Chemical analyses of coal and coal-associated rock samples from the Rosebud and McKay coal beds, Tongue River Member of the Fort Union Formation, Colstrip coal deposit, Rosebud County, Montana
Ronald H. Affolter, Joseph R. Hatch
1979, Open-File Report 79-1098
As part of a continuing program by the U.S. Geological Survey to collect and chemically analyze representative samples of U.S. coals, 61 coal and coal-associated rock samples were collected from the Rosebud and McKay beds in the Paleocene Tongue River Member of the Fort Union Formation in Rosebud County, Montana....
Forensic seismology
H. I. S. Thirlaway
1979, Earthquake Information Bulletin (USGS) (11) 156-164
Twenty years ago, politicians, concerned a the slow progress of negotiations to stop nuclear weapons testing, described the state of seismology as being in the equivalent of the Stone Age. this assessment spurred the beginning of research and development at the Atomic Weapons Research Establishment near the village of Aldermaston,...
Geohydrology of Brooks, Lowndes, and western Echols Counties, Georgia
R.E. Krause
1979, Water-Resources Investigations Report 78-117
The principal artesian aquifer, a limestone of Eocene to Miocene age, is the main source of water supply for Brooks, Lowndes, and western Echols Counties in south Georgia. Pumpage of about 22 million gallons perday from this prolific aquifer has not posed any problems regarding declining water levels or depletion...
Modeling of rock friction 1. Experimental results and constitutive equations
James H. Dieterich
1979, Conference Paper, Journal of Geophysical Research B: Solid Earth
Direct shear experiments on ground surfaces of a granodiorite from Raymond, California, at normal stresses of ??6 MPa demonstrate that competing time, displacement, and velocity effects control rock friction. It is proposed that the strength of the population of points of contacts between sliding surfaces determines frictional strength and that...
Ethyl-p-aminobenzoate (Benzocaine): efficacy as an anesthetic for five species of freshwater fish
V. K. Dawson, P.A. Gilderhus
1979, Investigations in Fish Control 87
Ethyl-p-aminobenzoate (benzocaine) was tested for its efficacy as an anesthetic for rainbow trout (Salmo gairdnerii, brown trout (Salmo truttas, northern pike (Esox lucius). carp (Cyprinus carpio), and largemouth bass (Mieropterus salmoidesi. Since benzocaine is not water soluble, it was applied with acetone as a carrier. Concentrations of 100 to 200...
The Survey’s first venture into seismology
M. C. Rabbitt
1979, Earthquake Information Bulletin (USGS) (11) 50-52
The occurrence of two small but widely felt earthquakes in the Eastern United States in 1884 led an editor of the research journal Science to suggest, in the October 3 issue of the magazine, that an "earthquake club" be formed. Its purpose was so that observers and students of "this branch...
A herringbone bedform pattern of possible Taylor-Görtler type flow origin seen in sonographs
Lawrence J. Toimil, Erk Reimnitz
1979, Sedimentary Geology (22) 219-228
Side-scan sonar records collected in a shallow arctic lagoon (2–2.5 m depth) reveal a herringbone pattern of current-aligned linear reflectors with branching diagonals. The major longitudinal reflectors have no detectable relief (<20 cm), are spaced 5–10 m apart, and may represent current-aligned helical cell boundaries preserved in the silty fine...
Geologic implications and potential hazards of scour depressions on bering shelf, Alaska
M. C. Larsen, H. Nelson, D.R. Thor
1979, Environmental Geology (3) 39-47
Flat-bottomed depression 50-150 m in diameter and 60-80 cm deep occur in the floor of Norton Sound, Bering Sea. These large erosional bedforms and associated current ripples are found in areas where sediment grain size is 0.063-0.044 mm (4-4.5 ??), speeds of bottom currents are greatest (20-30 cm/s mean speeds...
Volcanic features of Io
M. H. Carr, H. Masursky, R.G. Strom, R.J. Terrile
1979, Nature (280) 729-733
Volcanic activity is apparently higher on Io than on any other body in the Solar System. Its volcanic landforms can be compared with features on Earth to indicate the type of volcanism present on Io. ?? 1979 Nature Publishing Group....
Geochemical and hydrologic considerations and the use of enthalpy-chloride diagrams in the prediction of underground conditions in hot-spring systems
R.O. Fournier
1979, Journal of Volcanology and Geothermal Research (5) 1-16
Thermal water ascending in a hot-spring system may cool by conduction of heat to the surrounding rock, by boiling, by mixing with cooler water, or by a combination of these processes. Complete or partial chemical reequilibration may occur as a result of this cooling. In spite of these complexities, in...
Probability weighted moments compared with some traditional techniques in estimating Gumbel Parameters and quantiles
J. Maciunas Landwehr, N.C. Matalas, J.R. Wallis
1979, Water Resources Research (15) 1055-1064
Estimates of the parameters and quantiles of the Gumbel distribution by the methods of probability weighted moments, (conventional) moments, and maximum likelihood were compared. Results were derived from Monte Carlo experiments by using both independent and serially correlated Gumbel numbers. The method of probability weighted moments was seen...
A review of recent activity in the United States.
H.L. Cannon, W.L. Petrie
1979, Philosophical Transactions of the Royal Society B: Biological Sciences (288) 137-149
Either an overabundance or a deficiency of trace metals in the food chain can ultimately affect adversely the health of livestock and man. Increasing interest in the United States in the distribution of metals in the environment and in metal pollutants has led to widespread interdisciplinary research sponsored by governmental,...
