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...
The influence of ground‐water storage on the runoff in the San Bernardino and eastern San Gabriel Mountains of Southern California
Harold C. Troxell
1953, Eos, Transactions, American Geophysical Union (34) 552-562
The steep and rugged mountains of Southern California contain considerable ground‐water storage. A large portion of the runoff is seepage from this storage The variations in runoff distribution depend on the geology, physiography, and soil cover of these mountain areas....
Pumping from wells on the floor of the Sevier Desert, Utah
W.B. Nelson, H.E. Thomas
1953, Eos, Transactions, American Geophysical Union (34) 74-84
Data collected at the Topaz Relocation Center provide an excellent record of the development and subsequent disappearance of a cone of depression caused by pumping. This Center occupied temporarily an area of natural ground‐water discharge on the floor of the Sevier Desert in west‐central Utah. Water for a population of 6500 was pumped from artesian wells which tapped aquifers...
High Plains, or Llano Estacado, Texas-New Mexico
Carl H. Gaum
1953, Book chapter, The physical and economic foundation of natural resources; Volume 4: Subsurface facilities of water management and patterns of supply, type area studies
No abstract available....
Reconnaissance for radioactive deposits in the Fairbanks and Livengood Quadrangles, east-central Alaska, 1949
H. Wedow Jr., J.M. Stevens, G.E. Tolbert
1953, Trace Elements Investigations 197
Several mines and prospects in the Fairbanks and Livengood quadrangles, east-central Alaska, were examined for the possible presence of radioactive materials in the summer of 1949. Also tested were pre-Cambrian and Paleozoic metamorphic and sedimentary rocks crossed by the Elliott Highway, which extends from Fox, near Fairbanks, northward about 70...
Uranium deposits at Shinarump Mesa and some adjacent areas in the Temple Mountain district, Emery County, Utah
Donald G. Wyant
1953, Trace Elements Investigations 51
Deposits of uraniferous hydrocarbons are associated with carnotite in the Shinarump conglomerate of Triassic age at Shinarump Mesa and adjacent areas of the Temple Mountain district in the San Rafael Swell of Emery County, Utah. The irregular ore bodies of carnotite-bearing sandstone are genetically related to lenticular uraniferous ore bodies...
Ground-water conditions in artesian aquifers in Brown County, Wisconsin
William James Drescher
1953, Water Supply Paper 1190
The principal water-bearing rocks underlying Brown County, Wis., are thick sandstone units of Cambrian and Ordovician age. Other aquifers include limestone and dolomite of Ordovician age, dolomite of Silurian age, and sands and gravel of Pleistocene and Recent age. Underlying the water-bearing formations are crystalline rocks of pre-Cambrian age which...
