The tullibee
Stanford H. Smith
1966, Minnesota Conservation Volunteer (29) 49-50
Early explorers and settlers of the northeastern United States and southern Canada found lakes teeming with fish that had white flesh and were good to eat. The larger of these they called whitefish, differentiating two kinds- the lake whitefish and the round or menominee whitefish. These looked much...
Stream quality in Appalachia as related to coal-mine drainage, 1965
James E. Biesecker, J. Richard George
1966, Circular 526
A stream-quality reconnaissance at 318 locations in May 1965 offered the first opportunity for a contemporaneous regional collection and appraisal of water-quality data in Appalachia. The results provide a means of regional comparison of the influence of coal-mine drainage on stream quality at approximately median streamflow. The results disclose that...
Mineral exploration and soil analysis using in situ neutron activation
F. E. Senftle, A.F. Hoyte
1966, Nuclear Instruments and Methods (42) 93-103
A feasibility study has been made to operate by remote control an unshielded portable positive-ion accelerator type neutron source to induce activities in the ground or rock by “in situ” neutron irradiation. Selective activation techniques make it possible to detect some thirty or...
Hydrologic and climatologic data, 1965, Salt Lake County, Utah
W.V. Iorns, Reed W. Mower, C. A. Horr
1966, Utah Basic-Data Release 12
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...
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....
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,...
Genetic relations of oceanic basalts as indicated by lead isotopes
M. Tatsumoto
1966, Science (153) 1094-1101
The isotopic compositions of lead and the concentrations of lead, uranium, and thorium in samples of oceanic tholeiite and alkali suites are determined, and the genetic relations of the oceanic basalts are discussed. Lead of the oceanic tholeiites has a varying lead-206 : lead-204 ratio between 17.8 and 18.8, while...
Oxygen fugacities directly measured in magmatic gases
M. Sato, T. L. Wright
1966, Science (153) 1103-1105
An electrochemical device was used to measure the fugacity of oxygen (fO2) in holes drilled through the crust of Makaopuhi lava lake, Kilauea Volcano, Hawaii. Results obtained within 6 months of the lake formation show that log fO2 normally varies linearly with the reciprocal of the absolute temperature, and that...
Hydrologic and climatologic data collected through 1964, Salt Lake County, Utah
W.V. Iorns, Reed W. Mower, C. A. Horr
1966, Utah Basic-Data Release 11
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...
Exposure of basement rock on the continental slope of the bering sea
D.W. Scholl, E. C. Buffington, D.M. Hopkins
1966, Science (153) 992-994
Profiles of repetitive seismic reflections reveal that the Bering continental slope, outer shelf, and rise overlay an acoustically reflective "basement" which extends at least 750 kilometers parallel to the trend of the slope. This acoustic basement is usually covered by several hundred meters of stratified sediments at the top and...
Geomagnetic polarity epochs: A new polarity event and the age of the Brunhes-Matuyama boundary
Richard R. Doell, G. B. Dalrymple
1966, Science (152) 1060-1061
Recent paleomagnetic-radiometric data from six rhyolite domes in the Valles Caldera, New Mexico, indicate that the last change in polarity of the earth's magnetic field from reversed to normal (the Brunhes-Matuyama boundary) occurred at about 0.7 million years ago. A previously undiscovered geomagnetic polarity event, herein named the "Jaramillo normal...
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...
Some effects of Heptachlor on bluegills (Lepomis macrochirus)
Austin K. Andrews, Bruce E. Stebbings, Charles C. Van Valin
1966, Transactions of the American Fisheries Society (95) 297-309
In complementary studies of the chronic effects of heptachlor on bluegills, four similar earthen ponds were treated once with different concentrations of heptachlor, and the fish in six plastic pools were routinely fed different levels of heptachlor. A fifth pond and two plastic pools were used as controls. Higher dosages...
