Uranium Hydrogeochemical and Stream Sediment Reconnaissance of the Bozeman NTMS Quadrangle, Montana

Description: "This report describes work done in the Bozeman, Montana National Topographic Map Series (NTMS) quadrangle (1:250,000 scale) by the Hydrogeochemical and stream Sediment Reconnaissance (HSSR). The HSSR...is designed to identify areas having higher than normal concentrations of uranium in ground waters, surface waters, and water-transported sediments" (p. 1).

Uranium Hydrogeochemical and Stream Sediment Reconnaissance of the Moab NTMS Quadrangle, Utah/Colorado, Including Concentrations of Forty-Three Additional Elements

Description: Partial abstract: "During the summers of 1976, 1977, and 1978, 442 water and 1755 sediment samples were collected from 1801 locations within the 19 400 km2 area of the Moab quadrangle, Utah and Colorado, by private contractors for the Los Alamos Scientific Laboratory. Water samples were collected from streams, springs, and wells; wet and dry sediment samples were collected both from stream channels and from springs. Each water sample was analyzed for 13 elements, including uranium, and each sed… more

Uranium Hydrogeochemical and Stream Sediment Reconnaissance of the Albuquerque NTMS Quadrangle, New Mexico, Including Concentrations of Forty-Three Additional Elements

Description: Report of reconnaissance of the Albuquerque NTMS quadrangle through water and sediment samples collected from springs, wells, and streams. Samples analyzed for uranium and 42 other elements. This report is limited to samples containing uranium concentrations greater than the arbitrary anomaly thresholds of 5 parts per billion for waters and 6 parts per million for sediments.

Evaluated Neutron Cross Sections for Tritium

Description: From foreword: Evaluation of the experimental data on the light isotopes, hydrogen through beryllium, was initiated by LASL in mid-1963. Since the data compilations available were completely inadequate for the task at hand, the tedious program of compiling and plotting was undertaken. As the work progressed an attempt was made to eliminate many of the obvious errors and inconsistencies found in the literature and existing compilations.

Uranium Concentrations in Stream Waters and Sediments from Selected Sites in the Eastern Seward Peninsula, Koyukuk, and Charley River Areas, and Across South-Central Alaska

Description: During the summer of 1975, the Alaska Division of Geological and Geophysical Surveys (DGGS) conducted a 6-week reconnaissance in widespread areas of Alaska as part of the National Uranium Resource Evaluation (NURE) program sponsored by the Department of Energy (DOE). Water, stream sediment, and bedrock samples were taken from the eastern Seward Peninsula, from north of Koyukuk River, from the Charley River area, and from across south-central Alaska, to aid in determining the uranium potential o… more

Uranium Hydrogeochemical and Stream Sediment Reconnaissance in the San Juan Mountains, Southwest Colorado

Description: From 1995 sites in the San Juan Mountains area, 1706 water and 1982 sediment samples were collected during June-July 1976 and analyzed for uranium. The area includes the southern third of the Colorado mineral belt which has yielded rich ores of gold, silver, copper, lead, zinc, and molybdenum. The broadly domed mountains are capped by 2500 m of Tertiary volcanics, deeply eroded to expose a Precambrian crystalline core. Adjacent plateaus underlain by Mesozoic sedimentary rocks were included in t… more

Uranium Hydrogeochemical and Stream Sediment Reconnaissance in Lincoln and Flathead Counties, Northwest Montana

Description: 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.
