Quaternary stratigraphic sections with radiocarbon dates, Wiseman Quadrangle, Alaska
Thomas D. Hamilton
1980, Open-File Report 80-791
The Wiseman quadrangle contains a rich stratigraphic record of alluvial, glacial, and periglacial events of the late Quaternary in the south-central Brooks Range. The numerous bluffs along the Koyukuk River and its tributaries expose drift sheets of the late Pleistocene Itkillik I glacial phase (table 1), and outwash and other...

Catalog of earthquakes in the Yellowstone Park - Hebgen Lake region from November 1972 to December 1975
A.D. Pitt
1980, Open-File Report 80-2006
The U.S. Geological Survey (USGS) began operating a network of seismograph stations in Yellowstone Park in 1964. The stations were self-contained and their locations were limited by the necessity for year-round access, 110-volt power, and a light-tight recording area. The network had a maximum of 5 permanent stations and was...

1980, Open-File Report 80-187
The Seismic Research Observatory (SRO) network is generating an important new data base for seismological research. The SRO systems have extended both the range and resolution of seismic measurements beyond the limits of conventional seismographs and the data are recorded in digital format making it convenient to automate processing and...
Lemhi Pass drilling project, Montana
Mortimer Hay Staatz
1980, Open-File Report 80-312
The Lemhi Pass district has the largest thorium resources of any vein district in the United States (Staatz and others, 1979, p. 10). Most of the resources occur in veins that have an average grade of between 0.1 and 2.0 percent Th02. More than 200 thorium-bearing veins have been mapped...

U.S. Geological Survey role in earthquake prediction
David P. Hill
1980, Open-File Report 80-144
Work in the Seismology Branch on the problem of earthquake prediction is based primarily on the recording and analysis of seismic (elastic) waves in the Earth generated either by earthquakes themselves or by artificial sources such as quarry blasts or explosions detonated in drill holes. At the present time this...

A preliminary appraisal of the effects of agriculture on stream quality in southwest Georgia
Dean B. Radtke, James B. McConnell, William P. Carey
1980, Open-File Report 80-771
Water—quality and suspended—sediment samples were collected in two basins in southwest Georgia to determine whether water—quality problems have resulted from agricultural practices. Samples were collected monthly and during periods of storm runoff from December 1976 through July 1978. Concentrations of chemical constituents relevant to agricultural practices were found to be...

Seismic evidence for an extensive gas-bearing layer at shallow depth, offshore from Prudhoe Bay, Alaska
Gary Wynn Boucher, Erk Reimnitz, Edward W. Kempema
1980, Open-File Report 80-809
High resolution seismic reflection data recorded offshore from Prudhoe Bay, Alaska, were processed digitally to determine the reflectivity structure of the uppermost layers of the seafloor. A prominent reflector found at 27 m below the mudline (water depths 7-9 m) has a negative reflection coefficient greater than 0.5. The large...
In-situ measurements of seismic velocity at 27 locations in the Los Angeles, California region

1980, Open-File Report 80-378
Studies conducted in the San Francisco Bay Region (Gibbs, Fumal and Borcherdt, 1980) have shown that average shear-wave velocity can be readily tied to quantitative estimates of ground motion such as ground amplification and earthquake intensity. Furthermore, when certain physical properties of the geologic materials such as texture, hardness and...
