Estimating pore and cement volumes in thin section
R. B. Halley
1978, Journal of Sedimentary Petrology (48) 642-650
Point count estimates of pore, grain and cement volumes from thin sections are inaccurate, often by more than 100 percent, even though they may be surprisingly precise (reproducibility + or - 3 percent). Errors are produced by: 1) inclusion of submicroscopic pore space within solid volume and 2) edge effects...
Estimation of the size of a closed population when capture probabilities vary among animals
K.P. Burnham, W.S. Overton
1978, Biometrika (65) 625-633
A model which allows capture probabilities to vary by individuals is introduced for multiple recapture studies n closed populations. The set of individual capture probabilities is modelled as a random sample from an arbitrary probability distribution over the unit interval. We show that the capture frequencies are a sufficient statistic....

James D. Vine
1978, Energy (3) 299-304
The U.S. Geological Survey has responsibility in the U.S. Department of the Interior to assess the nation's energy and mineral resources. The evaluation of reserves and resources of a commodity such as lithium should be a continuing process in the light of advancing technology and ever-growing knowledge of its...
Paleomagnetic results from the Lassiter Coast, Antarctica, and a test for oroclinal bending of the Antarctic Peninsula
Karl S. Kellogg, Richard L. Reynolds
1978, Journal of Geophysical Research B: Solid Earth (83) 2293-2299
Paleomagnetic results from 17 magnetically stable units of Upper Cretaceous (‘Andean’) plutons and dikes of the Lassiter Coast, on the southern Antarctic Peninsula, define a mean paleomagnetic pole at 87°S, 131°W (α95 = 11.5°). This indicates that little latitudinal movement of the southern Antarctic Peninsula has occurred during the past 100...

Katherine Fitzpatrick-Lins
1978, Journal of Research of the U.S. Geological Survey (6) 339-346
Land use change maps prepared from high-resolution, high-altitude aerial photographs for the period 1970 to 1972 of the CARETS (Central Atlantic Regional Ecological Test Site) project were analyzed for accuracy. To test for errors of commission, all outlined areas (polygons) of land use change on five l:100000-scale maps were examined...
Studies of hydroxyaluminum complexes in aqueous solution
J. L. Bersillon, D. W. Brown, Francois Fiessinger, J. D. Hem
1978, Journal of Research of the U.S. Geological Survey (6) 325-337
The coagulating ability of partly neutralized AlCl3 solutions used in water treatment depends on their basicity, expressed here as the ratio NaOH/AlC3. This work presents an identification of the aluminum species active in the coagulation process. The results give rise to an interpretative model which is consistent with those models...

Edward Riley Cox
1978, Journal of Research of the U.S. Geological Survey (6) 319-324
High dissolved-iron concentrations have been noted in water in wells used to monitor effluent that percolates from wastewater disposal lagoons near Old Faithful in Yellowstone National Park. The concentration of dissolved iron in water in a well increased from 80 μg/L (micrograms per liter) before a nearby lagoon was .used...
Relationship between hydrology and bottomland vegetation in the Ozark Mountains of Missouri
E. J. Harvey, John Skelton
1978, Journal of Research of the U.S. Geological Survey (6) 299-305
The identification of plants and plant assemblages that are common to stream reaches that gain water and those that do not is an important key in the study of limestone hydrology. In the Ozark Mountains of Missouri, a rapid change from a stream-channel growth of abundant willows (Salix spp.), touch-me-nots...
Infiltration from tributary streams in the Susquehanna River basin, New York
Allan D. Randall
1978, Journal of Research of the U.S. Geological Survey (6) 285-297
As tributary streams in the Susquehanna River basin leave narrow upland valleys and enter larger valleys floored with permeable stratified glacial drift, they lose water by infiltration through streambeds. The infiltration rate is generally slow near the point of entering a larger valley, but farther downstream it is much faster...

R. Ernest Anderson
1978, Journal of Research of the U.S. Geological Survey (6) 409-424
Chemical variations of 27 rocks that erupted from in and near the Eldorado Mountains, southern Nevada, show (1) fair to good correlation suggestive of a cogenetic suite, (2) a range of uncorrected silica values from about 48 to 74 weight percent with no strong tendency toward bimodality, (3) a calc-alkaline...
Pleistocene history of volcanism and the Owens River near Little Lake, California
Wendell A. Duffield, George I. Smith
1978, Journal of Research of the U.S. Geological Survey (6) 395-408
During pluvial periods of the Pleistocene and Holocene, a large river flowed south from Owens Lake to China Lake between the Sierra Nevada and the Coso Range. The most recent channel, dry during historic time, is clearly marked by cliffs and falls. An older, now-abandoned part of the channel beneath...
Time relation of the Watchung Basalt flows to the faulting in the Newark Graben
George T. Faust
1978, Journal of Research of the U.S. Geological Survey (6) 391-394
In graben structures, volcanic eruptions and faulting are seldom simultaneous and often are not localized in the same place. Field studies in the Triassic basin of New Jersey have supplied evidence supporting the nonsimultaneity of volcanism and faulting in the Newark graben....
Dating Quaternary faults in the southwestern United States by using buried calcic paleosols
Michael N. Machette
1978, Journal of Research of the U.S. Geological Survey (6) 369-381
Calcareous soils are widespread on upper Pliocene to upper Pleistocene unconsolidated surflcial deposits in semiarid portions of the southwestern United States. Where these soils are related to faults, the soils may provide a means for quantitatively estimating timing and amounts of Quaternary faulting. Soil age estimates are based on the...
Structural control of the Cumberland River and its ancestral channels at Flat Lick, Kentucky
Wayne L. Newell, Dudley D. Rice
1978, Journal of Research of the U.S. Geological Survey (6) 359-367
Remnants of old alluvium on bedrock benches, as much as 76 in (250 ft) above the present course of the Cumberland River near Flat Lick, Ky., are associated with meander scars and broad valleys now occupied by underflt streams. The distribution of old alluvium and associated topographic features define two...
Trenches across the 1906 trace of the San Andreas Fault in northern San Mateo County, California
M. G. Bonilla, J. N. Alt, L. D. Hodgen
1978, Journal of Research of the U.S. Geological Survey (6) 347-358
Two trenches were excavated across the 1906 trace of the San Andreas fault near fences that were displaced by the 1906 faulting. About 18 displacements equal to the 1906 displacement would account for the offset of a stream adjacent to one of the trenches. Review of divergent reports on the...
Aleuts, sea otters, and alternate stable state communities
C.A. Simenstad, J. A. Estes, K.W. Kenyon
1978, Science (200) 403-411
Reexamination of stratified faunal components of a prehistoric Aleut midden excavated on Amchitka Island, Alaska, indicates that Aleut prey items changed dramatically during 2500 years of aboriginal occupation. Recent ecological studies in the Aleutian Islands have shown the concurrent existence of two alternate stable nearshore communities, one dominated by macroalgae,...

Avian cholera in eider ducks in Maine
Carl E. Korschgen, Harold C. Gibbs, H. L. Mendall
1978, Journal of Wildlife Diseases (14) 254-258
Outbreaks of avian cholera (Pasteurella multocida) occur frequently in common eiders (Somateria mollissima dresseri) in Maine during early summer. Studies over a seven year period show that over 90% of the loss occurred in incubating females and might be associated with their weakened condition because females and might be associated...
