Geochemical explorations for gold deposits at Goldfield, Nevada
Roger P. Ashley, William J. Keith
1978, Open-File Report 78-228
The main problem in geochemical exploration for gold ore bodies in the 40 km2 hydrothermally altered area at Goldfield is to decide which of the many silicified ledges exposed are most likely to yield deposits with additional subsurface exploration. We conclude that the most efficient way to search for exploration...

Development of a relation for steady-state pumping rate for Eagle Valley ground-water basin, Nevada
Freddy E. Arteaga, Timothy J. Durbin
1978, Open-File Report 79-261
Eagle Valley is a topographic and ground-water basin in the west-central area of Nevada. The demand for water in the valley is approaching the limits of the locally available resource, which is the water yield of 9,000 acre-feet per year from the adjacent mountain areas.The steady-state pumping rate from the...

Appraisal of water resources in the Fort McDermitt Indian Reservation, Humboldt County, Nevada
Freddy E. Arteaga
1978, Open-File Report 78-139
Consideration of land-management alternatives in parts of the Fort McDermitt Indian Reservation has prompted an evaluation of water resources in the reservation and vicinity.

Historic ground failures in Northern California triggered by earthquakes
T. Leslie Youd, Seena N. Hoose
1978, Professional Paper 993
A major source of earthquake-related damage and casualties in northern California has been ground failures generated by the seismic shaking, including landslides, lateral spreads, ground settlement, and surface cracks. The historical record shows that, except for offshore shocks, the geographic area affected and the quantity and general severity of ground...
Water budget and water-surface fluctuations, Great Salt Lake, Utah
Ted Arnow
1978, Open-File Report 78-912
The water-budget equation for Great Salt Lakes is: Inflow = Outflow + or - Storage change. The average annual inflow for the period 1931-76 was about 2.9 million acre-feet; 1.9 million acre-feet from surface sources, about 900,000 acre-feet from direct precipitation, and about 75,000 acre-feet from ground water. The average...
Summary of the geology and resources of uranium in the San Juan Basin and adjacent region, New Mexico, Arizona, Utah, and Colorado

1978, Open-File Report 78-964
The San Juan Basin and adjacent region lie predominantly in the southeastern part of the uranium-rich Colorado Plateau of New Mexico, Arizona, Utah, and Colorado. Underlying the province are rocks of the Precambrian basement complex composed mainly of igneous and metamorphic rocks; a thickness of about 3,600 meters of generally...
Estimation of ground motion parameters
David M. Boore, Adolph A. Oliver III, Robert A. Page, William B. Joyner
1978, Open-File Report 78-509
Strong motion data from western North America for earthquakes of magnitude greater than 5 are examined to provide the basis for estimating peak acceleration, velocity, displacement, and duration as a function of distance for three magnitude classes. Data from the San Fernando earthquake are examined to assess the effects of...
Hydrogeology of the karst of Puerto Rico
Ennio V. Giusti
1978, Professional Paper 1012
About one-fifth of Puerto Rico is covered by a tropical karst formed on a series of six limestone formations ranging in age from middle-Oligocene to middle Miocene. These formations strike east to west and crop out over the north coast of the island. Structurally, the rocks form a simple wedge...
Electron-microprobe study of chromitites associated with alpine ultramafic complexes and some genetic implications
M. L. Bird
1978, Open-File Report 78-119
Electron-microprobe and petrographic studies of alpine chromite deposits from around the world demonstrate that they are bimodal with respect to the chromic oxide content of their chromite. The two modes occur at 54 ? 4 and 37 ? 3 weight per cent chromic oxide corresponding to chromite designated as high-chromium...
