Age and depositional setting of siliceous sediments in the upper Paleozoic Havallah sequence near Battle Mountain, Nevada; Implications for the paleogeography and structural evolution of the western margin of North America
Benita L. Murchey
David S. Harwood, M. Meghan Miller, editor(s)
1990, Book chapter, Paleozoic and early Mesozoic paleogeographic relations; Sierra Nevada, Klamath Mountains, and related terranes
The upper Paleozoic Havallah sequence of central Nevada is a folded and thrust-faulted association of greenstone, siliceous marine sedimentary rocks, and deep-water clastic rocks. Microfossil assemblages (radiolarians, sponge spicules, and conodonts) are used as tools to unravel the stratigraphy and to interpret the paleoenvironments of the siliceous sedimentary rocks. Nine...
Synthesis of soil-plant correspondence data from twelve wetland studies throughout the United States
C.A. Segelquist, W.L. Slauson, M. L. Scott, Gregor T. Auble
1990, Report
This report synthesizes the information collected for the U.S. Fish and Wildlife Service in a series of 12 studies designed to describe the relation between soils and vegetation in wetlands located in 11 States throughout the United States. Results of the study demonstrated almost complete agreement between hydric soils and...
Monitoring long-term effects of offshore oil and gas development along the Southern California outer continental shelf and slope: Background environmental conditions in the Santa Maria Basin
Jeffrey Hyland, Dane Hardin, E.A. Crecelius, David Drake, Paul A. Montagna, Margarete Steinhauer
1990, Oil and Chemical Pollution (6) 195-240
Potential environmental impacts of materials discharged from oil and gas development and production platforms off the coast of southern California (Santa Maria Basin) are being monitored during an ongoing, long-term (fiveyear) field program. The study combines hypothesis testing of platform effects...
Biostratigraphic, tectonic, and paleogeographic ties between upper Paleozoic volcanic and basinal rocks in the northern Sierra terrane, California, and the Havallah sequence, Nevada
David S. Harwood, Benita L. Murchey
M. Meghan Miller, editor(s)
1990, Book chapter, Paleozoic and early Mesozoic paleogeographic relations; Sierra Nevada, Klamath Mountains, and related terranes
Biostratigraphic data, based mostly on radiolarian assemblages, establish synchronous deposition in the northern Sierra terrane and the Havallah basin beginning in the Late Devonian and extending into the early Late Permian. Lower Mississippian and mid-Permian arc-derived volcaniclastic debris was deposited in parts of the Havallah basin during episodes of arc...
Fire hazards at the urban-wildland interface: what the public expects
Hanna J. Cortner, Philip D. Gardner, Jonathan G. Taylor
1990, Environmental Management (14) 57-62
Urban-wildland issues have become among the most contentious and problematic issues for forest managers. Using data drawn from surveys conducted by the authors and others, this article discusses how public knowledge and perceptions of fire policies and fire hazards change over time, the kinds of policy responses homeowners prefer as...
[Book review] No Woman Tenderfoot by Harriet Kofalk
Mercedes S. Foster
1990, The Wilson Bulletin (102) 562-567
The subject of this biography, identified in the subtitle “Florence Merriam Bailey, Pioneer Naturalist,” was truly a remarkable ornithologist. The bibliography of her writings, included in the book, lists more than 130 articles, a major portion of which were based on her own field work in what was then the...
Seismic imaging of extended crust with emphasis on the western United States
Jill McCarthy, George A. Thompson
R. D. Hatcher Jr., W.A. Thomas, editor(s)
1990, Book chapter, Centennial articles
Understanding of the crust has improved dramatically following the application of seismic reflection and refraction techniques to studies of the deep crust. This is particularly true in areas where the last tectonic event was extensional, such as the Basin and Range province of the western United States and much of...
Desktop mapping for manatee conservation
Ron G. Osborn
1990, Report, Report of the workshop on Geographic Information Systems as an aid to managing habitat for West Indian manatees in Florida and Georgia
No abstract available....
Stratigraphy and tectonics of Paleozoic arc-related rocks of the northernmost Sierra Nevada, California; The eastern Klamath and northern Sierra terranes
Angela S. Jayko
David S. Harwood, M. Meghan Miller, editor(s)
1990, Book chapter, Paleozoic and early Mesozoic paleogeographic relations; Sierra Nevada, Klamath Mountains, and related terranes
The Eastern Klamath and Northern Sierra terranes of northern California consist of Devonian to Jurassic arc-related rocks that structurally and/or stratigraphically overlie Devonian(?) or older complexes that consist of quartzite, quartzofeldspathic sandstone, chert, and mafic and ultramafic rocks. These terranes lie within a regional belt of Paleozoic arc-related rocks that...
Asteroid and comet flux in the neighborhood of Earth
Eugene Merle Shoemaker, Ruth F. Wolfe, Carolyn S. Shoemaker
Virgil L. Sharpton, Peter D. Ward, editor(s)
1990, Book chapter, Global catastrophes in Earth history: An interdisciplinary conference on impacts, volcanism, and mass mortality
Approximately 90 Earth-crossing asteroids had been discovered through September 1989. Discovery is thought to be complete at absolute V magnitude (H) = 13.2 (the magnitude of the brightest known object, diameter ∼8.1...
