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 623 sediment and 605 water samples were collected from 639 locations during August and September of 1978 within the Christian quadrangle as part of the Los Alamos Scientific Laboratory (LASL) Christian 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 43 additional elements. When LASL was unable to complete the Christian 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-205(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 Christian quadrangle.

*Summary of Christian quadrangle sample types.*
Sediment Sample Type	Number of Samples	Water Sample Type	Number of Samples
Wet Streams	376	Streams	376
Dry Streams	24	Lakes	227
Wet Lakes	221	Springs	2
Wet Springs	2
Total Sediments	623	Total Waters	605

These Christian 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

LA6-FL: Los Alamos Fluorometry Analysis of waters for U.

Composition of the NEW-FORMAT NURE Data Files

The data in the NEW-FORMAT NURE data files consist of reformatted records from the GJBX-205(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).

Christian Quadrangle Sediment Data - 623 records
Christian Quadrangle Water Data - 605 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 Christian 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.
