A set of four standard glasses has been prepared which have been doped with 61 different elements at the 500-, 50-, 1-, and 0.02-ppm level. The concentrations of lead, uranium, thorium, and thallium have been determined by isotope dilution mass spectrometry at a number of points in each of the...
Geologic implications of the Apollo 14 Fra Mauro breccias and comparison with ejecta from the Ries Crater, Germany
E. C. T. Chao
1973, Journal of Research of the U.S. Geological Survey (1) 1-18
On the basis of petrographic and laboratory and active seismic data for the Fra Mauro breccias, and by comparison with the nature and distribution of the ejecta from the Ries crater, Germany, some tentative conclusions regarding the geologic significance of the Fra Mauro Formation on the moon can be drawn. The Fra Mauro Formation, as...

Donald C. Ross, Carl M. Wentworth, Edwin D. McKee
1973, Journal of Research of the U.S. Geological Survey (1) 45-52
Upper Cretaceous mafic conglomerate and quartz-plagioclase arkose that crop out on the southwest side of the San Andreas fault near Gualala, Calif., may have been eroded from a gabbroic terrane that now lies about 350 miles to the southeast, on the opposite side of the San Andreas fault. The plagioclase arkose near Gualala contains little...
River channel change with time : An example
Luna Bergere Leopold
1973, Geological Society of America Bulletin (84) 1845-1860
Monumented channel cross sections were resurveyed over a period of 20 yrs (1953 to 1972) to determine the amount and kind of change of channel area and position on a 3.7-sq-mi basin, Watts Branch near Rockville, Maryland. For the first 12 yrs, the channel progressively but slowly became smaller as...
The role of the Bureau of Sport Fisheries and Wildlife in the Great Lakes
F. Eugene Hester
1973, Conference Paper, Proceedings of the First Federal Conference on the Great Lakes
Ecological blunders of man, such as timber exploitation, draining of wetlands, construction of canals and dams, and pollution have been mainly responsible for serious environmental degradation and catastrophic losses of fish and wildlife values in the Great Lakes Basin. Consequently, the major emphasis of the Bureau of Sport Fisheries and...
Federal Great Lakes fishery research objectives, priorities, and projects
Howard D. Tait
1973, Conference Paper, Proceedings of the First Federal Conference on the Great Lakes
Fishery productivity of the Great Lakes has declined drastically since settlement of the area. Premium quality fishes of the Great Lakes such as whitefish, lake trout, and walleyes have been replaced by less desired species. This change is attributed to selective overfishing, pollution, and the extreme instability of fish populations....
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...

Comparison of the magnetic properties of glass from Luna 20 with similar properties of glass from the Apollo missions
F. E. Senftle, A. N. Thorpe, C.C. Alexander, C.L. Briggs
1973, Geochimica et Cosmochimica Acta (37) 1053-1062
Magnetic susceptibility measurements have been made on four glass spherules and fragments from the Luna 20 fines; two at 300°K and two from 300°K to 4°K. From these data the magnetic susceptibility extrapolated to infinite field, the magnetization at low fields and also...
Coexisting cummingtonite and aluminous hornblende from garnet amphibolite, Boehls Butte area, Idaho, USA
A. Hietanen
1973, LITHOS (6) 261-264
Electron microprobe analyses of green hornblende and coexisting cummingtonite from garnet amphibolite show identical Fe/Mg ratios ( = 0.9). Cummingtonite is iron-magnesium silicate with very little calcium and aluminum and practically no alkalies. In contrast, the hornblende has 1.5 tetrahedral Al, 0.9 octahedral...
Mariner 9-Image processing and products

1973, Icarus (18) 75-101
The purpose of this paper is to describe the system for the display, processing, and production of image-data products created to support the Mariner 9 Television Experiment. Of necessity, the system was large in order to respond to the needs of a large team of scientists with a broad scope...
Production of superheated steam from vapor-dominated geothermal reservoirs
A.H. Truesdell, D. E. White
1973, Geothermics (2) 154-173
Vapor-dominated geothermal systems such as Larderello, Italy, The Geysers, California, and Matsukawa, Japan yield dry or superheated steam when exploited. Models for these systems are examined along with production data and the thermodynamic properties of water, steam and rock. It is concluded that...
Statistical recognition of late Cretaceous cyclic sedimentation by means of calcareous nannofossil population studies
I.R. Mayers, T.R. Worsley
1973, Palaeogeography, Palaeoclimatology, Palaeoecology (13) 81-90
The relative abundance of calcareous nannofossil taxa in a sequence of samples collected from a continuous Upper Maastrichtian section in Alabama has been analyzed using statistical techniques. Results indicate that an increase of arbitrarily chosen long-ranging forms can be represented by a slowly...
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...
Uranium concentration and distribution in six peridotite inclusions of probable mantle origin
E.L. Haines, R. E. Zartman
1973, Earth and Planetary Science Letters (20) 45-53
Fission-track activation was used to investigate uranium concentration and distribution in peridotite inclusions in alkali basalt from six localities. Whole-rock uranium concentrations range from 24 to 82 ng/g (1ng= 10−9g). Most of the uranium is uniformly distributed in the major silicate phases...
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...

Application of theory and research in fishery management of the Laurentian Great Lakes
Stanford H. Smith
1973, Transactions of the American Fisheries Society (102) 156-163
The Great Lakes have a high potential for the conduct of research and useful application of research findings, but the history of the Great Lakes indicates that extensive research and intensive management have failed to prevent deterioration of the fisheries. At times the research was not done before a loss...
