Seismic survey in the region of recent earthquake activity near Denver, Colorado
B.F. Rummerfield, A. Peter Olson, D.B. Hoover
1968, Geophysics (33) 915-925
A seismic-reflection survey was carried out near Denver, Colorado, for the U. S. Geological Survey, to determine if structures exist in the 12,000-ft sedimentary section or in the Precambrian basement that might explain the recent earthquake activity. No major faults were revealed in the sedimentary section. Reflections from a steeply dipping horizon believed to be in the basement complex may be indicative of faulting; however, the magnitude cannot...
Population characteristics and physical condition of alewives, Alosa pseudoharengus, in a massive die-off in Lake Michigan, 1967
Edward H. Brown Jr.
1968, Technical Report 13
The length, age and sex compositions of dead and dying alewives collected in June 1967 at six locations in southern, central, and northern Lake Michigan are compared with those of fish taken in experimental trawls at five locations in April and June 1967. Behavior at the time of death, condition...

Reward banding to determine reporting rate of recovered mourning dove bands
R. E. Tomlinson
1968, Journal of Wildlife Management (32) 6-11
Reward bands placed on the other leg of certain regularly banded immature mourning doves (Zenaidura macroura) were used to develop information on reporting rates of recovered dove bands. Reports from 15 widely separated sections of the United States showed considerable variation in recovery rate of doves both with and without...

Effects of lamprey larvicides on invertebrates in streams
Richard L. Torblaa
1968, Special Scientific Report - Fisheries 572
This study was conducted on five streams tributary to Lake Superior and four tributary to Lake Michigan. Samples of the bottom fauna before and after chemical treatment revealed that most groups of aquatic organisms were not adversely affected by exposure to larvicides. The total number of invertebrates was smaller 1...
Turnover and urinary excretion of free and acetylated MS-222 rainbow trout, Salmo gairdneri
J. B. Hunn, R.A. Schoettger, W. A. Willford
1968, Journal of the Fisheries Research Board of Canada (25) 25-31
Rainbow trout (Salmo gairdneri) anesthetized in 100 mg/liter of M.S. 222 at 12 C excreted the drug in free and acetylated forms via the urine during a 24-hr recovery period in freshwater. Of the M.S. 222 excreted, 77-96% was acetylated. Blood levels of free drug in anesthetized trout approximated 75%...

Variation of Nb-Ta, Zr-Hf, Th-U and K-Cs in two diabase-granophyre suites
D. Gottfried, L. P. Greenland, E.Y. Campbell
1968, Geochimica et Cosmochimica Acta (32) 925-947
Concentrations of Nb, Ta, Zr, Hf, Th, U and Cs have been determined in samples of igneous rocks representing the diabase-granophyre suites from Dillsburg, Pennsylvania, and Great Lake, Tasmania.Niobium and tantalum have a three to fourfold increase with differentiation in each of the suites. The chilled margin of the Great...
Dissociation constants of KSO4- from 10°-50°C
A.H. Truesdell, P. B. Hostetler
1968, Geochimica et Cosmochimica Acta (32) 1019-1022
A cell without liquid junction was used to obtain dissociation constants for the reaction: KSO4− = K+ +SO42−. At 10°, 25°, 38° and 50°C, values for Kdiss KSO4− are, respectively, 0.195, 0.142, 0.117, and 0.095. At 25°C, , and <img class="imgLazyJSB inlineImage" title=""...

Effects of selective fusion on the thermal history of the earth's mantle
W.H.K. Lee
1968, Earth and Planetary Science Letters (4) 270-276
A comparative study on the thermal history of the earth's mantle was made by numerical solutions of the heat equation including and excluding selective fusion of silicates. Selective fusion was approximated by melting in a multicomponent system and redistribution of radioactive elements. Effects of selective fusion on the thermal models...
