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...
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...
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...

Radioactive equilibrium in ancient marine sediments
Irving A. Breger
1955, Geochimica et Cosmochimica Acta (8) 63-73
Radioactive equilibrium in eight marine sedimentary formations has been studied by means of direct determinations of uranium, radium and thorium. Alpha-particle counting has also been carried out in order to cross-calibrate thick-source counting techniques. The maximum deviation from radioactive equilibrium that has been noted is 11 per cent—indicating that there...

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...
Geology and ground-water resources of Webster County, Iowa
William E. Hale
1955, Water Supply Bulletin 4
Webster County, comprising an area of 718 square miles just northwest of the center of Iowa, had a population of 44,241 in 1950, with 25,115 in Fort Dodge, the principal city. Some 94.4 percent of the county is in farm land; corn is the principal crop and is used in...
The pygmy whitefish, Coregonus coulteri, in Lake Superior
Paul H. Eschmeyer, Reeve M. Bailey
1955, Transactions of the American Fisheries Society (84) 161-199
Bottom trawling by the U. S. Fish and Wildlife Service motor vessel Cisco in Lake Superior in 1952–1953 revealed a large population of a tiny whitefish, Coregonus (Prosopium) coulteri, which has been reported previously only from northwestern North America. The hiatus in range, from Lake Superior to the Columbia...
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 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...
Flood control problems

Throughout the world, alluvial soils are among the most fertile and easiest cultivated. Alluvial valleys are routes for transportation either by water or by road and railroad. Rivers are sources of water, a necessity of life. But these river valleys and alluvial deposits, which have so many desirable characteristics and...

1954, Special Scientific Report - Fisheries 138
Since 1951 a disease, usually occurring in late spring or early summer, has caused severe losses in 3- to 12-month-old fingerling sockeye salmon in hatcheries in the State of Washington.

Virus diseases of fish
Stanley W. Watson
1954, Transactions of the American Fisheries Society (83) 331-341
Viruses are probably the cause of a wide spectrum of fish diseases. Although relatively few virus diseases of fish are known today, some of the diseases of unknown etiology, as well as some diseases presently accepted as due to bacteria, protozoa, fungi or nutritional deficiencies, possibly will be recognized eventually...
