Quaternary history of some southern and central Rocky Mountain basins
Marith C. Reheis, Robert C. Palmquist, S.S. Agard, Cheryl Jaworowski, Brainerd Mears, Richard F. Madole, Alan R. Nelson, Gerald Osborn
1991, Book chapter, Quaternary nonglacial geology
This chapter summarizes the current state of late Cenozoic stratigraphic knowledge in some Rocky Mountain basins (here defined as the structurally low portions of major drainage basins) that have been studied in...
The Briggs Creek Amphibolite, Klamath Mountains, Oregon: Its origin and dispersal
Robert G. Coleman, Marvin A. Lanphere
1991, New Zealand Journal of Geology and Geophysics (34) 271-284
The Briggs Creek Amphibolite (BCA) in southwestern Oregon is an allochthonous slice of metamorphosed oceanic crust emplaced during the Nevadan orogenic event. Even though the evidence is not clear, the authors prefer to have the protolith for the BCA formed in a back‐arc basin contemporaneously as part of the Josephine...
Great lakes embryo mortality, edema, and deformities syndrome (glemeds) in colonial fish-eating birds: Similarity to chick-edema disease
Michael Gilbertson, Timothy J. Kubiak, James P. Ludwig, Glen Fox
1991, Journal of Toxicology and Environmental Health (33) 455-520
Several species of colonial fish-eating birds nesting in the Great Lakes basin Includ-ing herring gulls, common terns and double-crested cormorants, have exhibited chronic impairment of reproduction. In addition to eggshell thinning caused by high levels of DDT and metabolites, the reproductive impairment is characterized by high embryonic and chick mortality, edema,...
Initiation processes and flow evolution of turbidity currents: Implications for the depositional record
William R. Normark, David J. W. Piper
Robert H. Osborne, editor(s)
1991, Book chapter, From shoreline to abyss: Contributions in marine geology in honor of Francis Parker Shepard
Interpretations of sea-level change and source-area tectonism from the character of turbidite deposits require knowledge of the sediment source, the flow-initiation process, how the turbidity current evolved during flow, and what flow phases were associated with deposition. The flow responds to shape and size characteristics of both the erosional pathway...
Regressive coastal deposits on Quaternary continental shelves: Preservation and legacy
Michael E. Field, Fabio Trincardi
Robert H. Osborne, editor(s)
1991, Book chapter, From shoreline to abyss: Contributions in marine geology in honor of Francis Parker Shepard
Regressive coastal deposits containing internal downlapping surfaces are common on continental shelves of the world. Through theoretical considerations and evaluation of examples from the literature and our own studies in California and Italy, we have examined the conditions that lead both to the formation and preservation of these deposits.Coastal downlapping...
Periphyton accumulation at remote reefs and shoals in Lake Superior
Thomas A. Edsall, Eugene F. Stoermer, John P. Kociolek
1991, Journal of Great Lakes Research (17) 412-418
Observations made from a submarine showed that the bed-rock surfaces at water depths of about 5 to 14 m on Stannard Rock and Superior Shoal in Lake Superior were covered with a dense, fleece-like blanket of periphyton. Examination of the periphyton revealed it consisted primarily of structurally complex, diverse, diatom...
Prey selection for the exotic cladoceran Bythotrephes cederstroemi by selected Lake Erie fishes
Michael T. Bur, David M. Klarer
1991, Journal of Great Lakes Research (17) 85-93
The importance of zooplankton in the diet of yellow perch (Perca flavescens), white perch (Morone americana), walleyes (Stizostedion vitreum vitreum), and white bass (M. chry-sops)was assessed in the central basin of Lake Erie in 1985–1988. Zooplankton were collected by vertical hauls in 1987–1988 and fish with a rock-hopper trawl. Although...
