Uranium migration and geochemistry of uranium deposits in sandstone above, at, and below the water table; Part 1, Calculation of apparent dates of uranium migration in deposits above and at the water table
John Nicholas Rosholt Jr.
1961, Economic Geology (56) 1392-1403
The migration of U may be studied by the distribution of the radioactive daughter products, which serve as natural tracers in the migration of U. The distribution of the daughter products is determined by radiochemical analyses of samples from ore deposits in sandstone, and the apparent minimum and maximum dates...
Origin of a salt-water lens in permafrost at Kotzebue, Alaska
D.J. Cedarstrom
1961, Bulletin of the Geological Society of America (72) 1427-1431
Frozen sediments were found to a depth of 238 feet in the drilling of a 325-foot well at Kotzebue, Alaska. Between 79 and 86 feet, however, highly saline water was found in a gravel lens. The writer suggests that the salt water originated by fractionation by freezing. Analyses of this water and of slightly saline...
Late quaternary history of the snake river in the American Falls region, Idaho
Donald E. Trimble, Wilfred James Carr
1961, Bulletin of the Geological Society of America (72) 1739-1748
While mapping the American Falls region, we found evidence that contributes to the middle Pleistocene to Recent history of the Snake River, and indirectly to the history of overflow of Lake Bonneville. Middle Pleistocene to recent rocks in the valley are mainly lacustrine and fluvial silts and clays, with some...
Sex ratios and age raios in North American ducks
Frank C. Bellrose, Thomas G. Scott, Arthur S. Hawkins, Jessop B. Low
1961, Illinois Natural History Survey Bulletin (27) 391-474
The sex classes and age classes of various species of ducks constitute measurable elements of the populations. The present study deals primarily with sex ratios and age ratios and the ways in which they relate to population productivity. The present study is an evaluation of sex and age ratios in...
Dating desert ground water
L. Thatcher, M. Rubin, Glen F. Brown
1961, Science (134) 105-106
Tritium in Arabian rainfall has followed the trend observed in North America with peaks in 1958 and the spring of 1959. These measurements will be useful for future hydrologie studies. Water from wadi gravels averages 10 yr old. Carbon-14 measurements of deep waters indicate ages of several thousand years....
Use of water-well data in interpreting occurrence of aquifers in northeastern Lyon County, Minnesota
Harry G. Rodis
1961, GSA Bulletin (72) 1275-1278
In northeastern Lyon County the areal distribution of aquifers of Cretaceous age determined from well-bottom altitudes suggests a series of interbedded sandstones striking northwestward and overlapping one another to the northeast. Probably the numerous thin sandstone aquifers in the area were deposited near the flanks of a Precambrian granite “high”...
Jadeite deposits of the clear creek area, New Idria district, San Benito county, California
R. G. Coleman
1961, Journal of Petrology (2) 209-247
Tectonic inclusions within the New Idria serpentine body contain jadeite in two distinct assemblages: (1) Lenslike inclusions containing a monomineralic green jadeite core surrounded by a calc-silicate rim. (2) Jadeite veins cross-cutting albite-crossite schist inclusions. In these veins jadeite coexists with low albite; green jadeite (Jd 75 Ac+Di+He 25)...
Copper, vanadium, and uranium deposits in sandstone-their distribution and geochemical cycles
R. P. Fischer, J. H. Stewart
1961, Economic Geology (56) 509-520
Deposits of copper, vanadium, and uranium in nonmarine sandstones are numerous and widespread. Copper deposits, with or without uranium, are mainly resident in first-generation arkosic sandstones derived from granitic rock terrains; deposits rich in vanadium, with or without much uranium, are dominantly in second-generation sandstones derived from sedimentary rocks; and the uranium deposits with little...
Late pleistocene and recent accumulation of uranium in ground water saturated sandstone deposits
J.M. Rosholt
1961, Economic Geology (56) 423-430
Protactinium-231 and thorium-230 relations in several ground water saturated sandstones containing uranium ore indicate that much of the uranium has been accumulating in very recent times. Samples from the Hauber mine, Crook County, Wyoming, were selected to illustrate the concept of recent accumulation and the methods of calculation of the estimated minimum and maximum dates of the...
Ground-water control in the Neyveli lignite field, South Arcot district, Madras State, India
P.H. Jones, V. Subramanyam
1961, Economic Geology (56) 273-298
Unconsolidated deposits of the Cuddalore series of Miocene age underlie much of the coastal plain of southern Madras. Several lignite seams occur in a thick sequence of sand, gravel, and clay that dips seaward about 40 to 100 feet per mile. The principal seam of lignite mapped in the Neyveli area averages more than 50...
