Some aspects of the origin of the Ironwood iron-formation of Michigan and Wisconsin
N.K. Huber
1959, Economic Geology (54) 82-118
The Ironwood iron-formation of the Gogebic Range of Michigan and Wisconsin is made up of several rock types, each of which is characterized by a different iron-rich mineral: hematite, magnetite, pyrite, iron carbonate, or iron silicate (minnesotaite, stilpnomelane). Where the Ironwood iron-formation is relatively unaltered the Plymouth, Norrie, and Anvil...
Role of fluid pressure in mechanics of overthrust faulting: II. Overthrust belt in geosynclinal area of western Wyoming in light of fluid-pressure hypothesis
William W. Rubey, M. King Hubbert
1959, GSA Bulletin (70) 167-206
Pressures of interstitial fluids significantly greater than the normal hydrostatic pressure are known in many parts of the world. Many occurrences are in thick sections of relatively young sediments; some are in areas that have been intensely deformed. Abnormal fluid pressures in the Gulf Coast region are associated with thick...
Water‐level fluctuations caused by Montana earthquake
Jose Alves Da Costa
1959, Eos, Transactions, American Geophysical Union (40) 346-346
The major earthquake of August 17, 1959, near the Montana‐Wyoming border had marked effects on water levels and artesian pressures in wells throughout the United States. Preliminary reports from field offices of the U. S. Geological Survey in 21 states show that water‐level fluctuations were automatically recorded in 136 observation...
History of Imuruk Lake, Seward Peninsula, Alaska
David M. Hopkins
1959, GSA Bulletin (70) 1033-1046
A study of Imuruk Lake, a large, shallow lake in north-central Seward Peninsula, Alaska, illuminates the climatic history of northwestern Alaska and the tectonic history of central Seward Peninsula during Pleistocene and Recent time. Special interest attaches to the older lake sediments, because they contain evidence concerning the climate, fauna, and...
Water analysis
L. L. Thatcher, R.T. Kiser
1959, Analytical Chemistry (31) 776-789

Primary borates in playa deposits: Minerals of high hydration
Siegfried J. Muessig
1959, Economic Geology (54) 495-501
The primary borate minerals in nonmarine bedded borate deposits - those of the playa type, and their deformed derivatives - are the high hydrates. Both field and laboratory data indicate that the high hydrates are the borate minerals that form stable phases at the lowest temperatures: under the surface conditions...
The relation between fresh and salty ground water in southern Nassau and southeastern Queens counties, Long Island, New York
Nathaniel M. Perlmutter, J. J. Geraghty, J. E. Upson
1959, Economic Geology (54) 416-435
An investigation of the geology and ground-water conditions in a part of southwestern Long Island, including the construction of 8 deep and 5 shallow test and observation wells, has been completed by the Geological Survey in cooperation with the Nassau County Department of Public Works and the New York State Water Power and Control Commission.<span...
Geology and uranium-vanadium deposits of the slick rock district, San Miguel and Dolores counties, Colorado
D. R. Shawe, Norbert L. Archbold, G. C. Simmons
1959, Economic Geology (54) 395-415
Sedimentary rocks known in the Slick Rock district in southwestern Colorado range in age from Devonian (?) to Cretaceous, and aggregate about 13,000 feet in maximum thickness. Important uranium-vanadium production has come from deposits in the Salt Wash member of the Morrison formation of Late Jurassic age.The sedimentary rocks are gently folded in...
Ground-water provinces of India
George C. Taylor
1959, Economic Geology (54) 683-697
This paper gives a general resume of ground-water utilization and development and describes the occurrence of water in eight ground-water provinces of India. The paper is based in part on observations of the writer during 1951-55 and in part on earlier work of the Geological Survey of India. Ground water...
Tritium and deuterium content of atmospheric hydrogen
F. Begemann, Irving Friedman
1959, Zeitschrift fur Naturforschung A (14) 1024-1031
The tritium and deuterium content of 24 samples of atmospheric hydrogen collected at ground level near Buffalo. N.Y. (U.S.A.). Hamburg (Germany), and Nürnberg (Germany) during 1954 to 1956 was measured.At the beginning of 1954 the T/H-ratio was found to have been 9.18 · 10-14 i.e. about a factor of 10 higher...
Some phase relations in the hydrothermally altered rocks of porphyry copper deposits
Saville Cyrus Creasey
1959, Economic Geology (54) 351-373
The application of ACF and AKF diagrams to the hydrothermal alteration in porphyry Cu deposits aids in the recognition of the critical components, and the characteristic mineral phases permit the distinction of one alteration facies from another. The somewhat meager chemical and mineralogical data suggest...
A Summary interpretation of geologic, hydrologic, and geophysical data for Yucca Valley, Nevada test site, Nye County, Nevada
Verl Richard Wilmarth, D.L. Healey, Alfred Clebsch Jr., I.J. Winograd, Isadore Zietz, H. W. Oliver
1959, Trace Elements Investigations 358
This report summarizes an interpretation of the geology of Yucca Valley to depths of about 2,300 feet below the surface, the characteristics features of ground water in Yucca and Frenchman Valleys, and the seismic, gravity, and magnetic data for these valleys. Compilation of data, preparation of illustrations, and writing of...
