[See History of NURE HSSR Program for a summary of the entire program.]
Totals of 1,956 sediment and 1,108 water samples were collected from 1,999 locations in the Wyoming portion of Driggs, Preston, and Ogden quadrangles during September and October of 1976. These samples were collected by a private contractor under the direction of the Los Alamos Scientific Laboratory (LASL). Within the Preston quadrangle, 707 sediment and 461 water samples were collected. The samples were analyzed by LASL for uranium and the data released in the GJBX-70(78) report.
LASL sent 702 sediment and 410 water samples from the Wyoming portion of the Preston quadrangle to the Oak Ridge Gaseous Diffusion Plant for multielement analyses. These data were released by Oak Ridge as the Preston Quadrangle NURE Hydrogeochemical and Stream Sediment Reconnaissance (HSSR) study GJBX-325(81) report.
In 1977, the entire NURE HSSR program changed from a study area basis (State, County, or geomorphic province) to a 1° x 2° quadrangle basis. As a result of this decision, the responsibility for the Idaho portion of the Preston quadrangle was reassigned to the LASL. According to the last LASL NURE progress report [GJBX-5(80)], this area was scheduled to be sampled during 1980. Apparently though, no samples for this Idaho area were subsequently collected or analyzed by LASL before the NURE program ended.
The following is a list of sample types collected for the Preston quadrangle study.
Sediment Sample Type | Number of Samples | Water Sample Type | Number of Samples |
---|---|---|---|
Wet Streams | 370 | Streams | 373 |
Dry Streams | 247 | Wells | 21 |
Wet Springs | 60 | Springs | 54 |
Wet Natural Ponds | 4 | Natural Ponds | 4 |
Wet Artificial Ponds | 10 | Artificial Ponds | 9 |
Dry Artificial Ponds | 16 | ||
Total Sediments | 707 | Total Waters | 461 |
These Preston quadrangle samples were analyzed by one or more of the following methods:
Sediment Samples
Water Samples
The data in the NEW-FORMAT NURE data files consist of records from the GJBX-70(78) report combined with records from the GJBX-325(81) report. Each sample is represented by a single composite record. Any problems found during the reformatting process are noted in the REFORMAT comment field.
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).
Preston Quadrangle Sediment Data - 707 records
Preston Quadrangle Water Data - 461 records
The Bendix Field Engineering Corporation conducted a study of three topaz-bearing rhyolite domes north of Soda Springs, Idaho in the Preston quadrangle. Eight rock samples were collected and analyzed for eK, eU, and eTh by closed-can gamma-ray spectroscopy and were also analyzed for several additional elements using emission spectroscopy, atomic absorption, X-ray fluorescence, fluorometry, inductively coupled plasma spectroscopy, ion selective electrode, and wet chemical techniques. Sample descriptions and analytical values are found only as tables in the published GJBX-1(84) report.
The Bendix Field Engineering Corporation identified and ranked 269 uranium anomalies from 23 quadrangles in and adjacent to Wyoming. These anomalies were based on an evaluation of the NURE HSSR data, aerial radiometric reconnaissance surveys and, to a lesser extent, geologic evaluations. This report [GJBX-3(83)] lists 3 uranium anomalies that were identified in the Preston quadrangle. No additional data for any samples accompanies this report.
