Brief History and Description of Data

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

Totals of 1,280 sediment and 186 water samples were collected in the Caliente quadrangle between June and September of 1980 as part of the Savannah River Laboratory (SRL) Caliente Quadrangle NURE Hydrogeochemical and Stream Sediment Reconnaissance (HSSR) study. The water samples were analyzed by SRL for uranium and 9 other elements and then sent on to Oak Ridge Gaseous Diffusion Plant for "supplemental analyses" (31 elements in waters). SRL apparently did not analyze the sediment samples and subsequently did not release an individual quadrangle report for Caliente.

A total of 1,252 sediment samples from SRL were sent to the Oak Ridge Gaseous Diffusion Plant and analyzed for uranium and up to 31 additional elements. These data were released on microfiche by Oak Ridge as an abbreviated quadrangle report (GJBX-52(82)). The site coding information for Caliente quadrangle was summarized with several other western quadrangles in the Oak Ridge GJBX-51(82) report.

In 1982, ORGDP released the data from supplementary analyses of a selection of the SRL water samples from 4 eastern Nevada quadrangles in the GJBX-169(82) abbreviated report (on microfiche only). This report includes the supplemental data for up to 29 elements in 123 of the Caliente water samples. The site coding information for this data set was summarized in the GJBX-164(82) report.

In 1982, SRL released a summary report and data files for 50 quadrangles in the Western United States. For the Caliente quadrangle, this report (GJBX-132(82)) contains the SRL analytical data and the Oak Ridge supplemental data for water samples only. The sediment sample records only contained site information but no analytical values.

The following is a general listing of all sample types collected and reported for NURE studies in the Caliente quadrangle. The actual number of records in the NEW-FORMAT NURE data files may be greater because of the multiple records needed to preserve all the data.

Summary of Caliente quadrangle sample types.
Sediment Sample Type Number of Samples Water Sample Type Number of Samples
Dry Streams 971 Streams 11
Soils 254 Wells 41
Playa 35 Springs 134
Volcanic Neck 3
Other (may include mine tailings) 17
Total Sediments 1,280 Total Waters 186

These Caliente quadrangle samples were analyzed one or more of the following methods:

Composition of the NEW-FORMAT NURE Data Files

The data in the NEW-FORMAT NURE water data file consist of records from the GJBX-132(82) western U.S. summary report and the Oak Ridge GJBX-169(82) abbreviated report. In this file, the SRL analyses and supplemental analyses could NOT be combined because of overlapping determinations for 5 elements. Each water sample may therefore have 2 separate records - one for the SRL analysis and one for the supplemental analysis. The site information for every record in the GJBX-169(82) quadrangle report was checked against the "equivalent" record in the GJBX-132(82) western U.S. summary report and any major differences were noted in the REFORMAT comment field.

The data in the NEW-FORMAT NURE sediment file consist of records from both the GJBX-132(82) western U.S. summary report and the Oak Ridge GJBX-52(82) abbreviated report. Samples which had records in both reports were combined to create a single record for each sample. Problems noted in either of the original records are noted in the REFORMAT comment 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 websites, 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).

Caliente Quadrangle Sediment Data - 1,279 records
Caliente Quadrangle Water Data - 368 records

Notes for Data Users

Many records contain analytical values with insignificant digits. Most data should only have 2 or 3 significant digits. Differences after the second or third digit should be ignored.

Other NURE Geochemical Data for the Caliente Quadrangle

A report on the geology and mineral resources of the Caliente quadrangle prepared for the Savannah River Laboratory can be found in the GJBX-7(83) report. No geochemistry accompanies this report.
