The volcano letter: A weekly news leaflet of the Hawaiian Volcano Research Association - 1955
1955, Report
The Volcano Letter was an informal publication issued at irregular intervals by the Hawaiian Volcano Observatory (HVO) during the years 1925 to 1955. Individual issues contain information on volcanic activity, volcano research, and volcano monitoring in Hawaii. Information on volcanic activity at other locations is also occasionally included.The Volcano Letter...

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...
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....

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...

Internal standards in fluorescent X-ray spectroscopy
I. Adler, J. M. Axelrod
1955, Spectrochimica Acta (7) 91-99
The use of internal standards in the analysis of ores and minerals of widely-varying matrix by means of fluorescent X-ray spectroscopy is frequently the most practical approach. Internal standards correct for absorption and enhancement effects except when an absorption edge falls between the comparison lines or a very strong emission...
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...
Germanium and uranium in coalified wood from upper Devonian black shale
Irving A. Breger, J. M. Schopf
1955, Geochimica et Cosmochimica Acta (7) 287-293
Microscopic study of black, vitreous, carbonaceous material occurring in the Chattanooga shale in Tennessee and in the Cleveland member of the Ohio shale in Ohio has revealed coalified woody plant tissue. Some samples have shown sufficient detail to be identified with the genus Cauixylon....

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...

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...
