, examined, summarized, and downloaded by political boundaries (State and County), by quadrangle (1:250,000-scale, 1:100,000-scale, and 1:63,360-scale for Alaska or 1:24,000-scale for the Lower 48 States), and by hydrologic unit (drainage region, subregion, river basin, or sub-basin). Selected data can be downloaded as a dBase file, a shapefile, an HTML table, or ASCII text (tab- or comma-delimited).
Greenville Quadrangle Sediment Data - 2,834 records
Greenville Quadrangle Water Data - 763 records
In the eastern United States, SRL collected samples primarily by county. Often, not all counties within a quadrangle were completely sampled. Sample coverage in the Greenville quadrangle is complete and includes samples from Banks, Barrow, Clarke, Dawson, Elbert, Forsyth, Franklin, Gwinnett, Habersham, Hall, Hart, Jackson, Lumpkin, Madison, Oglethorpe, Rabun, Stephens, Towns, Union, and White Counties in Georgia; Abbeville, Anderson, Greenville, Greenwood, Laurens, McCormick, Oconee, Pickens, and Spartanburg Counties in South Carolina; and Clay and Macon Counties in North Carolina. The laboratory and analytical methods used also may vary by county such that adjacent counties often have very different analytical coverage.
Six stream-sediment samples and two ground-water samples within the Greenville quadrangle were not analyzed by any of the various laboratories. The following table summarizes the locations of those unanalyzed samples.
State | County | Sample Media | Unanalyzed Samples | Total Samples |
---|---|---|---|---|
Georgia | Hall | Sediment | 1 | 84 |
Georgia | Rabun | Sediment | 1 | 73 |
Georgia | White | Water | 1 | 22 |
South Carolina | Greenwood | Sediment | 2 | 62 |
South Carolina | Laurens | Sediment | 2 | 65 |
South Carolina | Pickens | Water | 1 | 41 |
Crystalline Rock Areas of Southeastern United States
A study of the Crystalline Rock Areas of Southeastern United States [GJBX-9(76)] was undertaken as part of a series of orientation studies conducted by SRL in the Eastern States. In 1975, SRL collected stream-sediment, suspended sediment, ground-water, and stream-water samples from Lamar County Area in Georgia (Athens, Atlanta, Macon and Phenix City quadrangles), Oconee County Area in South Carolina (Greenville and Knoxville quadrangles), and the Brush Creek and North Harper Areas in North Carolina (Charlotte, Johnson City, Knoxville, and Winston-Salem quadrangles). These four areas were selected for orientation studies to aid in the design of the geochemical reconnaissance program for uranium being conducted in the eastern United Sates by SRL. Water samples were analyzed by Neutron Activation for uranium. Sediment samples were analyzed for uranium by Neutron Activation and for Ag, Ba, Be, Co, Cr, Cu, La, Nb, Ni, Pb, V, and Zn by semi-quantitative emission spectroscopy. Data tables of analytical results are included within the report. No digital data files were available for reformatting.
Geochemical Anomaly Evaluation Studies
The University of Georgia, under subcontract to Bendix Field Engineering Corp., evaluated uranium anomalies in the Charlotte, Greenville, Spartanburg, and Winston-Salem quadrangles of the southeastern United States and in the Tallahassee Creek area of the Pueblo quadrangle in Colorado. During this study, 170 stream-sediment samples were collected at 26 sites. Up to four different subsets of these samples were analyzed: Fe, Mn, and U in oxalic acid residues derived from boulder coatings; U and Fe in oxalic acid residues derived from -80 mesh stream sediment; total U, Th, and Fe in -80 mesh stream sediments with heavy minerals removed; and total U and Th in -80 mesh stream sediments. The analytical data for these samples were released as appendices in the GJBX-114(80) report.
As part of the development program to support interpretation of HSSR geochemical data, SRL conducted a series of anomaly verification field studies identified in HSSR data. SRL conducted a anomaly verification study in the Greenville and Greer 15' quadrangles located in the northeast corner of the Greenville 1:250,000-scale quadrangle [GJBX-205(82)]. A total of 2,826 field scintillometer readings were taken in the Greenville 15' quadrangle and 2,240 field scintillometer reading were taken in the Greer 15' quadrangle. Data tables of these reading are included within the microfiche accompanying the report. No digital data files were available for reformatting.
SRL conducted a anomaly verification study in the Avalon, Greer, Honea, and Northeast Greenville quadrangles located in the northeast corner of the Greenville 1:250,000-scale quadrangle [GJBX-211(82)]. This report includes a generalized geologic and petrographic interpretation of each of these quadrangles. In addition, this report includes multielement analyses for 50 ground-water and 28 stream-sediment samples collected within the Avalon quadrangle. The stream-sediment samples were sieved into four different size fractions before analysis. Data table of these analyses are included in tables within the report. No digital data files were available for reformatting.
Mineral Chemistry of the Southeastern Piedmont
SRL conducted an analysis of monazite, zircon, and apatite in the Southeastern Piedmont [GJBX-101(82)]. SRL collected 263 monazite, 191 zircon, and 16 apatite grains from 52 stream-sediment locations and analyzed them by electron microprobe for one of the two following suites of elements: Ca, La, Ce, Pr, Nd, Sm, Eu, Gd, Er, Dy, Y, Th, U, and F, or Ca, La, Ce, Fe, Er, Hf, Y, Th, U, P, Zr, Mg, Al, and Si. Samples were collected along eight traverses where reconnaissance data had previously revealed high concentrations of uranium, thorium, and cerium in Georgia, North Carolina, and South Carolina (Athens, Augusta, Charlotte, Greenville, Knoxville, and Spartanburg 1:250,000-scale quadrangles). Data tables of analytical results are included within the report. No digital data files were available for reformatting.
Characteristics of the Southeastern Piedmont
Bendix Field Engineering Corporation released a report that contains stream-sediment, hydrogeochemical, and aeromagnetic data for 16 contiguous NTMS quadrangles in the eastern United States [GJBX-40(83)]. This compilation report is limited in scope to features that have specific interest to the geoscience community. Included in the report are aeromagnetic and geochemical maps, and tectonic and igneous rock distribution maps. When used together, these maps show geochemical, tectonic, and magnetic features unique to many of the geologic and physiographic provinces in the region. This report primarily covers the Southeastern Piedmont region and includes the Athens, Augusta, Bluefield, Charlotte, Florence, Georgetown, Greensboro, Greenville, Knoxville, Norfolk, Raleigh, Richmond, Roanoke, Rocky Mount, Spartanburg and Winston-Salem 1:250,000-scale quadrangles. The color maps are in 35mm-slide format. No digital data files accompany this report.
