Devonian of the Southwestern United States
F. G. Poole, D.L. Baars, H. Drewes, P. T. Hayes, K. B. Ketner, E. D. McKee, C. Teichert, J. S. Williams
1967, Conference Paper, International symposium on the Devonian system
The structural framework that controlled Devonian deposition consisted of, from west to east: (1) a eugeosynclinal area in northern California and western Nevada; (2) a miogeosynclinal area in southeastern California, eastern Nevada, and western Utah; and (3) a cratonic area in Arizona, eastern Utah, Colorado, New Mexico, and western...
Devonian of the Appalachian Basin, United States
William A. Oliver, Wallace De Witt, John M. Dennison, D.M. Hoskins, John W. Huddle
1967, Conference Paper, International symposium on the Devonian system
Although Devonian rocks in the Appalachians have been studied for more than 150 years, they are poorly known in most of the area. The nearly complete Devonian sequence in New York has been established as the North American standard of reference. The structural belt that includes unmetamorphosed Devonian geosynclinal...
Succession of rugose coral faunas in the Lower and Middle Devonian of eastern North America
William Albert Oliver Jr.
1967, Conference Paper, International symposium on the Devonian system
Rocks of Early Devonian age are widely but sporadically distributed in the eastern half of North America and coral studies are based on a very incomplete record. Middle Devonian rocks are thicker and cover a greater area. Both Early and Middle Devonian corals are more similar to western European species...

Northern part, Ten Mile and Taunton River basins
John R. Williams, Richard E. Willey
1967, Massachusetts Hydrologic - Data Report 10
The northern part of the Ten Mile and Taunton River basins is an area of about 195 square miles within Norfolk, Plymouth, and Bristol Counties in southeastern Massachusetts. The northern boundary of the area (plate 1) is the drainage divide separating these basins from that of the Charles, Neponset, and...
Hydrologic and climatologic data, 1966, Salt Lake County, Utah
A. G. Hely, Reed W. Mower, C. A. Horr
1967, Utah Basic-Data Release 13
An investigation of the water resources of Salt Lake County, Utah, was undertaken by the Water Resources Division of the U.S. Geological Survey in July 1963. This investigation is a cooperative project financed equally by the State of Utah and the Federal Government in accordance with an agreement between the...
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...

Fractionation of rare-earth elements in allanite and monazite as related to geology of the Mt. Wheeler mine area, Nevada
D. E. Lee, H. Bastron
1967, Geochimica et Cosmochimica Acta (31) 339-356
Rare-earth contents of 20 allanites and 13 monazites, accessory minerals from a restricted outcrop area of intrusive granitic rocks, are reported. A quantity called sigma (Σ), which is the sum of the atomic percentages of La, Ce and Pr, is used...

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 KAr ages were determined for sanidine samples from 10 rhyolite domes of the Mono and Inyo Craters to test the applicability of KAr dating to volcanic rocks of Recent age. Comparison of the results with ‘blank’ and dosed analyses shows...
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...
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...
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...
An operational theory of laser-radar selenodesy

1967, Icarus (6) 315-347
A theory of the utilization of laser techniques for ranging from the Earth to the Moon for the purpose of providing control points on the lunar surface at which the figure of the Moon is measured to an accuracy at least an order of magnitude better than that of...
The occurrence and origin of lamellar troilite in iron meteorites
R. Brett, E.P. Henderson
1967, Geochimica et Cosmochimica Acta (31) 721-730
A number of iron meteorites contain elongated inclusions consisting predominantly of troilite, which have been termed Reichenbach lamellae. Two types of inclusions exist, the first up to 6 cm long and 0·2 mm wide, the second up to 2 cm long and 3 mm wide. The first type contains troilite...
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...
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...

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...
