Geology, of the High Climb Pegmatite, Custer County, South Dakota
Douglas M. Sheridan
1953, Trace Elements Investigations 231
The High Climb pegmatite, Custer County, S. Dak., belongs to the series of pegmatitic and granitic rocks that characterize the Harney Peak region of the southern Black Hills. It intrudes pre-Cambrian metamorphic rocks consisting chiefly of quartz-mica schist. The country rock has been altered to a tourmaline-rich schist along part...
Occurrences of uranium-bearing minerals in the St. Kevin District, Lake County, Colorado
C. T. Pierson, Q. D. Singewald
1953, Trace Elements Investigations 234
Two hundred and seventy-one prospect pits, mine dumps, or mine workings within the Sugar Loaf-St. Kevin mining districts and vicinity were tested for radioactivity by the U.S. Geological Survey in 1951 during six weeks of investigation on behalf of the Division of Raw Materials of the U.S. Atomic Energy Commission....
Chemical and physical quality examination
William Lamar
1953, Book chapter, Lake Erie pollution survey. Final report.
In a balanced study of water pollution or water utilization a thorough chemical and physical examination is essential. This provides a basis for evaluation of stream conditions, their effects and remedies. Such information is of value to the general public who are interested in clean water and in recreation, hunting,...
Hydrology of Lake Erie and tributaries
L. C. Crawford
1953, Book chapter, Lake Erie pollution survey. Final report
The drainage area of the Great Lakes is equal to nearly one-tenth of the entire area of the United States; 58 percent of this area lies within the United States. The information in Table 3 affords a ready comparison of the land and water areas involved in the United States...
The measurement of total sediment load in alluvial streams
P.C. Benedict, D.Q. Matejka
John S. McNown, M.C. Boyer, editor(s)
1953, Conference Paper, Proceedings of the fifth Hydraulics Conference, June 9-11, 1952, arranged by the Iowa Institute of Hydraulic Research
The measurement of the total sediment load transported by streams that flow in alluvial channels has been a perplexing problem to engineers and geologists for over a century. Until the last decade the development of equipment to measure bed load and suspended load was carried on almost independently, and without...
Ground-water problems in highway construction and maintenance
W. C. Rasmussen, L. B. Haigler
1953, Bulletin 1
This report discusses the occurrence of ground water in relation to certain problems in highway construction and maintenance. These problems are: the subdrainage of roads; quicksand; the arrest of soil creep in road cuts; the construction of lower and larger culverts necessitated by the farm-drainage program; the prevention of failure...
Preliminary report on the Clancy Creek area, Jefferson City quadrangle, Jefferson County, Montana
George E. Becraft
1953, Trace Elements Investigations 257
Several radioactivity anomalies and secondary uranium minerals have been found in the Clancy Creek area near the northern margin of the Boulder batholith. These are principally associated with chalcedonic zones that consist of one or more discontinuous stringers and veins of cryptocrystalline silica and fine-grained quartz in silicified quartz monzonite...
Uranium-bearing coal and carbonaceous shale in La Ventana Mesa area, Sandoval County, New Mexico
James D. Vine, George O. Bachman, Charles B. Read, George W. Moore
1953, Trace Elements Investigations 241
Uranium-bearing coal, carboanceous shale, and carboaceous sandstone of Upper Cretaceous age occur on and adjacent to La Ventana Mesa, Sandoval County, New Mexico.  The geologic features of the uranium deposits are described and a hypothesis for the origin and control of the uranium deposits are described and a hypothesis for...
