Geology of the Wood and East Calhoun mines, Central City District, Gilpin County, Colorado
Avery Ala Drake
1955, Trace Elements Investigations 175
The Wood-East Calhoun mine area is underlain by complexly folded Precambrian gneiss and pegmatite. The major fold in the area is an anticline that trends about N. 60° E. The Precambrian rocks are intruded by bostonite porphyry dikes of Tertiary age. All the rocks are cut by east- to northeast...
Hawaiian Volcano Observatory record book 1955
1955, Report
The Hawaiian Volcano Observatory (HVO) record books are annual journals in which field observations of eruptive activity at Kīlauea and Mauna Loa volcanoes, on the Island of Hawaiʻi, were compiled by HVO staff for most years from 1912 through early 1966. In addition to descriptive observations, the record books also...

Reconnaissance for radioactive deposits in Alaska, 1953
John J. Matzko, Robert G. Bates
1955, Trace Elements Investigations 442
During the summer of 1953 the areas investigated for radioactive deposits in Alaska were on Nikolai Creek near Tyonek and on Likes Creek near Seward in south-central Alaska where carnotite-type minerals had been reported; in the headwaters of the Peace River in the eastern part of the Seward Peninsula and...

Airborne and ground reconnaissance of part of the syenite complex near Wausau, Marathon county, Wisconsin
R.C. Vickers
1955, Trace Elements Memorandum 742
Airborne and ground reconnaissance for radioactive minerals in part of the syenite complex near Wausau, Marathon county, Wis., found 12 radioactive mineral localities. The rocks in the area are of Precambrian age and consist of syenite and nepheline syenite, which have intruded older granite, greenstone, quartzite, and argillite....
Total sediment load measured in turbulence flume
Paul C. Benedict, Maurice L. Albertson, Donald Q. Matejka
1955, Transactions of the American Society of Civil Engineers (120) 457-484
The results of significant model tests in a glass-walled flume and prototype tests of a turbulence flume are presented. The velocity of flow and the transportation of the total sediment load in suspension were observed under varying conditions of flow. Also noted was the resistance to flow caused by vertical...

Automatic photometric titrations of calcium and magnesium in carbonate rocks
Leonard Shapiro, W. W. Brannock
1955, Analytical Chemistry (27) 725-728
Rapid nonsubjective methods have been developed for the determination of calcium and magnesium in carbonate rocks. From a single solution of the sample, calcium is titrated directly, and magnesium is titrated after a rapid removal of R2O3 and precipitation of calcium as the tungstate. A concentrated and a dilute solution...
Determination of thorium and of rare earth elements in cerium earth minerals and ores
M. K. Carron, D. L. Skinner, R.E. Stevens
1955, Analytical Chemistry (27) 1058-1061
The conventional oxalate method for precipitating thorium and the rare earth elements in acid solution exhibits definite solubilities of these elements. The present work was undertaken to establish conditions overcoming these solubilities and to find optimum conditions for precipitating thorium and the rare earth elements as hydroxides and sebacates. The...
Determination of boron in silicates after ion exchange separation
Henry Kramer
1955, Analytical Chemistry (27) 144-145
Existing methods for the determination of boron in silicates are not entirely satisfactory. Separation as the methyl ester is lengthy and frequently erratic. An accurate and rapid method applicable to glass, mineral, ore, and water samples uses ion exchange to remove interfering cations, and boron is determined titrimetrically in the...
Determination of small and large amounts of fluorine in rocks
F. S. Grimaldi, B. Ingram, F. Cuttitta
1955, Analytical Chemistry (27) 918-921
Gelatinous silica and aluminum ions retard the distillation of fluorine in the Willard and Winter distillation method. A generally applicable, simple method for the determination of fluorine in rocks containing aluminum or silicon or both as major constituents was desired. In the procedure developed, the sample is fused with a...
Field determination of microgram quantities of niobium in rocks
F. N. Ward, A. P. Marranzino
1955, Analytical Chemistry (27) 1325-1328
A rapid, simple, and moderately accurate method was needed for the determination of traces of niobium in rocks. The method developed is based on the reaction of niobium(V) with thiocyanate ion in a 4M hydrochloric acid and 0.5M tartaric acid medium, after which the complex is extracted with ethyl ether....
Composition and origin of basaltic magma of the Hawaiian Islands
H. A. Powers
1955, Geochimica et Cosmochimica Acta (7) 77-107
Silica-saturated basaltic magma is the source of the voluminous lava flows, erupted frequently and rapidly in the primitive shield-building stage of activity, that form the bulk of each Hawaiian volcano. This magma may be available in batches that differ slightly in free silica content from batch to batch both at...
Determination of thorium by fluorescent x-ray spectrometry
I. Adler, J. M. Axelrod
1955, Analytical Chemistry (27) 1002-1003
A fluorescent x-ray spectrographic method for the determination of thoria in rock samples uses thallium as an internal standard. Measurements are made with a two-channel spectrometer equipped with quartz (d = 1.817 A.) analyzing crystals. Particle-size effects are minimized by grinding the sample components with a mixture of silicon carbide...
Determination of total sulfur content of sedimentary rocks by a combustion method
M. E. Coller, R. K. Leininger
1955, Analytical Chemistry (27) 949-951
Total sulfur has been determined in common sedimentary rocks by a combustion method. Sulfur contents range from 0.001 to 5.0%. Experiments show that the combustion method can be used in analyzing sedimentary rocks in which sulfur is present as sulfide, sulfate, or both. Pulverized samples from 0.100 to 0.500 gram...
Molybdenum blue reaction and determination of phosphorus in waters containing arsenic, silicon, and germanium
H. Levine, J.J. Rowe, F. S. Grimaldi
1955, Analytical Chemistry (27) 258-262
Microgram amounts of phosphate are usually determined by the molybdenum blue reaction, but this reaction is not specific for phosphorus. The research established the range of conditions under which phosphate, arsenate, silicate, and germanate give the molybdenum blue reaction for differentiating these elements, and developed a method for the determination...
Theoretical effect of diffusion on isotopic abundance ratios in rocks and associated fluids
F. E. Senftle, J. T. Bracken
1955, Geochimica et Cosmochimica Acta (7) 61-76
Diffusion is considered as a possible process of isotope fractionation taking place throughout geologic time. Both diffusion in solids and diffusion in liquids are taken as possible mechanisms, the latter being more important. Arguments are presented to show that if significant fractionation takes place within a crystal by outward diffusion...
