Brief History and Description of Data

[See History of NURE HSSR Program for a summary of the entire program.]

ORGDP: Rice Lake Quadrangle
A total of 541 stream-sediment, 518 ground-water, and 533 surface-water samples was collected from the Rice Lake quadrangle as part of the Oak Ridge Gaseous Diffusion Plant (ORGDP) Rice Lake Quadrangle NURE Hydrogeochemical and Stream Sediment Reconnaissance (HSSR) study. Samples were collected between August and November of 1977 by Uranium Resource Evaluation Project personnel of the Oak Ridge Gaseous Diffusion Plant, Oak Ridge, Tennessee. These samples were analyzed by the ORGDP for uranium and other elements. The analytical data were released as the Rice Lake Quadrangle NURE HSSR study GJBX-95(78) report.

Summary Tables
Because of the various analytical methods used, some ORGDP samples may have been analyzed once, twice, or not at all. The following table summarizes the analysis of Rice Lake quadrangle samples.

Discussion of the Reformatting Process for Rice Lake Quadrangle

The Rice Lake quadrangle sediment and water data consist of reformatted records from the Rice Lake Quadrangle NURE HSSR study GJBX-95(78) report. The following problems were found and addressed during the comparison and reformatting stages for these data:

Sediment Records

  1. There were 527 sediment samples that were apparently analyzed twice by slightly different multielement methods. To avoid losing data for elements analyzed by both methods, these samples are each represented by two records in the sediment data.
  2. One sediment sample found in the digital data file was not listed in the Rice Lake Quadrangle NURE HSSR study GJBX-95(78) report. This fact was noted in the REFORMAT comment field.

Water Records

  1. One well-water sample was found with an undefined value for WLDIST_M (Distance from well). This value was removed and added as a comment to the REFORMAT field.


Download The 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).

Notes for Data Users

The water samples were reportedly collected in the field without any filtering or acidification. (See the SAMPTYP coding explanation in the On-Line Manual for USGS-Reformatted NURE HSSR Data Files for descriptions of different Sample Types). However, the samples were filtered later in the laboratory through a 0.45 micron membrane filter before analysis. Therefore, the samples were not true "untreated water" samples and the analytical data may not be directly comparable for other quadrangle water samples of the same SAMPTYP when collected by a different laboratory. Since this was the standard procedure for Oak Ridge, water data from other Oak Ridge quadrangles should be comparable.

Latitude-longitude coordinates were reported in the original data files, as decimal degrees, to only 3 decimal places. Therefore, the precision of these coordinates is limited to +/- 0.001 degrees or +/- 3.6 seconds. This translates to a minimum precision of +/- 365 feet (111 m) for latitude values and between +/- 259 feet (79 m) to +/- 235 feet (72 m) for longitude values (calculated at latitudes of 45° and 50°N, respectively.)

One unusual sediment sample (identified as 'other sediment') collected in the Rice Lake quadrangle was not analyzed by any method.



Other NURE Geochemical Data for the Rice Lake Quadrangle

Rice Lake Quadrangle NURE Summary
An additional evaluation of the Rice Lake quadrangle was conducted by Derry, Michener & Booth under subcontract to Bendix Field Engineering Corporation [GJQ-006(81)]. As part of this study, 62 rock, 38 soil, 796 stream sediment, 196 lake sediment, and 202 ground water samples were collected within the Rice Lake quadrangle. All samples were analyzed for U by fluorometry; rock samples were also analyzed for As, Cu, Se, and V; and lake samples were additionally analyzed for As, Cu, Mo, Ni, Pb, Se, V, and Zn. These data were released only as appendices on microfiche accompanying the summary report. The results of this survey suggest that there are two areas, one north and one south, that are favorable for unconformity-related uranium deposits. This is based on empirical lithologic and structural recognition criteria. No uranium occurrences were found within the quad and none have been reported in previous literature.
