Occurrence of diatomaceous earth near Kenai, Alaska
George Plafker
1955, Open-File Report 55-139
Diatomaceous earth occurs in post-glacial lake deposits exposed along the shore of Cook Inlet north of the village of Kenai, Alaska. Diatomaceous earth is an unconsolidated earthy deposit formed by accumulation of the minute siliceous tests (skeletons) of diatoms, a type of algae. Diatomaceous earth is sometimes referred to...
Electrical resistivity measurements in the Neillsville area, Wisconsin
H. Cecil Spicer, George J. Edwards
1955, Open-File Report 55-173
Sixty-eight electrical depth profiles were completed in the vicinity of Neillsville, Wis. to obtain information on the water-bearing beds in the glacial moraine and consolidated sedimentary rocks in the area. No productive aquifers were found but the best areas for test drilling are described. The basic theory and interpretation procedures,...
Status of ownership of part of the lands on which phosphate-bearing beds outcrop in southwestern Montana and northeastern Idaho
Emerson C. Willey, E. R. Cressman, H.W. Peirce, T. M. Cheney
1955, Open-File Report 55-197
This report and accompanying maps summarize the status or ownership or many phosphate bearing lands in southwestern Montana and northeastern Idaho. Ownership categories discussed are (1) phosphate rights owned by Federal Government, (2) phosphate rights not owned by Federal Government, and (3) ownership status uncertain....
Uranium deposits of the northern part of the Boulder Batholith, Montana
George E. Becraft
1955, Trace Elements Memorandum 944
Uranium minerals and radioactivity anomalies occur in many silver-lead veins and chalcedony veins and vein zones in the Boulder batholith of southwestern Montanao Pitchblende has been identified in a few silver-lead veins. These veins occupy shear zones along which there is no evidence of large-scale lateral displacement. The wall rock...
Reconnaissance for uranium in asphalt-bearing rocks in the western states
William James Hail Jr.
1955, Trace Elements Investigations 559
An appraisal of asphalt-bearing rocks as potential sources of uranium was made during 1953 and 1954 by examining deposits in 45 areas in California, Utah, Wyoming, Montana, New Mexico, Texas, Oklahoma, and Missouri.  A total of 202 samples from these areas was analyzed for uranium. The oldest rocks sampled are...
Stratigraphy of the area between Hernando and Hardee counties, Florida
Keith B. Ketner, Laurence J. McGreevy
1955, Trace Elements Investigations 524
Eocene, Oligocene, Miocene, and Recent rocks are exposed between Hernando and Hardee Counties. Eocene and Oligocene formations are fossiliferous limestones but Miocene rocks are largely unconsolidated sands and clays in which fossils are scarce. Correlation of Miocene strata therefore is necessarily based mainly on lithology and stratigraphic position. Where rocks are altered...
Conglomeratic sandstone strata at the base of the Brushy Basin member of the Morrison formation as related to uranium-vanadium deposits, southwestern Colorado and southeastern Utah
David A. Phoenix
1955, Trace Elements Investigations 565
In southwestern Colorado and southeastern Utah strata of conglomeratic sandstone are localized at the base of the Brush Basin shale member of the Morrison formation of Jurassic age. These strata are discrete lithologic units that contain sedimentary structures oriented in a prevailing easterly direction, they locally rest upon sandstone in...
Some physical properties of naturally irradiated fluorite
Robert Berman
1955, Trace Elements Investigations 569
Five samples of purple fluorite found in association with radioactive, materials, and a synthetic colorless control sample were studied and compared.  Before and after heating, observations were made on specific gravity, index of refraction, unit-cell size, breadth of X-ray diffraction lines, and fluorescence.  The purple samples became colorless on heating...
