Origin of gasoline-range hydrocarbons and their migration by solution in carbon dioxide in Norton basin, Alaska.
Keith A. Kvenvolden, George E. Claypool
1980, American Association of Petroleum Geologists Bulletin (64) 1078-1086
Carbon dioxide from a submarine seep in Norton Sound, Alaska, carries a minor component of gas- and gasoline-range hydrocarbons. The molecular and isotopic compositions of the hydrocarbon gases and the presence of gasoline-range hydrocarbons indicate that these molecules are derived from thermal alteration of marine and/or nonmarine organic matter buried...
Evaluation of multispectral middle infrared aircraft images for lithologic mapping in the East Tintic Mountains, Utah
A.B. Kahle, L. C. Rowan
1980, Geology (8) 234-239
Six channels of multispectral middle infrared (8 to 14 μrn) aircraft scanner data were acquired over the East Tintic mining district, Utah. This area has high relief and moderate vegetation and consists mainly of Tertiary silicic igneous rocks and Paleozoic quartzite and carbonate...
Gas and hydrogen isotopic analyses of volcanic eruption clouds in Guatemala sampled by aircraft
W.I. Rose Jr., R.D. Cadle, L.E. Heidt, I. Friedman, A.L. Lazrus, B.J. Huebert
1980, Journal of Volcanology and Geothermal Research (7) 1-10
Gas samples were collected by aircraft entering volcanic eruption clouds of three Guatemalan volcanoes. Gas chromatographic analyses show higher H2 and S gas contents in ash eruption clouds and lower H2 and S gases in vaporous gas plumes. H isotopic data demonstrate lighter isotopic distribution of water vapor in ash...
Declination and inclination errors in experimentally deposited specularite-bearing sand
S.L. Bressler, D. P. Elston
1980, Earth and Planetary Science Letters (48) 227-232
Naturally disaggregated specularite-bearing sandstone from the Triassic Moenkopi Formation, artificially deposited in controlled magnetic fields of ∼5 × 10−2 mT, acquires a stable remanent magnetization that has systematic errors in inclination and declination. Inclinations about 12° shallower than the applied fields are...
A lead isotope study of mineralization in the Saudi Arabian Shield
J. S. Stacey, B. R. Doe, R. J. Roberts, M.H. Delevaux, J. W. Gramlich
1980, Contributions to Mineralogy and Petrology (74) 175-188
New lead isotope data are presented for some late Precambrian and early Paleozoic vein and massive sulfide deposits in the Arabian Shield. Using the Stacey Kramers (1975) model for lead isotope evolution, isochron model ages range between 720 m.y. and 420 m.y. Most of the massive sulfide deposits in the...
U-Pb ages of uraniferous opals and implications for the history of beryllium, fluorine, and uranium mineralization at Spor Mountain, Utah
K.R. Ludwig, D. A. Lindsey, R. A. Zielinski, K. R. Simmons
1980, Earth and Planetary Science Letters (46) 221-232
The U-Pb isotope systematics of uraniferous opals from Spor Mountain, Utah, were investigated to determine the suitability of such material for geochronologic purposes, and to estimate the timing of uranium and associated beryllium and fluorine mineralization. The results indicate that uraniferous...
Asymmetric measures of association, closed data, and multivariate analysis
M. Hohn, E.B. Nuhfer
1980, Journal of the International Association for Mathematical Geology (12) 235-246
The association between constant-sum variables Xiand Xjexpressed as percentages can be calculated as a product-moment correlation between Xiand Xj/(100 - Xi) and a correlation between Xjand Xi/(100 - Xj). An asymmetric, square matrix may be formed from these coefficients, and multivariate analysis performed by two methods: singular value decomposition and...
Geothermal system at 21°N, East Pacific Rise: physical limits on geothermal fluid and role of adiabatic expansion
J. L. Bischoff
1980, Science (207) 1465-1469
Pressure-volume-temperature relations for water at the depth of the magma chamber at 21°N on the East Pacific Rise suggest that the maximum subsurface temperature of the geothermal fluid is about 420°C. Both the chemistry of the discharging fluid and thermal balance considerations indicate that the effective water/rock ratios in the...
An econometric model of the U.S. secondary copper industry: Recycling versus disposal
M.E. Slade
1980, Journal of Environmental Economics and Management (7) 123-141
In this paper, a theoretical model of secondary recovery is developed that integrates microeconomic theories of production and cost with a dynamic model of scrap generation and accumulation. The model equations are estimated for the U.S. secondary copper industry and used to assess the impacts that various policies and future...
Heat flow and energetics of the San Andreas fault zone
A.H. Lachenbruch, J.H. Sass
1980, Journal of Geophysical Research Solid Earth (85) 6185-6223
Approximately 100 heat flow measurements in the San Andreas fault zone indicate (1) there is no evidence for local factional heating of the main fault trace at any latitude over a 1000-km length from Cape Mendocino to San Bernardino, (2) average heat flow is high (∼2 HFU, ∼80 mW m−2)...

Thickness change involved in the peat-to- coal transformation for a bituminous coal of Cretaceous age in central Utah
Thomas A. Ryer, A.W. Langer
1980, Journal of Sedimentary Petrology (50) 987-992
The ratio of the thicknesses of a layer of peat and the coal bed formed from that peat has been calculated for a bituminous coal bed in central Utah. The method used involves comparison of the thickness of peat eroded by a laterally...
Effect of leaching on apparent digestion coefficients of feedstuffs for salmonids
R. R. Smith, M. C. Peterson, A. C. Allred
1980, Progressive Fish-Culturist (42) 195-199
Fecal excretions were collected from rainbow trout (Salmo gairdneri) in metabolism chambers. In this method of collection the daily excretion is suspended in about 1 L of water. Aliquots of the suspension were separated into solid and liquid fractions by settling, centrifuging, or filtering. Solid and liquid fractions and the...
Continuous monitoring of Mount St. Helens Volcano

1980, Earthquake Information Bulletin (USGS) (12) 220-227
Day by day monitoring of the Mount St. Helens Volcano. These are four scenarios, very different scenarios, that can occur in a average week at Mount St. Helens. Ranging from eruptions of gas and to steam to eruptions of ash and pyroclastic flows to even calm days. This example of...

Chandler S. Robbins
1980, North American Bird Bander (5) 34-34
Despite a 22% increase in net-hours, the number of new birds banded dropped 26% from 1977. The decrease was noted in each month and was spread among all of the commonest species, including summer residents, winter residents, permanent residents, and transients. The greatest declines were in Scarlet Tanager (84%), Blue...
Visitor use patterns in Yosemite National Park
J. W. van Wagtendonk
1980, Journal of Travel Research (19) 12-17
After several years of dramatic increases, visitor use in Yosemite National Park has leveled off to an average of 2.4 million visits per year. Coincident with this decline in the growth rate, there have been some changes in visitation trends and patterns. Data collected in the park show that the...

D.A. Clague, E.D. Jackson, T. L. Wright
1980, Bulletin Volcanologique (43) 641-656
Hualalai is one of five volcanoes whose eruptions built the island of Hawaii. The historic 1800-1801 flows and the analyzed prehistoric flows exposed at the surface are alkalic basalts except for a trachyte cone and flow at Puu Waawaa and a trachyte maar deposit near Waha Pele. The 1800-1801 eruption...
