Preliminary report on the stratigraphy and structure of the Shaviovik and upper Sagavanirktok Rivers area, Alaska
A. Samuel Keller, Robert L. Detterman
1951, Geological Investigations, Naval Petroleum Reserve No. 4, Alaska 36
During the 1951 field season, U. S. Geological Survey Navy Oil Unit party 1 conducted stratigraphic and structural studies of the rocks in the area between the westernmost fork of the Shaviovik River and the East Kuparuk River. This area is drained by the Sagavanirktok River and its major tributaries;...

Geologic guides to prospecting for carnotite deposits on the Colorado Plateau
Doris H. Blackman Weir
1951, Trace Elements Investigations 119
This report describes the geologic features that can be used to appraise the favorability of ground in guiding diamond-drill exploration for carnotite deposits in the Upper Jurassic Morrison formation on the Colorado Plateau. It is based on a statistical study of the geologic logs of about 2,500 holes drilled...
Older Precambrian structure in Arizona
Charles A. Anderson
1951, Geological Society of America Bulletin (62) 1331-1346
The older Precambrian rocks of Arizona include the Vishnu, Yavapai, and Pinal schists, all overlain unconformably by nonmetamorphosed younger Precambrian rocks. The older Precambrian schists, unnamed gneisses, and associated granitic masses crop out in many of the mountain ranges southwest of the Colorado plateau. The stratigraphy and structure of the schists can be unraveled to some extent by detailed mapping, and work now in progress by...
Geologic history of sea water: An attempt to state the problem
William W. Rubey
1951, Geological Society of America Bulletin (62) 1111-1148
Paleontology and biochemistry together may yield fairly definite information, eventually, about the paleochemistry of sea water and atmosphere. Several less conclusive lines of evidence now available suggest that the composition of both sea water and atmosphere may have varied somewhat during the past; but the geologic record indicates that these...
Report of the Committee on Ground Water, 1949–1950
S.W. Lohman
1951, Eos, Transactions, American Geophysical Union (32) 769-772
The present report concludes the duties of the above Committee, and the Chairman takes this opportunity to thank the members and others for their splendid cooperation during the triennium ended June 30, 1950. Another in the series of reports on hydrology and physiography of limestone terranes, by A. C. Swinnerton, is given as...

Geochemical techniques as applied in recent investigations in the Tintic District, Utah
H. T. Morris
1951, Economic Geology (46) 608-625
Field techniques for the rapid extraction and estimation of copper, lead, and zinc from altered rock are described, together with their application in the Tintic district, Utah. Either sulfuric acid or an acetic acid-ammonium acetate reagent is feasible as an extractant; but of these two, sulfuric acid is preferred. Data obtained by partial extraction methods show that zinc and...

Tide‐producing forces and artesian pressures
William O. George, Frederick E. Romberg

Data are presented to show the relationship of changes in gravity and fluctuations in artesian pressure, and atmospheric pressure, as shown by simultaneous measurements. Computed tide‐producing forces are also shown. The curves are generally conformable....
Nitrate in the ground water of Texas
William O. George, Warren W. Hastings
1951, Eos, Transactions, American Geophysical Union (32) 450-456
Ground water in many parts of Texas contains nitrate in excess of 20 ppm (parts per million) as NO3. About 3,000 of the 20,000 nitrate determinations made of water from wells in Texas showed more than 20 ppm of nitrate. The public water supplies of 27 Texas towns and cities contained more than 50 ppm of nitrate. Recent medical research indicates that methemoglobinemia or infant cyanosis (“blue babies”) may be caused...
Magnetic anomalies at high altitudes
Isadore Zietz, Roland G. Henderson
1951, Eos, Transactions, American Geophysical Union (32) 397-404
To investigate the effect of anomalies in the Earth's magnetic field at high altitudes, aeromagnetic maps of two representative areas showing isanomalic curves for total intensity are projected to levels of 10 and 20 miles above the surface of a plane Earth. The projections are accomplished by numerical computations and by use of a magnetic‐field projecting machine at the Naval...
Metamorphic and igneous rocks of the merrimac area, Plumas National Forest, California
A. Hietanen
1951, Geological Society of America Bulletin (62) 565-608
The pre-granitic rocks of an area in the northern Sierra Nevada consist of metamorphosed sedimentary and volcanic series ranging in age from Carboniferous to Jurassic. Synkinematic ultrabasic intrusives, now serpentines, cut these rocks concordantly and discordantly.Magmatic series ranging from basalt to dacite and soda-rhyolite occur together with the normal basalt-rhyolite...

Iron formation and associated rocks in the Iron River district, Michigan
Harold L. James
1951, Geological Society of America Bulletin (62) 251-266
The iron formation of the Iron River district is part of a Precambrian sequence of strata characterized by a high iron content and varied mineralogy. The iron formation, where unoxidized, consists largely of interlaminated chert and siderite. It is underlain by a graphitic slate containing about 20 per cent iron...
