Correlation of the Cretaceous formations of Greenland and Alaska
Ralph Willard Imlay, John B. Reeside Jr.
1953, Open-File Report 53-135
This is Number 10d of a series of correlation charts prepared for the Committee on Stratigraphy of the National Research Council. It has been sponsored by the U.S. Geological Survey and has required about seven months' time of both authors gathering and compiling data and evaluating fossil evidence. As...
Measurement of earth pressures by means of the flat jack test
P. Habib, R. Marchand, Severine Britt (translator)
1953, Open-File Report 54-31
This study deals with the principle and application of a method of measuring the stresses around a rock gallery. The measuring principle consists of cutting a drain in a gallery wall, observing the corresponding stress lessening, then restoring the initial state of stress by means of a Freyssinet flat jack. The...
Measurement of earth pressure in the iron-ore mines of eastern France
M.E. Tincelin
1953, Open-File Report 54-30
The purpose of the tests, which will be reported later, is to measure as precisely as possible the tangential stresses exerted on the periphery of a gallery cut in the Lorraine iron ore. The values of the tangential stresses along the periphery being known, they will be compared with the values...
Observation of a "front" of regional metamorphism
Rene Perrin, Marcel Roubault, S. H. Britt (translator)
1953, Open-File Report 54-32
Drawing his inspiration from the theories on metamorphism by reaction in the solid state, and from some observations, Rene Perrin in his article 'Perrin, Rene, Le metamorphisms generateur de plissement, Annales des Hines, Paris, October 1935.' "Metamorphism, the generator of folding" stated in 1935: 1) that some "sudden arrest" of regional...
Niobium (columbium) and titanium at Magnet Cove and Potash Sulphur Springs, Arkansas
Verne Charles Fryklund Jr., R. S. Harner, E.P. Kaiser
1953, Open-File Report 53-74
This work was done because niobium (columbium) has been found in several of the minerals and rocks of the Magnet Cove and Potash Sulphur Springs areas. Niobium is in demand for use in high-temperature and non-creep steels.The Magnet Cove and Potash Sulphur Springs areas are in central Arkansas between Malvern...
Reconnaissance for radioactive deposits in the Nixon Fork mining district, Medfra Quadrangle, central Alaska, 1949
Max G. White, John M. Stevens
1953, Trace Elements Investigations 75
Reconnaissance for radioactive deposits in the Nixon Fork mining district, Medfra quadrangle, central Alaska, in 1949 disclosed the occurrence of allanite in sampled containing as much as 0.05 percent equivalent uranium from the dump of the Whalen mine; the presence of radioactive parisite (a rare-earth fluocarbonate) in a highly altered...
Changes in chemical quality of the Arkansas River in Oklahoma and Arkansas (1946-52)
T.B. Dover, J.W. Geurin
1953, Open-File Report 53-289
Systematic chemical quality-of-water investigations have been carried on in both Oklahoma and Arkansas by the Geological Survey in cooperation with State and Federal agencies during the past several years. Results of the Survey's quality-of-water investigations are usually published in the annual Water-Supply Papers. However, as the Geological Survey has made...
Summary of annual records of chemical quality of water of the Arkansas River in Oklahoma and Arkansas, 1945-1952
Water Resources Division, U.S. Geological Survey
1953, Open-File Report 53-288
This report summarizes information collected to date in the Arkansas River Basin in Oklahoma and Arkansas, and shows, within the limitations of present information, the chemical quality of water in the Arkansas River downstream from the Oklahoma-Kansas State line to its junction with the Mississippi River, and the influence of...
Search for uranium in western United States
Vincent Ellis McKelvey
1953, Trace Elements Investigations 199
The search for uranium in the United States is one of the most intensive ever made for any metal during our history. The number of prospectors and miners involved is difficult to estimate but some measure of the size of the effort is indicated by the fact that about 500...
