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...
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...
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...

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...
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...

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....

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...
Interpreting geologic maps for engineering purposes: Hollidaysburg quadrangle, Pennsylvania
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...
Ground-water conditions in artesian aquifers in Brown County, Wisconsin
William James Drescher
1953, Water Supply Paper 1190
The principal water-bearing rocks underlying Brown County, Wis., are thick sandstone units of Cambrian and Ordovician age. Other aquifers include limestone and dolomite of Ordovician age, dolomite of Silurian age, and sands and gravel of Pleistocene and Recent age. Underlying the water-bearing formations are crystalline rocks of pre-Cambrian age which...
The use of soils and paleosols for interpreting geomorphic and climatic history of arid regions
John Miller, Luna Bergere Leopold
1953, Research Council of Israel Special Publication 2
The study of modern surface soils, and ancient weathering zones, which occur either buried or as surface relicts, has contributed materially to understanding the complex events of the glacial and post-glacial period both in glaciated areas and in regions not influenced by glaciation. Most work of this kind in the...

The Quartz Creek pegmatite district includes an area about 29 square miles in the vicinity of Quartz Creek in Gunnison County,. Colo. This area contains 1,803 pegmatites that are intruded into pre-Cambrian rocks. The rocks exposed in the district range in age from pre-Cambrian to Recent. The oldest pre-Cambrian rocks are...

The Fourmile area, Custer County, S. Dak., is in pre-Cambrian metamorphic rocks that surround the granitic core of the Black Hills. The area is on the upright limb of an overturned anticline that plunges about 30° S. 10° E. Three new formations of metamorphic rocks are described that have a total...
