Yakima basalt of the Tieton River area, south-central Washington
Donald A. Swanson
1967, Geological Society of America Bulletin (78) 1077-1110
Up to 1700 feet of the upper Miocene-lower Pliocene Yakima Basalt of the Columbia River Group underlie much of the eastern flank of the Cascade Range in the Tieton River area, Yakima County, Washington. Local prebasalt relief was more than 1700 feet, so thicknesses of each of the 15...
Morphological abnormalities among lampreys
Patrick J. Manion
1967, Copeia (1967) 680-681
The experimental control of the sea lamprey (Petromyzon marinus) in the Great Lakes has required the collection of thousands of lampreys. Representatives of each life stage of the four species of the Lake Superior basin were examined for structural abnormalities. The most common aberration was the presence of...
A seventeenth century mandibular tumor in a North American Indian
E.E. Kelln, E.V. McMichael, B. Zimmermann
1967, Oral Surgery, Oral Medicine, Oral Pathology (23) 78-81
The oldest tumor so far recorded is believed to have been a hemangioma. It occurred in a bone of a dinosaur’s tail1 and thus considerably antedates the historical period. The oldest known human tumor is much younger, dating back only to the middle of the third century after Christ.1 It...
Returns of hatchery-reared lake trout in southern Lake Superior, 1955-62
Richard L. Pycha, George R. King
1967, Journal of the Fisheries Research Board of Canada (24) 281-298
Experimental plantings of fin-clipped lake trout (Salvelinus namaycush) of various ages have been made in southern Lake Superior since 1952. The catch of planted lake trout by the commercial fishery was used to measure the success of stocking. Estimates of total returns were based on samples of 8.2 to 21.2%...
Diatoms as food of larval sea lampreys in a small tributary of northern Lake Michigan
Patrick J. Manion
1967, Transactions of the American Fisheries Society (96) 224-226
The food and food preferences of sea lamprey ammocoetes have not been investigated. The food of the larval American brook lamprey, Lampetra lamottei, in the Great Lakes region consisted mainly of diatoms and desmids according to Creaser and Hann. Schroll discussed the biology of feeding of ammocoetes of Lampetra planeri...
Hydrologic and climatologic data, 1966, Salt Lake County, Utah
A. G. Hely, Reed W. Mower, C. A. Horr
1967, Utah Basic-Data Release 13
An investigation of the water resources of Salt Lake County, Utah, was undertaken by the Water Resources Division of the U.S. Geological Survey in July 1963. This investigation is a cooperative project financed equally by the State of Utah and the Federal Government in accordance with an agreement between the...
Serial publications commonly cited in technical bibliographies of the United States Geological Survey
Water Resources Division, U.S. Geological Survey
1967, Report
This compilation is a listing of the serial publications cited in the following publications of the United States Geological Survey: Geophysical Abstracts, Abstracts of North American Geology, Bibliography of North American Geology, and Bibliography of Hydrology of the United States. A supplement of publications added since the main list was...
The Amazon, measuring a mighty river
Water Resources Division, U.S. Geological Survey
1967, Report
The Amazon, the world's largest river, discharges enough water into the sea each day to provide fresh water to the City of New York for over 9 years. Its flow accounts for about 15 percent of all the fresh water discharged into the oceans by all the rivers of the...
Molecular characteristics versus biological activity
Vernon C. Applegate, Manning A. Smith, Bennett R. Willeford
1967, Chemistry (40) 28-30
The molecular characteristics of mononitrophenols containing halogens not only play a key role in their biological activity but provide a novel example of selective toxicity among vertebrate animals. It has been reported that efforts to control the parasitic sea lamprey in the Great Lakes are directed at present to...
Geomagnetic polarity epochs: Nunivak Island, Alaska
A. Cox, G. B. Dalrymple
1967, Earth and Planetary Science Letters (3) 173-177
New paleomagnetic and potassium-argon dating measurements have been made of basalt flows from Nunivak Island, Alaska, with the following results. (1) The best estimate of the age of the Brunhes/Matuyama polarity epoch boundary is found to be 0.694 m.y. (2) The best...
The Alaska earthquake of 1964
W. R. Hansen
1967, Nature (215) 348-351
Now that the dust has settled it is possible to assess the long term effects of the Alaskan earthquake on March 27, both on the activities of man and on the wild life of the State....
A low pressure investigation of the stability of phlogopite
D. R. Wones
1967, Geochimica et Cosmochimica Acta (31) 2248-2253
Phlogopite reacts to form orthorhombic kalsilite, leucite, forsterite and fluid (H2O) at 1012 ± 7°C, 400 bars pressure, and 905 ± 5°C at 100 bars pressure. The heat of reaction is 39 ± 4 kcal compared to 44 ± 6kcal for the reaction of annite to form orthorhombic kalsilite, leueite, fayalite...
Sediments and fossiliferous rocks from the eastern side of the Tongue of the Ocean, Bahamas
Thomas G. Gibson, John Schlee
1967, Deep-Sea Research and Oceanographic Abstracts (14) 691-694
In August 1966, two dives were made with the deep-diving submersible Alvin along the eastern side of the Tongue of the Ocean to sample the rock and sediment. Physiographically, the area is marked by steep slopes of silty carbonate sediment and precipitous rock cliffs dusted by carbonate debris. Three rocks, obtained from...
On the chemistry of Jupiter's upper atmosphere
W.C. Saslaw, R.L. Wildey
1967, Icarus (7) 85-93
We conduct a first investigation into the ion-molecule chemistry of the upper Jovian atmosphere. Experimental results show that intense ultraviolet radiation reacts with the constituents of the Jovian atmosphere to produce C2H4, C2H6, C3H8, and higher polymers. The general procedure for calculating both equilibrium and nonequilibrium abundances of these products...
87Sr/86Sr ratios in some eugeosynclinal sedimentary rocks and their bearing on the origin of granitic magma in orogenic belts
Z. E. Peterman, C. E. Hedge, R. G. Coleman, P. D. Snavely Jr.
1967, Earth and Planetary Science Letters (2) 433-439
Rb and Sr contents and87Sr/86Sr values were determined for samples of eugeosynclinal sedimentary rocks, mostly graywackes, from Oregon and California. These data are compatible with the theory of anataxis of eugeosynclinal sedimentary rocks in orogenic belts to produce granitic magmas provided...
Theory of friction based on brittle fracture
J.D. Byerlee
1967, Journal of Applied Physics (38) 2928-2934
A theory of friction is presented that may be more applicable to geologic materials than the classic Bowden and Tabor theory. In the model, surfaces touch at the peaks of asperities and sliding occurs when the asperities fail by brittle fracture. The coefficient of friction, μ, was calculated from the strength of asperities of certain ideal shapes; for...
An operational theory of laser-radar selenodesy
R.L. Wildey, R.E. Schlier, J. A. Hull, G. Larson
1967, Icarus (6) 315-347
A theory of the utilization of laser techniques for ranging from the Earth to the Moon for the purpose of providing control points on the lunar surface at which the figure of the Moon is measured to an accuracy at least an order of magnitude better than that of...
