An all-season trap for downstream-migrating fish and other aquatic organisms
Alberton McLain, Patrick J. Manion
1967, Progressive Fish-Culturist (29) 114-117
AN INVESTIGATION OF THE LARVAL STAGES OF THE SEA LAMPREY (Petromyzon marinus), which started in 1960, required a trap that could capture lamprey larvae moving downstream, and that would operate efficiently throughout the year. Sub zero temperatures in the winter and flooding during the spring were the most critical operational...
U.S. Geological Survey silicate rock standards
F.J. Flanagan
1967, Geochimica et Cosmochimica Acta (31) 289-308
The U.S. Geological Survey has processed six silicate rocks to provide new reference samples to supplement G-1 and W-1. Complete conventional, rapid rock, and spectrochemical analyses by the U.S. Geological Survey are reported for a granite (replacement for G-1), a granodiorite, an andesite,...
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...
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...
Precision measurement of lead isotopes ratios: preliminary analyses from the U.S. mine, Bingham Canyon, Utah
J. S. Stacey, W. J. Moore, R.D. Rubright
1967, Earth and Planetary Science Letters (2) 489-499
A gas-source mass spectrometer has been constructed for the precise measurement of lead isotope ratios. Sixteen analyses on 4 different preparations of the same galena made over a period of 2 months gave 95% confidence limits (per analysis) of 206Pb/204Pb= 0.080%, 207Pb/206Pb= 0.042%and208Pb/206Pb=...
Field Methods for the Study of Slope and Fluvial Processes
Luna Bergere Leopold, editor(s)
1967, Revue de Géomorphologie Dynamique (17) 147-187
In Belgium during the summer of 1966 the Commission on Slopes and the Commission on Applied Geomorphology of the International Geographical Union sponsored a joint symposium, with field excursions, and meetings of the two commissions. As a result of the conference and associated discussions, the participants expressed the view that...

The occurrence and origin of lamellar troilite in iron meteorites
R. Brett, E.P. Henderson
1967, Geochimica et Cosmochimica Acta (31) 721-730
A number of iron meteorites contain elongated inclusions consisting predominantly of troilite, which have been termed Reichenbach lamellae. Two types of inclusions exist, the first up to 6 cm long and 0·2 mm wide, the second up to 2 cm long and 3 mm wide. The first type contains troilite...

Devonian of the Appalachian Basin, United States
William A. Oliver, Wallace De Witt, John M. Dennison, D.M. Hoskins, John W. Huddle
1967, Conference Paper, International symposium on the Devonian system
Although Devonian rocks in the Appalachians have been studied for more than 150 years, they are poorly known in most of the area. The nearly complete Devonian sequence in New York has been established as the North American standard of reference. The structural belt that includes unmetamorphosed Devonian geosynclinal...
Succession of rugose coral faunas in the Lower and Middle Devonian of eastern North America
William Albert Oliver Jr.
1967, Conference Paper, International symposium on the Devonian system
Rocks of Early Devonian age are widely but sporadically distributed in the eastern half of North America and coral studies are based on a very incomplete record. Middle Devonian rocks are thicker and cover a greater area. Both Early and Middle Devonian corals are more similar to western European species...
Major land uses in the United States
Francis J. Marschner, James R. Anderson
1967, Report, The national atlas of the United States of America
This is a polygon coverage of major land uses in the United States. The source of the coverage is the map of major land uses in the National Atlas, pages 158-159, which was adapted from U.S. Department of Agriculture, "Major Land Uses in the United States," by Francis...
Cohenite: Its occurrence and a proposed origin
R. Brett
1967, Geochimica et Cosmochimica Acta (31) 143-159
Cohenite is found almost exclusively in meteorites containing from 6 to 8 wt.% Ni. On the basis of phase diagrams and kinetic data it is proposed that cohenite cannot form in meteorites having more than 8 wt.% Ni and that any cohenite which formed in meteorites having Ni content lower...
Complexometric determination of gallium with calcein blue as indicator
H.N. Elsheimer
1967, Talanta (14) 97-102
A metalfluorechromic indicator, Calcein Blue, has been used for the back-titration of milligram amounts of EDTA in presence of gallium complexes. The indicator was used in conjunction with an ultraviolet titration assembly equipped with a cadmium sulphide detector cell and a microammeter for enhanced end-point detection....
Geomagnetic polarity epochs: new data from Olduvai Gorge, Tanganyika
C. S. Grommé, R. L. Hay
1967, Earth and Planetary Science Letters (2) 111-115
The lower lava flow of Bed I in Olduvai Gorge, Tanganyika, carries natural remanent magnetization (NRM) having normal polarity. Thermal demagnetization experiments demonstrate the stability of this NRM. Thus the Olduvai geomagnetic polarity event, which was originally named from the upper lava...

Loss of halogens from crystallized and glassy silicic volcanic rocks
D. C. Noble, V. C. Smith, L. C. Peck
1967, Geochimica et Cosmochimica Acta (31) 215-223
One hundred and sixty-four F and Cl analyses of silicic welded tuffs and lavas and glass separates are presented. Comparison of the F and Cl contents of crystallized rocks with those of nonhydrated glass and hydrated glassy rocks from the same rock units shows that most of the halogens originally...
The fractionation of nickel between olivine and augite as a geothermometer
T.A. Hakli, T. L. Wright
1967, Geochimica et Cosmochimica Acta (31) 877-884
The coexisting olivine, clinopyroxene and glass of five samples collected from the Makaopuhi lava lake in Hawaii, at temperatures ranging from 1050 to 1160°C were analysed for nickel with an electron probe microanalyser. The results strongly suggest that the distribution of nickel between these three phase pairs well obeys the...
The effect of the lamprey larvicide, 3-trifluormethyl-4-nitrophenol, on selected aquatic invertebrates
Allen J. Smith
1967, Transactions of the American Fisheries Society (96) 410-413
The chemical compound 3-trifluoromethyl-4-nitrophenol (TFM) is used to control the sea lamprey (Petromyzon marinus) in the upper Great Lakes. It is introduced into streams in which sea lampreys have spawned, to kill the larvae. These 'treatments' are carried out at intervals shorter than the larval phase of the sea lamprey's...
