Preliminary report on the geology of San Nicolas Island, California
J. G. Vedder, J.E. Schoelhamer, M.C. Israelsky
1956, Open-File Report 56-126
The U. S. Geological Survey, at the request of the Director of Naval Petroleum Reserves, undertook a geologic investigation of San Nicolas Island, Ventura County California, in the spring of 1955. This preliminary report summarizes present knowledge concerning the general stratigraphy and structure of the island. Additional surface and underwater...
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...
