Performance assessments for radioactive waste repositories; the rate of movement of faults
Newell J. Trask
1982, Open-File Report 82-972
Performance assessments of mined repositories for radioactive waste require estimates of the likelihood of fault movements and earthquakes that may affect the repository and its surrounding ground water flow system. Some previous assessments have attempted to estimate the rate of formation of new faults; some have relied heavily on historic...
Determination of the true density of pulverized coal samples
R.W. Stanton
1982, Open-File Report 82-835
A method using the gas-comparison pycnometer with helium gas as the penetrating medium measures precisely the true volume of a pulverized coal sample. The true density of a solid is calculated as the true unit volume of the solid exclusive of its pore space which is divided into the weight...
Diatremes of the Hopi Buttes, Arizona; chemical and statistical analyses
K. J. Wenrich, J. F. Mascarenas
1982, Open-File Report 82-740
Lacustrine sediments deposited in maar lakes of the Hopi Buttes diatremes are hosts for uranium mineralization of as much as 1500 ppm. The monchiquites and limburgite turfs erupted from the diatremes are distinguished from normal alkalic basalts of the Colorado Plateau by their extreme silica undersaturation and high water, TiO2,...
Ground-water data for Georgia, 1981
S.E. Matthews, Willis G. Hester, K.W. McFadden
1982, Open-File Report 82-904
More than 2,000 water-level measurements made in Georgia in 1981 provide the basic data for this report. Daily mean water-level fluctuations and trends are shown in hydrographs for the previous year (1980) and fluctuations of the monthly mean water levels are shown for selected years in some observation wells in...
Annotated report and data inventory for the Mississippi and Minnesota rivers, Minneapolis-St. Paul metropolitan area
T. A. Winterstein
1982, Open-File Report 82-869
This inventory of reports and data concerning the Mississippi and Minnesota Rivers in the Twin Cities metropolitan area was compiled from November 1981 through January 1982 for a planned river-quality assessment to be conducted cooperatively by the U.S. Geological Survey and the Metropolitan Waste Control Commission. There are 260 annotated...
Heat-flow measurements at shot points along the 1978 Saudi Arabia seismic deep-refraction line; Part I, Results of the measurements
M. E. Gettings, Abdullah Showail
1982, Open-File Report 82-793
Heat-flow measurements were made at five onland shot points of the 1978 Saudi Arabian seismic deep-refraction line, which sample major tectonic elements of the Arabian Shield along a profile from Ar Riyad to the Farasan Islands. Because of the pattern drilling at each shot point, several holes (60 m deep)...
Position of the saltwater-freshwater interface in the upper part of the Floridan Aquifer, southwest Florida, 1979
K.W. Causseaux, J. D. Fretwell
1982, Open-File Report 82-90
Ground-water withdrawals in southwest Florida are increasing because of urban growth, industrial expansion and increased agricultural irrigation. As a result, the potentiometric surface of the Floridian aquifer has been lowered in some areas, allowing seawater to encroach into the aquifer and threaten the freshwater resources of the area. Effective management...
