Tide‐producing forces and artesian pressures
William O. George, Frederick E. Romberg
1951, Eos, Transactions, American Geophysical Union (32) 369-371
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...
Stratigraphy and structure of the southern foothills section between the Etivluk and Kiligwa Rivers
Irvin L. Tailleur, Bion H. Kent
1951, Geological Investigations, Naval Petroleum Reserve No. 4, Alaska 43
The part of the Southern Foothill section, Arctic foothills province, that lies beteween the Etivluk and Kiligwa Rivers was investigated by Navy Oil Unit party 6 during the 1950 field season, A belt about 16 miles wide and 60 miles long (approximately 800 square miles) was mapped in considerable detail...

Stabilization of some rockslides in Grainger County, Tennessee
Robert A. Laurence
1951, Economic Geology (46) 329-336
Slides in dipping Cambrian sandstone, resulting from highway relocation along Norris Reservoir, have been stabilized by the use of steel dowels and concrete anchor blocks. Geologic conditions favored this type of treatment, as sliding took place in thin shales between thick sandstone beds....

William W. Patton Jr., A. Samuel Keller
1951, Geological Investigations, Naval Petroleum Reserve No. 4, Alaska 42
Structural and stratigraphic studies of tha rocks in the Siksikpuk and Nanushuk Rivers area were conducted by Navy Oil Unit party 2 during the summer field season of 1950. The field party consisted of two geologists, two field assistants, a cook, and a weasel mechanic. Three weasels were used for...

Discussion of “pedological relations of infiltration phenomena”
W. C. Rasmussen, W. O. Smith
1951, Eos, Transactions, American Geophysical Union (32) 282-283
Smith provides an illuminating consideration of infiltration through soil in relation to the structure and texture of the soil its moisture content, and the variation of infiltration for A, B, and C soil zones. The organic nature of soil might also be stressed. Rotting rootlets provide passageways for water in...

Uranium resources in the Silver Reef (Harrisburg) District, Washington County, Utah
Frederick Stugard Jr.
1951, Trace Elements Memorandum 214
The Silver Reef district is near Leeds, about 16 miles north of St. George, Utah. The major structural feature of the district is the Virgin anticline, a fold extending southwestward toward St 0 George. The anticline has been breached by erosion, and sandstone hogbacks or “reefs” are carved from the Shinarump conglomerate and sandstone...
Preliminary statement of the analyses of ground water from the Morrison Formation, southwestern Colorado and southeastern Utah
