Presentation and interpretation of chemical data for igneous rocks
T. L. Wright
1974, Contributions to Mineralogy and Petrology (48) 233-248
Arguments are made in favor of using variation diagrams to plot analyses of igneous rocks and their derivatives and modeling differentiation processes by least-squares mixing procedures. These methods permit study of magmatic differentiation and related processes in terms ofall of the chemical data available. Data are presented as they are reported...
Obsidian hydration profile measurements using a nuclear reaction technique
R.R. Lee, D.A. Leich, T.A. Tombrello, J.E. Ericson, I. Friedman
1974, Nature (250) 44-47
AMBIENT water diffuses into the exposed surfaces of obsidian, forming a hydration layer which increases in thickness with time to a maximum depth of 20–40 µm (ref. 1), this layer being the basic foundation of obsidian dating2,3....
Chemistry and mineralogy of garnet pyroxenites from Sabah, Malaysia
B. A. Morgan
1974, Contributions to Mineralogy and Petrology (48) 301-314
Garnet pyroxenites and corundum-garnet amphibolites from the Dent peninsula of eastern Sabah (North Borneo) occur as blocks in a slump breccia deposit of late Miocene age. The earliest formed minerals include pyrope-almandine garnet, tschermakitic augite, pargasite, and rutile. Cumulate textures are present in two of the...
A comparison of infrared, radar, and geologic mapping of lunar craters
T.W. Thompson, H. Masursky, R.W. Shorthill, G.L. Tyler, S.H. Zisk
1974, The Moon (10) 87-117
Between 1000 and 2000 infrared (eclipse) and radar anomalies have been mapped on the nearside hemisphere of the Moon. A study of 52 of these anomalies indicates that most are related to impact craters and that the nature of the infrared and radar responses is compatible...
3,800-Myr granitic gneiss in south-western Minnesota
S. S. Goldich, C. E. Hedge
1974, Nature (252) 467-468
WE have previously arrived at an age of 3,550 Myr for granitic1 gneiss in the vicinities of Morton and Montevideo in the Minnesota River valley, south-western Minnesota. We now report new Rb–Sr analyses (Table 1) and an age of 3,800 Myr for the fine grained foliated phase...
Ophiolites and oceanic crust
E.M. Moores, E.D. Jackson
1974, Nature (250) 136-139
OPHIOLITES consist of a pseudostratiform sequence, of harzburgite, tectonite, ultramafic and mafic cumulates sometimes including gabbro and quartz diorite (plagiogranite) intrusions, dolerite dyke swarms, pillow lava 1, and deep-sea sediments2-4. This assemblage occurs in all Phanerozoic mountain systems and is interpreted as fossil oceanic crust and uppermost mantle5-10. Outstanding problems...
Measurement in a marine environment using low cost sensors of temperature and dissolved oxygen
F.A. Godshall, R. L. Cory, D.E. Phinney
1974, Chesapeake Science (15) 178-181
Continuous records of physical parameters of the marine environment are difficult as well as expensive to obtain. This paper describes preliminary results of an investigative program with the purpose of developing low cost time integrating measurement and averaging devices for water temperature and dissolved oxygen.Measurements were made in an estuarine...
The status of the light-footed clapper rail
S.R. Wilbur
1974, American Birds (28) 868-870
Only 12 California marsh areas are presently believed to be inhabited by the Light-footed Clapper Rail, and eight of these appear to support only 5-15 birds apiece. Tentative estimates for the other four are: Anaheim Bay 200, Upper Newport 30-35, Los Penasquitos 30, and Tijuana Estuary 150. These...

Capture-recapture analysis of a wintering black-capped chickadee population in Connecticut, 1958-1993
C.S. Robbins
1974, American Birds (28) 273-274
We investigated the dynamics of a wintering population of Black-capped Chickadees (Parus atricapillus) using data from a long-term capture-recapture study. Goodness-of-fit and likelihood-ratio tests indicated that the standard Jolly-Seber model was inadequate for the data, so we explored different parameterizations of a model in which survival probability for new captures...
Electrophoresis as a management tool
R.P. Morgan II, J.A. Chapman, L.A. Noe, Charles J. Henny
1974, Transactions of the Northeast Fish and Wildlife Conference (31) 63-71
The theme of this 1974 Northeast Fish and Wildlife Conference is 'A New Era'. Indeed, it is a new era for improved techniques to assist in management of our fish and wildlife resources for the maximum benefit of all. In some cases, the new techniques are primarily used...
Optimal exploitation strategies for an animal population in a stochastic serially correlated environment
David R. Anderson
1974, Dissertation Abstracts International (35) 3107
Optimal exploitation strategies were studied for an animal population in a stochastic, serially correlated environment. This is a general case and encompasses a number of important cases as simplifications. Data on the mallard (Anas platyrhynchos) were used to explore the exploitation strategies and test several hypotheses because relatively...
Record confirmed of Bahama woodstar in Florida
H.P. Langridge, P.W. Sykes Jr.
1974, The Auk (91) 849-849
We reported a Bahama Woodstar (Calliphlox evelynae) at Lantana, Florida, 26 August through 13 October 1971 (1972, Amer. Birds 26: 52). At that time, there was reservation by some about the identification. Colored slides taken of the bird at roost were subsequently examined by James Bond and Frank B. Gill,...
Progress report on the North American Breeding Bird Survey
C.S. Robbins, W.T. Van Velzen
1974, Acta Ornithologica (14) 170-191
The Breeding Bird Survey has been monitoring bird population changes in the U.S.A. and Canada since 1966. Each cooperator makes 50 3-minute stops at 0.8-km intervals along randomly selected roadside routes in 4 to 4 1/2 hours on one morning in June of each year. Data from the 1500 to...
Effects of DDT on bobwhite quail adrenal gland
J.W. Lehman, T.J. Peterle, C.M. Mulls
1974, Bulletin of Environmental Contamination and Toxicology (11) 407-414
A wide range of responses to sublethal levels of DDT exist, many of which are species specific and vary within each species depending upon age, sex, and physiological state. Sublethal levels of DDT do cause an increase in the adrenal cortical tissue of bobwhite quail, which may cause increased secretion...
Chlorinated hydrocarbon and mercury residues in woodcock in the United States, 1970-71
D. R. Clark Jr., M. Anne Ross McLane
1974, Pesticides Monitoring Journal (8) 15-22
During Late 1970 and early 1971, 229 woodcock (Philohela minor) were collected from 23 Eastern and Midwestern States. Analyses for chlorinated hydrocarbons and mercury in these migratory birds showed generally low levels which are not considered dangerous to human consumers. In this survey, Louisiana woodcock had lower...
Residues of organochlorine pesticides, mercury, and PCB's in mourning doves from eastern United States--1970-71
J.F. Kreitzer
1974, Pesticides Monitoring Journal (7) 195-199
Mourning dove (Zenaidura macroura) breast muscle samples from birds collected in 1970-71 from Rhode Island, Pennsylvania, Maryland, Missouri, Kentucky, Virginia, Arkansas, Tennessee, North Carolina, South Carolina, Mississippi, Alabama, Georgia, Louisiana, and Florida were found to contain residues of DDT, DDE, DDD, polychlorinated biphenyls, dieldrin, mirex, mercury, and heptachlor epoxide in...
Avian eggshell thickness: Variability and sampling
Erwin E. Klaas, H. M. Ohlendorf, R.G. Heath
1974, The Wilson Bulletin (86) 156-164
Measurements of shell thickness of the eggs of five species were subjected to nested analyses of variance. The analyses separated variation into two or three levels for which variances and percentages of the total variation were derived. The results show that differences among measurements of the same egg contribute little...
