Publication Extents

Not all publications have extents, not all extents are completely accurate
A general purpose contouring system
Gerald Ian Evenden
1975, Open-File Report 75-317
Three Decsystem-10 FORTRAN IV programs provide a general purpose system for contouring two-dimensional data. The system can provide both quick or final, publication quality contour maps on either interactive or offline plotting devices. Complete user documentation, with examples, and program listings are presented....
Analytical data for geologic units in Missouri and parts of Kansas, Oklahoma and Arkansas
Josephine G. Boerngen, George Van Trump, Richard J. Ebens
1975, Open-File Report 75-137
This report lists the geochemical data collected during the course of a reconnaissance study of compositional variation in the bedrock and surficial gelogic untis exposed in Missouri and adjoining parts of Kansas, Oklahoma, and Arkansas.  The primar object of the study was to assess scale-related components of geochemical variance with...
A review of recently active faults in Taiwan
Manuel G. Bonilla
1975, Open-File Report 75-41
Six faults associated with five large earthquakes produced surface displacements ranging from 1 to 3 m in the period 1906 through 1951. Four of the ruptures occurred in the western coastal plain and foothills, and two occurred in the Longitudinal Valley of eastern Taiwan. Maps are included showing the locations...
Erosion and sediment transport in the Owens River near Bishop, California
Rhea P. Williams
1975, Water-Resources Investigations Report 75-49
Closure of Pleasant Valley Dam in 1954 has almost eliminated the supply of gravel to the 16-mile (25.7-kilometre) study reach of the Owens River. Because of armoring of the channel, scour has been limited to approximately 1 foot (0.3 metre) in the upper 2.3 miles (3.7 kilometres).This report presents information...
Preliminary hydrogeologic appraisal of selected hydrothermal systems in northern and central Nevada
F. H. Olmsted, P.A. Glancy, J. R. Harrill, F. E. Rush, A. S. Van Denburgh
1975, Open-File Report 75-56
Several hydrothermal systems in northern and central Nevada were explored in a hydrogeologic reconnaissance. The systems studied comprise those at Stillwater and Soda Lakes-Upsal Hogback in the Carson Desert, Gerlach, Fly Ranch-Granite Range, and Double Hot Springs in the Black Rock Desert, Brady's Hot Springs, Leach Hot Springs in Grass...
Studies for seismic zonation of the San Francisco Bay region
Roger D. Borcherdt
1975, Professional Paper 941-A
The analyses presented in the preceding six papers show that the geologic setting of the San Francisco Bay region has a dominant influence on potential earthquake hazards. The strong correlation between geologic conditions and the amount of earthquake damage in 1906 emphasizes the importance of this influence and demonstrates the...
Geologic framework of the Alaskan Continental Terrace in the Chukchi and Beaufort seas
Arthur Grantz, Mark L. Holmes, B. A. Kososki
1975, Open-File Report 75-124
Seismic, magnetic and gravity data indicate that the Chukchi and Beaufort epicontinental seas off northern Alaska overlie three sedimentary basins, or provinces, separated by structural highs of regional extent. The basins trend west to northwest and become increasingly marine from south to north. The Chukchi-Beaufort continental margin is similar to...
Water resources data for Hawaii and other Pacific areas, water year 1974
Water Resources Division, U.S. Geological Survey
1975, Water Data Report HI-74-1
Water resources data for the 1974 water year for Hawaii and other Pacific areas including records of streamflow or reservoir storage at gaging stations, partial-record stations, and miscellaneous sites, and records of water-quality data on the chemical and physical characteristics of surface water, are given in this report. The records...
Satellite relay and processing of hydrologic data in south Florida
E.T. Wimberly
1975, Water-Resources Investigations Report 75-12
Management of water in south Florida requires current hydrologic data on water levels and rainfall. This need is being met by a data processing system which provides near-real-time data from remote areas. The flow of data is from data-collection platforms at field sites via LANDSAT-1 satellite to the National Aeronautics...
Summary of references to mineral occurrences (other than mineral fuels and construction materials) in the Teller Quadrangle, Alaska
Edward Huntington Cobb
1975, Open-File Report 75-587
This summary of references is designed to aid in library research on metallic and nonmetallic (other than mineral fuels and construction materials) mineral occurrences in the Teller quadrangle, Alaska. All references to published and open-filed reports of the Geological Survey, to most published and open-filed reports of the U.S. Bureau...
Environmental tritium in the Edwards Aquifer, central Texas 1963-71
Frederick Joseph Pearson, Paul L. Rettman, T.A. Wyerman
1975, Open-File Report 74-362
Tritium concentrations of samples from 50 wells and springs in the Edwards aquifer in the San Antonio area of Texas have been analysed. Tritium now in the aquifer is partly natural cosmic ray produced tritium, but most is tritium produced by atmospheric thermonuclear tests in the 1950's and early 1960's....
Water temperature-influential factors, field measurement, and data presentation
Herbert H. Stevens, John F. Ficke, George F. Smoot
1975, Techniques of Water-Resources Investigations 01-D1
This manual contains suggested procedures for collecting and reporting of water-temperature data on streams, lakes and reservoirs, estuaries, and ground water. Among the topics discussed are the selection of equipment and measuring sites, objectives and accuracy of measurements, and data processing and presentation. Background information on the influence...
Ground-water availability in the Belcourt area, Rolette County, North Dakota
P.G. Randich
1975, Open-File Report 75-104
Test drilling and geologic data indicate that there are two potential aquifers in the Belcourt, N. Dak. area capable of supplying a sufficient quantity of ground water for the city of Belcourt.  The Fox Hills aquifer, located about 3 miles (4.8 kilometres) west of Belcourt, could yield a sufficient quantity,...
