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...
The Permian and Triassic Seven Devils Group, western Idaho and northeastern Oregon
Tracy L. Vallier
1977, Bulletin 1437
Volcanogenic Permian and Triassic rocks in the Snake River Canyon of western Idaho and northeastern Oregon and in the adjacent Seven Devils Mountains of western Idaho are assigned to the Seven Devils Group. New rock-stratigraphic units are the Windy Ridge Formation of probable Early Permian age, the Hunsaker Creek Formation...
Ground-water resources and geology of Colquitt County, Georgia
E. A. Zimmerman
1977, Open-File Report 77-56
Limestone beds of Eocene, Oligocene, and lower Miocene age, called the principal artesian aquifer, are the chief source of ground water for Colquitt County. Because streams are small, undependable and relatively inaccessible to most users, ground water is the most important source for increased industrial and agricultural water use. Southeast...
Analysis of bottom material from the Willamette River, Portland Harbor, Oregon
Stuart W. McKenzie
1977, Open-File Report 77-740
The bottom material of the Willamette River, Portland Harbor, was sampled in duplicate on February 1, 1977. Results are reported on the following analyses of the material: immediate and long-term oxygen demand; particle size; percent moisture; residue, loss on ignition; and chemical....
Background studies for appraising subsidence in the Texas Gulf Coast region
B. E. Lofgren
1977, Open-File Report 77-412
Significant ground movement has accompanied the extraction of large quantities of fluids from the subsurface at many localities. The possibility of both horizontal and vertical ground movement--subsidence, fissuring, growth faulting--in the Gulf Coast region, caused by the withdrawal of large volumes of deep formation fluids, is of major concern.Although widespread...
Channel erosion surveys along the TAPS route, Alaska, 1977
Robert M. Loeffler, Joseph M. Childers
1977, Open-File Report 78-611
Channel surveys were made along the trans-Alaska pipeline system (TAPS) route during 1977 at the same 28 sites that were studied in 1976. In addition, a new site at pipeline mile 22 near Deadhorse (alignment No 134) along the Sagavanirktok River was put under surveillance. Except for changes wrought by...
Analyses of water, core material, and elutriate samples collected near Galliano, Louisiana: Larose to Golden Meadow, Louisiana, Hurricane Protection Project
Harold L. Leone
1977, Open-File Report 77-576
Seven core-material-sampling sites were chosen by the U.S. Army Corps of Engineers as possible borrow areas for fill material to be used in levee construction near Galliano La. Four receiving-water sites also were selected to represent the water that will contact the proposed levees. Analyses of selected nutrients, metals, pesticides,...
Analyses of water, core material, and elutriate samples collected near Buras, Louisiana (New Orleans to Venice, Louisiana, Hurricane Protection Project)
Harold A. Leone
1977, Open-File Report 77-310
Eight core-material-sampling sites were chosen by the U.S. Army Corps of Engineers as possible borrow areas for fill material to be used in levee contruction near Buras, La. Eleven receiving-water sites also were selected to represent the water that will contact the porposed levees. Analyses of selected nutrients, metals, pesticides,...
