Hydrothermal alteration patterns in the Breitenbush Hot Springs area, Cascade Range, Oregon
Terry E.C. Keith
1988, Conference Paper, Transactions - Geothermal Resources Council
Rocks of early Miocene age in the Breitenbush Hot Springs area have been affected by at least two major episodes of hydrothermal alteration, one of which had temperatures in excess of 200??C. Alteration minerals in younger Tertiary rocks are characteristic of temperatures below 100??C. The most important factor in controlling...
Crustal contributions to arc magmatism in the Andes of Central Chile
W. Hildreth, S. Moorbath
1988, Contributions to Mineralogy and Petrology (98) 455-489
Fifteen andesite-dacite stratovolcanoes on the volcanic front of a single segment of the Andean arc show along-arc changes in isotopic and elemental ratios that demonstrate large crustal contributions to magma genesis. All 15 centers lie 90 km above the Benioff zone and 280??20 km from the trench axis. Rate and...
The solubility of noble gases in crude oil at 25-100°C
Yousif K. Kharaka, Daniel J. Specht
1988, Applied Geochemistry (3) 137-144
The solubility of the noble gases He, Ne, Ar, Kr and Xe was measured in two typical crude oils at temperatures of 25–100°C. The oil samples were obtained from the Elk Hills oil field located in southern San Joaquin Valley, California. The experimental procedure consisted of placing a known amount...

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...

J.F. Downhower, editor(s)
1988, Book chapter, The biogeography of the island region of western Lake Erie
The fisheries scientist working in the island region of Lake Erie has access to an extremely large and diverse freshwater fish community. It is the intention of this essay to discuss briefly that community and the impacts of human activities to provide future students and researchers with both current and...

Residues of benzocaine in rainbow trout, largemouth bass, and fish meal
J. L. Allen
1988, Progressive Fish-Culturist (50) 59-60
Residues of the anesthetic benzocaine in muscle tissue of rainbow trout (Salmo gairdneri) and largemouth bass (Micropterus salmoides) were determined after exposure of the fish to 50 mg benzocaine/L for 15 min and withdrawal times of 0–24 h. The mean concentration of benzocaine residues in fish sampled immediately after exposure...
Seasonal growth of the exotic submersed macrophyte Nitellopsis obtusa in the Detroit River of the Great Lakes
S. Jerrine Nichols, Donald W. Schloesser, James W. Geis
1988, Canadian Journal of Botany (66) 116-118
Seasonal growth and occurrence of an exotic submersed aquatic macrophyte, Nitellopsis obtusa, was monitored at the head of the Detroit River of the Great Lakes from June 1984 to April 1985.Nitellopsis obtusa first appeared in early July, increased in biomass from July to September, remained at relatively high biomass from September to...

Optimum protease exposure time for removing adhesiveness of walleye eggs
W. F. Krise
1988, Progressive Fish-Culturist (50) 126-127
Increasing concentrations of protease solution reduce the treatment time required for removal of the adhesive layer surrounding eggs of the walleye (Stizostedion vitreum). When concentrations were increased from 0.01 to 0.1%, treatment time decreased from 30 to 5 min; however, treatment with a 1.0% solution for more than 1 min...

1988, Book chapter, Waterfowl in winter
Foods consumed by canvasback ducks (Aythya valisineria), food availability, and energetic relationships were studied on Navigation Pool 7 of the upper Mississippi River in 1978, 1979, and 1980. Canvasbacks fed primarily upon winter buds of American wildcelery (Vallisneria americana) and tubers of stiff arrowhead (Sagittaria rigida). In 1980, waterfowl consumed...

Several epigenetic mineral deposits in the Ca1rolina slate belt are intimately related to meteoric-hydrothermal systems of late Precambrian and early Paleozoic age. At Pilot Mountain, low 18 O rocks correlate well with zones of strong silicic alteration and alkali leaching accompanied by high alumina minerals (sericite, pyrophyllite, andalusite + or - topaz)...
