Texas
Subcontractors for the Savannah River Laboratory (SRL) collected at least 279 stream-sediment samples within 4 counties along the eastern border of Texas as part of the NURE Hydrogeochemical and Stream Sediment Reconnaissance (HSSR) program. The sampling effort was completed between August and October of 1978 and included portions of the Palestine, Alexandria, Beaumont, and Lake Charles 1:250,000-scale quadrangles. (None of the stream-sediment samples were collected within the Tyler quadrangle.) These samples were sent to SRL for analysis of uranium and 16 additional elements. SRL was only able to analyze 26 of the 279 stream-sediment samples collected in Texas. The analytical and site location data for all Texas sediment samples were released as a separate file in the Arkansas, Louisiana, Mississippi, Missouri, Oklahoma, and Texas Data Report [GJBX-104(82)].
Louisiana
Subcontractors for the Savannah River Laboratory (SRL) collected at least 1,017 stream sediment samples within 15 parishes of central Louisiana as part of the NURE Hydrogeochemical and Stream Sediment Reconnaissance (HSSR) program. The sampling effort was completed between August and October of 1978 and included portions of the Alexandria, Baton Rouge, Jackson, Lake Charles, Natchez, Palestine, Shreveport, and Tyler 1:250,000-scale quadrangles. (A total of 5 samples were collected within the Tyler quadrangle.) These sediment samples were sent to SRL for analysis of uranium and 16 additional elements. SRL was able to analyze only 28 Louisiana stream sediment samples; none of these samples were from the Tyler quadrangle. The analytical and site location data for all Louisiana sediment samples were released as a separate file in the Arkansas, Louisiana, Mississippi, Missouri, Oklahoma, and Texas Data Report [GJBX-104(82)].
SRL: Tyler Quadrangle
SRL did not release a separate report for the Tyler quadrangle.
ORGDP: Jackson, Shreveport, and Tyler Quadrangles
SRL sent several Louisiana sediment samples to the Oak Ridge Gaseous Diffusion Plant (ORGDP) for analysis of uranium and 31 additional elements. ORGDP released the analytical data for 209 samples in the Jackson, Shreveport, and Tyler Quadrangles GJBX-68(82) Data Report. This report includes data for 5 sediment samples from the Tyler quadrangle. The site coding information for this data set was summarized in the GJBX-57(82) report.
Summary Tables
Because of the various laboratories and analytical methods used, some SRL samples may have been analyzed once, twice, or not at all. The following table summarizes the analysis of Tyler quadrangle samples.
Laboratory Analysis | Sediments | Waters |
---|---|---|
Only SRL | 0 | 0 |
Only ORGDP | 5 | 0 |
Both SRL and ORGDP | 0 | 0 |
None | 0 | 0 |
Total Samples | 5 | 0 |
Total Data Records | 5 | 0 |
The following is a list of all sample types collected and reported for NURE studies in the Tyler quadrangle.
Sediment Sample Type | Number of Samples | Water Sample Type | Number of Samples |
---|---|---|---|
Wet Streams | 5 | ||
Total Sediments | 5 | Total Waters | 0 |
These Tyler quadrangle samples were analyzed by one or more of the following methods:
Sediment Samples
Water Samples
Sediment Records
The Tyler quadrangle sediment data consist of records from the Louisiana portion of the Arkansas, Louisiana, Mississippi, Missouri, Oklahoma, and Texas GJBX-104(82) Data Report combined with records from the ORGDP Jackson, Shreveport, and Tyler Quadrangles GJBX-68(82) Data Report. When combining sample records, site descriptive information and coordinates were compared for all corresponding records. The following problems were found and addressed during the comparison and reformatting stages for the Tyler quadrangle sediment 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).
Tyler Quadrangle Sediment Data - 5 records
In the eastern United States, SRL collected samples primarily by county or parish. Often, not all counties or parishes within a quadrangle were completely sampled. Sample coverage in the Tyler quadrangle is limited only to the De Soto Parish. This parish is found only along the southeast border of the Tyler quadrangle. The laboratory and analytical methods used also may vary by county or parish such that adjacent counties or parishes often have very different analytical coverages.
None found.
