Summary of references to mineral occurrences (other than mineral fuels and construction materials) in the Eagle Quadrangle, Alaska
Edward Huntington Cobb
1977, Open-File Report 77-845
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 Eagle quadrangle, Alaska. All references to reports of the Geological Survey, to most reports of the U.S. Bureau of Mines, and to most reports...
Elutriation study of Willamette River bottom material and Willamette-Columbia River water
Joseph F. Rinella, Stuart W. McKenzie
1977, Open-File Report 78-28
Bottom material from the Willamette River was collected and mixed with Willamette and Columbia River waters on May 17, 1977. The elutriate, as well as each sample, was analyzed for selected nutrients, metals, and pesticides. Results show that the average dissolved ammonia, manganese, and zinc concentrations would require dilution by...
Water-level records for the northern High Plains of Colorado, 1973-77
Thomas J. Major, Ronald G. Borman, Kenneth D. Vaught
1977, Open-File Report 77-160
Water-level measurements were made in more than 600 wells during January 1977 in the northern High Plains of Colorado which includes about 9,500 square miles. Most of these wells were irrigation wells, but several stock and government-owned wells were also measured, especially in areas where there is little irrigation. Changes...
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...
Summary of watershed conditions in the vicinity of Redwood National Park, California
Richard J. Janda
1977, Open-File Report 78-25
The Redwood Creek Unit of Redwood National Park is located in the downstream end of an exceptionally rapidly eroding drainage basin. Spatial distribution and types of erosional landforms, observed in the field and on time-sequential aerial photographs, measured sediment loads, and the lithologic heterogeneity of streambed materials indicated (1) that...
Lithium in the brines of Fish Lake Valley and Columbus Salt Marsh, Nevada
C. L. Smith, Allen L. Meier, H.D. Downey
1977, Open-File Report 77-54
Analyses of waters-from springs in Nevada have led to the identification of an area containing anomalous amounts of lithium northwest of the Clayton Valley-area. Fish Lake Valley and Columbus Salt Marsh contain waters having, relatively high lithium and potassium concentrations. At least a part of these waters is probably derived...
Reconnaissance drilling in the Yampa coal field, Hayden-Williams Fork Mountains area (Yampa No. 3), Moffat and Routt counties, Colorado, during 1976
Gary Prost
1977, Open-File Report 77-155
Under Contract No. 14-08-0001-15727, awarded by the U.S. Geological Survey, Jim Feighny, of Loveland, Colo., drilled 42 test holes in the Williams Fork Mountains near Hayden, Colo., in September 1976. The area is referred to in the Contract as Yampa No. 3, which includes the Bureau of Land Management's (ELM)...
Summary of hydrologic data collected during 1975 in Dade County, Florida
John E. Hull, T.R. Beaven
1977, Open-File Report 77-803
During the 1975 calendar year rainfall in Dade County, Fla., was 14.89 inches below the long-term average (57.17 in.). Ground-water levels ranged from 0.1 foot above to 1.1 feet below average. The highest and lowest ground-water levels for the year were both 1 foot below their long-term averages. In the...
Mineralogical, chemical, and physical properties of the regolith overlying crystalline rocks, Fairfax County, Virginia: a preliminary report
Gerhard W. Leo, M.J. Pavich, Stephen F. Obermeier
1977, Open-File Report 77-644
Undisturbed cores of saprolite developed on crystalline rocks of the Piedmont Province in Fairfax County, Virginia have been obtained using a combination of Shelby tubes, Denison sampler, and modified diamond core-drilling. The principal purpose of the core study is to correlate variations in chemistry, mineralogy and texture with engineering properties...
Genesis of a zoned granite stock, Seward Peninsula, Alaska
Travis Hudson
1977, Open-File Report 77-35
A composite epizonal stock of biotite granite has intruded a diverse assemblage of metamorphic rocks in the Serpentine Hot Springs area of north-central Seward Peninsula, Alaska. The metamorphic rocks include amphibolite-facies orthogneiss and paragneiss, greenschist-facies fine-grained siliceous and graphitic metasediments, and a variety of carbonate rocks. Lithologic units within the...
Preliminary assessment of the water resources of the Tulalip Indian Reservation, Washington
B. W. Drost
1977, Open-File Report 76-493
In 1974 about 30 percent of the nearly 600 acre-feet of water used on the Tulalip Indian Reservation was obtained from a surface-water reservoir, while nearly 70 percent was obtained from ground-water sources. Domestic use accounted for about 93 percent of total water use. Nutrient (phosphorus) concentrations measured in most...
Flood-plain delineation for Accotink Creek Basin, Fairfax County, Virginia
Pat L. Soule
1977, Open-File Report 76-442
Water-surface profiles of the 25-year and 100-year floods maps on which the 25-, 50-, and 100-year flood limits are delineated for streams in the Accotink Creek basin are presented in this report. Excluded are segments of Accotink Creek within the Fort Belvoir Military Reservation. The techniques used in the computation...
Application of remotely sensed land-use information to improve estimates of streamflow characteristics
Edward J. Pluhowski
1977, Open-File Report 77-632
Land-use data derived from high-altitude photography and satellite imagery are presented for 49 basins in Delaware, and eastern Maryland and Virginia. Based on 1:100,000 scale maps from high-altitude photography, basin land cover was extracted at the generalized Level I and the more detailed Level II classification categories. Level I land-use...
