Brief History and Description of Data

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

The responsibility for the Salt Lake City Quadrangle NURE Hydrogeochemical and Stream Sediment Reconnaissance (HSSR) study was assigned first to the Lawrence Livermore Laboratory and later to the Savannah River Laboratory. As far as has been determined, no HSSR samples were collected or analyzed from the Salt Lake City quadrangle.

In October and November of 1979, 988 sediment, 86 water, and 391 rock samples were collected by Oak Ridge in Utah for the Thomas Range-Wasatch detailed geochemical survey. Three project areas were chosen to "characterize the hydrogeochemistry, stream sediment geochemistry, and/or radiometric patterns of known or potential uranium occurrences." These three areas were (1) the Thomas Range-Sheeprock Mountain project area within the Delta 1° x 2° quadrangle; (2) the Farmington project area covering parts of the Brigham City, Ogden, and Salt Lake City quadrangles; and (3) the Cottonwood project area within the Salt Lake City quadrangle. A total of 127 sediment, and 22 water samples were collected and field radiometric data were reported for 121 rock samples within the Salt Lake City quadrangle. The radiometric readings of rock samples were done in the field using scintillometers and a gamma-ray spectrometer. The sediment and water samples were analyzed for multiple elements by Oak Ridge and the data were reported in the 3-volume Thomas Range-Wasatch Detailed Study GJBX-238(80) report.

A list of geologic unit codes and explanations used for the Thomas Range-Wasatch Detailed Study was obtained from Table 4 and Figure 3 in the each of the 3 volumes of the GJBX-238(80) report and reproduced here. These codes are found in the SGEOUNIT and PUNIT fields for each record in the NEW-FORMAT NURE data files.

Composition of the NEW-FORMAT NURE Data Files

The data in the NEW-FORMAT NURE data files consist of records from the Salt Lake City quadrangle portion of the Thomas Range-Wasatch Detailed Study GJBX-238(80) report. Any problems found during the reformatting process are noted in the REFORMAT comment field.

Data from the rock samples were placed in a separate data file. A partial description of fields unique to this file is given below in the Thomas Range-Wasatch Detailed Study rock data format. Analyses for phosphate in water were also found in the Detailed Study data. This information can be found in another separate file and a partial description of fields unique to this file is given below in the Thomas Range-Wasatch Detailed Study extra water data format.



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).

Notes for Data Users

The ORGDP Thomas Range-Wasatch Detailed Study water samples were reportedly collected without any filtering or acidification. (See the SAMPTYP coding explanation in the On-Line Manual for New-Format NURE HSSR Data Files for descriptions of different Sample Types). However, these ORGDP 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 and may not be comparable to the LASL water samples which have a different SAMPTYP. Since this was the standard procedure for Oak Ridge, water data from other Oak Ridge studies should be comparable.

Latitude-longitude coordinates were reported in the original Thomas Range-Wasatch Detailed Study 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 +/- 280 feet (85 m) to +/- 259 feet (79 m) for longitude values (calculated at latitudes of 40° and 45°N, respectively.)



Other NURE Geochemical Data for the Salt Lake City Quadrangle

Research Associates of Wyoming conducted the Uinta Arch Project to "assess the favorability of Precambrian metasedimentary rocks in northern Utah for deposits of uranium in Precambrian quartz-pebble conglomerates" [GJBX-170(80)]. During this study, 380 rock samples were collected and analyzed from 5 project areas: (1) Red Creek area, Vernal quadrangle (192 rocks); (2) Farmington area, Salt Lake City quadrangle (76 rocks); (3) Little Willow area, Salt Lake City quadrangle (28 rocks); (4) Antelope Island area, Tooele quadrangle (31 rocks); and (5) Facer Creek area, Ogden quadrangle (53 rocks). Field and analytical data were released only as appendices to this report.
