A field instrument for quantitative determination of beryllium by activation analysis
William W. Vaughn, E.E. Wilson, J.M. Ohm
1960, Circular 427
A low-cost instrument has been developed for quantitative determinations of beryllium in the field by activation analysis. The instrument makes use of the gamma-neutron reaction between gammas emitted by an artificially radioactive source (Sb124) and beryllium as it occurs in nature. The instrument and power source are mounted in a...
Flood-frequency analyses, Manual of Hydrology: Part 3
Tate Dalrymple
1960, Water Supply Paper 1543-A
This report describes the method used by the U.S. Geological Survey to determine the magnitude and frequency of momentary peak discharges at any place on a stream, whether a gaging-station record is available or not. The method is applicable to a region of any size, as a river basin or...
Evaporation control research, 1955-58
Robert R. Cruse, Guy Earl Harbeck
1960, Water Supply Paper 1480
One hundred fifty-two compounds and compositions of matter were screened as potential evaporation retardants. The homologous straight-chain fatty alkanols are considered the best materials for retardants. Several methods of application of the alkanols to the reservoir surface were investigated. Although wick-type drippers for the application of liquids and cage rafts...
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 -...
Geology and ore deposits of the Klondike Ridge area, Colorado
John David Vogel
1960, Open-File Report 60-145
The region described in this report is in the northeastern part of the Colorado Plateau and is transitional between two major structural elements. The western part is typical of the salt anticline region of the Plateau, but the eastern part has features which reflect movements in the nearby San Juan...
