Western Stump Lake, a major canvasback staging area in eastern North Dakota
H.A. Kantrud
1986, Prairie Naturalist (18) 247-253
Large numbers of waterfowl, especially canvasback (Aythya valisineria), used Western Stump Lake as a staging area during most of October 1985. Selection of the lake as a conditioning site by this species likely is caused by extensive, shallow-water beds of sago pondweed (Potamogeton pectinatus) and lack of human disturbance. A...
The Valley and Ridge Province of eastern Pennsylvania - Stratigraphic and sedimentologic contributions and problems
Jack B. Epstein
1986, Geological Journal (21) 283-306
Many contributions that have led to a better understanding of Appalachian geology have resulted directly from work in the folded Appalachian Mountain and Great Valley sections of the Valley and Ridge physiographic province of eastern Pennsylvania. Disagreements have been common since H.D. Rogers first described the geology of the area...
Chloritoid-sillimanite assemblage from North Carolina.
D.J. Milton
1986, American Mineralogist (71) 891-894
The occurrence of sillimanite and Fe-rich chloritoid in apparent equilibrium in a quartzite near Charlotte, North Carolina, is reported. The implications for the kyanite-andalusite-sillimanite triple point are discussed.-J.A.Z....
URBAN STORMWATER-QUALITY INVESTIGATIONS BY THE USGS.
Marshall E. Jennings, Timothy L. Miller
Urbonas BenRoesner Larry A., editor(s)
1986, Conference Paper
U. S. Geological Survey (USGS) urban stormwater investigations, in cooperation with local and Federal agencies, have produced significant national data bases of information and enhanced understanding of urban hydrologic processes. Studies in progress include statistical regionalization of urban stormwater quality, the effects of stormwater detention on water quality, ways of...
Inclusion body disease of cranes: Comparison of pathologic findings in cranes with acquired vs. experimentally induced disease
J. C. Schuh, L. Sileo, Lynne M. Siegfried, Thomas M. Yuill
1986, Journal of the American Veterinary Medical Association (189) 993-996
Inclusion body disease of cranes was the cause of death in 17 immature and mature cranes of 5 different species in Wisconsin. A herpesvirus of unknown origin was the apparent cause. An isolate of this herpesvirus was used to experimentally infect 3 species of cranes. Macroscopic and microscopic lesions associated...
Processing techniques for digital sonar images from GLORIA.
P.S. Chavez Jr.
1986, Photogrammetric Engineering and Remote Sensing (52) 1133-1145
Image processing techniques have been developed to handle data from one of the newest members of the remote sensing family of digital imaging systems. This paper discusses software to process data collected by the GLORIA (Geological Long Range Inclined Asdic) sonar imaging system, designed and built by the Institute of...
A numerical investigation of head waves and leaky modes in fluid- filled boreholes
Frederick L. Paillet, C.H. Cheng
1986, Geophysics (51) 1438-1449
Although synthetic borehole seismograms can be computed for a wide range of borehole conditions, the physical nature of shear and compressional head waves in fluid-filled boreholes is poorly understood. This paper presents a series of numerical experiments designed to explain the physical mechanisms controlling head-wave propagation in boreholes. These calculations...
Effects of temperature and sliding rate on frictional strength of granite
D.A. Lockner, R. Summers, J.D. Byerlee
1986, Pure and Applied Geophysics PAGEOPH (124) 445-469
Layers of artificial granite gouge have been deformed on saw-cut granite surfaces inclined 30?? to the sample axes. Samples were deformed at a constant confining pressure of 250 MPa and temperatures of 22 to 845??C. The velocity dependence of the steady-state coefficient of friction (??ss) was determined by comparing sliding...
Ages of igneous and hydrothermal events in the Round Mountain and Manhattan gold districts, Nye County, Nevada
D. R. Shawe, R. F. Marvin, P.A.M. Andriessen, H. H. Mehnert, V.M. Merritt
1986, Economic Geology (81) 388-407
About 60 new isotopic age determinations help clarify the geologic history of the Round Mountain and Manhattan gold districts, Nevada. Cretaceous granite of Shoshone Mountain, southeast of Round Mountain, was emplaced about 95 m.y. ago and was domed, metamorphosed, and mineralized with tungsten-bearing quartz veins 80 m.y. ago. The granite...
Mineralogy and geochemical evolution of the Little Three pegmatite-aplite layered intrusive, Ramona, California
L.A. Stern, Gordon E. Brown Jr., D.K. Bird, R. H. Jahns, E.E. Foord, J.E. Shigley, L.B. Spaulding Jr.
1986, American Mineralogist (71) 406-427
Several layered pegmatite-aplite intrusives exposed at the Little Three mine, Ramona, display closely associated fine-grained to giant-textured mineral assemblages which are believed to have co-evolved from a hydrous aluminosilicate residual melt with an exsolved supercritical vapour phase. Calculations of phase relations between the major pegmatite-aplite mineral assemblages and supercritical aqueous...
LANDSLIDE DAMMED LAKES AT MOUNT ST. HELENS, WASHINGTON.
William Meyer, Martha A. Sabol, Robert Schuster
Schuster Robert L., editor(s)
1986, Conference Paper
The collapse of the north face of Mount St. Helens on May 18, 1980, and the debris avalanche that resulted blocked outflow from Spirit Lake and Coldwater and South Fork Castle Creeks. Spirit Lake began to increase in size and lakes began to form in the canyons of Coldwater and...
The solubility of BaCO3(cr) (witherite) in CO2-H2O solutions between 0 and 90°C, evaluation of the association constants of BaHCO3+(aq) and BaCO30(aq) between 5 and 80°C, and a preliminary evaluation of the thermodynamic properties of Ba2+(aq)
Eurybiades Busenberg, Niel Plummer
1986, Geochimica et Cosmochimica Acta (50) 2225-2233
One hundred and fifty new measurements of the solubility of witherite were used to evaluate the equilibrium constant of the reaction BaCO3(cr) = Ba2+(aq) + CO32−(aq) between 0 and 90°C and 1 atm total pressure. The temperature dependence of the equilibrium constant is given by logK = 607.642 + 0.121098T − 20011.25/T − 236.4948 logT where T is in degrees...
A comparison of upper mantle subcontinental electrical conductivity for North America, Europe, and Asia.
W.H. Campbell, E.R. Schiffmacher
1986, Journal of Geophysics - Zeitschrift fur Geophysik (59) 56-61
Spherical harmonic analysis coefficients of the external and internal parts of the quiet-day geomagnetic field variations (Sq), separated for the N American, European, Central Asian and E Asian regions, were used to determine conductivity profiles to depths of about 600km by the Schmucker equivalent-substitute conductor method. All 3 regions showed...
Avian tuberculosis and salmonellosis in a whooping crane (Grus americana)
R. K. Stroud, C.O. Thoen, R. M. Duncan
1986, Journal of Wildlife Diseases (22) 106-110
The whooping crane has been the subject of intensive scientific study and management because it is an endangered species and has high public interest. Programs have been developed to identify critical habitat, to increase production through captive breeding, and in recent years, to use sandhill cranes (Grus canadensis) as surrogate...
A ground-water mixing model for the origin of the Imini manganese deposit (Cretaceous) of Morocco
E. R. Force, W. Back, E.C. Spiker, L.P. Knauth
1986, Economic Geology (81) 65-79
Three beds of manganese oxide ore in a 10 m-thick dolomite unit are associated with diagenetic features, and, are accordingly also diagenetic in their present aspect. Whether primary or introduced, the Mn mineralogy is attributed to reactions between fresh and saline ground-waters as the zone of mixing passed through the...
Archaeological prospection: An introduction to the Special Issue
Jeffrey C. Wynn
1986, Geophysics (51) 533-537
Archaeological prospection, as the use of geophysical methods in archaeology is known in Europe, is about four decades old (seven decades, if aerial photography of archaeological sites is included). Virtually the entire range of geophysical methods, perhaps excluding only borehole techniques, has found application in the search for archaeological sites...
