National Geochemical Database—Reformatted Data from the National Uranium Resource Evaluation (NURE) Hydrogeochemical and Stream Sediment Reconnaissance (HSSR) Program

Version 1.40 (2006)

Brief History and Description of Data

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

Totals of 453 sediment and 547 water samples were collected from 550 locations during August of 1977 within the Iliamna quadrangle as part of the Los Alamos Scientific Laboratory (LASL) Iliamna Quadrangle NURE Hydrogeochemical and Stream Sediment Reconnaissance (HSSR) study. All samples were analyzed by LASL for uranium, and sediment samples were also analyzed for up to 42 additional elements. When LASL was unable to complete the Iliamna quadrangle data release report, the data were sent to the Bendix Field Engineering Corporation in Grand Junction, Colorado and subsequently published as the microfiche GJBX-89(81) report. This report does not give any details on the sample collection or analytical methods used for these samples.

The following is a list of NURE sample types collected in the Iliamna quadrangle.

Summary of Iliamna quadrangle sample types.
Sediment Sample Type Number of Samples Water Sample Type Number of Samples
Wet Streams (< 100 mesh) 147 Streams 165
Dry Streams (< 100 mesh) 1 Lakes 382
Wet Lakes (< 100 mesh) 303
Wet Lakes (< 80 mesh) 2
Total Sediments 453 Total Waters 547

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

Sediment Samples

Water Samples



Composition of the NEW-FORMAT NURE Data Files

The data in the NEW-FORMAT NURE data files consist of reformatted records from the GJBX-89(81) report. Any changes in the data or problems found 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).

Iliamna Quadrangle Sediment Data - 453 records
Iliamna Quadrangle Water Data - 547 records



Notes for Data Users

Water samples from this quadrangle are reported to have been acidified with nitric acid but NOT filtered in the field.



Other NURE Geochemical Data for the Iliamna Quadrangle

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.
