Simulated effects of ground-water development on the potentiometric surface of the Floridan aquifer, west-central Florida
W.E. Wilson, J. M. Gerhart
1982, Professional Paper 1217
A digital model of two-dimensional ground-water flow was used to predict changes in the potentiometric surface of the Floridan aquifer, 1976 to 2000, in a 5,938-square-mile area of west-central Florida. In 1975, ground water withdrawn from the Floridan aquifer for irrigation, phosphate mines, other industries, and municipal supplies averaged about...
Effects of soils and grazing on breeding birds of uncultivated upland grasslands of the Northern Great Plains
H.A. Kantrud, R.L. Kologiski
1982, Wildlife Research Report 15
The principal use of uncultivated upland grasslands in the northern Great Plains is for livestock production. However, on lands set aside for wildlife or for scientific or recreational use, grazing by livestock may be used as a management measure to enhance populations of game species or to create conditions that...

Occlusion of the syrinx as a manifestation of aspergillosis in Canada geese
R. K. Stroud, R. M. Duncan
1982, Journal of the American Veterinary Medical Association (181) 1389-1390
Aspergillosis has been described in many species of wild waterfowl, primarily as a disease of the respiratory tract. Typically, mycotic granulomas are found in the lungs. Air sacs may be thickened and contain discoid individual or coalescing greenish or bluish plaques resembling bread mold. Occasionally, there is systemic involvement, with...

Chlamydiosis in 2 biologists investigating disease occurrences in wild waterfowl
Gary Wobeser, Christopher J. Brand
1982, Wildlife Society Bulletin (10) 170-172
Chlamydiosis (ornithosis, psittacosis) is an infectious disease of birds that can be transmitted to humans. Human infections are probably acquired by inhalation of aerosols containing elementary bodies of the causative agent Chlamydia psittaci, from bird droppings, or from tissues. Infected birds do not have to be ill to transmit the...
Earthquake-induced sediment failures on a 0.25o slope, Klamath River delta, California.
M.E. Field, J.V. Gardner, A. E. Jennings, B. D. Edwards
1982, Geology (10) 542-546
On Nov. 8, 1980, a major earthquake (magnitude 6.5-7.2) occurred 60 km off the coast of N California. A survey of the area using high-resolution seismic-reflection and side-scan sonar equipment revealed the presence of extensive sediment failure and flows in a zone about 1 km wide and 20 km long...
Introduction: seismology and earthquake engineering in Mexico and Central and South America.
A. F. Espinosa
1982, Earthquake Information Bulletin (USGS) (14) 4-6
The results from seismological studies that are used by the engineering community are just one of the benefits obtained from research aimed at mitigating the earthquake hazard. In this issue of Earthquake Information Bulletin current programs in seismology and earthquake engineering, seismic networks, future plans and some of the cooperative...
Mineral paragenesis in the talc-water experimental hydrothermal system.
G. Whitney, D. D. Eberl
1982, American Mineralogist (67) 944-949
The talc-like gel was treated between 300o and 550oC at 1 kbar for 7, 30, 50, 120 and 200 days. The trends suggest that stevensite and/or corrensite are the stable minerals at <450oC. At 500o- 550oC, talc is stable.-K.A.R....
Pingos in the Brooks Range, northern Alaska, U.S.A.
T. D. Hamilton, Curtis M. Obi
1982, Arctic and Alpine Research (14) 13-20
Some 70 pingos occur at 27 separate localities within and near the Brooks Range. The pingos are distributed through mountain valleys at altitudes up to 725 m and in terrain glaciated as recently as late Wisconsinan time. Most are open-system forms; possible closed-system pingos are present at only a single...

Determination of lithium isotopes at natural abundance levels by atomic absorption spectrometry
A. L. Meier
1982, Analytical Chemistry (54) 2158-2161
The relationships of the absorption of 6Li and 7Li hollow cathode lamp emissions are used to determine lithium isotopic composition in the natural abundance range of geologic materials. Absorption was found to have a nonlinear dependence upon total lithium concentration and isotopic composition. A method using nonlinear equations to describe...
An equation correlating the solubility of quartz in water from 25° to 900°C at pressures up to 10,000 bars
Robert O. Fournier, Robert W. Potter II
1982, Geochimica et Cosmochimica Acta (46) 1969-1973
The solubility of quartz in water from 25° to 900°C at specific volume of the solvent ranging from about 1 to 10 and from 300° to 600°C at specific volume of the solvent ranging from about 10 to 100 is given by an empirically derived equation of the form: log m = A + B(log V)...
Oxygen isotope evidence for shallow emplacement of Adirondack anorthosite
J.W. Valley, J. R. O’Neil
1982, Nature (300) 497-500
Oxygen isotopic analysis of wollastonites from the Willsboro Mine, Adirondack Mountains, New York reveals a 400-ft wide zone of 18O depletion at anorthosite contacts. Values of ??18O vary more sharply with distance and are lower (to -1.3) than any yet reported for a granulite fades terrain. Exchange with circulating hot...
Exotic terranes of western California
M.O. McWilliams, D. G. Howell
1982, Nature (297) 215-217
Numerous distinct geological terranes compose the North American Cordillera1; there may be as many as 50 terranes in California alone2. Critical to deciphering the history of Cordilleran tectonic assembly is an understanding of the displacement history of individual terranes. It is therefore important to know: (1) whether a terrane has...
Mineralogy and geochemistry of Fe-Ti oxide and apatite (nelsonite) deposits and evaluation of the liquid immiscibility hypothesis.
A. Kolker
1982, Economic Geology (77) 1146-1158
Modal mineralogy determined for 32 Fe-Ti oxide and apatite rocks from localities in Virginia, New York, Quebec, Norway, and Sweden largely supports the 2:1 oxide:apatite ratio suggested as a eutectic mixture by Philpotts (1967). A fairly consistent suite of accessory minerals, including biotite, clinoamphibole, spinel, zircon, and sulfides, is present....
Chemistry and isotope ratios of sulfur in basalts and volcanic gases at Kilauea volcano, Hawaii
H. Sakai, T. J. Casadevall, J.G. Moore
1982, Geochimica et Cosmochimica Acta (46) 729-738
Eighteen basalts and some volcanic gases from the submarine and subaerial parts of Kilauea volcano were analyzed for the concentration and isotope ratios of sulfur. By means of a newly developed technique, sulfide and sulfate sulfur in the basalts were separately but simultaneously determined. The submarine basalt has 700 ±...
A model for managing sources of groundwater pollution
Steven M. Gorelick
1982, Water Resources Research (18) 773-781
The waste disposal capacity of a groundwater system can be maximized while maintaining water quality at specified locations by using a groundwater pollutant source management model that is based upon linear programing and numerical simulation. The decision variables of the management model are solute waste disposal rates at various facilities...

N. D. Naeser, J.A. Westgate, O.L. Hughes, T. L. Pewe
1982, Canadian Journal of Earth Sciences (19) 2167-2178
Six distal tephra beds from the Yukon Territory and Alaska have been dated by the fission-track method. Zircon and glass ages were determined for the Fort Selkirk and Lost Chicken tephra beds, but only glass ages for the others.Assuming that no track fading has occurred in the glass, Old Crow...
Geomagnetic local and regional harmonic analyses
L.R. Alldredge
1982, Journal of Geophysical Research Solid Earth (87) 1921-1926
Procedures are developed for using rectangular and cylindrical harmonic analyses in local and regional areas. Both the linear least squares analysis, applicable when component data are available, and the nonlinear least squares analysis, applicable when only total field data are available, are treated. When component data are available, it is...
