[See History of NURE HSSR Program for a summary of the entire program.]
During the summer of 1975, the Alaska State Department of Natural Resources, Division of Geological and Geophysical Surveys (DGGS), conducted a uranium reconnaissance study within 13 Alaska quadrangles. From this study, 644 sediment and 601 water samples collected from 694 locations were sent to the Los Alamos Scientific Laboratory (LASL) for analysis. LASL analyzed these samples for uranium and the analytical data were released in the GJBX-79(78) report. This report includes results for 34 sediment samples and 32 water samples collected from 37 locations within the Hughes quadrangle.
Totals of 636 sediment and 637 water samples were collected from 640 locations in the Hughes Quadrangle as part of the LASL Hughes Quadrangle NURE Hydrogeochemical and Stream Sediment Reconnaissance (HSSR) study. Samples were collected during June and July of 1978. The sediment samples were analyzed by LASL for uranium and up to 43 additional elements, but LASL was unable to complete the Hughes quadrangle data release report. The data were sent to and released by the Bendix Field Engineering Corporation in Grand Junction, Colorado only as a microfiche GJBX-258(81) report. This report does not give any details on the sample collection or analytical methods used for these samples.
LASL sent the 637 water samples from the Hughes quadrangle to the Oak Ridge Gaseous Diffusion Plant (ORGDP) for analysis. These samples were analyzed for uranium and up to 27 additional elements and the results were released by ORGDP in the GJBX-158(81) report.
The following is a list of NURE sample types collected for these studies in the Hughes quadrangle.
| Sediment Sample Type | Number of Samples | Water Sample Type | Number of Samples |
|---|---|---|---|
| Wet Streams (< 100 mesh) | 441 | Streams | 472 |
| Wet Streams (< 80 mesh) | 30 | Lakes | 195 |
| Dry Streams (< 80 mesh) | 4 | Springs | 2 |
| Wet Lakes (< 100 mesh) | 193 | ||
| Wet Springs (< 100 mesh) | 2 | ||
| Total Sediments | 670 | Total Waters | 669 |
These Hughes quadrangle samples were analyzed by one or more of the following methods:

Water Samples
The sediment data in the NEW-FORMAT NURE data files consist of 636 reformatted sediment records from the GJBX-258(81) LASL sediment data report and 34 reformatted sediment records from the GJBX-79(78) DGGS report. The water data in the NEW-FORMAT NURE data files consist of 637 reformatted water records from the GJBX-158(81) ORGDP water data report and 32 reformatted water records from the GJBX-79(78) DGGS report. Any changes in the data or problems found are noted in the REFORMAT comment field.
The data files are in dBase IV .dbf format. A complete description of the data fields and coding schemes is available online - On-Line Manual for New-Format NURE HSSR Data Files.

Water samples from this quadrangle are reported to have been acidified with nitric acid but NOT filtered in the field.
The ORGDP fluorometric procedure for uranium required each water sample to be centrifuged before taking an aliquot for analysis. It is not clear whether water samples analyzed by emission spectrometry were also centrifuged prior to analysis.
LASL compiled all of the regional HSSR data from Alaskan NURE studies and produced a report [GJBX-32(83] that graphically displays the distribution of selected elements for most of the State. No additional geochemical data were released with this report.
