Geochemical controls of vanadium accumulation in fossil fuels
G. N. Breit, R. B. Wanty
1989, Conference Paper, American Chemical Society, Division of Petroleum Chemistry, Preprints
High vanadium contents in petroleum and other fossil fuels have been attributed to organic-matter type, organisms, volcanic emanations, diffusion of sea water, and epigenetic enrichment. However, these factors are inadequate to account for the high abundance of vanadium in some fossil fuels and the paucity in others. By examining vanadium...
Prescribed burning guidelines in the Northern Great Plains
Kenneth F. Higgins, James L. Piehl, Arnold D. Kruse
1989, Report
The use of fire to manage grasslands for wildlife is a relatively new management option for resource managers in the Northern Great Plains (NGP). Nearly all of the burning during the past 20-25 years has been conducted without the aid of specific guidelines for the region. This state-of-the-art set of...
River Valley pluton, Ontario: A late-Archean/early-Proterozoic anorthositic intrusion in the Grenville Province
L.D. Ashwal, J. L. Wooden
1989, Geochimica et Cosmochimica Acta (53) 633-641
The River Valley pluton is a ca. 100 km2 body of anorthositic and gabbroic rocks located about 50 km northeast of Sudbury, Ontario. The pluton is situated entirely within the Grenville Province, but its western margin is a series of imbricate thrust faults associated with the Grenville Front Tectonic Zone. It is...
Accounting for intracell flow in models with emphasis on water table recharge and stream-aquifer interaction: 2. A procedure
Donald G. Jorgensen, Donald C. Signor, Jeffrey L. Imes
1989, Water Resources Research (25) 677-684
Intercepted intracell flow, especially if cell includes water table recharge and a stream ((sink), can result in significant model error if not accounted for. A procedure utilizing net flow per cell (Fn) that accounts for intercepted intracell flow can be used for both steady state and transient simulations. Germane to...
Annotated bibliography of fire literature relative to northern grasslands in south-central Canada and north-central United States
Kenneth F. Higgins, David P. Fellows, J. Mike Callow, Arnold D. Kruse, James L. Piehl
1989, Circular 762
Natural resource managers have greatly increased the use of fire to manage grassland habitats during the past two decades in the northern Great Plains region of the United States and Canada. In support of these efforts, we have compiled this annotated bibliography to provide a condensed reference of fire literature...

Gerald W. Garner, Steven C. Amstrup, David C. Douglas, Craig L. Gardner
Charles J. Amlaner Jr., editor(s)
1989, Conference Paper, Biotelemetry X: Proceedings of the 10th international symposium on biotelemetry
Satellite telemetry technology has been used during field studies of polar bears in Alaska since 1985. A total of 109 Platform Transmitter Terminals (PTT) have been deployed on free-ranging female polar bears that seasonally inhabit waters adjacent to the Alaskan coast. The PTTs transmitted locational and sensor data to TIROS-N...
Accelerator 14C dates for early upper paleolithic (basal Aurignacian) at El Castillo Cave (Spain)
V.C. Valdes, J. L. Bischoff
1989, Journal of Archaeological Science (16) 577-584
Three fragments of charcoal taken from different parts of the lowermost bed containing Aurignacian artifacts at El Castillo Cave yielded AMS dates of 37·7 (± 1·8) ka bp, 38·5 (± 1·8) ka bp, and 40·0 (± 2·1) ka bp (average 38·7 ± 1·9 ka bp). These dates are almost identical...
Non-energy minerals and surficial geology of the continental margin of Maryland
R.T. Kerhin
1989, Marine Geology (90) 95-102
The surficial sediments have been mapped and the shallow geologic framework outlined of the Maryland inner continental shelf. The initial study encompassed a small area offshore of Assateague Island but was extended northward to include the Ocean City area and eastward...
Late Quaternary lacustrine paleoenvironments in the Cuenca de México
J.P. Bradbury
1989, Quaternary Science Reviews (8) 75-100
A late Quaternary paleolimnological history from the Mexican highlands has been obtained by diatom analysis of short cores and stratigraphic sections of lake and marsh sediments from the Cuenca de México, the large, endorheic, graben basin that holds Mexico City. The records, dated by radiocarbon and tephrochronologic methods, extend...
Studies of angiospermous wood in Australian brown coal by nuclear magnetic resonance and analytical pyrolysis: New insights into the early coalification process
Patrick G. Hatcher, M. A. Wilson, A. M. Vassallo, H. E. Lerch III
1989, International Journal of Coal Geology (13) 99-126
Many Tertiary coals contain abundant fossilized remains of angiosperms, which commonly dominated the ancient peat-swamp environments; modern analogs of such swamps can be found in tropical and subtropical regions of the world. Comparisons of angiospermous wood from Australian brown coal with...
Short note; Detectability levels for central induction transient soundings
David V. Fitterman
1989, Geophysics (54) 127-129
A question usually asked during the planning of a transient sounding survey is, "Can information useful to solving the geologic problem at hand be obtained from the measurements?" This question is usually answered by constructing a geologic model for the survey area based upon the best available information to determine...
Physical and chemical characteristics of a metal-contaminated overbank deposit, west-central South Dakota, USA
D. C. Marron
1989, Earth Surface Processes and Landforms (14) 419-432
The deposit along the Belle Fourche River is typically up to 2 m thick and extends about 90 m away from the channel along the insides of meander bends. The sediments contain above-background levels of copper, iron, manganese, zinc, and particularly arsenic. An influx at high streamflow of uncontaminated sediment...
Use of a new high-speed digital data acquisition system in airborne ice-sounding
David L. Wright, Jerry A. Bradley, Steven M. Hodge
1989, IEEE Transactions on Geoscience and Remote Sensing (27) 561-567
A high-speed digital data acquisition and signal averaging system for borehole, surface, and airborne radio-frequency geophysical measurements was designed and built by the US Geological Survey. The system permits signal averaging at rates high enough to achieve significant signal-to-noise enhancement in profiling, even in airborne applications. The first field use...
Influence of coupling of sorption and photosynthetic processes on trace element cycles in natural waters
C. C. Fuller, J.A. Davis
1989, Nature (340) 52-57
Chemical and biological processes have important roles in the transport and cycling of trace elements in natural waters, but their complex interactions are often not well understood. Trace-element concentrations may, for example, be controlled by adsorption-desorption reactions at mineral surfaces, with the equilibrium strongly influenced by pH. Variations in pH...

L.S. Weissleader, N.L. Gilinsky, R. M. Ross, T. M. Cronin
1989, Journal of Biogeography (16) 103-114
Shallow-water podocopic marine Ostracoda from Micronesian lagoons in the Marianas, Caroline, Marshall and Gilbert Islands in the western Pacific were analysed to establish their diversity and zoogeography within Micronesia and the taxonomic affinities with ostracodes from other tropical regions. Sixty-four bottom lagoonal sediment samples from twelve islands and atolls yielded...

Frank J. Triska, Vance C. Kennedy, Ronald J. Avanzino, Gary W. Zellweger, Kenneth E. Bencala
1989, Ecology (70) 1877-1892
Chloride was injected as a conservative tracer with nitrate to examine nitrate retention (storage plus biotic uptake) and transport in a 327—m reach of a third—order stream draining a forested basin in northwestern California. Prior to injections, diel patterns of nutrient concentrations were measured under background conditions. Nitrate concentration of...
