Franciscan complex calera limestones: Accreted remnants of farallon plate oceanic plateaus
J.A. Tarduno, M. McWilliams, M.G. Debiche, W.V. Sliter, M.C. Blake
1985, Nature (317) 345-347
The Calera Limestone, part of the Franciscan Complex of northern California, may have formed in a palaeoenvironment similar to Hess and Shatsky Rises of the present north-west Pacific1. We report here new palaeomagnetic results, palaeontological data and recent plate-motion models that reinforce this assertion. The Calera Limestone may have formed...
Morphology of the Ebro fan valleys from SeaMARC and sea beam profiles
B. Alonso, K.A. Kastens, A. Maldonado, A. Malinverno, C.H. Nelson, S. O'Connell, A. Palanques, William B. F. Ryan
1985, Geo-Marine Letters (5) 141-148
The northern continental slope off the Ebro Delta has a badland topography indicating major slope erosion and mass movement of material that deposits sediment into a ponded lobe. The southern slope has a low degree of mass movement activity and slope valleys feed channel levee-complexes on a steep continental rise....
Germanium geochemistry and mineralogy
L.R. Bernstein
1985, Geochimica et Cosmochimica Acta (49) 2409-2422
Germanium is enriched in the following geologic environments:1.(1) iron meteorites and terrestrial iron-nickel;2.(2) sulfide ore deposits, particularly those hosted by sedimentary rocks;3.(3) iron oxide deposits;4.(4) oxidized zones of Ge-bearing sulfide deposits;5.(5) pegmatites, greisens, and skarns; and6.(6) coal...
High-frequency observations and source parameters of microearthquakes recorded at hard-rock sites
Edward Cranswick, Robert Wetmiller, John Boatwright
1985, Bulletin of the Seismological Society of America (75) 1535-1567
We have estimated the source parameters of 53 microearthquakes recorded in July 1983 which were aftershocks of the Miramichi, New Brunswick, earthquake that occurred on 9 January 1982. These events were recorded by local three-component digital seismographs at 400 sps/component from 2-Hz velocity transducers sited directly on glacially scoured crystalline...
Transport and deposition of river sediment in the Changjiang estuary and adjacent continental shelf
John D. Milliman, S. Huang-ting, Y. Zuo-sheng, R.H. Mead
1985, Continental Shelf Research (4) 37-45
Hydrographic observations, suspended-sediment measurements, and historical data indicate transport paths and sinks for sediment within the Changjiang estuary and adjacent shelf. Most of the sediment transported by the Changjiang to the ocean is carried through the North Channel of the South Branch. Sediment transport is directly related to river stage,...
Geochemical investigations of polychlorinated dibenzo-p-dioxins in the subsurface environment at an abandoned wood-treatment facility
W. E. Pereira, C.E. Rostad, M.E. Sisak
1985, Environmental Toxicology and Chemistry (4) 629-639
The discharge of effluents containing creosote and pentachlorophenol into two unlined surface impoundments at a wood-treatment facility in Pensacola, Florida, resulted in contamination of the underlying sand and gravel aquifer. These wastes contained significant amounts of chlorinated dioxins, such as isomers of hexa- and heptachlorodibenzo-p-dioxins and octachlorodibenzo-p-dioxin, probably derived from...
Water balance models in one-month-ahead streamflow forecasting
William M. Alley
1985, Water Resources Research (21) 597-606
Techniques are tested that incorporate information from water balance models in making 1-month-ahead streamflow forecasts in New Jersey. The results are compared to those based on simple autoregressive time series models. The relative performance of the models is dependent on the month of the year in question. The water balance...
Immunizing Canada geese against avian cholera
J.I. Price
1985, Wildlife Society Bulletin (13) 508-515
A small flock of captive giant Canada geese were vaccinated with the experimental bac- terin in Nebraska to test its efficacy under field conditions. Only 2 of 157 vaccinates died from avian cholera during an annual spring die-off....
