Eighty-three stream sites were selected for sampling in Eagle, Grand, Jackson, Pitkin, Routt, and Summit Counties. Also included are data from 28 sites...
Abundance and distribution of thorium in the carbonatite stock at Iron Hill, Powderhorn District, Gunnison County, Colorado
Theodore J. Armbrustmacher
1979, Open-File Report 79-536
The carbonatite stock at Iron Hill is part of an alkalic complex of Cambrian or latest Precambrian age containing pyroxenite, uncompahgrite, ijolite, nepheline syenite, and related rocks characterized by their subsilicic composition and by their lack of calcic plagioclase. Thorium averages 36.2 parts per million (ppm) Th (0.0041 percent Th02)...
Ground-water conditions and potential for artificial recharge in Lucerne Valley, San Bernardino County, California
Donald H. Schaefer
1979, Water-Resources Investigations Report 78-118
The water level in two areas of Lucerne Valley has declined more than 100 feet since 1917, including 60 feet from 1954 to 1976. These declines are the result of pumping for the irrigation of alfalfa. The lowering of water levels has caused many shallow domestic wells to go dry....

A uranium occurrence in the Tertiary Kootznahoo Formation on Kuiu Island, southeast Alaska
Kendell A. Dickinson
1979, Open-File Report 79-1427
Radioactive anomalies as high as 50 times background and uranium-bearing samples were discovered in parts of the nonmarine Tertiary Kootznahoo Formation in southeast Alaska by K. A. Dickinson and John Mitchell. Samples containing as much as 1300 ± 400 ppm uranium, measured by beta eU, were found. These samples have...
Possible reestablishment of sawtimber production following mining in the Osceola National Forest, an analysis of the state-of-the-art, February 9, 1978
J. Scott Boyce
1979, Open-File Report 79-524
There is a good possibility that sawtimber production could be reestablished on the Osceola National Forest. Engineering technology that is coming on-line should allow the establishment of land/water relationships that meet the requirements of desired tree species. Information available on soil-plant relationships indicate an absence of phytotoxic materials in various...
Particulate organic carbon in San Francisco Bay, California, 1971-1977
Laurence E. Schemel, Lee A. Dedini
1979, Open-File Report 79-512
The organic-carbon content of suspended particulate matter is determined by wet oxidation and analysis of the resulting CO2 with an infrared analyzer. Modifications of methods and improved designs of apparatus are presented.Results of particulate organic carbon (POC) analyses from 1971 through 1977 show that concentrations in North San Francisco Bay...

David B. Grove, Ronald L. Miller, Leonard F. Konikow, P. S. O’Boyle
1979, Open-File Report 79-700
Data showing results of 38 groundwater and 25 surface-water samples analyzed for hexavalent chromium are presented. Most samples were taken within the Telluride, Colo., city limits during October 1978. Twenty-four of the 38 groundwater samples (63%) contained more than 50 micrograms per liter of hexavalent chromium. Excluding the mill tailings...
Helium in soil-gas and helium/radon in ground water in the vicinity of a south Texas uranium roll-type deposit
G. Michael Reimer, C.G. Bowles, D.G. Murrey, J.M. Been
1979, Open-File Report 79-1625
A survey was run in the vicinity of a south Texas uranium roll-type deposit to determine the general concentration of helium in the soil gas and helium/radon ratios in the ground water for deposits of this nature. The helium in soil-gas concentrations are typical of the concentrations found associated with...
Chemical correlation of some late Cenozoic tuffs of Northern and Central California by neutron activation analysis of glass and comparison with X-ray fluorescence analysis
Andrei M. Sarna-Wojcicki, Harry W. Bowman, Paul C. Russell
1979, Professional Paper 1147
Glasses separated from several dacitic and rhyolitic late Cenozoic tuffs of northern and central California were analyzed by neutron activation for more than 43 elemental abundances. Eighteen elements--scandiurn, manganese, iron, zinc, rubidium, cesium, barium, lanthanum, cerium, samarium, europium, terbiurn, dysprosiurn, ytterbiurn, hafniurn, tantalurn, thorium and uranium--were selected as most suitable...
Ground-water quality in Bannock, Bear Lake, Caribou, and part of Power counties, southeastern Idaho
Harold R. Seitz, Ralph F. Norvitch
1979, Water-Resources Investigations Report 79-14
This report provides information about the current quality of ground waters in southeastern Idaho and discusses the natural and manmade environmental controls on that quality. This information will be useful in planning and monitoring the development and use of the ground-water resources of southeastern Idaho.The southeastern corner of Idaho, as...

Late diagenetic indicators of buried oil and gas: II, Direct detection experiment at Cement and Garza oil fields, Oklahoma and Texas, using enhanced LANDSAT I and II images
Terrence J. Donovan, Patricia A. Termain, Mitchell E. Henry
1979, Open-File Report 79-243
The Cement oil field, Oklahoma, was a test site for an experiment designed to evaluate LANDSAT's capability to detect an alteration zone in surface rocks caused by hydrocarbon microseepage. Loss of iron and impregnation of sandstone by carbonate cements and replacement of gypsum by calcite are the major alteration phenomena...
