Geology of the Carlin gold deposit, Nevada
Arthur S. Radtke
1981, Open-File Report 81-97
The Carlin gold deposit, near the crest of the Tuscarora Range in the Lynn mining district, about 35 km north of Carlin, Nev., is the largest hydrothermal disseminated-replacement deposit discovered to date in North America. The mine began production in 1965 and between 1965 and 1976 produced about 2 million...
Effects of Mount St. Helens eruption on selected lakes in Washington
N. P. Dion, S.S. Embrey
1981, Circular 850-G
During several periods of volcanic-ash eruption at Mount St. Helens, Wash., (March 30, May 25-26, May 30-June 2, and June 12-13, 1980) strong winds from the north occurred at high altitudes. As a result, the volcanic ash fell some 50 miles to the south in the Bull Run watershed, the...
An oilspill risk analysis for the Beaufort Sea, Alaska (proposed sale 71)outer continental shelf lease area
W.B. Samuels, Dorothy Hopkins, K.J. Lanfear
1981, Open-File Report 82-13
An oilspill risk analysis was conducted to determine the relative environmental hazards of developing oil in different regions of the Beaufort Sea, Alaska, (Proposed Sale 71) Outer Continental Shelf (OCS) lease area. The probability of spill occurrences, likely movement of oil slicks, and locations of resources vulnerable to spilled oil...
Water use in Ohio, 1975
R. Michael Hathaway, Michael Eberle
1981, Water-Resources Investigations Report 81-17
The estimated water use in Ohio for all purposes in 1975 was 16 ,431 million gallons per day. Of this total, 15,321 were taken from surface water while the remaining 1,110 represent ground-water withdrawals. Totals by category are as follows (in million gallons per day): Thermoelectric power generation, 12 ,404;...
Hydrologic reconnaissance of the Wasatch Plateau-Book Cliffs coal-fields area, Utah
Kidd M. Waddell, P. Kay Contratto, C. T. Sumsion, John R. Butler
1981, Water Supply Paper 2068
Data obtained during a hydrologic reconnaissance in 1975-77 in the Wasatch Plateau-Book Cliffs coal-fields area of Utah were correlated with existing long-term data. Maps were prepared showing average precipitation, average streamflow, stream temperature, ground- and surface-water quality, sediment yield, and geology. Recommendations were made for additional study and suggested approaches...
Multi-saline sample distillation apparatus for hydrogen isotope analyses: Design and accuracy
Afifa Afifi Hassan
1981, Water-Resources Investigations Report 81-25
A distillation apparatus for saline water samples was designed and tested. Six samples may be distilled simultaneously. The temperature was maintained at 400 C to ensure complete dehydration of the precipitating salts. Consequently, the error in the measured ratio of stable hydrogen isotopes resulting from incomplete dehydration of hydrated salts...

Robert F. Gilmore, Linda-Lee Harris, Lisa D. Tennison
Katherine M. Reed, editor(s)
1981, Circular 843
This Circular describes the 1981 programs and projects of the U.S. Geological Survey in Alaska. A brief description of the Alaskan operations of each office and division of the Survey is followed by project descriptions arranged by geographic regions in which the work takes place. The largest program at present...
