U.S. Geological Survey silicate rock standards
F.J. Flanagan
1967, Geochimica et Cosmochimica Acta (31) 289-308
The U.S. Geological Survey has processed six silicate rocks to provide new reference samples to supplement G-1 and W-1. Complete conventional, rapid rock, and spectrochemical analyses by the U.S. Geological Survey are reported for a granite (replacement for G-1), a granodiorite, an andesite,...
Potassium-argon ages of recent rhyolites of the Mono and Inyo craters, California
G. Brent Dalrymple
1967, Earth and Planetary Science Letters (3) 289-298
Twenty-two KAr ages were determined for sanidine samples from 10 rhyolite domes of the Mono and Inyo Craters to test the applicability of KAr dating to volcanic rocks of Recent age. Comparison of the results with ‘blank’ and dosed analyses shows...
Loss of halogens from crystallized and glassy silicic volcanic rocks
D. C. Noble, V. C. Smith, L. C. Peck
1967, Geochimica et Cosmochimica Acta (31) 215-223
One hundred and sixty-four F and Cl analyses of silicic welded tuffs and lavas and glass separates are presented. Comparison of the F and Cl contents of crystallized rocks with those of nonhydrated glass and hydrated glassy rocks from the same rock units shows that most of the halogens originally...
Ground-water research in the U.S.A.
C. L. McGuinness
1967, Earth-Science Reviews (3) 181-202
Ground-water reservoirs and the overlying unsaturated zone-collectively, the "subsurface"-have an enormous capacity to supply water to wells and useful plants, to store water to meet future needs for the same purposes, and, under suitable precautions, to accept wastes. This capacity can be exploited on a maximum scale, however, only on...
Geochemical evidence of present-day serpentinization
I. Barnes, Valmore C. LaMarche Jr., G. Himmelberg
1967, Science (156) 830-832
Ultrabasic (pH > 11) water issues from some fresh ultramafic bodies. The properties of the ultrabasic solutions are believed to be due to current reactions yielding serpentine from primary olivines and pyroxenes. The low concentrations of divalent iron, divalent magnesium, and dissolved silica from the serpentinization require an increase in...
Base surge in recent volcanic eruptions
J.G. Moore
1967, Bulletin Volcanologique (30) 337-363
A base surge, first identified at the Bikini thermonuclear undersea explosion, is a ring-shaped basal cloud that sweeps outward as a density flow from the base of a vertical explosion column. Base surges are also common in shallow underground test explosions and are formed by expanding gases which first vent...
Borate mineral assemblages in the system Na2O-CaO-MgO-B2O3-H2O
C. L. Christ, A.H. Truesdell, Richard C. Erd
1967, Geochimica et Cosmochimica Acta (31) 313-337
The significant known hydrated borate mineral assemblages (principally of the western United States) in the system Na2O-CaO-MgO-B2O3-H2O are expressible in three ternary composition diagrams. Phase rule interpretation of the diagrams is consistent with observation, if the activity of H2O is generally considered to be determined by the geologic environment. The...
Pressure derivatives of elastic moduli of fused quartz to 10 kb
L. Peselnick, R. Meister, W.H. Wilson
1967, Journal of Physics and Chemistry of Solids (28) 635-639
Measurements of the longitudinal and shear moduli were made on fused quartz to 10 kb at 24·5°C. The anomalous behavior of the bulk modulus K at low pressure, &#x2202;K&#x2202;P&lt; 0">∂K∂P< 0, begins to approach the “normal” behavior of solids, &#x2202;K&#x2202;P&gt; 0">∂K∂P> 0,...
On the chemistry of Jupiter's upper atmosphere
W.C. Saslaw, R.L. Wildey
1967, Icarus (7) 85-93
We conduct a first investigation into the ion-molecule chemistry of the upper Jovian atmosphere. Experimental results show that intense ultraviolet radiation reacts with the constituents of the Jovian atmosphere to produce C2H4, C2H6, C3H8, and higher polymers. The general procedure for calculating both equilibrium and nonequilibrium abundances of these products...
Geomagnetic polarity epochs: Nunivak Island, Alaska
A. Cox, G. B. Dalrymple
1967, Earth and Planetary Science Letters (3) 173-177
New paleomagnetic and potassium-argon dating measurements have been made of basalt flows from Nunivak Island, Alaska, with the following results. (1) The best estimate of the age of the Brunhes/Matuyama polarity epoch boundary is found to be 0.694 m.y. (2) The best...
Sulfide solubilities in alteration-controlled systems
J.J. Hemley, C. Meyer, C.J. Hodgson, A.B. Thatcher
1967, Science (158) 1580-1582
Solubilities of sphalerite (ZnS) and galena (PbS) were determined at 300° to 500°C and 1000 bars total pressure in a chemical environment buffered...
Sierra Nevada batholith
P. C. Bateman, J. P. Eaton
1967, Science (158) 1407-1417
The batholith was generated within a synclinorium....
Mineral and chemical variations within an ash-flow sheet from Aso caldera, Southwestern Japan
P. W. Lipman
1967, Contributions to Mineralogy and Petrology (16) 300-327
Although products of individual volcanic eruptions, especially voluminous ash-flow eruptions, have been considered among the best available samples of natural magmas, detailed petrographic and chemical study indicates that bulk compositions of unaltered Pleistocene ash-flow tuffs from Aso caldera, Japan, deviate significantly from original magmatic compositions. The last major ash-flow sheet...
The fractionation of nickel between olivine and augite as a geothermometer
T.A. Hakli, T. L. Wright
1967, Geochimica et Cosmochimica Acta (31) 877-884
The coexisting olivine, clinopyroxene and glass of five samples collected from the Makaopuhi lava lake in Hawaii, at temperatures ranging from 1050 to 1160°C were analysed for nickel with an electron probe microanalyser. The results strongly suggest that the distribution of nickel between these three phase pairs well obeys the...
The ternary system K2SO4 MgSO4 CaSO4
J.J. Rowe, G.W. Morey, C.C. Silber
1967, Journal of Inorganic and Nuclear Chemistry (29) 925-942
Melting and subsolidus relations in the system K2SO4MgSO4CaSO4 were studied using heating-cooling curves, differential thermal analysis, optics, X-ray diffraction at room and high temperatures and by quenching techniques. Previous investigators were unable to study the binary MgSO4CaSO4 system and the adjacent area in the ternary system because of the decomposition of MgSO4 and...
Field Methods for the Study of Slope and Fluvial Processes
Luna Bergere Leopold, editor(s)
1967, Revue de Géomorphologie Dynamique (17) 147-187
In Belgium during the summer of 1966 the Commission on Slopes and the Commission on Applied Geomorphology of the International Geographical Union sponsored a joint symposium, with field excursions, and meetings of the two commissions. As a result of the conference and associated discussions, the participants expressed the view that...
Observations on unmeasured rivers
Luna Bergere Leopold, Herbert E. Skibitzke
1967, Geografiska Annaler, Series A: Physical Geography (49) 247-255
An analysis of data on hydraulic parameters collected during a single boat trip down a river system is presented, plotted in form of the hydraulic geometry. A dimensionless rating curve is used to estimate bankfull and average discharge for basins of various sizes. When compared with gaging station data, estimates...
