Airborne radioactivity surveys in geologic exploration
R.M. Moxham
1958, Trace Elements Investigations 662
The value of airborne radioactivity surveys in guiding uranium exploration has been well established. Recent improvements in circuitry and development of semiquantitative analytical techniques permit a more comprehensive evaluation of the geologic distribution of radioactive materials that may prove useful in exploration for other minerals and in regional geologic studies....
Suggestions to authors of the reports of the United States Geological Survey
U.S. Geological Survey
1958, Report
Knowledge acquired by the Geological Survey through programs of research and investigations has no value to the public if it remains in office files or in the minds of the scientists and engineers who did the work. The full discharge of the Survey's responsibilities is attained only by making its...
Apparatus and technique for multiple tests by the confined-spot method of colorimetric analysis: Application to field estimation of nickel and copper
J. H. McCarthy Jr., R.E. Stevens
1958, Analytical Chemistry (30) 535-538
The confined-spot method of colorimetric analysis is generally applicable to the semiquantitative estimation of traces of ions in solution that form colored precipitates or otherwise alter material on a confined area of reagent paper. For precise results, the rate of flow of test solutions through the reagent paper must be...
The water, deuterium, gas and uranium content of tektites
I. Friedman
1958, Geochimica et Cosmochimica Acta (14) 316-324
The water content, deuterium concentration of the water, total gas and uranium contents were determined on tektite samples and other glass samples from Texas, Australia, Philippine Islands, Java, French Indo-China, Czechoslovakia, Libyan Desert, Billiton Island, Thailand, French West Africa, Peru, and New Mexico. The water content ranges from 0.24 per...
Volumes and surface areas of pendular rings
W. Rose
1958, Journal of Applied Physics (29) 687-691
A packing of spheres is taken as a suitable model of porous media. The packing may be regular and the sphere size may be uniform, but in general, both should be random. Approximations are developed to give the volumes and surface areas of pendular rings that exist at points of sphere...
Biogeochemistry of the rare-earth elements with particular reference to hickory trees
W. O. Robinson, H. Bastron, K. J. Murata
1958, Geochimica et Cosmochimica Acta (14) 55-67
Hickory trees concentrate the rare-earth elements in their leaves to a phenomenal degree and may contain as much as 2300 p.p.m. of total rare earths based on the dry weight of the leaves. The average proportions of the individual elements (atomic percent of the total rare-earth elements) in the leaves...
The next decade in geochemistry
E. Ingerson
1958, Geochimica et Cosmochimica Acta (14) 185-203
The purpose, associations, functions; and activities of the Geochmical Society are reviewed briefly. Work on the Colorado Plateau uranium deposits is described as an example of what geochemical research, in conjunction with detailed field work, mineralogical studies, and related techniques can contribute to the understanding of a type of deposit....
Role of clay minerals in the transportation of iron
D. Carroll
1958, Geochimica et Cosmochimica Acta (14) 1-28
The clay minerals have iron associated with them in several ways:1.(1) as an essential constituent2.(2) as a minor constituent within the crystal lattice where it is in isomorphous substitution and3.(3) as iron oxide on the surface of the mineral platelets. Nontronite, “hydromica,” some...
