E. Lynn Usery, Phyllis Altheide, Robin R. P. Deister, David J. Barr
1988, Photogrammetric Engineering and Remote Sensing (54) 1623-1628
A knowledge-based geographic information system (KBGIS) approach which requires development of a rule base for both GIS processing and for the geological engineering application has been implemented. The rule bases are implemented in the Goldworks expert system development shell interfaced to the Earth Resources Data Analysis System (ERDAS) raster-based GIS...
Three decades of geochronologic studies in the New England Appalachians
R. E. Zartman
1988, Geological Society of America Bulletin (100) 1168-1180
Over the past 30 years, both isotope geochronology and plate tectonics grew from infancy into authoritative disciplines in the geological sciences. Previously, mountain systems like the Appalachians had been viewed almost entirely in the context of the classical geosyncline, implying a gradualism in stratigraphic and structural change throughout the orogen....

Short-term trends in sulfate deposition at selected bulk precipitation stations in New York
R.M. Hirsch, N.E. Peters
1988, Atmospheric Environment (22) 1175-1178
Trends in rainfall-adjusted sulfate concentration were assessed for 5-yr subrecords of the 14.5–17 yr of monthly bulk-deposition data from five stations in New York by using the seasonal Kendall test. For the 5-yr subrecord from 1978 to 1982, the trends for the bulk deposition were similar to those for weekly...
Tectonic history of the Syria Planum province of Mars
K. L. Tanaka, P. A. Davis
1988, Journal of Geophysical Research Solid Earth (93) 14893-14917
We attribute most of the development of extensive fractures in the Tharsis region to discrete tectonic provinces within the region, rather than to Tharsis as a single entity. One of these provinces is in Syria Planum. Faults and collapse structures in the Syria Planum tectonic province on Mars are grouped...

M. J. Johnson, C.J. Londquist, Julie Laudon, H. T. Mitten
1988, Water-Resources Investigations Report 87-4281
Groundwater development has resulted in lowered water levels and seawater intrusion in the Pajaro Valley, California. An investigation was undertaken to describe the geohydrology of the groundwater flow system and to evaluate the response of the system to pumping stresses by using a mathematical model. The aquifer system consists of...
Photolysis of rhodamine-WT dye
D. Y. Tai, R. E. Rathbun
1988, Chemosphere (17) 559-573
Photolysis of rhodamine-WT dye under natural sunlight conditions was determined by measuring the loss of fluorescence as a function of time. Rate coefficients at 30° north latitude ranged from 4.77 × 10−2 day−1 for summer to 3.16 × 10−2 day−2 for winter. Experimental coefficients were in good agreement with values calculated using a laboratory-determined...
Compositional evolution of the zoned calcalkaline magma chamber of Mount Mazama, Crater Lake, Oregon
C. R. Bacon, T. H. Druitt
1988, Contributions to Mineralogy and Petrology (98) 224-256
The climactic eruption of Mount Mazama has long been recognized as a classic example of rapid eruption of a substantial fraction of a zoned magma body. Increased knowledge of eruptive history and new chemical analyses of ∼350 wholerock and glass samples of the climactic ejecta, preclimactic rhyodacite flows and...
Hydrocarbon gas in sediment of the Southern Pacific Ocean
K.A. Kvenvolden
1988, Geo-Marine Letters (8) 179-187
Methane, ethane, ethene, propane, and propene are common hydrocarbon gases in near-surface sediment from offshore areas in the southern Pacific Ocean near Papua New Guinea, the Solomon Islands, Vanuatu, Tonga, New Zealand, and Antarctica. Sea floor sites for sampling of sediment were selected on the basis of anomalies in marine...
Retardations in fault creep rates before local moderate earthquakes along the San Andreas fault system, central California
Robert O. Burford
1988, Pure and Applied Geophysics PAGEOPH (126) 499-529
Records of shallow aseismic slip (fault creep) obtained along parts of the San Andreas and Calaveras faults in central California demonstrate that significant changes in creep rates often have been associated with local moderate earthquakes. An immediate postearthquake increase followed by gradual, long-term decay back to a previous background rate...
KAr ages, chemical composition and geothermal significance of cenozoic basalt near the Jordan rift
W. A. Duffield, E.H. McKee, F. El Salem, M. Teimeh
1988, Geothermics (17) 635-644
Late Cenozoic mafic lavas crop out locally along the Jordan rift. Some of these lavas are spatially associated with thermal springs, and this association has prompted some workers to hypothesize that the hot water derives its thermal energy from the shallow, still hot intrusive roots of the volcanic rocks. However,...
Composition of massive sulfide deposits from the sediment-covered floor of Escanaba Trough, Gorda Ridge: implications for depositional processes
Randolph A. Koski, Wayne C. Shanks III, Wendy A. Bohrson, Robert L. Oscarson
1988, Canadian Mineralogist (26 pt 3) 655-673
Massive sulfide deposits with two distinct compositions are spatially related to volcanic edifices that penetrate up to 500 m of turbiditic sediment in Escanaba Trough (ET), southern Gorda Ridge. The mineralogy, metal content, sulfur isotope composition, and hydrocarbon content of massive sulfides from ET reflect the extensive interaction between underlying...
Using exogenous variables in testing for monotonic trends in hydrologic time series
William M. Alley
1988, Water Resources Research (24) 1955-1961
One approach that has been used in performing a nonparametric test for monotonic trend in a hydrologic time series consists of a two-stage analysis. First, a regression equation is estimated for the variable being tested as a function of an exogenous variable. A nonparametric trend test such as...
Dating shorelines of lakes in Patagonia, Argentina
R.W. Galloway, Vera Markgraf, J.P. Bradbury
1988, Journal of South American Earth Sciences (1) 195-198
Organic remains from elevated shorelines of two closed basins were radiocarbon dated and document lakes substantially larger than today between 19,500 and 15,000 years BP in northern Patagonia (lat. 41°S), but only for the last 4000 years in southern Patagonia (lat. 49°S). Such latitudinal difference in the timing of high...

Power formula for open-channel flow resistance
Cheng-lung Chen
1988, Conference Paper
This paper evaluates various power formulas for flow resistance in open channels. Unlike the logarithmic resistance equation that can be theoretically derived either from Prandtl's mixing-length hypothesis or von Karman's similarity hypothesis, the power formula has long had an appearance of empiricism. Nevertheless, the simplicity in the form of the...

1988, Journal of Geophysical Research Solid Earth (93) 13165-13173
The December 29–30, 1985, flow test of the State 2–14 well, also known as the Salton Sea Scientific drill hole, produced fluid from a depth of 1865–1877 m at a reservoir temperature of 305° ± 5°C. Another flow test at a depth of 3170 m produced brine contaminated by drilling...
Geologic evidence for a magma chamber beneath Newberry Volcano, Oregon
N. S. MacLeod, D. R. Sherrod
1988, Journal of Geophysical Research Solid Earth (93) 10067-10079
At Newberry Volcano, central Oregon, more than 0.5 m.y. of magmatic activity, including caldera collapse and renewed caldera-filling volcanism, has created a structural and thermal chimney that channels magma ascent. Holocene rhyolitic eruptions (1) have been confined mainly within the caldera in an area 5 km in diameter, (2) have...
