Preliminary reconnaissance survey for thorium, uranium, and rare-earth oxides, Bear Lodge Mountains, Crook County, Wyoming
V.R. Wilmarth, Douglas H. Johnson
1953, Trace Elements Investigations 172
An area about 6 miles north of Sundance, in the Bear Lodge Mountains, in Crook County, Wyo., was examined during August 1950 for thorium, uranium, and rare-earth oxides and samples were collected. Uranium is known to occur in fluorite veins and iron-manganese veins and in the igneous rocks of Tertiary age...

1953, Trace Elements Memorandum 644
The accompanying maps show the results of an airborne radioactivity survey along the Atlantic Ocean beach from Cape Henry, Virginia to Cape Fear, North Carolina and from Savannah Bach Georgia to Miami Beach, Florida. The survey was made March 23-24, 1953, as part of a cooperative program with the U.S....
Distribution of coarse- and fire-grained rocks in the Wasatch formation and their relationship to uranium deposits, Powder River Basin, Wyoming
David F. Davidson
1953, Trace Elements Memorandum 676
A brief study of the areal distribution of the various rock types of the Wasatch formation in the Powder River Basin, Wyoming, was made during the summer of 1952. In the south and central parts if the basin, the Wasatch formation appears to contain coarser-grained rocks in contrast to...

Analysis of mixed-layer clay mineral structures
W. F. Bradley
1953, Conference Paper, Analytical Chemistry
Among the enormously abundant natural occurrences of clay minerals, many examples are encountered in which no single specific crystallization scheme extends through a single ultimate grain. The characterization of such assemblages becomes an analysis of the distribution of matter within such grains, rather than the simple identification of mineral species....
Technique for the application of a streamer-type fish tag
Leonard S. Joeris
1953, Transactions of the American Fisheries Society (82) 42-47
Principal features of the technique are: attachment of the plastic tag by means of a nylon-thread loop prepared in advance of field work; use of a curved surgical needle with cutting edge and a split eye for application of the tag. The procedures for splitting the needle's eye and for...
The movement of tagged lake trout in Lake Superior, 1950-52
Paul H. Eschmeyer, Russell Daly, Leo F. Erkkila
1953, Transactions of the American Fisheries Society (82) 68-77
A total of 733 native lake trout was tagged at two widely separated localities in Lake Superior; subsequent recaptures numbered 155 fish (21.1 percent) during the year following marking. In October 1950, 116 large lake trout (average total length, 27.3 inches) were tagged near Keweenaw Point, Michigan. Fifteen...
Determination of traces of cobalt in soils: A field method
H. Almond
1953, Analytical Chemistry (25) 166-167
The growing use of geochemical prospecting methods in the search for ore deposits has led to the development of a field method for the determination of cobalt in soils. The determination is based on the fact that cobalt reacts with 2-nitroso-1-naphthol to yield a pink compound that is soluble in...
Semiquantitative spectrographic method for analysis of minerals, rocks, and ores
C. L. Waring, C. S. Annell
1953, Analytical Chemistry (25) 1174-1179
The quantity and complex nature of materials received for analysis in the spectrographic laboratories of the U. S. Geological Survey have emphasized the need for a spectrographic method to determine a maximum number of elements in a limited time with a reasonable degree of accuracy. The semiquantitative method described determines...
Geochemical studies of clay minerals III. The determination of free silica and free alumina in montmorillonites
Margaret D. Foster
1953, Geochimica et Cosmochimica Acta (3) 143-154
Determination of free silica by the method proposed made possible the derivation of logical formulas for several specimens of montmorillonites for which the formulas could not be derived from the analyses alone. Other montmorillonites, for which logical formulas could be derived from their analyses, were found to contain small amounts...
Ultraviolet spectrophotometric determination of tantalum with pyrogallol
J. I. Dinnin
1953, Analytical Chemistry (25) 1803-1807
In a search for a more rapid method for the determination of tantalum in rocks and minerals, an intensive study was made of the tantalum-pyrogallol reaction recommended by Platanov and Krivoshlikov, and a better modified spectrophotometric procedure is given. The improved method consists in measuring the absorbancy of the tantalum-pyrogallol...
Quercetin as colorimetric reagent for determination of zirconium
F. S. Grimaldi, C. E. White
1953, Analytical Chemistry (25) 1886-1890
Methods described in the literature for the determination of zirconium are generally designed for relatively large amounts of this element. A good procedure using colorimetric reagent for the determination of trace amounts is desirable. Quercetin has been found to yield a sensitive color reaction with zirconium suitable for the determination...
Method for determination of small amounts of rare earths and thorium in phosphate rocks
C. L. Waring, H. Mela Jr.
1953, Analytical Chemistry (25) 432-435
In laboratory investigations, interest developed in the possible rare-earth content of phosphate samples from Florida and the northwestern United States. Because of the difficulty of making chemical determinations of traces of individual rare earths, a combined chemical-spectrographic method was investigated. After removal of iron by the extraction of the chloride...
Systematic variation of rare earths in monazite
K. J. Murata, H. J. Rose Jr., M. K. Carron
1953, Geochimica et Cosmochimica Acta (4) 292-300
Ten monazites from widely scattered localities have been analyzed for La, Ce, Pr, Nd, Sm, Gd, Y and Th by means of a combined chemical and emission spectrographic method. The analytical results, calculated to atomic percent of total rare earths (thorium excluded), show a considerable variation in the proportions of...

Water Resources Division, U.S. Geological Survey
1953, Report
This set of maps has been prepared to show the kinds of information, useful to engineers, that can be derived from ordinary geologic maps. A few additional bits of information, drawn from other sources, are mentioned below. Some of the uses of such maps are well known; they are indispensable...
Abbreviations used in publications of the United States Geological Survey
Water Resources Division, U.S. Geological Survey
1953, Report
The use of abbreviations in publications of the Geological Survey is determined by several forces working in different directions. Pulling in the direction of greater condensation and the freer use of abbreviations and symbols is the desire to achieve greater economy in publications. Working in the opposite direction is the...

War on lampreys
James W. Moffett
1953, Philadelphia Enquirer, 23 August 1953 16-17
Vampire-like sea lampreys look somewhat like short sections of garden hose, swim like eels, and live solely on the blood of fishes. Their voracious appetites have been especially harmful to fish in the Great Lakes, and it is there that methods of underwater electrocution are being applied in their...
