Experimental results of atomic absorption analyses for indium and thallium in 803 nonmagnetic concentrates from Alaska
William C. Overstreet, George L. Crenshaw, Arthur E. Hubert, Sam Rosenblum, Ricke J. Smith
1975, Open-File Report 75-253
The development in the U.S. Geological Survey of rapid methods for the determination by atomic absorption spectrophotometry of indium and thallium at limits of detection as low as 0.2 ppm each in geologic materials affords great advantages over spectrographic methods in studies concerned with values at or near the crustal...
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....

Interim report on petroleum resource potential and geologic hazards in the outer continental shelf of the Gulf of Alaska Tertiary province
George Plafker, Terry R. Bruns, Robert A. Page
1975, Open-File Report 75-592
The potential for discovering large accumulations of petroleum on the Outer Continental Shelf of the Gulf of Alaska Tertiary Province cannot be evaluated with much confidence at present because of the inadequacies of the available offshore geological and geophysical data. The 22 deep test wells that have been drilled since...
Petrography of University of Washington dredge samples for the central Chukchi Sea
Jeremy B. Platt
1975, Open-File Report 75-269
Twenty thin sections of rocks dredged from the central Chukchi Sea have been examined petrographically and compared with some onshore rocks in northern Alaska. Of these, 16 are sandstones, three are highly CaCO3-rich silts and carbonate rocks, and one is an olivine-magnetite-rich basalt. Eight of the sandstones have been point-counted...

Preliminary evidence for Holocene movement along the Belair fault zone near Augusta, Georgia
David C. Prowell, Bruce J. O’Connor, Meyer Rubin
1975, Open-File Report 75-680
The Belair fault zone has the youngest displacement recognized to date in the southeastern United States and is the only fault zone dated as having moved in Holocene time. A trench cut across one of the faults in the zone shows lenses of organic material cut by and dragged into...
Numerical model of the salt-wedge reach of the Duwamish River estuary, King County, Washington
Edmund A. Prych, W.L. Haushild, J.D. Stoner
1975, Open-File Report 75-13
A numerical model of a salt-wedge estuary developed by Fischer has been expanded and used to calculate the distributions of salinity, temperature, chlorophyll a concentrations, biochemical oxygen demand, and dissolved-oxygen concentrations in the Duwamish River estuary, King County, Wash. With this model, which was calibrated and verified with observed data,...

1975, Open-File Report 75-396
The city of Belcourt, Agency headquarters for the Turtle Mountain Indian Reservation, is located in northeastern Rolette County, north-central North Dakota. At the request of the U.S. Public Health Service, the U.S. Geological Survey conducted a study in the vicinity of Belcourt to assist in location of a suitable water...
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,...
