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

Brief History and Description of Data

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

Totals of 7 sediment and 7 water samples were collected from 7 locations in the Atlin quadrangle as part of the Los Alamos Scientific Laboratory (LASL) Atlin Quadrangle NURE Hydrogeochemical and Stream Sediment Reconnaissance (HSSR) study. Samples were collected during July and September of 1979. The sediment samples were analyzed by LASL for uranium and up to 43 additional elements, but LASL was unable to complete the Atlin quadrangle data release report. The sediment data were sent to and released by the Bendix Field Engineering Corporation in Grand Junction, Colorado only as a microfiche GJBX-17(82) report. This report does not give any details on the sample collection or analytical methods used on these samples.

LASL sent the 7 water samples from the Atlin 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-166(81) report.

The following is a list of NURE sample types collected within the Atlin quadrangle.

Sediment Sample Type	Number of Samples	Water Sample Type	Number of Samples
Wet Streams	6	Streams	6
Wet Lakes	1	Lakes	1
Total Sediments	7	Total Waters	7

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

Sediment Samples

LA1: Los Alamos Delayed-Neutron Counting Analysis of sediments for U.
LA3: Los Alamos Energy Dispersive X-Ray Fluorescence Analysis of sediments for Ag, As, Bi, Cd, Cu, Nb, Ni, Pb, Se, Sn, W and Zr.
LA5: Los Alamos Neutron Activation Analysis of sediments for Al, Au, Ba, Ca, Ce, Cl, Co, Cr, Cs, Dy, Eu, Fe, Hf, K, La, Lu, Mg, Mn, Na, Rb, Sb, Sc, Sm, Sr, Ta, Tb, Th, Ti, V, Yb, and Zn.

Water Samples

OR9-FL: Oak Ridge Fluorescence Spectroscopy Analysis of waters for U.
OR9-MS: Oak Ridge Mass Spectrometry Analysis of waters for U.
OR13: Oak Ridge Emission Spectrochemical Analysis of waters for Ag, Al, B, Ba, Be, Ca, Ce, Co, Cr, Cu, Fe, K, Li, Mg, Mn, Mo, Na, Ni, P, Sc, Si, Sr, Ti, V, Y, Zn, and Zr. (Note: Nb and Th may be included in this method.)

Composition of the NEW-FORMAT NURE Data Files

The data in the NEW-FORMAT NURE data files consist of 7 reformatted sediment records from the GJBX-17(82) report and 7 reformatted water records from the GJBX-166(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).

Atlin Quadrangle Sediment Data - 7 records
Atlin Quadrangle Water Data - 7 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.

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.

Other NURE Geochemical Data for the Atlin 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.
