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....

Rare earths in phosphorites: Geochemistry and potential recovery
Z. S. Altschuler, Sol Berman, Frank Cuttitta
1966, Open-File Report 66-3
Rare earths are but trace constituents of marine apatite. However, as millions of tones of such apatite are dissolved annually to make phosphoric acid, an opportunity exists for greatly increasing RE output as by-product of fertilizer production. New, complete, quantitative analysis of RE in representative apatite concentrates reveal that the...
Uranium and lead isotopic stability in a metamict zircon under experimental hydrothermal conditions
R.T. Pidgeon, J. R. O’Neil, L. T. Silver
1966, Science (154) 1538-1540
Abstract. Disturbance of the uranium-lead isotopic system in a metamict Ceylon zircon has been produced in a 2 molal NaCI solution at 500°C...
Composition and evolution of the continental crust as suggested by seismic observations
L. C. Pakiser, R. Robinson
1966, Tectonophysics (3) 547-557
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...
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...
Life history of the gizzard shad, Dorosoma cepedianum (Le Sueur), in western Lake Erie
Anthony Bodola
1966, Fishery Bulletin (65) 391-425
The rapid increase in the stocks of gizzard shad in Lake Erie since 1950 unquestionably had an important effect on the ecology of the lake. The present study, based on almost 24,000 fish collected by various means in 1952-55 in or near the island area of western Lake Erie was...

Effects of weathering on the UPb ages of zircon from the Morton Gneiss, Minnesota
T. W. Stern, S. S. Goldich, M. F. Newell
1966, Earth and Planetary Science Letters (1) 369-371
Weathering has caused large losses of lead from the zircon in the residual clay derived from the Morton Gneiss of southwestern Minnesota, drastically reducing the 206Pb/238U and the 207Pb/235U ages. The 207Pb/206Pb age probably has not been significantly affected. Loss of lead by leaching during weathering has not been adequately...

Some blood chemistry values for five Chesapeake Bay area fishes
J. B. Hunn, P.F. Robinson
1966, Chesapeake Science (7) 173-175
Blood samples from gizzard shad,largemouth bass, white perch, pumpkinseed, and toadfish were analyzed for hemoglobin, total plasma protein, total plasma cholesterol, and ion concentrations of plasma sodium, potassium, and chloride. The hemoglobin concentration and total plasma cholesterol found in a given species seem to have positive correlation with the customary activity level...

Seasonal and depth distribution of larval bloaters (Coregonus hoyi) in southeastern Lake Michigan
LaRue Wells
1966, Transactions of the American Fisheries Society (95) 388-396
Larvae of bloaters (Coregonus hoyi) were sampled systematically in southeastern Lake Michigan, off Saugatuck, Michigan, from 9 April to 22 August 1964; limited additional sampling was done on 15 October. All collections were made with a 1-m plankton net of 0.66-mm mesh. A standard series of samples consisted of...

Crystallization of tholeiitic basalt in Alae Lava Lake, Hawaii
D. L. Peck, T. L. Wright, J.G. Moore
1966, Bulletin Volcanologique (29) 629-655
The eruption of Kilauea Volcano August 21–23, 1963, left 600,000 cubic meters of basaltic lava in a lava lake as much as 15 meters deep in Alae pit crater. Field studies of the lake began August 27 and include repeated core drilling, measurements of temperature in the crust and melt,...
Disequilibrium of the 238U series in basalt

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...
