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,...
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...
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...
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...
Lake Superior seismic experiment
W. H. Jackson, B. L. Tibbetts
1964, Open-File Report 64-89
During the Lake Superior seismic experiment, an International Upper Mantle cooperative program in July 1965, the U. S. Geological Survey provided a total of 8 mobile seismic-recording systems. For the first phase of the experiment the systems were arranged in two groups of 4; one group at the western end...
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...
Geology and mineral deposits of the Osgood Mountains quadrangle, Humboldt County, Nevada
Preston Enslow Hotz, Charles Ronald Willden
1964, Professional Paper 431
The Osgood Mountains quadrangle is in north-central Nevada northeast of Winnemucca, the principal town in the region. The quadrangle includes two north-northeast-trending mountain ranges, the Osgood Mountains on the east and the Hot Springs Range on the west, which are separated by a narrow valley and are bounded on the east...
Preliminary report on tests of the application of geophysical methods to Arctic ground water problems
David F. Barnes, Gerald R. MacCarthy
1964, Open-File Report 64-9
Seismic refraction and electrical resistivity surveys were made during the summer and fall of 1952 in the Tanana Valley near Fairbanks, Alaska, as part of the studies of the application of geophysical techniques to ground-water problems in Alaska instigated in 1951 by the U.S. Army Engineer Research and Development Laboratories....
