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...
Age of Kōko Seamount, Emperor Seamount chain
David A. Clague, G. Brent Dalrymple
1973, Earth and Planetary Science Letters (17) 411-415
K—Ar ages obtained by the conventional isotope-dilution and the 40Ar/39Ar techniques on two sanidine trachytes, four basalts, and a phonolite dredged from the top of Kōko Seamount, 300 km north of the Hawaiian-Emperor bend, show that the seamount is 46.4 ± 1.1 my old. These data indicate that the volcanoes in...
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...
Stress changes ahead of an advancing tunnel
J.F. Abel, F. T. Lee
1973, International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts (10) 673-697
Instrumentation placed ahead of three model tunnels in the laboratory and ahead of a crosscut driven in a metamorphic rock mass detected stress changes several tunnel diameters ahead of the tunnel face. Stress changes were detected 4 diameters ahead of a model tunnel drilled into nearly elastic acrylic, 2·50 diameters...
Thermal conductivity of carbonate rocks
J. Thomas Jr., R.R. Frost, R.D. Harvey
1973, Engineering Geology (7) 3-12
The thermal conductivities of several well-defined carbonate rocks were determined near 40°C. Values range from 1.2 W m−1C−1 for a highly porous chalk to 5.1 W m−1C−1 for a dolomite. The thermal conductivity of magnesite (5.0) is at the high end of the range, and that for Iceland Spar Calcite (3.2) is near the...
K, Rb, Sr and 87Sr 86Sr in rocks from the Mid-Indian Oceanic Ridge
K.V. Subbarao, C. E. Hedge
1973, Earth and Planetary Science Letters (18) 223-228
The 87Sr/86Sr ratios of Mid-Indian Oceanic Ridge (MIOR) basalts are nearly identical (0.7032 to 0.7035), with the exception of one more highly radiogenic sample (0.7043). These values are consistently higher than the strontium isotopic ratios of the ridge basalts from Atlantic and...
Imaging characteristics of photogrammetric camera systems
R. Welch, J. Halliday
1973, Photogrammetria (29) 1-43
In view of the current interest in high-altitude and space photographic systems for photogrammetric mapping, the United States Geological Survey (U.S.G.S.) undertook a comprehensive research project designed to explore the practical aspects of applying the latest image quality evaluation techniques to the analysis of such systems. The project had two...
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...
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...
Ultrafiltration by a compacted clay membrane-II. Sodium ion exclusion at various ionic strengths
B.B. Hanshaw, T.B. Coplen
1973, Geochimica et Cosmochimica Acta (37) 2311-2327
Several recent laboratory studies and field investigations have indicated that shales and compacted clay minerals behave as semipermeable membranes. One of the properties of semipermeable membranes is to retard or prevent the passage of charged ionic species through the membrane pores while allowing relatively free movement of uncharged species. This...
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...
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...

Constitutive relations associated with the Mott-Smith distribution function
M. Nathenson, D. Baganoff
1973, Physics of Fluids (16) 2110-2115
It is shown that the distribution function assumed by Mott-Smith determines a unique relation between heat flux, stress, and fluid velocity given by q = (3/2)τu, i.e., it provides a constitutive relation for heat flux, and it also determines a simple expression for this ratio of third-order central moments Q...
