Integrated uranium system in the Marysvale volcanic field, west-central Utah
T. A. Steven, C. G. Cunningham, M. N. Machette
1981, Book chapter, Uranium in volcanic and volcaniclastic rocks
Uranium in the Marysvale volcanic field is known to occur in several geologic environments and is thought to occur in others. These known and hypothetical occurrences are of various kinds, ranging in derivation from rhyolite magma, through porphyry-type deposits, hydrothermal vein deposits, dispersed hydrothermal deposits, and, after secondary transport in...
Peak horizontal acceleration and velocity from strong-motion records including records from the 1979 imperial valley, California, earthquake
William B. Joyner, David M. Boore
1981, Bulletin of the Seismological Society of America (71) 2011-2038
We have taken advantage of the recent increase in strong-motion data at close distances to derive new attenuation relations for peak horizontal acceleration and velocity. This new analysis uses a magnitude-independent shape, based on geometrical spreading and anelastic attenuation, for the attenuation curve. An innovation in technique is introduced that...

1981, Madroño (28) 255-272
A 2.1-m core from Laguna de las Trancas, a marsh atop a landslide in northern Santa Cruz County, California, has yielded a pollen record for the period between about 30,000 B. P. and roughly 5000 B. P. Three pollen zones are recognized. The earliest is characterized by high frequencies of...

Water resources of the Kisatchie well-field area near Alexandria, Louisiana
James E. Rogers
1981, Water Resources Technical Report 26
Sands of Miocene, Pliocene(?), and Pleistocene age contain fresh-water in central Rapides Parish, La. In this area the base of fresh ground water ranges from 900 feet to more than 2,500 feet below National Geodetic Vertical Datum of 1929. The principal sources of water are the Carnahan Bayou, Williamson Creek,...

Geohydrology of the Antlers aquifer (Cretaceous), southeastern Oklahoma
Donald L. Hart Jr., Robert E. Davis
1981, Circular 81
The Antlers aquifer, which consists of as much as 900 feet of friable sandstone, silt, clay, and shale, crops out in an area of 1,860 square miles and underlies about 4,400 square miles in southeastern Oklahoma. Precipitation ranges from 35 to 50 inches per year across the outcrop area, which...

The possible role of sulfate-reduction kinetics in the formation of hydrothermal uranium deposits
Charles S. Spirakis
1981, Economic Geology (76) 2236-2239
Sulfate is known to be an active oxidizing agent at high temperatures; however, both experimental and geologic evidence indicate that as a hydrothermal solution cools (to about 200 degrees C, depending on pH) kinetic factors slow the rate at which sulfate enters into redox reactions. This retardation of sulfate reduction...
Water resources of the Rincon and Mesilla Valleys and adjacent areas, New Mexico
Clyde A. Wilson, Robert R. White, Brennon R. Orr, R. Gary Roybal
1981, Technical Report 43
The Rincon and Mesilla Valleys of New Mexico extend from Caballo Reservoir to El Paso del Norte, west of El Paso, Texas. Water supplies for this area are obtained from the Rio Grande and from the saturated sediments filling the intermontane basins of south-central New Mexico.The two major aquifers are...

Ground-water conditions in the upper Virgin River and Kanab Creek basins area, Utah, with emphasis on the Navajo sandstone
R.M. Cordova
1981, Technical Publication 70
The upper Virgin River and Kanab Creek basins area occupies parts of Iron, Kane, and Washington Counties in south-central Utah. It includes about 1,300 square miles (3,370 square kilometers) in the upper Virgin River basin and about 650 square miles (1,680 square kilometers) in the upper Kanab Creek basin. The...
