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 1,170 sediment and 1,127 water samples were collected from 1,175 locations in the Table Mountain quadrangle as part of the Los Alamos Scientific Laboratory (LASL) Table Mountain Quadrangle NURE Hydrogeochemical and Stream Sediment Reconnaissance (HSSR) study. Samples were collected during July and August of 1978. The sediment samples were analyzed by LASL for uranium and up to 43 additional elements, but LASL was unable to complete the Table Mountain 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-256(81) report. This report includes results for stream sediment samples only and does not give any details on the sample collection or analytical methods used for these samples.

LASL sent the 1,127 water samples from the Table Mountain 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-223(81) report.

Personnel of the U.S. Bureau of Mines, Alaska Field Operations Center, Fairbanks, collected 416 rock and 1,584 sediment samples "in 6 project areas in central and northeastern Alaska." The samples were sent to LASL for analysis (uranium and up to 42 other elements) and the results were released by Bendix Field Engineering Corporation of Grand Junction, Colo. in the GJBX-33(80) report. This report includes results for 38 rock samples and 53 sediment samples collected from within the Table Mountain quadrangle. However, the report does not include any site description data, and sample locations could only be identified on plates accompanying the report.

The following is a list of NURE sample types collected for these studies in the Table Mountain quadrangle.

*Summary of Table Mountain quadrangle sample types.*
Sediment Sample Type	Number of Samples	Water Sample Type	Number of Samples
Wet Streams	1,143	Streams	1,091
Dry Streams	44	Lakes	36
Wet Lakes	36
Total Sediments	1,223	Total Waters	1,127

These Table Mountain 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.
LA2: Los Alamos Energy Dispersive X-Ray Fluorescence Analysis of sediments for Ag, Bi, Cd, Cu, Nb, Ni, Pb, Sn, and W. (U.S. Bureau of Mines Study only.)
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.
LA4: Los Alamos Arc-Source Emission Spectrography Analysis of sediments for Be and Li. (U.S. Bureau of Mines Study only.)
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.)

Rock Samples

LA1: Los Alamos Delayed-Neutron Counting Analysis of rocks for U.
LA2: Los Alamos Energy Dispersive X-Ray Fluorescence Analysis of rocks for Ag, Bi, Cd, Cu, Nb, Ni, Pb, Sn, and W.
LA4: Los Alamos Arc-Source Emission Spectrography Analysis of rocks for Be and Li.
LA5: Los Alamos Neutron Activation Analysis of rocks 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.

Composition of the NEW-FORMAT NURE Data Files

The sediment data in the NEW-FORMAT NURE data files consist of 1,170 reformatted sediment records from the GJBX-256(81) LASL sediment data report and 53 reformatted sediment records from the GJBX-33(80) U.S. Bureau of Mines report. The water data in the NEW-FORMAT NURE data files consist of 1,127 reformatted water records from the GJBX-223(81) ORGDP water data report. The rock data consist of 38 reformatted rock records from the GJBX-33(80) U.S. Bureau of Mines report. Any changes in the data or problems found are noted in the REFORMAT comment field.

The site locations for samples from the U.S. Bureau of Mines studies were only identified on plates that accompanied the U.S. Bureau of Mines GJBX-33(80) report. These locations were digitized from the plates and the coordinates added to the sediment file. Occasionally, a sample site was plotted more than once or not at all. Problems with the coordinates for these samples 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).

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.

Values of 99999 are as reported in the GJBX publications and may reflect values above determination limits.

Sediment samples from the U.S. Bureau of Mines GJBX-33(80) report were assigned a SAMPTYP of 12 but no information was available on whether these samples were wet or dry.

Rock samples from the U.S. Bureau of Mines GJBX-33(80) report were crushed to <100 mesh and were assigned a SAMPTYP of 74.

Other NURE Geochemical Data for the Table Mountain 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.
