Preliminary report on uranium deposits in the Miller Hill area, Carbon County, Wyoming
J. D. Love
1953, Trace Elements Investigations 315
A sequence of radioactive rocks of Miocene (?) age, the Browns Park formation, in the Miller Hill area of southern Wyoming is more than 1,000 feet thick. The formation crops out in an area of approximately 600 square miles, and consists of a basal conglomerate, tuffs, tuffaceous limy sandstones, and...
Radioactive deposits of Nevada
T.G. Lovering
1953, Trace Elements Investigations 169
Thirty-five occurrences of radioactive rocks had been reported from Nevada prior to 1952. Twenty-five of these had been investigated by the U. S. Geological Survey and the U. S. Atomic Energy Commission. Of those investigated, uranium minerals were identified in 13; two contained a thorium mineral (monazite); the source...
Radiometric reconnaissance in the Garfield and Taylor park quadrangles, Chaffee and Gunnison counties, Colorado
M.G. Dings, Max Schafer
1953, Trace Elements Investigations 255
During the summer of 1952 most of the mines and prospects in the Garfield and Taylor Park quadrangles of west-central Colorado were examined radiometrically by the U. S. Geological Survey to determine the extent, grade, and mode of occurrence of radioactive substances. The region contains a relatively large number of rock...
The geology and mineralogy of the W. Wilson mine near Clancey, Jefferson County, Montana
D.Y. Meschter
1953, Trace Elements Investigations 256
The W. Wilson mine, near Clancey, Mont., explores a siliceous vein in quartz monzonite of the Boulder batholith. The vein is a composite structure that consists of several closely spaced veinlets of quartz and chalcedony separated by silicified quartz monzonite. The vein has been recurrently brecciated and silicified. Typically, the...
Progress report of southeastern monazite exploration, 1952
W.C. Overstreet, P. K. Theobald Jr., A. M. White, N. P. Cuppels, D. W. Caldwell, J. W. Whitlow
1953, Trace Elements Investigations 349
Reconnaissance of placer monazite during the field season of 1952 covered 6,600 square miles drained by streams in the western Piedmont of Virginia 5 North Carolina, South Carolina,, and Georgia. Emphasis during this investigation was placed on the area between the Savannah River at the border of South Carolina and...
Beaverhead formation, a Laramide deposit in Beaverhead County, Montana
W.R. Lowell, M. R. Klepper
1953, Geological Society of America Bulletin (64) 235-244
The name Beaverhead formation is proposed for a thick sequence of conglomerate, sandstone, siltstone, and limestone that crops out over an area of at least 400 square miles in Beaverhead County, Montana, extends southward across the Montana-Idaho boundary, and may extend eastward into Madison County. These rocks are clearly sedimentary...
Geology of the west-central part of the Gunnison Plateau, Utah
Clyde T. Hardy, Howard D. Zeller
1953, Geological Society of America Bulletin (64) 1261-1278
A detailed study of the west-central part of the Gunnison Plateau, Utah, has disclosed stratigraphic and structural relations important in the geological history of central Utah. The area mapped includes the eastern half of the Axtell No. 2 quadrangle, Manti area (U. S. Dept. of Agriculture, Soil Conservation Service).The bedrock...
Limestone walls of Okinawa
D.E. Flint, Gilbert Corwin, M.G. Dings, W.P. Fuller, F. S. MacNeil, Raymond A. Saplis
1953, Geological Society of America Bulletin (64) 1247-1260
Wall-like ridges of limestone that stand well above the surrounding terrain are an interesting phenomenon on the island of Okinawa. These ridges rim a variety of topographic features, but all are believed to represent the same formative processes. Rimming ridges or walls occur along the banks of streams crossing areas...
Iron deposits of the congonhas district, minas Gerais, Brazil
P. W. Guild
1953, Economic Geology (48) 639-676
Various origins have been proposed for the itabirite and associated hematite ores of Minas Gerais, Brazil. The U.S. Geological Survey, in cooperation with the Brazilian Departamento Nacional da Produqao Mineral, has undertaken a comprehensive program of mapping of these Precambrian deposits, which bear many similarities to other Precambrian iron formations....
Discussion of “the efficiency of depth‐integrating suspended‐sediment sampling”
R. F. Kreiss, B. R. Colby, Ning Chien
1953, Eos, Transactions, American Geophysical Union 796-797
The author has developed equations and approximate curves to express the percentage of the total sediment discharge that is carried in suspension above the lowest point reached by the nozzle of a depth‐integrating sediment sampler. He assumes that bed load and suspended load are defined by the equations in a...
Stratigraphic sections of the phosphoria formation in Idaho, 1950-51
R.A. Smart, R.G. Waring, T. M. Cheney, R.P. Sheldon
1953, Trace Elements Investigations 376
The U.S. Geological Survey has recently measured and sampled the Phosphoria formation at many localities in Idaho and other western states. These data will not be fully synthesized and analyzed for several years, but segments of the data, accompanied by little or no interpretation, are published as preliminary reports as...
Reconnaissance of superficial phosphate deposit near Minas, Uruguay
E.B. Eckel, C. Milton
1953, Economic Geology (48) 437-446
The phosphate deposit in Uruguay described here is of interest primarily because it is believed to be a superficial deposit that resulted from the action of guano on volcanic rock. Even though some of the rock contains as much as 30 per cent P206, it is unavailable as a source...
