Sea level as affected by river runoff, eastern United States
R.H. Meade, K.O. Emery
1971, Science (173) 425-428
Variations in annual river inflow account for 7 to 21 percent of the total variation in average annual sea level along the Atlantic and Gulf of Mexico coasts of the United States. This compares with 29 to 68 percent of the total variation that can be attributed to the secular...
Eggshell thickness in mourning dove populations
J.F. Kreitzer
1971, Journal of Wildlife Management (35) 563-564
Eggs (n = 452) of the mourning dove (Zenaidura macroura) were collected from 9 states in 1969 and 11 states in 1970, and shell thickness was compared with that of eggs (n = 97) collected from 24 states during the years 1861 to 1935. Mean shell thickness did not differ...
Disappearance and persistence of aldrin after five annual applications
L.J. Korschgen
1971, Journal of Wildlife Management (35) 494-500
Investigation was initiated in 1965 to ascertain the disappearance rate of aldrin applied on loam soils at the recommended level of 1.5 lb per acre from 1960 through 1964. There was no further application of pesticides. Sampling began in 1965 and extended into 1970. Data from gas chromatographic analyses of...
Potassium-argon Ages from the Pololu Volcanic Series, Kohala Volcano, Hawaii
G. Brent Dalrymple
1971, Bulletin of the Geological Society of America (82) 1997-2000
Potassium-argon ages on five lava flows from the Pololu Volcanic Series, thought to be among the oldest rocks exposed on the island of Hawaii, indicate that the main subaerial shield-building phase of Kohala Volcano occurred about 0.7 ± 0.15 m.y. ago and that most of...
Contrasting behavior of P, Ti, and Nb in a differentiated high-alumina olivine tholeiite and a calc-alkaline andesitic suite
A. T. Anderson, David Gottfried
1971, Bulletin of the Geological Society of America (82) 1929-1941
Crystallization differentiation in a low-K2O, high-Al2O3 olivine tholeiite (Hat Creek, California) yields segregation veins of basaltic andesite composition, and residual, interstitial glasses of dacite and rhyolite composition. P, Ti, and probably Nb, are progressively enriched in segregation veins and residual dacitic glass by crystallization of olivine, plagioclase, augite, and magnetite. P...
Origin of ridge-top depressions by large-scale creep in the Olympic Mountains, Washington
Rowland W. Tabor
1971, Bulletin of the Geological Society of America (82) 1811-1822
In the high mountain area of the Olympic Mountains, Washington, there are many troughlike depressions on and essentially parallel to ridge tops. The troughs are mostly developed on rocks with strong planar anisotropy: slate, sandstone, and phyllite. Similar features in Europe, Japan, and New Zealand...

Fractionation of minor elements between galena and sphalerite, Darwin lead-silver-zinc mine, Inyo County, California and its significance in geothermometry
Wayne E. Hall, Harry J. Rose Jr., Frederick Otto Simon
1971, Economic Geology (66) 602-606
Minor element abundances were determined for galena and sphalerite from the Darwin mine, Inyo County, California. The temperature of deposition was calculated from the distribution coefficients determined experimentally by Bethke and Barton (1971) for cadmium and manganese in coexisting galena and sphalerite. The fractionation of...

The influence of pH on the efficacy and residues of quinaldine
J.B. Sills, J. L. Allen
1971, Transactions of the American Fisheries Society (100) 544-545
Quinaldine, an anesthetic for fish, loses its effectiveness in solutions having pH values less than 6. Measured quantities of un‐ionized quinaldine in solution compared favorably with calculated values at selected pHˈs. Quinaldine residues in largemouth bass (Micropterus salmoides) anesthetized at various pHˈs verify that only the un‐ionized portion in solution...
Geochemistry of water
O.P. Bricker
1971, Eos, Transactions, American Geophysical Union (52) IUGG302-IUGG305
The quadrennium 1967–1970 has been a productive period in the field of water geochemistry. Field studies, laboratory investigations, and theoretical considerations have led to significant advances in our knowledge of the chemical behavior of natural waters and of the solid earth materials that contain them. A symposium on trace inorganics...

Thomas L. Wright
1971, Eos, Earth and Space Science News (52) 57-62
The field of volcanology has expanded greatly in the years 1967–1970, and work on active volcanoes has kept pace with this expansion. I have restricted this summary and the accompanying bibliography to studies by U.S.‐based investigators of active or...

Boulder Creek batholith, Colorado part II: Isotopic age of emplacement and morphology of zircon
Thomas W. Stern, George Phair, Marcia F. Newell
1971, Bulletin of the Geological Society of America (82) 1615-1633
Zircon separated from six rocks whose compositions spanned the range of differentiation in the Boulder Creek batholith yielded a “discordia” age of emplacement of 1725 m.y., close to the average PB207/Pb206 age 1720 m.y.) and indicating that the constituent rocks are cogenetic within approximately ± 20 m.y. Statistical studies show that...
Quaternary faulting in the eastern Alaska Range
D.H. Richter, N.A. Matson Jr.
1971, Bulletin of the Geological Society of America (82) 1529-1540
Quaternary faulting is well displayed along the Denali fault system and the recently recognized and related Totschunda fault system in the eastern Alaska Range. The principal movement on both fault systems is right-lateral strike-slip. Offset glacial features of Wisconsin age indicate minimum Holocene slip rates of 1.1 to 3.5 cm...

The apparent ages (32 lead/alpha and 6 Pb206/U238) of zircon as plotted on an isochron map of the Boulder Creek batholith define the following pattern: (1) very high ages (1600 to 1900 m.y.) within the outermost border zone on the southwest, south, and southeast; (2) transitional high ages (1300 to...

Comparison of SLAR images and small-scale, low-sun aerial photographs
Malcolm M. Clark
1971, Bulletin of the Geological Society of America (82) 1735-1742
A comparison of side-looking airborne radar (SLAR) images and black and white aerial photos of similar scale and illumination of an area in the Mojave Desert of California shows that aerial photos yield far more information about geology than do SLAR images because of greater resolution, tonal range, and geometric...

An aeromagnetic and aeroradioactivity survey of Liberia, West Africa
John C. Behrendt, Cletus S. Wotorson
1971, Geophysics (36) 590-604
A 140,000 km aeromagnetic and total-count gamma radiometric survey was made over Liberia in 1967-68 along north-south lines spaced 0.8 km over land and 4 km over the continental shelf. The data approximately delineate the boundary between the Liberian (ca. 2700 m.y.) age province in...
Age of emplacement of Riley County, Kansas, kimberlites and a possible minimum age for the Dakota Sandstone
Douglas G. Brookins, Charles W. Naeser
1971, Bulletin of the Geological Society of America (82) 1723-1725
Field evidence suggests that the kimberlites of Riley County, Kansas, were emplaced into Lower Permian rocks in post-Dakota Sandstone time. The Dakota Sandstone in Kansas is thought to be earliest Late Cretaceous in age; thus the maximum age of emplacement of the kimberlites is approximately...
Structure and petrology of the alpine-type peridotite at Burro Mountain, California, U.S.A.
R. A. Loney, G. R. Himmelberg, R. G. Coleman
1971, Economic Geology (12) 245-309
The alpine-type peridotite at Burro Mountain is a partially serpentinized harzburgite-dunite body approximately 2 km in diameter. It lies in a chaotic mélange derived from the Franciscan Formation (Upper Jurassic to Upper Cretaceous) of the southern Coast Ranges of California. The peridotite is bounded on the east by a vertical fault...
A chemical study of serpentinization — Burro Mountain, California
R. G. Coleman, T. E. Keith
1971, Journal of Petrology (12) 311-328
Serpentinized dunites and harzburgites from the Burro Mountain peridotite show no change in the ratio of iron and magnesia to silica when compared with the same ratio for the unserpentinized equivalents. The mineral assemblage resulting from serpentinization consists of lizardite-chrysotile, brucite, and magnetite and is determined by the original...
