Evidence for an early recent warm interval in northwestern Alaska
David S. McCulloch, David M. Hopkins
1966, Geological Society of America Bulletin (77) 1089-1108
A warm interval that began at least 10,000 years ago and lasted until at least 8300 years ago is recorded in the coastal tundra covered area of northwestern Alaska by the presence of fossil wood of tree size or tree species, fossil beaver-gnawed wood found beyond the modern range of beaver, evidence of ice-wedge melting, buried soils, and soils that...
“Iron Water” from wells: Causes and prevention
M.E. Broom
1966, Groundwater (4) 18-21
Chemical analyses of ground‐water samples taken from differing depths in a four‐county area in east Texas showed a general stratification with respect to dissolved iron, pH and hardness. On the basis of this stratification the waters of the ground‐water reservoir were divided into a shallow zone of oxidation, A; a deep zone of...
Hydrology of limestone terranes in the coastal plain of the Southeastern United States
V. T. Stringfield, H. E. LeGrand
1966, Special Paper of the Geological Society of America (93) 1-46
The very productive limestone aquifers of Tertiary and Quaternary age in the Coastal Plain of the Southeastern States contain a water-table circulation system where aquifers are at or near the land surface; the Tertiary limestone unit is a homoclinal artesian system confined beneath younger beds in coastal areas.The Tertiary limestone...
The system Cu-Ag-S
Brian J. Skinner
1966, Economic Geology (61) 1-26
Compositions on the join Cu 2 S-Ag 2 S were studied with X-ray diffractometer heating stage. Low-temperature phases, which break down at temperatures between 67 degrees and 119 degrees C, are chalcocite, stromeyerite, Cu (sub O.8) Ag (sub 1.2) S, jalpaite, and acanthite. High-temperature phases, all cation-disordered, are hexagonal close-packed (high chalcocite), face-centered cubic...

Hawaiian Volcano Observatory record book 1960, 1965, and 1966
1966, Report
The Hawaiian Volcano Observatory (HVO) record books are annual journals in which field observations of eruptive activity at Kīlauea and Mauna Loa volcanoes, on the Island of Hawaiʻi, were compiled by HVO staff for most years from 1912 through early 1966. In addition to descriptive observations, the record books also...

Waste injection into a deep limestone in northwestern Florida
J.T. Barraclough
1966, Groundwater (4) 22-24
During a three-month trial period, 70 million gallons of industrial wastes were successfully injected at moderate pressures into a deep limestone in the westernmost part of Florida. The movement of these wastes is expected to be predominantly southward toward the natural discharge area which is presumed to be far out...

Observed variations in the strontium concentration of sea water
E.E. Angino, G.K. Billings, N. Andersen
1966, Chemical Geology (1) 145-153
On samples obtained from five widely separated areas of the North Atlantic Ocean 91 determinations of strontium were made. These include surface and deep-water samples from both the cold North Atlantic area and the warm subtropical Caribbean area. The results differ from...
Chemical composition of phosphorites of the Phosphoria Formation
R. A. Gulbrandsen
1966, Geochimica et Cosmochimica Acta (30) 769-778
The chemical composition, both major and minor constituents, of 60 samples of phosphorite from the Phosphoria Formation was determined. Major constituents of the average phosphorite are, by weight per cent: SiO2, 11·9; Al2O3, 1·7; Fe2O3,1·1; MgO, 0·3; CaO, 44·0; Na2O, 0·6; K2O, 0·5; total H2O, 2·2; H2O−, 0·6; TiO2, 0·1;...
Some alkali and titania analyses of tektites before and after G-1 precision monitoring
D.B. Tatlock
1966, Geochimica et Cosmochimica Acta (30) 123-128
A comparison of 55 older analyses of Australasian tektites with 110 modern precisely monitored analyses suggests that more than half of the older alkali and titania determinations are decidedly inaccurate and misleading. Deviations of the older analyses from the restricted values of the...
Composition and evolution of the continental crust as suggested by seismic observations
L. C. Pakiser, R. Robinson

The average composition of the continental crust is more mafic than hitherto supposed. The conterminous United States can be divided, on the basis of seismic structure, into ten regions. The seven western and the three eastern regions can be termed western and eastern...

1966, Earth and Planetary Science Letters (1) 387-391
Radioisotope analyses of basalt samples from Hawaii, Japan, and Iwo Jima show that: (1)234U and238U are virtually in radioactive equilibrium, (2)230Th exceeds equilibrium values in all these samples, (3)210Pb concentrations range from 10–200% of the equilibrium values and average 30% deficient, and...
Some Debye temperatures from single-crystal elastic constant data
R. A. Robie, J.L. Edwards
1966, Journal of Applied Physics (37) 2659-2663
The mean velocity of sound has been calculated for 14 crystalline solids by using the best recent values of their single‐crystal elastic stiffness constants. These mean sound velocities have been used to obtain the elastic Debye temperatures θDe for these materials. Models of the three wave velocity surfaces for calcite are illustrated....
