From abstract: Results of a reconnaissance geochemical survey of the Eau Claire Quadrangle, Wisconsin; Minnesota are reported. Field and laboratory data are presented for 565 groundwater samples, 680 stream sediment samples, and 667 stream water samples. Statistical and areal distributions of uranium and other possible uranium-related variables are displayed. A generalized geologic map of the survey area is provided and pertinent geologic factors which may be of significance in evaluating the potential for uranium mineralization are briefly discussed.

Quarterly report of the National Uranium Resource Evaluation Program Hydrogeochemical and Stream Sediment Survey documenting context related to the project, progress and results, plans for the next quarter, and other relevant information.

From abstract: Several low-level radiometric anomalies had been detected in an airborne survey of the Copper River Basin. This report presents the results of field and laboratory research on the origin of the anomalies, and the low radiometric background of the Copper River Basin.

Supplementary data containing radiometric readings of several locations to accompany a report on low-level airborne radiometric anomalies in the Copper River Basin Region, Alaska.

From abstract: Between mid-May and late June 1976, 3409 water and water-transported sediment samples were collected from 1781 locations spread over an approximate 17 000 kilometer area of northwestern Montana. All of the samples were analyzed for total uranium at the LASL, using standardized procedures and rigorous quality controls--the waters by fluorometry and the sediment (and those waters with >10 parts per billion uranium) by delayed-neutron counting methods.

From abstract: This report presents the results of the geochemical reconnaissance sampling in the Winnemucca 10 x 20 quadrangle of the National Topographic Map Series (NTMS). We collected wet and dry sediment samples throughout the 18,770-km2 arid to semi-arid area and water samples at available streams, springs and wells. We present neutron activation analyses of uranium and trace elements and other measurements made in the field and laboratory in tabular hardcopy and microfiche format. The report includes 5 full-size overlays for use with the Winnemucca NTMS 1:250,000 quadrangle. Water sampling sites, water-sample uranium and thorium concentrations, sediment sampling sites, and sediment-sample total uranium and thorium concentrations are shown on the separate overlays. We present general geological and structural descriptions of the area, and describe the 12 known uranium occurrences.

Supplementary data containing information on uranium concentrations in sediment samples to accompany a report on hydrogeochemical and stream sediment reconnaissance in the Winnemucca Quadrangle, Nevada.

From abstract: This report presents preliminary results of stream sediment and ground water reconnaissance in the Greensboro National Topographic Map Series (NTMS) 1° x 2° quadrangle. Stream sediment samples were collected from small streams at 1240 sites for a nominal density of one site per 13 square kilometers (five square miles) in rural areas. Ground water samples were collected at 774 sites for a nominal density of one site per 25 square kilometers (ten square miles).

Supplementary data including stream characteristics and additional elemental analyses to accompany a report on hydrogeochemcial and stream sediment reconnaissance in North Carolina, Virginia, and Tennessee.

The following report discusses the results of an evaluation of the uranium resource potential of the Seward Peninsula and Selawik area that was done in 1977.

From introduction: This report describes work done in the Noatak and portions of the Baird Mountains and Ambler River, Alaska, National Topographic Map Series (NTMS) quadrangles (1:250 000 scale) by the Los Alamos Scientific Laboratory (LASL) as part of the nationwide Hydrogeochemical and Stream Sediment Reconnaissance (HSSR).
