Geochemical evolution of Kohala Volcano, Hawaii
M. A. Lanphere, F.A. Frey
1987, Contributions to Mineralogy and Petrology (95) 100-113
Kohala Volcano, the oldest of five shield volcanoes comprising the island of Hawaii, consists of a basalt shield dominated by tholeiitic basalt, Pololu Volcanics, overlain by alkalic lavas, Hawi Volcanics. In the upper Pololu Volcanics the lavas become more enriched in incompatible elements, and there is a transition from tholeiitic...

Analyzing numerical errors in domain heat transport models using the CVBEM
T. V. Hromadka II
1987, Journal of Offshore Mechanics and Arctic Engineering (109) 163-169
Besides providing an exact solution for steady-state heat conduction processes (Laplace-Poisson equations), the CVBEM (complex variable boundary element method) can be used for the numerical error analysis of domain model solutions. For problems where soil-water phase change latent heat effects dominate the thermal regime, heat transport can be approximately modeled...

Recognition of Macluritella (Gastropoda) from the Upper Cambrian of Missouri and Nevada
E. L. Yochelson, B.L. Stinchcomb
1987, Journal of Paleontology (61) 56-61
Open-coiled euomphalacean gastropods have been identified for the first time in the Upper Cambrian Eminence Dolomite of Missouri. These gastropods have a triangular whorl profile and are conspecific with Hyolithes walcotti described from the Upper Cambrian of Nevada. That species is questionably reassigned to the gastropod genus Macluritella,...
An unusual pleomorphic sarcoma in a hybrid mallard
Thomas J. Roffe
1987, Journal of Wildlife Diseases (23) 334-337
An unusual pleomorphic sarcoma from a hybrid mallard (Anas platyrhynchos) is described. Rhabdomyosarcoma was considered in the original differential diagnoses but rejected due to lack of specific characteristics generally seen in these tumors. The histologic characteristics described are consistent with mammalian sarcomas recorded in the literature as malignant fibrous histiocytoma....
Provenance studies by fission-track dating of zircon-etching and counting procedures
N. D. Naeser, P.K. Zeitler, C. W. Naeser, P.F. Cerveny
1987, International Journal of Radiation Applications and Instrumentation. Part D. Nuclear Tracks and Radiation Measurements (13) 121-126
In sedimentary rocks that have not been heated to high enough temperatures to anneal fission tracks in zircon (greater than ≈ 160°C), fission-track ages of individual detrital zircon grains provide valuable information about the source rocks eroded to form the sediments. The success of such studies depends, however, on the...
Use of tree aggregations in forest ecology and management
N.L. Stephenson
1987, Environmental Management (11) 1-5
Two recent studies using tree aggregations to analyze forest age-structure stability and past forest structure are flawed. A better understanding of aggregation dynamics is needed before aggregation analysis is used in forest management....
Methylation patterns of aquatic humic substances determined by13C NMR spectroscopy
Kevin A. Thorn, C. Steelink, Robert L. Wershaw
1987, Organic Geochemistry (11) 123-137
13C NMR spectroscopy is used to examine the hydroxyl group functionality of a series of humic and fulvic acids from different aquatic environments. Samples first are methylated with13C-labeled diazomethane. The NMR spectra of the diazomethylated samples allow one to distinguish between methyl esters of carboxylic acids, methyl ethers of phenolic...

B. Skipp
1987, Geology (15) 220-224
The Clearwater orogenic zone in central Idaho and western Montana contains at least two major northeast-directed Cordilleran thrust plates of Early Proterozoic metasedimentary and metaigneous rocks that overrode previously folded Middle Proterozoic rocks of the Belt basin in Cretaceous time. The northeastward migration...
Neutron activation determination of iridium, gold, platinum, and silver in geologic samples
Hugh T. Millard Jr.
1987, Journal of Radioanalytical and Nuclear Chemistry Articles (113) 125-132
Low-level methods for the determination of iridium and other noble metals have become increasingly important in recent years due to interest in locating abundance anomalies associated with the Cretaceous and Tertiary (K-T) boundary. Typical iridium anomalies are in the range of 1 to 100 ??g/kg (ppb). Thus methods with detection...
ESTIMATING LOW-FLOW FREQUENCIES OF UNGAGED STREAMS IN NEW ENGLAND.
S. William Wandle Jr.
1987, Conference Paper
Equations to estimate low flows were developed using multiple-regression analysis with a sample of 48 river basins, which were selected from the U. S. Geological Survey's network of gaged river basins in Massachusetts, New Hampshire, Rhode Island, Vermont, and southwestern Maine. Low-flow characteristics are represented by the 7Q2 and 7Q10...

1987, Scanning Micros (1) 503-513
The PIXE (proton-induced X-ray emission) microprobe can be used for nondestructive, in-situ analyses of areas as small as those analyzed by the electron microprobe, and has a sensitivity of detection as much as two orders of magnitude better than the electron microprobe. Preliminary studies demonstrated that PIXE provides a capability...

James L. Bodkin, Glenn R. VanBlaricom, Ronald J. Jameson
1987, Environmental Biology of Fishes (18) 73-76
Observations of three incidents of the mass mortality of nearshore fishes are reported; each corresponded to periods of high-amplitude, long-period swells during the 1982-1983 El Niño event along the coast of central California. Members of the nearshore kelp forest fish assemblage, primarily of the genus Sebastes, accounted for 96%...

R.M. Iverson, J. J. Major
1987, Geological Society of America Bulletin (99) 579-594
Simple ground-water flow analyses can clarify complex empirical relations between rainfall and landslide motion. Here we present detailed data on rainfall, ground-water flow, and repetitive seasonal motion that occurred from 1982 to 1985 at Minor Creek landslide in northwestern California, and we interpret these data in the context of physically...

R. A. Zielinski, R.R. Schumann
1987, Journal of Geochemical Exploration (27) 281-298
Douglas fir trees and associated soils were sampled from the slopes of a small (∼4 km2) drainage basin in northeastern Washington to investigate the biogeochemical response to locally uraniferous groundwater. Uranium is preferentially incorporated in needles and twigs compared to larger...

A. A. Pucci Jr., J.A.E. Murashige
1987, Groundwater (25) 672-678
This article describes the use of kriging for optimizing data collection and utility in a regional ground-water investigation of the Potomac-Raritan-Magothy aquifer system in central New Jersey. Kriging was used to (1) estimate the altitude of an aquifer surface, (2) estimate hydraulic conductivities from point...

1987, Journal of Wildlife Diseases (23) 438-442
During December 1983 and early January 1984, about 200 Canada geese (Branta canadensis) died of lead poisoning at Parker River National Wildlife Refuge on Plum Island, Massachusetts. In an effort to determine the source of lead, 100 bottom samples were taken from a refuge impoundment where much of the mortality/morbidity...
