Equilibrium-disequilibrium relations in the Monte Rosa Granite, Western Alps: Petrological, Rb-Sr and stable isotope data
M. Frey, J.C. Hunziker, J. R. O’Neil, H.W. Schwander
1976, Contributions to Mineralogy and Petrology (55) 147-179
Nine samples from the Monte Rosa Granite have been investigated by microscopic, X-ray, wet chemical, electron microprobe, stable isotope and Rb-Sr and K-Ar methods. Two mineral assemblages have been distinguished by optical methods and dated as Permian and mid-Tertiary by means of Rb-Sr age determinations. The Permian assemblage comprises quartz,...
Leasing policies for the extractive resources
E. D. Attanasi, S.R. Johnson
1976, The Annals of Regional Science (10) 36-49
Much of the available analysis of policies for the disposal of publicly held resources is based on comparatively straightforward extensions of the neoclassical pricing and allocation theory. As such, these analyses have to a large extent not fully incorporated the fact that firms normally acquire rights...
Strontium isotopic geochemistry of the volcanic rocks and associated megacrysts and inclusions from Ross Island and vicinity, Antarctica
J. S. Stuckless, R.L. Ericksen
1976, Contributions to Mineralogy and Petrology (58) 111-126
Twelve whole-rock samples of volcanic rocks and a composite of 11 basanitoid samples from Ross Island and vicinity, Antarctica show a narrow range of 87Sr/86Sr ratios from 0.70305 to 0.70339. This range is consistent with a model of differentiation from a single parent magma, but the data allow a 30% variation in...
On the origin of the livingstonite deposits at Huitzuco, Guerrero, Mexico
G. Tunell, R. E. Learned, E.F. Lawrence
1976, Mineralium Deposita (11) 71-82
Livingstonite is the principal ore mineral in the deposits of the Huitzuco District in the State of Guerrero, Mexico. The ore is found in the lower part of the Morelos Formation, which consists of a thick bed of sedimentary anhydrite containing lenses of dolomite and dolomite breccia. In the unweathered...
Volcanic rocks and processes of the Mid-Atlantic Ridge rift valley near 36 ° 49′ N
R. Hekinian, J.G. Moore, W.B. Bryan
1976, Contributions to Mineralogy and Petrology (58) 83-110
Eighty samples of submarine basaltic lava were sampled from an 8 km segment of the floor and walls of the inner rift valley of the Mid-Atlantic Ridge during the French American Mid-Ocean Undersea Study (project Famous). The samples were collected from outcrops and talus slopes by the three submersibles:...
Relative influence upon microwave emissivity of fine-scale stratigraphy, internal scattering, and dielectric properties
A. W. England
1976, Pure and Applied Geophysics PAGEOPH (114) 287-299
The microwave emissivity of relatively low-loss media such as snow, ice, frozen ground, and lunar soil is strongly influenced by fine-scale layering and by internal scattering. Radiometric data, however, are commonly interpreted using a model of emission from a homogeneous, dielectric halfspace whose emissivity derives exclusively...
On simultaneous tilt and creep observations on the San Andreas Fault
M.J.S. Johnston, S. McHugh, S. Burford
1976, Nature (260) 691-693
THE installation of an array of tiltmeters along the San Andreas Fault1 has provided an excellent opportunity to study the amplitude and spatial scale of the tilt fields associated with fault creep. We report here preliminary results from, and some implications of, a search for interrelated surface...
Serpentinization and alteration in an olivine cumulate from the Stillwater Complex, Southwestern Montana
N.J. Page
1976, Contributions to Mineralogy and Petrology (54) 127-137
Some of the olivine cumulates of the Ultramafic zone of the Stillwater Complex, Montana, are progressively altered to serpentine minerals and thompsonite. Lizardite and chrysotile developed in the cumulus olivine and postcumulus pyroxenes; thompsonite developed in postcumulus plagioclase. The detailed mineralogy, petrology, and chemistry indicate that...
Problems in shallow land disposal of solid low-level radioactive waste in the united states
P. R. Stevens, G.D. DeBuchananne
1976, Bulletin of the International Association of Engineering Geology (13) 161-171
Disposal of solid low-level wastes containing radionuclides by burial in shallow trenches was initiated during World War II at several sites as a method of protecting personnel from radiation and isolating the radionuclides from the hydrosphere and biosphere. Today, there are 11 principal shallow-land burial sites in the United States...
Gravitational spreading of steep-sided ridges ("sackung") in western United States
D. H. Radbruch-Hall, D. J. Varnes, W. Z. Savage
1976, Bulletin of the International Association of Engineering Geology (13) 23-35
Large-scale gravitational spreading and movement along fractures of steep-sided ridges in the mountainous areas of the western United States are characterized by linear fissures, trenches, and uphill-facing scarps on tops and sides of ridges. Spreading appears to take place by movement along disconnected planes and/or by...
Landslides - Cause and effect
D. H. Radbruch-Hall, D. J. Varnes
1976, Bulletin of the International Association of Engineering Geology (13) 205-216
Landslides can cause seismic disturbances; landslides can also result from seismic disturbances, and earthquake-induced slides have caused loss of life in many countries. Slides can cause disastrous flooding, particularly when landslide dams across streams are breached, and flooding may trigger slides. Slope movement in general is a major process of...
An investigation of the critical liquid-vapor properties of dilute KCl solutions
R.W. Potter II, R.S. Babcock, G.K. Czamanske
1976, Journal of Solution Chemistry (5) 223-230
The three parameters that define the critical point, temperature, pressure, and volume have been experimentally determined by means of filling studies in a platinum-lined system for five KCl solutions ranging from 0.006 to 0.568m. The platinum-lined vessels were used to overcome the problems with corrosion experienced...
Report of the American Ornithologists' Union Committee on Conservation 1975-76
W.B. King, G.V. Byrd, J.J. Hickey, C. B. Kepler, W. Post, H.A. Raffaele, P. F. Springer, H.F. Snyder, C.M. White, J.N. Wiley
1976, The Auk (93) 1DD-19DD
This Committee's report for 1974-75 (Marshall et al. 1975, Auk 92 (4, Suppl.): lB-16B) summarized activities affecting bird conservation in the United States and Canada since 1973, including new legislation, international activities, avian conflicts with industrial and population growth, and habitat preservation. It also summarized the status of many of...
[Book review] American sportsmen and the origins of conservation
Richard C. Banks
1976, The Auk (93) 864-865
The relationship of this book to ornithology is so indirect that the work barely merits a review on these pages. In a rather subtle way, however, the book may have a considerable effect on at least one aspect of ornithology, that involving scientific collecting. In essence, the volume is an...
Nationwide residues of organochlorines in wings of adult mallards and black ducks, 1972-73
Donald H. White, R.G. Heath
1976, Pesticides Monitoring Journal (9) 176-185
Organochlorine residues in wings of adult mallards and black ducks were monitored during the 1972-73 hunting season. DDE, DDT, DDD, dieldrin, and polychlorinated biphenyls (PCB's) were present in all samples. Mallard wings from Alabama contained the highest mean levels of DDE, DDT, DDD, dieldrin, and PCB's. Mallards and black ducks...

R.E. Kirby
1976, Canadian Field-Naturalist (90) 423-431
Beaver flowages and associated wetlands on the Chippewa National Forest, north-central Minnesota, were photographed from the ground and from the open side window of a small high-wing monoplane. The 35-mm High Speed Ektachrome transparencies obtained were used to map the cover-type associations visible on the aerial photographs. Nearly vertical aerial...
Thermal adaptiveness of plumage color in screech owls
James A. Mosher, Charles J. Henny
1976, The Auk (93) 614-619
Clinal variation in the relative proportions of red and gray plum- age phases in Screech Owls (Otus asio) was analyzed by Owen (1963) and Marshall (1967). This variation was well known prior to Owen's work, but was misinterpreted (Baird, et al. 1874, Hasbrouck 1893, Allen 1893).]Laurel VanCamp and Charles Henny...
The effects of orchard pesticide applications on breeding robins
E.V. Johnson, G.L. Mack, D.Q. Thompson
1976, The Wilson Bulletin (88) 16-35
From 1966 through 1968, robins reproduced successfully in commercial apple orchards which were periodically sprayed with DDT, dieldrin, and other pesticides. Observations by a Z-man team using walkie-talkies revealed that breeding robins obtained essentially all food for themselves and nestlings from unsprayed areas adjacent to the orchards. Invertebrate trapping in...
