Environmental trade-offs of tunnels vs cut-and-cover subways
M. Walton
1978, Underground Space (3) 61-67
Heavy construction projects in cities entail two kinds of cost - internal cost, which can be defined in terms of payments from one set of parties to another, and external cost, which is the cost borne by the community at large as the result of disutilities entailed in construction and...
Lithium in the McDermitt caldera, Nevada and Oregon
Richard K. Glanzman, J. H. McCarthy Jr., James J. Rytuba
1978, Energy (3) 347-353
Anomalously high concentrations of lithium in fluviatile-lacustrine sediments near McDermitt, Nevada, may constitute a potential resource. These sediments are associated with a caldera about 45 km in diameter that is a result of volcanic activity, subsidence and sedimentation chiefly of Miocene age. The sediments originally were vitroclastic and now...
Range charts and no-space graphs
Lucy E. Edwards
1978, Computers & Geosciences (4) 247-255
No-space graphs present one solution to the familiar problem: given data on the occurrence of fossil taxa in separate, well-sampled sections, determine a range chart; that is, a reasonable working hypothesis of the total range in the area in question of each taxon studied. The solution presented here treats only...
Mössbauer spectroscopic investigation of iron species in coal
Gerard V. Smith, Juei-Ho Liu, Mykola Saporoschenko
1978, Fuel (57) 41-45
A series of Herrin No. 6 coal and three coal-derived samples have been examined by Mo??ssbauer spectroscopy. It is established that Mo??ssbauer spectroscopy can be used to identify multiple iron species in a whole coal or an autoclaved char sample without the need to concentrate the minerals to enhance resolution....
The potential source of lead in the Permian Kupferschiefer bed of Europe and some selected Paleozoic mineral deposits in the Federal Republic of Germany
K.H. Wedepohl, M.H. Delevaux, B. R. Doe
1978, Contributions to Mineralogy and Petrology (65) 273-281
New lead isotopic compositions have been measured for Paleozoic bedded and vein ore deposits of Europe by the high precision thermal emission (triple filament) technique. Eleven samples have been analyzed from the Upper Permian Kupferschiefer bed with representatives from Poland to England, three samples from the Middle Devonian Rammelsberg deposit...
Field expectations and the determination of wildcat drilling
Emil D. Attanasi, L. J. Drew
1977, Southern Economic Journal (44) 53-67
There is currently some dissatisfaction with macroeconomic approaches to modeling the supply of domestic crude oil. One problem that has been pointed out is that the estimated supply responses of new discoveries brought about by price increases appear to be unrealistically high. Because data  frequently  used in these models  are...
Application of linear statistical models of earthquake magnitude versus fault length in estimating maximum expectable earthquakes
Robert K. Mark
1977, Geology (5) 464-466
Correlation or linear regression estimates of earthquake magnitude from data on historical magnitude and length of surface rupture should be based upon the correct regression. For example, the regression of magnitude on the logarithm of the length of surface rupture L can be used to estimate magnitude, but the regression of log L on...
Lisburne Group (Mississippian and Pennsylvanian), potential major hydrocarbon objective of Arctic Slope, Alaska
Kenneth J. Bird, Clifton F. Jordan
1977, AAPG Bulletin (61) 1493-1512
The Lisburne Group, a thick carbonate-rock unit of Mississippian and Pennsylvanian age, is one of the most widespread potential reservoir-rock units in northern Alaska. A comprehensive review of the Lisburne in the subsurface of the eastern Arctic Slope indicates attractive reservoir characteristics in a favorable source and migration setting where...
Oxygen and hydrogen isotope compositions as indicators of granite genesis in the New England Batholith, Australia
J. R. O’Neil, S.E. Shaw, R.H. Flood
1977, Contributions to Mineralogy and Petrology (62) 313-328
Oxygen and hydrogen isotope studies of a number of granite suites and mineral separates from the New England Batholith indicate that ??O18 can be used to discriminate the major granite protoliths. The granite suites previously subdivided on the basis of mineralogical and geochemical criteria into S-type (sedimentary) and I-type (igneous)...

G.L. Storm, D.F. Cottam, R.H. Yahner, J.D. Nichols
1977, American Birds (31) 197-203
We applied mark-resight and area-conversion methods to estimate deer abundance at a 2,862-ha area in and surrounding the Gettysburg National Military Park and Eisenhower National Historic Site during 1987-1991. One observer in each of 11 compartments counted marked and unmarked deer during 65-75 minutes at dusk during 3 counts in...
Prolonged retention of methyl mercury by mallard drakes
L.F. Stickel, W. H. Stickel, M. Anne Ross McLane, M. Bruns
1977, Bulletin of Environmental Contamination and Toxicology (18) 393-400
Mallard drakes accumulated mercury rapidly from dietary dosage of methylmercury dicyandiamide and eliminated it slowly, retaining approximately one half at the end of 84 days; no measurable loss occurred between the end of the 7th and 56th days, but loss resumed concurrently with new feather growth, and continued through the...
Effects of tide cycles on habitat selection and habitat partitioning by migrating shorebirds
J. Burger, M.A. Howe, D.C. Hahn, J. Chase
1977, The Auk (94) 743-758
We studied assemblages of feeding shorebirds in three intertidal habitats on the coast of New Jersey during August to document how species segregate spatially both among and within habitats and to determine the effects of tidal cycles on these patterns. The habitats were a sandy beach facing the ocean proper...
Residues of organochlorine pesticides and polychlorinated biphenyls and autopsy data for bald eagles, 1973-74
R. M. Prouty, W. L. Reichel, L. N. Locke, A. A. Belisle, E. Cromartie, T. E. Kaiser, T. G. Lamont, B.M. Mulhern, D. M. Swineford
1977, Pesticides Monitoring Journal (11) 134-137
Thirty-nine bald eagles found sick or dead in 13 States during 1969 and 1970 were analyzed for pesticide residues. Residues of DDE, dieldrin, polychlorinated biphenyls (PCB's), and mercury were detected in all bald eagle carcasses; DDD residues were detected in 38; DDT, heptachlor epoxide, and dichlorobenzophenone (DCBP) were detected less...

D. R. Clark Jr., J.C. Kroll
1977, Journal of Toxicology and Environmental Health (3) 893-901
Adult female free-tailed bats (Tadarida brasiliensis) were collected at Bracken Cave, Texas, and shipped to the Patuxent Wildlife Research Center. Treated mealworms (Tenebrio molitor) containing 107 ppm DDE were fed to 17 bats; five other bats were fed untreated mealworms. After 40 days on dosage, during which one dosed bat...
Comparison of granitic intrusions in the Pelona and Orocopia Schists, southern California
Fred K. Miller, Douglas M. Morton
1977, Journal of Research of the U.S. Geological Survey (5) 643-649
Dating of some small plutons in the San Gabriel and Chocolate Mountains, southern California, yields Miocene K-Ar ages. A single granodiorite pluton that has been segmented by branches of the San Jacinto fault intrudes the Pelona Schist and yields ages of 14.0 to 18.6 million years. Several quartz monzonite plutons...
Simulation of flow from an aquifer to a partially penetrating trench
Stanley A. Leake
1977, Journal of Research of the U.S. Geological Survey (5) 535-540
Construction of the Tennessee-Tombigbee Waterway in northeast Mississippi will involve dewatering as much as 46 m of an unconfined aquifer near the Tennessee Valley divide. Dewatering by trenching is one of the proposed methods. Methods of calculating effects of dewatering by trenching have been heretofore limited to situations where ideal...
Search for seismic forerunners to earthquakes in central California
R. L. Wesson, R. Robinson, C. G. Bufe, W.L. Ellsworth, J. H. Pfluke, J.A. Steppe, L. C. Seekins
1977, Tectonophysics (42) 111-126
The relatively high seismicity of the San Andreas fault zone in central California provides an excellent opportunity to search for seismic forerunners to moderate earthquakes. Analysis of seismic traveltime and earthquake location data has resulted in the identification of two possible seismic forerunners. The first is a period of apparently...
Suspended particulate loads and transports in the nepheloid layer of the abyssal Atlantic Ocean
P.E. Biscaye, S.L. Eittreim
1977, Marine Geology (23) 155-172
Vertical profiles of light scattering from over 1000 L-DGO nephelometer stations in the Atlantic Ocean have been used to calculate mass concentrations of suspended particles based on a calibration from the western North American Basin. From these data are plotted the distributions of particulate concentrations at clear water and in...
Ground-water resources of Cambodia
William Charles Rasmussen, Gary M. Bradford
1977, Water Supply Paper 1608-P
Cambodia (now the Khmer Republic), in tropical, humid southeast Asia, has an area of 175,630 km and a population of about 5 million. The Mekong River, one of the world's largest rivers, flows through Cambodia. Also, the Tonle Sap (Grand Lac), a highly productive fresh-water lake, functions as a huge...
Reconnaissance engineering geology of the Metlakatla area, Annette Island, Alaska, with emphasis on evaluation of earthquakes and other geologic hazards
Lynn A. Yehle
1977, Open-File Report 77-272
A program to study the engineering geology of most larger Alaska coastal communities and to evaluate their earthquake and other geologic hazards was started following the 1964 Alaska earthquake; this report about the Metlakatla area, Annette Island, is a product of that program. Field-study methods were of a reconnaissance nature,...
Ground-water resources and geology of Colquitt County, Georgia
E. A. Zimmerman
1977, Open-File Report 77-56
Limestone beds of Eocene, Oligocene, and lower Miocene age, called the principal artesian aquifer, are the chief source of ground water for Colquitt County. Because streams are small, undependable and relatively inaccessible to most users, ground water is the most important source for increased industrial and agricultural water use. Southeast...
