Strain accumulation along the San Andreas fault system east of San Francisco Bay, California
W.H. Prescott, M. Lisowski
1983, Tectonophysics (97) 41-56
The occurrence of several large earthquakes to the east of San Francisco Bay during historical times, and present high levels of microseismicity, indicate that a significant part of the relative plate motion may be occurring east of San Francisco Bay. Furthermore, the Hayward fault is known to be slipping aseismically...
Alteration and vein mineralization, Schwartzwalder uranium deposit, Front Range, Colorado
Alan R. Wallace
1983, Open-File Report 83-417
The Schwartzwalder uranium deposit, in the Front Range west of Denver, Colorado, is the largest vein-type uranium deposit in the United States. The deposit is situated in a steeply dipping fault system that cuts Proterozoic metamorphic rocks. The host rocks represent a submarine volcanic system with associated chert and iron-...

1983, Open-File Report 83-816
The Emma Bell chromite deposit in Siskiyou County, California contains over 5 million tons of dunite averaging about 4 percent Cr2O3. Chromite is not evenly disseminated throughout the dunite, however. For the most part the deposit consists of many chromite-rich bands in sharp contact with, and separated by, common dunite...

Electromagnetic induction data using distant field sources, mostly of natural origin, in the frequency range of 4.5-27,000 Hz are analyzed to depict the geoelectric structure in an area of volcanic-rock cover located in southeastern Arizona between the Morenci and Safford porphyry copper deposits. The data for each station consist of...

K.J. Hollett
1983, Open-File Report 83-774
The Papago Farms-Great Plain and upper Rio Sonoyta study area includes about 490 square miles in south-central Arizona and north-central Sonora, Mexico. In the study area 23,700 acre-feet of ground water from the basin-fill deposits was used to irrigate more than 5,000 acres in 1981. Surface water is not a...
Application of remote-sensing techniques to hydrologic studies in selected coal-mined areas of southeastern Kansas
J. F. Kenny, J. R. McCauley
1983, Water-Resources Investigations Report 83-4007
Disturbances resulting from intensive coal mining in the Cherry Creek basin of southeastern Kansas were investigated using color and color-infrared aerial photography in conjunction with water-quality data from simultaneously acquired samples. Imagery was used to identify the type and extent of vegetative cover on strip-mined lands and the extent and...

Connector well experiment to recharge the Floridan aquifer, east Orange County, Florida
Peter W. Bush
1983, Water Supply Paper 2210
An experimental connector well, screened in the shallow sand aquifer, finished with open hole in the Floridan aquifer and cased through the confining layer between the two aquifers, was drilled in east Orange County, Fla., to obtain information on the nature and function of the shallow aquifer as related to...

Annual water-resources review, White Sands Missile Range, New Mexico, 1982
R. R. Cruz
1983, Open-File Report 83-695
Ground-water data were collected in 1982 at White Sands Missile Range in south-central New Mexico. Depth-to-water measurements in the Post Headquarters supply wells continued to show seasonal declines. Test wells east of the Headquarters well field continue to show long-term declines as well as seasonal fluctuations. The total amount of...
Surface water and climatologic data, Salt Lake County, Utah, water year 1981, with selected data for water years 1980 and 1982

Daily water and sediment discharges from selected rivers of the eastern United States; a time-series modeling approach
Michael G. Fitzgerald, Michael R. Karlinger
1983, Water Supply Paper 2216
Time-series models were constructed for analysis of daily runoff and sediment discharge data from selected rivers of the Eastern United States. Logarithmic transformation and first-order differencing of the data sets were necessary to produce second-order, stationary time series and remove seasonal trends. Cyclic models accounted for less than 42 percent...
Numerical simulation of ground-water flow in lower Satus Creek Basin, Yakima Indian Reservation, Washington
E. A. Prych
1983, Water-Resources Investigations Report 82-4065
A multilayer numerical model of steady-state ground-water flow in lower Satus Creek basin was constructed, calibrated using time-averaged data, and used to estimate the long-term effects of proposed irrigation-water management plans on ground-water levels in the area. Model computations showed that irrigation of new lands in the Satus uplands would...
