[See History of NURE HSSR Program for a summary of the entire program.]
Totals of 667 sediment and 671 water samples were collected at 675 locations in the Lime Hills quadrangle using standardized field procedures developed by the Los Alamos Scientific Laboratory (LASL) during August - September of 1977 as part of the Hydrogeochemical and Stream Sediment Reconnaissance (HSSR) phase. LASL analyzed the samples for uranium and other elements (42 additional elements in sediments and 12 additional elements in waters), and released the data in the GJBX-29(79) report.
The following is a list of sample types collected for the Lime Hills quadrangle study.
Sediment Sample Type | Number of Samples | Water Sample Type | Number of Samples |
---|---|---|---|
Wet Streams | 271 | Streams | 270 |
Dry Streams | 3 | Lakes | 401 |
Wet Lakes | 393 | ||
Total Sediments | 667 | Total Waters | 671 |
These Lime Hills 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 reformatted records from the GJBX-29(79) report. Any problems found during the reformatting process are noted in the REFORMAT comment field.
Values for dissolved oxygen in 526 samples were added from a table in the GJBX-29(79) report and can be found in the O_DISS 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).
Lime Hills Quadrangle Sediment Data - 667 records
Lime Hills Quadrangle Water Data - 671 records
Water samples from this quadrangle are reported to have been acidified with nitric acid but NOT filtered in the field.
A summary evaluation report was prepared for the Lime Hills quadrangle by C.C. Hawley and Associates of Anchorage, Alaska [PGJ/F-057(82)]. Additional samples of 471 stream sediments, 200 rocks, and 4 panned concentrates were collected in the quadrangle to "identify geologic environments favorable for the occurrence of uranium deposits." All of the stream sediment and rock samples were analyzed for uranium oxide by fluorometry and 111 of the stream sediment samples, 46 of the rock samples, and the 4 panned concentrates were analyzed for 29 additional elements by semi-quantitative emission spectrography. The panned concentrates were also analyzed for uranium oxide and Th by unspecified methods. These data were released only as microfiche appendices accompanying the summary report.
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.
