Nonsteady flow to a well of constant drawdown in an extensive aquifer
C.E. Jacob, S.W. Lohman
1952, Eos, Transactions, American Geophysical Union (33) 559-569
A mathematical theory is given for the discharge of a well of constant drawdown, discharging as by natural flow from an effectively infinite aquifer of uniform transmissibility and uniform compressibility. This theory is based on the solution by L. P. Smith of the analogous problem in heat conduction. The mathematical...

Radioactivity of nine samples of beach placer deposits in the Yakataga area, southern Alaska, was studied in 1948. The samples were given to the Geological Survey by prospectors operating in the area operating in the area. The heavy-mineral fractions from the concentrates average 0.044 percent equivalent uranium....
Compilation of data on the uranium and equivalent uranium content of samples analyzed by U.S. Geological Survey during a program of sampling mine, mill, and smelter products
Marlene Louise Hall, Arthur Pierce Butler Jr.
1952, Trace Elements Investigations 242
In 1942 the Geological Survey began to collect, in response to a request made by the War Production Board, samples of mine, mill, and smelter products. About 1,400 such samples were collected and analyzed spectrographically for about 20 elements that were of strategic importance, in order to determine whether any...
Garo uranium deposits, Park County, Colorado
Garland B. Gott
1951, Trace Elements Memorandum 222
The uranium deposits, three-fourths of a mile south of Garo, Park County, Colo., were mined over 30 years ago for radium ore. The old workings are now abandoned and inaccessible. Forty tons of ore that contained 1.0 percent uranium are reported to have been mined from two light-gray sandstone beds that are stratigraphically about...
Preliminary report on the correlation between gamma-ray logs and permeability logs of the ore-bearing sandstone in the Morrison Formation Calamity Mesa, Mesa County, Colorado
David A. Phoenix
1951, Trace Elements Memorandum 270
A study of the hydrologic properties and geologic relations of the ore-bearing sandstone in the Salt Wash sandstone member of the Morrison formation has been undertaken because uranium and vanadium are believed to have been introduced into the sandstone by circulating ground water. This report describes the geologic and hydrologic characteristics of the ore-bearing sandstone...
Preliminary report on geobotanical exploration in the Yellow Cat District, Grand County, Utah
Helen L. Cannon
1951, Trace Elements Memorandum 273
Two geobotanical methods of prospecting have been applied to the search for uranium deposits in the Yellow Cat district, Grand County, Utah. The first method is based on the absorption and accumulation of uranium by plants from underlying uranium deposits. To demonstrate this method, several hundred samples of Juniperus monosperma, Atriplex confert ifolia, and Cowania...

1951, Open-File Report 51-100
Ground-water studies in the Missouri River basin were begun by the United States Geological Survey during the fall of 1945 as a part of a program for the development of the resources of the basin by the United States Bureau of Reclamation and other Federal Agencies. The studies of the...
Reconnaissance of radioactive rocks of Maine
John M. Nelson, Perry F. Narten
1951, Trace Elements Investigations 68
The state of Maine was traversed with car-mounted Geiger-Mueller equipment in the late summer of 1948 and the radioactivity of approximately 4,600 miles of road was logged. All samples were analyzed, both in the field by comparing the radioactivity of each sample to the radioactivity of a stranded measured with a...
