Synmagmatic deformation in the underplated igneous complex of the Ivrea-Verbano zone
J. E. Quick, S. Sinigoi, L. Negrini, G. Demarchi, A. Mayer
1992, Geology (20) 613-616
The Ivrea-Verbano zone, northern Italy, contains an igneous complex up to 10 km thick that is thought to have been intruded near the interface between the continental crust and mantle during the late Paleozoic. New data indicate that this complex is pervasively deformed...
Anomalous abundances of deep-sea fauna on a rocky bottom exposed to strong currents
A. Genin, C. K. Paull, William P. Dillon
1992, Deep Sea Research Part A, Oceanographic Research Papers (39) 293-302
Unusually high abundances of sponges and gorgonian corals, covering as much as 25% of the bottom, occur at depths greater than 3.5 km on the Blake Spur, a rocky cliff-dominated feature on the western Atlantic continental margin. This is the first report of such high abundances of megafauna from a...
Uranium-series isochron dating at El Castillo Cave (Cantabria, Spain): The "Acheulean"/"Mousterian" question
J. L. Bischoff, Jose Francisco Garcia, L.G. Straus
1992, Journal of Archaeological Science (19) 49-62
A massive flowstone layer, Level 23, near the base of the stratigraphic sequence in El Castillo Cave (Cantabria, Spain), is dated by the uranium-series isochron method to 89+11/−10 ka bp. The flowstone separates cultural layers traditionally labelled “Mousterian” (above) and “Acheulean” (below). The date reported here, in association with other...
Lead isotopes in iron and manganese oxide coatings and their use as an exploration guide for concealed mineralization
B.L. Gulson, S. E. Church, K.J. Mizon, A. L. Meier
1992, Applied Geochemistry (7) 495-511
Lead isotopes from Fe and Mn oxides that coat stream pebbles from around the Mount Emmons porphyry molybdenum deposit in Colorado were studied to assess the feasibility of using Pb isotopes to detect concealed mineral deposits. The Fe/Mn oxide coatings were analyzed to determine their elemental concentrations using ICP-AES. The...
Case report: Epithelial intracytoplasmic herpes viral inclusions associated with an outbreak of duck virus enteritis
B.C. Barr, David A. Jessup, Douglas E. Docherty, L.J. Lownestine
1992, Avian Diseases (36) 164-168
Several muscovy ducks from a free-roaming flock of 65 muscovy and mallard ducks died over a 3-week period. Three muscovy ducks were necropsied. Gross and microscopic changes were compatible with duck virus enteritis, and the virus was isolated. In addition to intranuclear viral inclusion bodies in several tissues, intracytoplasmic inclusion...
Geochemical exploration for copper-nickel deposits in the cool-humid climate of northeastern Minnesota
W. R. Miller, W. H. Ficklin, J. B. McHugh
1992, Journal of Geochemical Exploration (42) 327-344
Water was used as a medium for geochemical exploration to detect copper-nickel mineralization along the basal zone of the Duluth Complex. Ni2+ is the most important pathfinder for the detection of the mineralized rocks, followed by Cu2+ and SO42− and to a lesser extent...
Use of geochemical biomarkers in bottom sediment to track oil from a spill, San Francisco Bay, California
F. D. Hostettler, J. B. Rapp, K.A. Kvenvolden
1992, Marine Pollution Bulletin (24) 15-20
In April 1988, approximately 1500 m3 of a San Joaquin Valley crude oil were accidentally released from a Shell Oil Co. refinery near Martinez, Californa. The oil flowed into Carquinez Strait and Suisun Bay in northern San Francisco Bay Sediment and oil samples were collected within a week and analysed...
Earthquakes March-April 1992
Waverly J. Person
1992, Earthquakes & Volcanoes (USGS) (23) 227-234
The months of March and April were quite active seismically speaking. There was one major earthquake (7.0<M<8.0), a magnitude 7.1 shock on April 25 in northern California. Earthquake-related deaths were reported in Iran, Costa Rica, Turkey, and Germany....

Intraspecific mitochondrial DNA variation in North American cervids
M. A. Cronin
1992, Journal of Mammalogy (73) 70-82
Intraspecific variation in mitochondrial DNA of North American cervids was assessed with restriction enzymes to determine relationships among populations and subspecies. No variation was detected in moose (Alces alces) and little in elk (Cervus elaphus). Caribou (Rangifer tarandus), white-tailed deer (Odocoileus virginianus), and mule deer (Odocoileus hemionus) possessed considerable...
Foraging on prey that are modified by parasites
Kevin D. Lafferty
1992, American Naturalist (140) 854-867
A model that weighs the energetic cost of parasitism for a predator against the energetic value of prey items that transmit the parasite to the predator suggests that there is often no selective pressure to avoid parasitized prey This offers an explanation for why parasites so frequently exploit predators and...
Biological diversity of a temporary pond herpetofauna in north Florida sandhills
C.K. Dodd Jr.
1992, Biodiversity and Conservation (1) 125-142
From 1985 through 1990, the herpetofauna of a temporary pond in an uplands longleaf pine sandhills community in north-central Florida was monitored. A drift fence completely encircled the pond. Animals were captured in pitfall traps and marked as they entered and exited the pond basin. I captured 16 155 individuals...

B. E. Law
1992, Geological Society of America Bulletin (104) 192-207
Horizontal and vertical thermal maturity patterns and time-temperature modeling of Cretaceous and Tertiary rocks in the San Juan Basin of southwestern Colorado and northwestern New Mexico indicate that the high levels of thermal maturity in the northern part of the basin are due...
A relation among geology, tectonics, and velocity structure, western to central Nevada Basin and Range
R. D. Catchings
1992, Geological Society of America Bulletin (104) 1178-1192
In the northwestern to central Nevada Basin and Range, there are correlations between velocity and specific geologic structures of the crust. Mapped range-bounding faults at the surface can be traced to appreciable (10 km) depths based on velocity variations and are consistent with...
Evaluation of methyl fluoride and dimethyl ether as inhibitors of aerobic methane oxidation
Ronald S. Oremland, Charles W. Culbertson
1992, Applied and Environmental Microbiology (58) 2983-2992
Methyl fluoride (MF) and dimethyl ether (DME) were effective inhibitors of aerobic methanotrophy in a variety of soils. MF and DME blocked consumption of CH4 as well as the oxidation of 14CH4 to 14CO2, but neither MF nor DME affected the oxidation of [14C]methanol or [14C]formate to 14CO2. Cooxidation of ethane and propane by methane-oxidizing...

A hydrogen-oxidizing, Fe(III)-reducing microorganism from the Great Bay estuary, New Hampshire
F. Caccavo Jr., R.P. Blakemore, Derek R. Lovley
1992, Applied and Environmental Microbiology (58) 3211-3216
A dissimilatory Fe(III)- and Mn(IV)-reducing bacterium was isolated from bottom sediments of the Great Bay estuary, New Hampshire. The isolate was a facultatively anaerobic gram-negative rod which did not appear to fit into any previously described genus. It was temporarily designated strain BrY. BrY grew anaerobically in a defined medium...

A revised configuration of the southern California uplift
R. O. Castle, T.D. Gilmore
1992, Geological Society of America Bulletin (104) 1577-1591
Recently recovered archival leveling data from southwestern Arizona and adjacent parts of California compel major revisions in the configuration and interpretation of the southern California uplift, both at its culmination and following its partial collapse. Re-examination of the older vertical-control record indicates that...
