Bibliography and index of U.S. Geological Survey trace elements and related reports through June 1956
Paul E. Soister, Dora R. Conklin, Mary D. Bowman, Water Resources Division, U.S. Geological Survey
1956, Trace Elements Investigations 600
This bibliography supersedes TEI-500, "U. S. Geological Survey Trace Elements and related reports through 1954." Part I is a numerical list of U. S. Geological Survey Trace Elements Investigations and Memorandum reports. This part lists reports that have been transmitted to the U. S. Atomic Energy Comission and also reports...
Oxidation potential and state of some vanadium ores and the relation of woody material to their deposition
Alfred Michael Pommer
1956, Trace Elements Investigations 586
Oxidation potential studies with a multiple pH-potential recorder designed and constructed for this purpose demonstrated that some uranium-vanadium ores in the Colorado Plateau were in a reduced state when deposited. Any oxidation which took place occurred after deposition. Experimental and theoretical reducing studies on fresh wood, wood degraded by burial...
Distribution of uranium in the Bisbee district, Cochise County, Arizona
Stewart R. Wallace
1956, Trace Elements Investigations 426
The Bisbee district has been an important source of copper for many years, and substantial amounts of lead and zinc ore and minor amounts of manganese ore have been mined during certain periods. The copper deposits occur both as low-grade disseminated ore in the Sacramento Hill stock and as massive...
Summary of reconnaissance for radioactive deposits in Alaska, 1945-1954, and an appraisal of Alaskan uranium possibilities
Helmuth Wedow Jr.
1956, Trace Elements Investigations 577
In the period 1945-1954 over 100 investigations for radioactive source materials were made in Alaska. The nature of these investigations ranged from field examinations of individual prospects or the laboratory analysis of significantly radioactive samples submitted by prospectors to reconnaissance studies of large districts. In this period no deposits of...
Reflecting curved-crystal X-ray spectrograph; a device for the analysis of small mineral samples
I. Adler, J. M. Axelrod
1956, Economic Geology (52) 694-701
A curved-crystal reflecting spectrometer of the type described by Birks and Brooks of the Naval Research Laboratories, but adapted for use in mineralogical studies, has been built in the Geological Survey. It has been successfully applied to the analysis of tiny crystals, zones in minerals, and individual grains in mixed-mineral...
Discussion of “Some factors affecting rates of sedimentation in the Columbia River basin”
H.E. Thomas, E.M. Flaxman, R.L. Hobba
1956, Eos, Transactions, American Geophysical Union (37) 110-112
hydrologists are generally aware of the number and complexity of the variables that are encountered in all aspects of hydrology, and the great difficulty of analyzing these factors quantitatively because of inadequacy of basic data. Because of limitations in funds, time, or scientific manpower, it is likely that the basic...
The deuterium blance of Lake Maracaibo
Irving Friedman, Daniel R. Norton, D.B. Carter, A.C. Redfield
1956, Limnology and Oceanography (1) 239-246
A balance sheet for the gains and losses of deuterium from Lake Maracaibo, using estimates based on climatological data for the exchanges of water and measurements of the deuterium content of lake water, rainfall, river flow, and Caribbean Sea water to obtain the volumes of the deuterium exchange, indicates that...
Comparison of radiogenic helium and lead in zircon
Patrick M. Hurley, E. S. Larsen Jr., David Gottfried
1956, Geochimica et Cosmochimica Acta (9) 98-102
A direct comparison of helium and radiogenic lead in nonmetamict zircon crystals has indicated a 25 per cent discrepancy between these radiogenic constituents. It appears that the amount of helium is only three-quarters of the amount that should be present according to the content of radiogenic lead. Approximately the same...
Regional gravity survey in northeastern Oklahoma and southeastern Kansas
Kenneth L. Cook
1956, Geophysics (21) 88-106
In 1948 the U. S. Geological Survey, in cooperation with the U. S. Coast and Geodetic Survey, made a regional gravity survey in northeastern Oklahoma and southeastern Kansas in connection with the studies of the deflection of the vertical. About 550 gravity stations were occupied with spacings of 5 to...
Factors controlling the concentrations of thirteen rare metals in sea-water
K.B. Krauskopf
1956, Geochimica et Cosmochimica Acta (9) 1-32
The following factors controlling the concentrations of thirteen metals (Zn, Cu, Pb, Bi, Cd, Ni, Co, Hg, Ag, Cr, Mo, W, V) in sea-water were studied:1. precipitation of insoluble compounds with ions normally present in aerated sea-water,2. precipitation of sulphides locally in reducing environments,<br...
The progressive lag of sediment concentration with flood waves
Sumner Griggs Heidel
1956, Eos, Transactions, American Geophysical Union (37) 56-66
Numerous investigations of suspended‐sediment discharge have shown that an increase in stream flow usually is accompanied by an increase in sediment concentration. The sediment‐concentration peak during a rise may precede, coincide with, or follow the water‐discharge peak. Observations on the Bighorn River in Wyoming and Montana show a progressive lag...
A preliminary report on model studies of magnetic anomalies of three-dimensional bodies
Isadore Zietz, Roland G. Henderson
1956, Geophysics (21) 794-814
Model experiments were made to devise a rapid method for calculating magnetic anomalies of three-dimensional structures. The magnetic fields of the models were determined using the equipment at the Naval Ordnance Laboratory, White Oaks, Md. An irregularly shaped mass was approximated by an array of prismatic rectangular slabs of constant...
