Application of the modified Einstein procedure for computation of total sediment load
K. B. Schroeder, C. H. Hembree
1956, Eos, Transactions, American Geophysical Union (37) 197-212
A method that enables good estimates to be made of total sediment load has been tested with data from several western streams. The method, which uses both theoretical and empirical formulas, combines a modification of Einstein's procedure for computing bed‐material load and the usually available data from suspended‐sediment measurements. Basic...
Non-pegmatitic resources of beryllium in United States
Lawrence Allen Warner, W.T. Holser, V.R. Wilmarth, E.N. Cameron
1956, Trace Elements Investigations 137
During the period from 1948 to 1950 the U.S. Geological Survey conducted a program of field and laboratory research w determine the mode of occurrence of beryllium in non-pegmatitic rocks and mineral deposits as part of the Beryllium Program of the Division of Raw Materials of the U.S. Atomic Energy Commission. Approximately 23...
Some limitations on the possible composition of the ore-forming fluid
Paul B. Barton Jr.
1956, Trace Elements Investigations 633
The activity rations of various important anions (S, CO3, SO4, OH, F, and Cl) in hydrothermal solutions at the time of deposition are evaluated using a simple thermodynamic technique. The rations are interpreted in the light of the mineralogy of ore deposits and limites are placed on the variability of...
Volumetric determination of uranium using titanous sulfate as reductant before oxidimetric titration
James S. Wahlberg, Dwight L. Skinner, Lewis F. Rader
1956, Trace Elements Investigations 614
A new method for determining uranium in samples containing 0.05 percent or more U3O8, using titanous sulfate as reducing agent, is much shorter, faster, and has fewer interferences than conventional methods using reductor columns. The sample is dissolved with sulfuric, nitric, perchloric, and hydrofluoric acids. Elements that would otherwise form insoluble...
Radiometric traverse along the Yukon River from Fort Yukon to Ruby, Alaska, 1949
Max G. White, John M. Stevens, John J. Matzko
1956, Trace Elements Memorandum 357
In 1949, a radiometric traverse was made of rocks exposed along the banks of and near the Yukon River about Fort Yukon to Ruby, Alaska. Granitic rocks of Tertiary age and of Devonian or Carboniferous age and sandstone beds of Cretaceous age gave the highest readings obtained in the...

The physical behavior and geologic control of radon in mountain streams
Allen S. Rogers
1956, Trace Elements Investigations 619
Radon measurement were made in several small, turbulent mountain streams in the Wasatch Mountains near Salt Lake City and Ogden, Utah, to determine the relationship between the distribution of radon and its geologic environment. In this area, the distribution of radon in streams can be sued to locate points where relatively...
Geology and ore deposits of the Chicago Creek area, Clear Creek County, Colorado
J. E. Harrison, J. D. Wells
1956, Trace Elements Investigations 432
The Chicago Creek area, Clear Creek County, Colo., forms part of the Front Range mineral belt, which is a northeast-trending belt of coextensive porphyry intrusive rocks and hydrothermal veins of Tertiary age. More than $4.5 million worth of gold, silver, copper, lead, zinc, and uranium was produced from the mines...
