Partially melted granodiorite and related rocks ejected from Crater Lake caldera, Oregon
Charles R. Bacon
1992, Earth and Environmental Science Transactions of The Royal Society of Edinburgh (83) 27-47
Blocks of medium-grained granodiorite to 4 m, and minor diabase, quartz diorite, granite, aplite and granophyre, are common in ejecta of the ∼6,900 yrBP calderaforming eruption of Mount Mazama. The blocks show degrees of melting from 0–50 vol%. Because very few have adhering juvenile magma, it is thought that the...

Use of remote sensing and GIS to identify Flamingo habitat in the Argentine Altiplano
Susan C. Boyle, Roger M. Hoffer, Terence P. Boyle, Enrique H. Bucher
1992, Bulletin of the Ecological Society of America (73)
The Argentine altiplano is a remote area which has never been adequately mapped. It is an arid region with harsh climate, little vegetation, sparse population, and an average elevation of over 3,500 feet. Little is known about the large populations of three species of flamingos which nest and...
Variations in the reflectivity of the moho transition zone beneath the Midcontinent Rift System of North America: results from true amplitude analysis of GLIMPCE data
Deborah R. Hutchinson, Myung W. Lee, John C. Behrendt, William F. Cannon, Adrian G. Mann
1992, Journal of Geophysical Research B: Solid Earth (97) 4721-4737
True amplitude processing of The Great Lakes International Multidisciplinary Program on Crustal Evolution seismic reflection data from the Midcontinent Rift System of North America shows large differences in the reflectivity of the Moho transition zone beneath the axial rift, beneath the rift flanks, and outside of the rift. The Moho...
Source region of a granite batholith: Evidence from lower crustal xenoliths and inherited accessory minerals
Calvin F. Miller, John M. Hanchar, Joseph L. Wooden, Victoria C. Bennett, T. Mark Harrison, David A. Wark, David A. Foster
1992, Earth and Environmental Science Transactions of The Royal Society of Edinburgh (83) 49-62
Like many granites, the Late Cretaceous intrusives of the eastern Mojave Desert, California, have heretofore provided useful but poorly focused images of their source regions. New studies of lower crustal xenoliths and inherited accessory minerals are sharpening these images.Xenoliths in Tertiary dykes in this region are the residues of an...

Calibration of the latest Eocene-Oligocene geomagnetic polarity time scale using 40 Ar/ 39 Ar dated ignimbrites
W. C. McIntosh, J. W. Geissman, C.E. Chapin, Michael J. Kunk, Christopher D. Henry
1992, Geology (20) 459-463
A discontinuous record of late Eocene-Oligocene geomagnetic polarity has been determined using high-precision (±<0.15 m.y.) 40Ar/39Ar sanidine dating and a paleomagnetic study of 37-27 Ma ignimbrites in New Mexico, Colorado, and Texas. This record provides age control for several geomagnetic polarity reversals that occurred during three periods of intense ignimbrite volcanism:...

Contribution of fish community metrics to the index of biotic integrity in two Ozark rivers
Nancy J. Hoefs, Terence P. Boyle
1992, Ecological Indicators (1) 283-303
Flow regime, energy source, water quality, and habitat structure within stream systems play major roles in controlling the structure of resident fish communities (Gorman and Karr, 1978; Karr and Dudley, 1981; Schlosser, 1982). Based on the hypothesis that there are predictable relationships between stream variables and fish community structure, overall...

Growth of grain contacts in halite by solution-transfer: Implications for diagenesis, lithification, and strength recovery
Stephen H. Hickman, Brian Evans
1992, International Geophysics (51) 253-280
Lithification of a sediment to form a rock may involve cementation, diagenetic reactions, or compaction under load. In these experiments, convex halite lenses were pressed against fiat halite plates at 50° C in a specially designed microscope stage. A saturated brine...

A reassessment of the role of tidal dispersion in estuaries and bays
W. Rockwell Geyer, Richard P. Signell
1992, Estuaries (15) 97-108
The role of tidal dispersion is reassessed, based on a consideration of the relevant physical mechanisms, particularly those elucidated by numerical simulations of tide-induced dispersion. It appears that the principal influence of tidal currents on dispersion occurs at length scales of the tidal excursion and smaller; thus the effectiveness of...
