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...
Isotopic composition of oil-field brines from Kettleman North Dome, California, and their geologic implications
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...
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...
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...
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...
Lead concentration and isotopic composition in five peridotite inclusions of probable mantle origin
R. E. Zartman, F. Tera
1973, Earth and Planetary Science Letters (20) 54-66
The lead content of five whole-rock peridotite inclusions (four lherzolites and one harzburgite) in alkali basalt ranges from 82 to 570 ppb (parts per billion). Approximately 30–60 ppb of this amount can be accounted for by analyzed major silicate minerals (olivine ≤...
Evaporite deposits of Bogota area, Cordillera Oriental, Colombia
Donald H. McLaughlin Jr.
1972, American Association of Petroleum Geologists Bulletin (56) 2240-2259
Four evaporite-bearing stratigraphic zones are known in Cretaceous strata of the Cordillera Oriental of Colombia north and east of Bogota. The easternmost and oldest zone is probably of Berriasian to Valanginian age. The next oldest is probably late Barremian to early Aptian in age. The third appears to be Aptian....

Frederick J. Doyle
1972, Book chapter, Apollo 15 preliminary science report (NASA SP-289)
The three cameras—stellar, mapping, and panoramic—together with the laser altimeter, all included in the scientific instrument module (SIM) bay, represent an integrated photogrammatric system with extraordinary potential for extending knowledge of the lunar figure, surface configuration, and geological structure....
Photogeology: Part B: Cayley Formation interpreted as basin ejecta
R. E. Eggleton, G. G. Schaber
1972, Book chapter, Apollo 16 preliminary science report (NASA SP 315)
The discovery that samples returned from the Cayley Formation at the Apollo 16 landing site consist mainly of nonvolcanic breccias (secs. 6 and 7 of this report) suggests that the hypothesis in which light plains-forming materials may be ejecta from multi-ring basins should be reevaluated (refs 29-15 to 29-17). Improved...
Photogeology: Part D: Descartes highlands: possible analogs around the Orientale Basin
Carroll Ann Hodges
1972, Book chapter, Apollo 16 preliminary science report (NASA SP 315)
The Descartes highlands are adjacent to the terra plain on which the Apollo 16 lunar module landed (fig. 29-13). A variety of volcanic origins was proposed for the highlands before the mission (refs. 29-4, 29-21, and 29-35 to 29-37), but the returned samples of the area consist almost exclusively of...

An Analysis of the Population Dynamics of Selected Avian Species--With Special References to Changes During the Modern Pesticide Era
Charles J. Henny
1972, Wildlife Research Report No. 1
The impact of pesticides on the mortality rates and recruitment rates of nongame birds during the last 25 years was evaluated by studying the population dynamics of 16 species. A mathematical model showing the relations between population parameters that yielded stable populations was developed. The information needed for the model...
Food resources of the California condor
S.R. Wilbur
1972, Report
Conclusions and Recommendations: Although much of the above information is imprecise and inconclusive, it is evident that the condors foraging habitat is diminishing. Food supply probably is still adequate for free-ranging nonbreeding birds, but could become limited if current land use trends continue. Congregating condors on fewer...
Influence of grounding ice on the Arctic shelf of Alaska
E. Reimnitz, P. Barnes, T. Forgatsch, C. Rodeick
1972, Marine Geology (13) 323-334
Alaska's Beaufort Sea shelf is characterized by small-scale relief with an average amplitude of 1–2 m and wavelength of 50–100 m. Diving observations confirm that much of the bottom roughness reflects the action of grounded ice. Except for areas in the shadow of...

Saul E. Rantz
1972, Open-File Report 72-462
This report presents a summary view of the water-supply situation in the nine counties that comprise the San Francisco Bay region, California, and thereby provides water data, based on 1970 conditions, that are needed for regional planning. For the purpose of this study the nine-county region has been divided into...
Accelerations near faults that have moved during moderate-sized earthquakes
David M. Boore, Robert A. Page
1972, Open-File Report 72-43
Peak ground accelerations recently recorded within 10-15 km of faulting during moderate-sized earthquakes (m = 4 to 6) are significantly underestimated by many, if not most, of the empirical acceleration-distance relations commonly used in seismic engineering. The recent data show a rapid decrease of peak acceleration with increasing distances (at...
