A.H. Truesdell
1974, Earth and Planetary Science Letters (23) 387-396
Studies of the effect of dissolved salts on the oxygen isotope activity ratio of water have been extended to 275°C. Dehydrated salts were added to water of known isotope composition and the solutions were equilibrated with CO2 which was sampled for analysis. For...

E. C. T. Chao, J.A. Minkin, C.L. Thompson
1974, Earth and Planetary Science Letters (23) 413-428
Preliminary petrographic description and mineral composition of four hand samples (77135, 77115, 77075 and 77215) are presented. 77135, 77115, and 77075 all crystallized from fragment-laden melts; they are similar in textures but differ in grain size. 77135 and 77115 are pigeonite feldspathic...

Craters on Earth, Moon, and Mars: Multivariate classification and mode of origin
R.J. Pike
1974, Earth and Planetary Science Letters (22) 245-255
Testing extraterrestrial craters and candidate terrestrial analogs for morphologic similitude is treated as a problem in numerical taxonomy. According to a principal-components solution and a cluster analysis, 402 representative craters on the Earth, the Moon, and Mars divide into two major classes...
Naturally occurring vapor-liquid-solid (VLS) Whisker growth of germanium sulfide
R. B. Finkelman, R.R. Larson, E.J. Dwornik
1974, Journal of Crystal Growth (22) 159-160
The first naturally occurring terrestrial example of vapor-liquid-solid (VLS) growth has been observed in condensates from gases released by burning coal in culm banks. Scanning electron microscopy, X-ray diffraction, and energy dispersive analysis indicate that the crystals consist of elongated rods (≈ 100...
U-Th-Pb and Rb-Sr systematics of Apollo 17 boulder 7 from the North Massif of the Taurus-Littrow Valley
P.D. Nunes, M. Tatsumoto, D.M. Unruh
1974, Earth and Planetary Science Letters (23) 445-452
Portions of highland breccia boulder 7 collected during the Apollo 17 mission were studied using UThPb and RbSr systematics. A RbSr internal isochron age of3.89 ± 0.08b.y. with an initial87Sr/86Sr of0.69926 ± 0.00008 was obtained for...
Social behavior of breeding gadwalls in North Dakota
T.J. Dwyer
1974, The Auk (91) 375-386
Responses of duck pairs encountering other ducks were categorized by McKinney (1965a) as displays, attack, escape and avoidance, sexual pursuit, and sociability. Gadwalls (Anas strepera) show all these responses on the breeding grounds, and characteristic behavior patterns occur depending on the reproductive state of the birds involved. The responses of...
Residues of DDT in lake trout (Salvelinus namaycush) and coho salmon (Oncorhynchus kisutch) from the Great Lakes
Robert E. Reinert, Harold L. Bergman
1974, Journal of the Fisheries Research Board of Canada (31) 191-199
Concentrations of DDT residues were higher in lake trout (Salvelinus namaycush) from southern Lake Michigan in 1966–70 (average 18.1 ppm in fish 558–684 mm long) than in lake trout of the same size-class from Lake Superior in 1968–69 (4.4 ppm), and higher in adult coho salmon (Oncorhynchus kisutch) from Lake Michigan in 1968–71...
Dieldrin and DDT: accumulation from water and food by lake trout (Salvelinus namaycush) in the laboratory
Robert E. Reinert, Linda J. Stone, Harold L. Bergman
1974, Proceedings of the Conference on Great Lakes Research (17) 52-58
In the laboratory we measured the amounts of dieldrin and p,p'DDT accumulated by fish from contaminated water and food to determine how fish from Lake Michigan accumulate high concentrations of these insecticides from an environment where the concentrations in water are generally less than 0.01 ppb. Eight groups of yearling...

Mineral resources of Du Noir Addition, Washakie Wilderness area, Fremont County, Wyoming
Harold J. Prostka, J.C. Antweiler, Carl L. Bieniewski, M. D. Kleinkopf
1974, Open-File Report 74-133
The Du Noir Addition to the Washakie Wilderness area consists of 34,200 acres (13,840 hectares) of scenic mountainous terrain that adjoins the Teton Wilderness and Washakie Wilderness areas. The area was studied in 1973 by the U.S. Geological Survey and U.S. Bureau of Mines to evaluate its mineral, fuel, and...
Short-term fate of dietary dieldrin in the digestive tract of juvenile lake trout (Salvelinus namaycush)
Donald J. Stewart, Roy A. Stein
1974, Bulletin of Environmental Contamination and Toxicology (11) 563-566
Short-term fate of dietary dieldrin in the digestive tract of fishes is poorly known. Studies of the uptake, distribution, and elimination of chlorinated hydrocarbons have suggested that uptake or degradation is rapid in the intestine (GROSS 1969; MACEK et al. 1970; GRZENDA et al. 1970, 1971). The present study was...

Nitrogen and phosphorus balance of grass carp, Ctenopharyngodon idella, fed elodea, Egeria denea
J.G. Stanley
1974, Transactions of the American Fisheries Society (103) 587-592
The herbivorous grass carp fed winter elodea exhibited a negative nitrogen balance in metabolism, suggesting that food having a higher protein content would be required for normal growth. About a third of the phosphorus contained in food was retained; hence, a combination of aquatic plants and grass carp might afford...
Lunar crater depths from orbiter IV long-focus photographs
D.W.G. Arthur
1974, Icarus (23) 116-133
The paper presents method and results for the determination of the depths of more than 1900 small lunar craters from measures of shadows on the long-focus pictures obtained by Lunar Orbiter IV. The method for converting the measured shadow length into the true...

R.J. Pike
1974, Earth and Planetary Science Letters (23) 265-271
Amendments to a quantitative scheme developed by T.R. McGetchin et al. (1973) for predicting the distribution of ejecta from lunar basins yield substantially thicker estimates of ejecta, deposited at the basin rim-crest and at varying ranges byond, than does the original model....

L. P. Greenland, D. Gottfried, R.I. Tilling
1974, Chemical Geology (14) 117-122
Neutron-activation determinations of Ir in rocks of the Southern California and Boulder (Montana) batholiths show that the Ir content is low and variable in both batholiths, extending over 1 to 2 orders of magnitude and having a combined median of 0.006 ppb...
Fish sporozoa: Extraction of antigens from Myxosoma cerebralis spores which mimic tissue antigens of rainbow trout (Salmo gairdneri)
G.B. Pauley
1974, Journal of the Fisheries Research Board of Canada (31) 1481-1484
This is the first report of an antigenic preparation from the spore stage of any histozoic sporozoan parasite. The method for successful extraction of the antigens is presented. This antigenic preparation is active in rabbits, but not salmonid fish. The detection of asymptomatic carrier fish using the spore antigens was...
