Frictional strength and the effective pressure law of montmorillonite and illite clays
C. Morrow, B. Radney, J. Byerlee
1992, International Geophysics (51) 69-88
Low-strength clay minerals are a common constituent of fault gouges, and are often cited as a possible explanation for the low ambient shear stresses along the San Andreas fault inferred from heat flow constraints and in situ stress measurements. Montmorillonite, the weakest of the clay minerals, undergoes a gradual phase...

SeaMARC II mapping of transform faults in the Cayman Trough, Caribbean Sea
Eric Rosencrantz, Paul Mann
1992, Geology (19) 690-693
SeaMARC II maps of the southern wall of the Cayman Trough between Honduras and Jamaica show zones of continuous, well-defined fault lineaments adjacent and parallel to the wall, both to the east and west of the Cayman spreading axis. These lineaments mark the present, active traces of transform faults which...

Observations of quasistatic fault growth from acoustic emissions
David A. Lockner, J.D. Byerlee, V. Kuksenko, A. Ponomarev, A. Sidorin
1992, International Geophysics (51) 3-31
The location of acoustic emission (AE) sources during deformation of rock has proven to be a useful non-destructive analytic technique. We present experimental results,based on AE observations, that show the nucleation and growth of macroscopic fault planes in granite and sandstone samples. By controlling axial stress to maintain constant...

Baerbel K. Lucchitta, A. S. McEwen, Gary D. Clow, Paul E. Geissler, R.B. Singer, R. A. Schultz, Steven W. Squyres
1992, Book chapter, Mars
Individual Martian equatorial troughs are described, and their stratigraphy, geomorphology and structure are discussed. Possible origins and the overall sequence of events are addressed. Wall rock, interior layered deposits, irregular floor deposits, fractured floor material, and surficial deposits are examined. Chasma walls, wall stability, pits and pit chains, tributary canyons,...

Miocene intensification of upwelling along the California margin as recorded in siliceous facies of the Monterey Formation and offshore DSDP sites
Lisa D. White, Robert E. Garrison, John A. Barron
C. P. Summerhayes, W.L. Prell, K.C. Emeis, editor(s)
1992, Book chapter, Upwelling systems: Evolution Since the early Miocene
Diatomaceous sediments and their diagenetic equivalents in the Monterey Formation record a variable history of upwelling along the California margin. Distrinctive dark opal-CT and quartz chertz found in distal basins of the Monterey Formation are the result of burial diagenesis of pure biosiliceous oozes (biosiliceous oozes without significant admixtures of...

Human disturbances of waterfowl: causes, effects, and management
C. E. Korschgen, R.B. Dahlgren
1992, Fish and Wildlife Leaflet 13.2.15
Human disturbances of waterfowl can be intentional or unintentional. They may result from overt or directed activities or may be ancillary to activities not initially thought to be of concern to birds. Some of these disturbances are manifested by alertness, fright (obvious or inapparent), flight, swimming, disablement, or death. Therefore,...

Effect of pH on the toxicity of TFM to sea lamprey larvae and nontarget species during a stream treatment
T.D. Bills, D.A. Johnson
1992, Technical Report 57
Treatment of tributaries to the Great Lakes with the lampricide 3-trifluoromethyl-4-nitrophenol (TFM) occasionally results in incomplete kills of sea lamprey larvae (Petromyzon marinus ) or excessive mortality of nontarget fish. In continuous-flow toxicity tests conducted on the Millecoquins River, Michigan, TFM remained selective for sea lamprey at...
Human disturbances of waterfowl: An annotated bibliography
R.B. Dahlgren, C. E. Korschgen
1992, Resource Publication 188
The expansion of outdoor recreation greatly increased the interaction between the public, waterfowl, and waterfowl habitat. The effects of these interactions on waterfowl habitats are visible and obvious, whereas the effects of interactions that disrupt the normal behavior of waterfowl are subtle and often overlooked, but perhaps...
Effects of the lampricide 3-trifluoromethyl-4-nitrophenol on dissolved oxygen in aquatic systems
V. K. Dawson, D.A. Johnson, J.F. Sullivan
1992, Technical Report 57
The effects of the lampricide 3-trifluoromethyl-4-nitrophenol (TFM) on dissolved oxygen and other water- quality characteristics were evaluated in a series of test chambers under selected combinations of water, sediment, TFM, and exposure to sunlight. Concentrations of TFM gradually decreased over time, especially in the presence of sediment and...

Net photosynthesis (Pn), dark respiration (Rd), transpirational flux density (TFD) and leaf conductance (kl) on glasshouse-grown plants of almond, apple, fig, grape, olive, peach and Asian pear were examined under various laboratory environmental conditions. Grape and almond had the highest light-saturated photosynthetic rates, greater than 20 μmol CO2 m−2 s−1. Apple had...

1992, American Mineralogist (77) 1021-1030
Rare melt inclusions ~ 100 μm in diameter trapped near the boundaries of corroded patchy zones in plagioclase phenocrysts from Plinian pumice of three Holocene eruptions were analyzed by IR spectroscopy for molecular H2O, OH groups, and CO2and by electron microprobe for Cl and F. The three rhyodacitic eruptions, each of...
