K Ar and Rb Sr measurements on P-207, the U.S.G.S. interlaboratory standard muscovite
M. A. Lanphere, G. B. Dalrymple
1967, Geochimica et Cosmochimica Acta (31) 1091-1094
Potassium-argon analyses of P-207 in twenty-four laboratories and rubidium-strontium analyses in ten laboratories indicate that for material of this typo the average interlaboratory precision for KAr ages is 2.6% and for RbSr ages is 3.4%, and the average intralaboratory precision for KAr ages is 1.6% and for RbSr ages is...
Pliocene geomagnetic polarity epochs
G. B. Dalrymple, A. Cox, Richard R. Doell, C. S. Grommé
1967, Earth and Planetary Science Letters (2) 163-173
A paleomagnetic and K-Ar dating study of 44 upper Miocene and Pliocene volcanic units from the western United States suggests that the frequency of reversals of the earth's magnetic field during Pliocene time may have been comparable with that of the...
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...
Ground-water research in the U.S.A.
C. L. McGuinness
1967, Earth-Science Reviews (3) 181-202
Ground-water reservoirs and the overlying unsaturated zone-collectively, the "subsurface"-have an enormous capacity to supply water to wells and useful plants, to store water to meet future needs for the same purposes, and, under suitable precautions, to accept wastes. This capacity can be exploited on a maximum scale, however, only on...
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...
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...

Hydrology of the Valley-fill and carbonate-rock reservoirs, Pahrump Valley, Nevada-California
Glenn T. Malmberg
1967, Water Supply Paper 1832
This is the second appraisal of the water supply of Pahrump Valley, made 15 years after the first cooperative study. In the first report the average recharge was estimated to be 23,000 acre-feet per year, only 1,000 acre-feet more than the estimate made in this report. All this recharge was...
Base surge in recent volcanic eruptions
J.G. Moore
1967, Bulletin Volcanologique (30) 337-363
A base surge, first identified at the Bikini thermonuclear undersea explosion, is a ring-shaped basal cloud that sweeps outward as a density flow from the base of a vertical explosion column. Base surges are also common in shallow underground test explosions and are formed by expanding gases which first vent...

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...
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...
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%...
