Profiles showing potentiometric surfaces and changes in effective stress in aquifers in Harris and Galveston counties, Texas, 1977-78
R.K. Gabrysch
1978, Open-File Report 78-299
These profiles were prepared by the U.S. Geological Survey in cooperation with the Harris-Galveston Counties Coastal Subsidence District and the Texas Department of Water Resources to show the changes in the altitudes of the potentiometric surfaces and, consequently, the changes in effective stress on the framework of the aquifers as...
Geotechnical properties of sediments from the Continental Shelf south of Icy Bay, northeastern Gulf of Alaska
Paul R. Carlson, William P. Levy, Bruce F. Molnia, John C. Hampson Jr.
1978, Open-File Report 78-1071
Studies of geotechnical properties of marine sediments have recently intensified as the search for natural resources has expanded on the continental shelf. The U. S. Geological Survey has begun a detailed evaluation of geologic environmental conditions in continental shelf regions in order to facilitate safe development of continental shelf resources....
Mineral resources of the Charles Sheldon wilderness study area, Humboldt and Washoe Counties, Nevada, and Lake and Harney Counties, Oregon
John B. Cathrall, R. C. Greene, Donald Plouff, D. F. Siems, G. L. Crenshaw, E.F. Cooley, E.T. Techek, F.J. Johnson, M. D. Conyac
1978, Open-File Report 78-1002
A mineral survey of the Charles Sheldon wilderness study area, located in Humboldt and Washoe Counties, Nevada, and Lake and Harney Counties, Oregon was conducted in 1974 and 1975 (fig. 1A, 1B, 1C). The mineral resource potential was evaluated by geological, geochemical, and geophysical studies by the U.S. Geological Survey,...
Ground-water levels and quality data for Georgia, 1977
Water Resources Division, U.S. Geological Survey
1978, Open-File Report 79-213
This report begins a publication format that will present annually both water-level and water-quality data. In this format the information is presented in two-page units: the left page includes text which summarizes the information for an area or subject and the right page consists of one or more illustrations. Daily...
Chemical and biological quality of Lakes Faith, Hope, and Charity at Maitland, Florida, with emphasis on the effects of storm runoff and bulk precipitation, 1971-1974
Neville G. Gaggiani, A. G. Lamonds
1978, Open-File Report 77-491
Located in a closed basin, near Orlands, Fla., Lake Faith, Hope, and Charity cover a combined area of 132 acres and are surrounded by residential, citrus grove and undeveloped areas. All of these areas affect the water quality of the lakes through storm runoff and transport of windborne material. During...
Radioactive anomaly and mineralogy of the lower part of the Tabuk Formation, Al Qassim area, Kingdom of Saudi Arabia
John J. Matzko, V. J. Flanigan, Mustafa Mawad, Ziad Al Kollak, M.I. Naqvi, Abdul Malik Helaby
1978, Open-File Report 78-520
A radioactive anomaly about 10 km long was detected by an airborne survey of the Tabuk Formation, about 75 km west-northwest of Buraydah in northeastern Saudi Arabia. The gamma-spectrometer anomaly is 6 to 10 times higher than background over the adjacent Precambrian shield area and indicates anomalous concentrations of thorium-bearing...
Proceedings of Conference III: fault mechanics and its relation to earthquake prediction, convened under the auspices of National Earthquake Hazards Reduction Program, 1-3 December, 1977
Water Resources Division, U.S. Geological Survey
1978, Open-File Report 78-380
On 1 - 3 December 1977, a Conference on "Fault Mechanics and Its Relation to Earthquake Prediction" was held at Stanford University, Stanford, California. This Conference was the third in a continuing series of Conferences to be held under the auspices of the Earthquake Hazards Reduction Program. These Conferences and publication of their proceedings are...
Proceedings of Conference V: communicating earthquake hazard reduction information: convened under auspices of National Earthquake Hazards Reduction Program 22-24 May, 1978
Walter W. Hays
1978, Open-File Report 78-933
Under the Earthquake Hazard Reduction Act of 1977, the federal government is significantly increasing its effort "to reduce the risk of life and property from future earthquakes in the United States through the establishment and maintenance of an effective earthquake hazards reduction program". This prgoram is sponsored primarily by the...
Proceedings of Conference VI: Methodology for identifying seismic gaps and soon-to-break gaps: Convened under auspicies of National Earthquake Hazards Reduction Program, 25-27 May, 1978
Bryan L. Isacks, George Plafker
1978, Open-File Report 78-943
The fifth conference in the continuing series under the Earthquake Hazard Reduction Program was held at Massachusetts Institute of Technology on May 25- 27, 1978. Its theme was "Methodology for Defining Seismic Gaps and Soon-to-Break Seismic Gaps." One of the proposed strategies for acquiring critical data on earthquake prediction is...
Playback Station #2 for Cal Net and 5-day-recorder tapes
Jerry P. Eaton
1978, Open-File Report 78-542
A second system (Playback Station #2) has been set up to play back Cal Net 1" tapes and 5-day-recorder 1/2" tapes. As with the first playback system (Playback Station #1) the tapes are played back on a Bell and Howell VR3700B tape deck and the records are written out on...
K-Ar geochronology of the Survey Pass, Ambler River and Eastern Baird Mountains quadrangles, southwestern Brooks Range, Alaska
Donald L. Turner, R. B. Forbes, C.F. Mayfield
1978, Open-File Report 78-254
We report 76 previously unpublished K-Ar mineral ages from 47 metamorphic and igneous rocks in the southwestern Brooks Range. The pattern of radiometric ages is complex, reflecting the complex geologic history of this area. Local and regional radiometric evidence suggests that the southern Brooks Range schist belt has, at least...
