Geographic centers of the United States
Water Resources Division, U.S. Geological Survey
1964, Report
There is no generally accepted definition of geographic center, and no completely satisfactory method for determining it. Because of this, there may be as many geographic centers of a State or country as there are definitions of the term. The geographic center of an area may be defined as the...

Specific yield - laboratory experiments showing the effect of time on column drainage
R.C. Prill, A.I. Johnson, D. A. Morris
1964, Report
The increasing use of ground water from many major aquifers in the United States has required a more thorough understanding of gravity drainage, or specific yield. This report describes one phase of specific yield research by the U.S. Geological Survey's Hydrologic Laboratory in cooperation with the California Department of Water...
Water quality of the Swatara Creek Basin, PA
Edward F. McCarren, J.W. Wark, J.R. George
1964, Report
The Swatara Creek of the Susquehanna River Basin is the farthest downstream sub-basin that drains acid water (pH of 4.5 or less) from anthracite coal mines. The Swatara Creek drainage area includes 567 square miles of parts of Schuylkill, Berks, Lebanon, and Dauphin Counties in Pennsylvania.To learn what environmental factors...

Distribution of mercury, silver, tellurium, arsenic, and antimony in the Rowe Canyon area, White Pine County, Nevada
Garland Bayard Gott, Joseph Howard McCarthy Jr.
1964, Open-File Report 64-63
The accompanying geochemical maps are based in part on data published in U.S. Geological Survey Professional Paper 450-E, Article 180 (Brokaw and others, 1963), and in part on new data acquired since the publication of Professional Paper 450-E. The mercury was determined by atomic absorption techniques, as described by Vaughn...

The geology, mineralogy and paragenesis of the Castrovirreyna lead-zinc-silver deposits, Peru
Richard Wheatley Lewis Jr.
1964, Open-File Report 64-103
The Castrovirreyna mining district lies in the Andean Cordillera of South Central Peru, and has been worked sporadically since its discovery in 1591. Supergene silver ores were first mined. Currently the district produces about 20,000 tons of lead-zinc ore and 5000 tons of silver ore annually. The district is underlain by...
Geology applied to study of coal mine bumps and mining methods at Sunnyside, Utah
Frank W. Osterwald, C. Richard Dunrud
1964, Open-File Report 64-122
Coal mine bumps are a serious hazard to life and property in the mines of east-central Utah. Research into geologic factors associated with these bumps indicates that the bumps are spatially and genetically related to structural and stratigraphic features. Some bumps are directly related to stress accumulation along faults, either...
Review of waterpower withdrawals in Weiser River Basin, Idaho
Jesse Lane Colbert, Loyd L. Young
1964, Open-File Report 64-39
The Weiser River basin is primarily agricultural and is supported by extensive irrigation. The Geological Survey has initiated withdrawals, or has made powersite classifications of lands having value for reservoir sites and for waterpower production. These withdrawals have been examined to see if they should continue in force or if...

Subsurface geology of the upper Cretaceous Kirtland and Fruitland formations of the San Juan Basin, New Mexico and Colorado
James E. Fassett
1964, Open-File Report 64-53
The San Juan Basin is an asymmetrical structural basin in northwestern New Mexico and southwestern Colorado. The basin contains sedimentary rocks ranging from Cambrian through Recent in age and attaining a maximum thickness between 14,000 and 15,000 feet. The Upper Cretaceous sedimentary rocks exceed 8,000 feet in thickness and can...

Copper determinations on samples of alluvium and caliche from the rocky Range, Beaver County, Utah
Ralph Leroy Erickson, Albert Pasquale Marranzino
1964, Open-File Report 64-49
A study of the distribution of copper in transported alluvium on a pediment of the Rocky Range, Beaver County, Utah, undertaken to determine whether known copper deposits in bedrock concealed by alluvium could be detected by geochemical methods, was reported in Geological Survey Research 1960 ( Erickson, R.L., and Marrenzino,...
