Movement of moisture in the unsaturated zone in a loess-mantled area, southwestern Kansas
Robert C. Prill
1977, Professional Paper 1021
A study of moisture movement associated with ponding near Garden City, Kansas, indicates that loess-manted areas have excellent potential for artificial recharge by water spreading. Infiltration stabilized at rates ranging from 0.7 to 2.2 feet (0.2 to 0.7 meter) per day reflecting changes in hydraulic conductivity of soil horizons. Results...
Late Quaternary depositional history, Holocene sea-level changes, and vertical crustal movement, southern San Francisco Bay, California
Brian F. Atwater, Charles W. Hedel, Edward J. Helley
1977, Professional Paper 1014
Sediments collected for bridge foundation studies at southern San Francisco Bay, Calif., record estuaries that formed during Sangamon (100,000 years ago) and post-Wisconsin (less than 10,000 years ago) high stands of sea level. The estuarine deposits of Sangamon and post-Wisconsin ages are separated by alluvial and eolian deposits and by...
Geohydrology of part of the Round Valley Indian Reservation, Mendocino County, California
K. S. Muir, Dwight Albert Webster
1977, Water-Resources Investigations Report 77-22
The Round Valley Indian Reservation in northern California obtains most of its water from the ground-water reservoir. The ground-water reservoir is made up of continental deposits, alluvium, and stream-channel deposits ranging in age from Pliocene to Holocene. Most of the water is pumped from the alluvium. Most ground water (about...
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...
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...
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...
