A total intensity magnetic anomaly map of the Red Sea and its interpretation
Stuart A. Hall
1979, Open-File Report 80-131
All available total intensity magnetic field data have been used to prepare a total intensity magnetic anomaly map of the Red Sea at a scale of 1:2,000,000. These include airborne surveys at various elevations and numerous sea surveys. The data have been digitised at approximately one kilometre intervals and the...
The use of Vacutainer tubes for collection of soil samples for helium analysis
Margaret Hinkle, James E. Kilburn
1979, Open-File Report 79-1441
Measurements of the helium concentration of soil samples collected and stored in Vacutainer-brand evacuated glass tubes show that Vacutainers are reliable containers for soil collection. Within the limits of reproducibility, helium content of soils appears to be independent of variations in soil temperature, barometric pressure, and quantity of soil moisture...
Southeast Georgia embayment high-resolution seismic-reflection survey
Douglas W. Edsall
1979, Open-File Report 78-800
A high-resolution seismic survey of the offshore part of the Southeast Georgia Embayment on about a 20 km spacing was completed in 1976. A stratigraphic analyses of the data shows that the largest controlling factor in the depositional history of the shelf has been the Gulf Stream. These currents have...
Analysis of ground water by different laboratories: a comparison of chloride and nitrate data, Nassau and Suffolk counties, New York
Brian G. Katz, Richard K. Krulikas
1979, Open-File Report 79-1063
Water samples from wells in Nassau and Suffolk Counties were analyzed for chloride and nitrate. Two samples were collected at each well; one was analyzed by the U.S. Geological Survey, the other by a laboratory in the county from which the sample was taken. Results were compared statistically by paired-sample...
The concentration and mobility of elements in subalpine forest soils in Colorado and Idaho
Gary C. Curtin, Harley D. King, J. M. Nishi
1979, Open-File Report 79-710
Leaching studies of subalpine forest soils collected at seven sites in Colorado and Idaho show that copper, cobalt, chromium, magnesium, barium, tin, strontium, and yttrium are highly mobile elements in these soils; that zirconium, lanthanum, nickel, and scandium are moderately mobile; and that titanium is rather immobile. Furthermore, the results...
Preliminary report on Tertiary volcanism and uranium mineralization in the Thomas Range and northern Drum Mountains, Juab County, Utah
David Allen Lindsey
1979, Open-File Report 79-1076
The Thomas Range and northern Drum Mountains have a history of volcanism, faulting, and mineralization that began about 42 m.y. ago. Volcanic activity and mineralization in the area can be divided into three stages according to the time-related occurrence of rock types, trace element associations, and chemical nature of mineralization....
Particle size of sediments collected from the bed of the Amazon River and its tributaries in May and June 1977
Carl F. Nordin, R.H. Meade, W. F. Curtis, N.J. Bosio, B. M. Delaney
1979, Open-File Report 79-329
One-hundred-eight samples of bed material were collected from the Amazon River and its major tributaries between Belem, Brazil , and Iquitos, Peru. Samples were taken with a standard BM-54 sampler or with pipe dredges from May 18 to June 5, 1977. Most of the samples have median diameters in the...
