Ground-water data for the Drewsey Resource Area, Harney and Malheur counties, Oregon
Joseph B. Gonthier, C. A. Collins, David B. Anderson
1977, Open-File Report 77-741
Appraisals of the resources of selected management areas in eastern Oregon are being made by the U.S. Bureau of Land Management. To provide needed hydrologic information the Bureau of Land Management requested the U.S. Geological Survey Water Resources Division to inventory ground-water data for the Drewsey Resource Area. Included in...
Geochemical and mineralogical studies of a South Texas roll-front uranium deposit
Martin B. Goldhaber, Richard L. Reynolds
1977, Open-File Report 77-821
Core samples from a roll-front uranium deposit in south Texas have been analyzed for iron sulfide content and mineralogy, organic carbon content and the abundance of carbonate, iron, manganese and titanium. Sulfide occurs almost exclusively as the iron disulfides pyrite and marcasite, in concentrations as high as 2 percent of...
Mineral resources of the Sheep Mountain Wilderness study area and the Cucamonga Wilderness and additions, Los Angeles and San Bernardino counties, California
James G. Evans, Leroy Pankraatz, James Ridenour, Steven W. Schmauch, Nicholas T. Zilka
1977, Open-File Report 77-251
A mineral survey of the Sheep Mountain Wilderness study area and Cucamonga Wilderness area and additions by the U.S. Geological Survey and Bureau of Mines in 1975 covered about 66,500 acres (26,500 ha) of the San Bernardino and Angeles National Forests in southern California. The two study areas are separated...
A FORTRAN program for calculating nonlinear seismic ground response
William B. Joyner
1977, Open-File Report 77-671
The program described here was designed for calculating the nonlinear seismic response of a system of horizontal soil layers underlain by a semi-infinite elastic medium representing bedrock. Excitation is a vertically incident shear wave in the underlying medium. The nonlinear hysteretic behavior of the soil is represented by a model...
Mineral occurrences (other than mineral fuels and construction materials) in the Bethel, Goodnews and Russian Mission quadrangles, Alaska
Joseph McCormick Hoare, Edward Huntington Cobb
1977, Open-File Report 77-156
These summaries of references are designed to aid in library research on metallic and nonmetallic (other than mineral fuels and construction materials) mineral occurrences in the Bethel, Goodnews, and Russian Mission quadrangles in southwestern Alaska. All references to reports of the Geological Survey, to most reports of the U.S. Bureau...
Hydrogeologic data for the McKay Creek subsurface waste-injection test site, Pinellas County, Florida
John D. Hickey
1977, Open-File Report 77-802
Lithologic, hydraulic, geophysical, and water-quality data collected at the McKay Creek subsurface waste-injection test site in Pinellas County, Florida, are reported. Data were collected to determine the possibility of subsurface injection of waste-treatment plant effluent. One exploratory hole, one test injection well, and eight observation wells were constructed between May...
Mapping the lateral boundaries of a cooling basaltic lava lake, Kilauea Iki, Hawaii
Vincent J. Flanigan, Charles J. Zablocki
1977, Open-File Report 77-94
Two types of electromagnetic (EM) profiling techniques were used to delineate the surface projection of the edges of the still-molten basaltic lava lens that exists in Kilauea Iki Crater, Hawaii. These studies were made as part of an intensive geophysical program aimed at defining the overall configuration of the liquid...
Uranium mobility during interaction of rhyolitic glass with alkaline solutions: dissolution of glass
Robert A. Zielinski
1977, Open-File Report 77-744
This report concerns investigations designed to identify the important physical and chemical parameters influencing the rate of release of uranium from glass shards of rhyolitic air-fall ash. Oxidizing, silica undersaturated, alkaline solutions are eluted through a column of rhyolitic glass shards at a carefully controlled temperature, pressure, and flow rate....
Hydrologic data for North Creek, Trinity River basin, Texas, 1975
C.C. Kidwell
1977, Open-File Report 76-724
This report contains the rainfall, runoff, and storage data collected during the 1975 water year for the 21.6-square-mile area above the stream-gaging station North Creek near Jacksboro, Texas. The weighted-mean rainfall in the study area during the water year was 39.01 inches, which is greater than the 18-year average of...
Nitrogen in water in Nassau and Suffolk counties, Long Island, New York, in 1971
Brian G. Katz, Stephen E. Ragone, C. Albert Harr
1977, Open-File Report 77-433
The concentration of inorganic nitrogen was measured in samples from 521 wells in the upper glacial and Magothy aquifers and from 46 streams in Nassau and Suffolk Counties during May 1971. The predominant form of dissolved nitrogen was nitrate. Nitrate concentrations (as N) in the upper glacial aquifer in both...
Quantity and quality of drainage from the Argo Tunnel and other sources related to metal mining in Gilpin, Clear Creek and Park Counties, Colorado
Dennis A. Wentz
1977, Open-File Report 77-734
Eighteen metal-mine drainage sources have been located in that part of Gilpin, Clear Creek, and Park Counties, Colo., lying within the Missouri River basin. At least 13 of these sources are known to contain high acidity and (or) trace-element concentrations or to contribute water to adversely affected streams. From January...
Mapping luminescence of uranium-bearing sandstones using an imaging Fraunhofer line discriminator
Robert D. Watson, Arnold F. Theisen
1977, Open-File Report 77-743
Measurements with a Fraunhofer Line Discriminator (FLD) imaging system over uranium-bearing sandstones in the Galisteo Formation, Sandia Mountains, New Mexico, show that luminescence of these sandstones is detectable and in general agreement with their distribution as mapped on the ground. The FLD imaging system coupled with a color television monitor...
