Extraction and concentration of organic solutes from water
Marvin C. Goldberg, Lewis L. DeLong, Mark Sinclair
1973, Analytical Chemistry (45) 89-93
A continuous extraction apparatus is described. It extracts and simultaneously concentrates organic solutes from water. Any immiscible solvent can be used in this apparatus if the solute will partition between the solvent and water. A concentration factor of up to 105 is obtained with this technique. The dipole moment difference...
U-Th-Pb measurements of Luna 20 soil
M. Tatsumoto
1973, Geochimica et Cosmochimica Acta (37) 1079-1086
The concentrations of uranium, thorium and lead and the lead isotopic composition of Luna 20 soil were determined. The data indicate that the Luna 20 soil is mainly a mixture of highland anorthosites and low-K basalt, but little KREEP basalt. The U-Th-Pb systematics...
Tertiary plate tectonics and high-pressure metamorphism in New Caledonia
R.N. Brothers, M.C. Blake Jr.
1973, Tectonophysics (17) 337-358
The sialic basement of New Caledonia is a Permian-Jurassic greywacke sequence which was folded and metamorphosed to prehnite-pumpellyite or low-grade greenschist facies by the Late Jurassic. Succeeding Cretaceous-Eocene sediments unconformably overlie this basement and extend outwards onto oceanic crust. Tertiary tectonism occurred in three distinct phases.1. During the...

Y.K. Kharaka, F.A.F. Berry, I. Friedman
1973, Geochimica et Cosmochimica Acta (37) 1899-1908
Deuterium and O18 analyses were made on 25 formation-water samples from Miocene (Temblor Formation) and Eocene (McAdams Formation) reservoir rocks at Kettleman North Dome oil field, California, and on three surface water samples from Reef Ridge located about three miles to the west of the field. The δO18 values obtained generally increase with...
Ultrafiltration by a compacted clay membrane-I. Oxygen and hydrogen isotopic fractionation
T.B. Coplen, B.B. Hanshaw
1973, Geochimica et Cosmochimica Acta (37) 2295-2310
Laboratory experiments were carried out to determine the magnitude of the isotopic fractionation of distilled water and of 0.01 N NaCl forced to flow at ambient temperature under a hydraulic pressure drop of 100 bars across a montmorillonite disc compacted to a porosity...

Biochemical monitoring of water after the Cannikin event, Amchitka Island, Alaska, August 1973
Wilbur C. Ballance
1973, Report
Radiochemical data from the Amchitka Island study area were obtained from water samples collected by the U.S. Geological Survey during August 1973. Tritium determinations were made on 86 samples collected and gross alpha and gross beta/gamma determinations were made on 38 samples. The range of data for these samples was...

Snowy owl predation on lapland longspur nestlings recorded on film
T. W. Custer
1973, The Auk (90) 433-435
During the summer of 1971 I investigated the breeding biology of the Lapland Longspur, Calcarius lapponicus, near Barrow, Alaska. To obtain data on incubation and feeding patterns of nesting longspurs, time-lapse cameras (Minolta Autopak-8 D6 super-8 movie cameras equipped with an Intervalometer-P time-lapse device) were positioned at several nests throughout...
18O 16O ratios in cherts associated with the saline lake deposits of East Africa
J. R. O’Neil, R. L. Hay
1973, Earth and Planetary Science Letters (19) 257-266
The cherts formed from sodium silicate precursors in East African saline, alkaline lakes have δ18O values ranging from 31.1 to 44.1. The δ18O values correlate in general with lake salinities as inferred from geologic evidence, indicating that most chert was formed...
Paleomagnetism of some Precambrian basaltic flows and red beds, Eastern Grand Canyon, Arizona
D. P. Elston, Scott G. Robert
1973, Earth and Planetary Science Letters (18) 253-265
Lava flows and red sandstone beds near the middle of the Upper Precambrian Grand Canyon Series exhibit stable remanent magnetization. The beds are about 1000 m stratigraphically above rocks of the Grand Canyon Series for which paleomagnetic poles have been reported. All...
Galerkin finite-element simulation of a geothermal reservoir
J.W. Mercer Jr., G.F. Pinder
1973, Geothermics (2) 81-89
The equations describing fluid flow and energy transport in a porous medium can be used to formulate a mathematical model capable of simulating the transient response of a hot-water geothermal reservoir. The resulting equations can be solved accurately and efficiently using a numerical...
The sorption of silver by poorly crystallized manganese oxides
B.J. Anderson, E. A. Jenne, T. T. Chao
1973, Geochimica et Cosmochimica Acta (37) 611-622
The sorption of silver by poorly crystallized manganese oxides was studied using synthesized samples of three members of the manganous manganite (birnessite) group, of different chemical composition and crystallinity, and a poorly organized γ-MnO2. All four oxides sorbed significant quantities of silver. The manganous manganites showed the greatest sorption (up...

P. Toulmin III, A. K. Baird, B. C. Clark, Klaus Keil, H. J. Rose Jr.
1973, Icarus (20) 153-178
The inorganic chemical investigation added in August 1972 to the Viking Lander scientific package will utilize an energy-dispersive X-ray fluorescence spectrometer in which four sealed, gas-filled proportional counters will detect X-rays emitted from samples of the Martian surface materials irradiated by X-rays from radioisotope sources (55Fe and 109Cd). The output...
Radial particle-size segregation during packing of particulates into cylindrical containers
C.D. Ripple, R.V. James, J. Rubin
1973, Powder Technology (8) 165-175
In a series of experiments, soil materials were placed in long cylindrical containers, using various packing procedures. Soil columns produced by deposition and simultaneous vibratory compaction were dense and axially uniform, but showed significant radial segregation of particle sizes. Similar results were obtained with deposition and simultaneous impact-type compaction when...
Effect of sea water interaction on strontium isotope composition of deep-sea basalts
Dasch E. Julius, C. E. Hedge, J. Dymond
1973, Earth and Planetary Science Letters (19) 177-183
Analyses of rim-to-interior samples of fresh tholeiitic pillow basalts, deuterically altered holocrystalline basalts, and older, weathered tholeiitic basalts from the deep sea indicate that 87Sr/86Sr ratios of the older basalts are raised by low temperature interaction with strontium dissolved in sea water. 87Sr/86Sr correlates...
Endrin uptake and release by fingerling channel catfish (Ictalurus punctatus)
R.L. Argyle, G.C. Williams, H.K. Dupree
1973, Journal of the Fisheries Research Board of Canada (30) 1743-1744
Fingerling channel catfish (Ictalurus punctatus) offered diets containing 0.04–4.0 μg endrin/g food (dry weight) rapidly accumulated the pesticide. Amounts in the tissues were directly proportional to amounts in the food. Dietary endrin had no measurable effect on growth or mortality. After endrin was withdrawn from the diet, it rapidly disappeared and...
