Flow resistance in sinuous or irregular channels
Luna Bergere Leopold, Ralph A. Bagnold, M. Gordon Wolman, Lucien M. Brush Jr.
1960, Professional Paper 282-D
The resistance to fully developed turbulent flow at constant depth in an open channel increases as the square of the mean velocity as long as the boundary conditions remain completely unchanged. The presence of the free water surface allows the possibility of departure from the relationship of resistance to the...
Experimental drill hole logging in potash deposits of the Carlsbad district, New Mexico
C.L. Jones, C. Gilbert Bowles, Kenneth Granville Bell
1960, Open-File Report 60-84
Experimental logging of holes drilled through potash deposits in the Carlsbad district, southeastern New Mexico, demonstrate the considerable utility of gamma-ray, neutron, and electrical resistivity logging in the search for and identification of mineable deposits of sylvite and langbeinite. Such deposits are strongly radioactive with both gamma-ray and neutron well...
Origin and chemical composition of evaporite deposits
George William Moore
1960, Open-File Report 60-99
A comparative study of marine evaporite deposits forming at the present time along the pacific coast of central Mexico and evaporite formations of Permian age in West Texas Basin was made in order to determine if the modern sediments provide a basis for understanding environmental conditions that existed during deposition...
Pumice and pozzolan deposits in the Lesser Antilles
Edwin Butt Eckel
1960, Open-File Report 60-48
Early in 1959 the International Cooperation Administration requested the U. S. Geological Survey to assign a geologist to a reconnaissance study of the pumice and pozzolan deposits of the Lesser Antilles. As a result, I made brief field examinations of all the reported deposits during the period May 25 -...
An aeromagnetic reconnaissance of the Cook Inlet area, Alaska
Arthur Grantz, Isidore Zietz, Gordon E. Andreasen
1960, Open-File Report 60-59
Forty-two east-west aeromagnetic lines were flown across the Cook Inlet-Susitna Lowland between Chelatna Lake and Seldovia at a flight altitude of approximately 2,500 feet. The lines traverse all or part of five Mesozoic tectonic elements that dominate the structure of the Cook Inlet area. Each of these tectonic elements, the...
Petrography and petrology of Smoky Butte intrusives, Garfield County, Montana
Robert E. Matson
1960, Open-File Report 60-96
The Smoky Butte intrusives are located in T. 18 N., R. 36 E. Garfield County, Montana on the extreme eastern edge of the petrographic province of Central Montana. They consist of dikes and plugs arranged in linear, en-echelon pattern with a northeast trend and intrude the Tullock member (Paleocene age)...
