Uranium in the Upper Cambrian black shale of Sweden
Vincent Ellis McKelvey
1955, Trace Elements Investigations 495
The Peltura zone of the Upper Cambrian black shales of Sweden contains about 0.02 percent uranium. Maximum amounts are present in rocks deposited in an embayment in the sea and in rocks in or closely adjacent to that part of the vertical sequence that contains maximum amounts of distillable oil,...
Radioactivity and uranium content of some Cretaceous shales, central Great Plains
Harry A. Tourtelot
1955, Trace Elements Investigations 298
The Sharon Springs member of the Pierre shale of Cretaceous age, a hard black organic-rich shale similar to the Chattanooga shale, is radioactive throughout central and western South Dakota, most of Nebraska, northern Kansas, and northeastern Colorado. In the Missouri River valley, thin beds of the shale contain as much...

Uranium-bearing minerals in placer deposits of the Red River Valley, Elk City district, Idaho County, Idaho
F.C. Armstrong, P. L. Weis
1955, Trace Elements Investigations 562
Uranium-bearing multiple oxide minerals were first recognized in the jig-bed concentrate of !the Tyee Mining Company'ss gold dredge on the Red River about 10 miles south of Elk City. Idaho County, Idaho, in late 1951 or early 1952. The gravels of the placer deposits were derived from the Idaho batholith...

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...

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....
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 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...
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...

Some contributions of the Cooperative Wildlife Research Units to forest wildlife management
Daniel L. Leedy
1955, Journal of Forestry (53) 630-635
Although the Cooperative Wildlife Research Unit Program is nationwide in scope and has been in existence since 1935, it is probable that many readers of the Journal of Forestry are unaquainted with the program's objectives and accomplishments. This paper was written at the suggestion of a S.A.F. member to provide...

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...
