The least exacting demand that can be made of any model is that it serves as a device whereby we can predict actual physical happenings. Another demand which could be made is that the physical happenings predicted be in some way relevant to man, either by allowing him to anticipate...

Calculated geochronology and stress field orientations along the Hawaiian chain
E.D. Jackson, H. R. Shaw, K.E. Bargar
1975, Earth and Planetary Science Letters (26) 145-155
A new method has been discovered for calculating ages of the main shield building stages of volcanoes along the Hawaiian chain from Kilauea to the Hawaiian-Emperor bend. The method is based on a graphical technique for hypothetical subtraction of distance intervals that...
Short chain aliphatic acid anions in oil field waters and their contribution to the measured alkalinity
L.M. Willey, Y.K. Kharaka, T. S. Presser, J. B. Rapp, I. Barnes
1975, Geochimica et Cosmochimica Acta (39) 1707-1711
High alkalinity values found in some formation waters from Kettleman North Dome oil field are due chiefly to acetate and propionate ions, with some contribution from higher molecular weight organic acid ions. Some of these waters contain no detectable bicarbonate alkalinity. For waters...
Thin-section electron microscopy of mature Myxosoma cerebralis (Myxosporidea) spores
P.D. Lunger, B.L. Rhoads, K. Wolf, M.E. Markiw
1975, Journal of Parasitology (61) 476-480
The morphology of purified, mature Myxosoma cerebralis spores was examined by thin-section electron microscopy. Surface architecture corresponded closely to that described in an earlier scanning electron microscopy study of this organism (Lom and Hoffman, 1971). A uniformly thick spore wall is composed of finely granular, electron-lucent material. Intrawall "valvoplasm" at...
Location of the non-tidal current null zone in northern San Francisco Bay
David H. Peterson, T. J. Conomos, W. W. Broenkow, Patrick C. Doherty
1975, Estuarine and Coastal Marine Science (3) 1-11
Variations in Sacramento-San Joaquin River discharge into northern San Francisco Bay causes shifts in location of the bottom density current null zone. At a river flow of 2000 m3/s this null zone is approximately 20 km from the seaward end of the estuary,...
Trace element evaluation of a suite of rocks from Reunion Island, Indian Ocean
R. A. Zielinski
1975, Geochimica et Cosmochimica Acta (39) 713-734
Reunion Island consists of an olivine-basalt shield capped by a series of flows and intrusives ranging from hawaiite through trachyte. Eleven rocks representing the total compositional sequence have been analyzed for U, Th and REE. Eight of the rocks (group 1) have positive-slope, parallel, chondrite-normalized REE fractionation patterns. Using a...
Death feigning by ducks in response to predation by red foxes (Vulpes fulva)
Alan B. Sargeant, L. E. Eberhardt
1975, American Midland Naturalist (94) 108-119
Predation by captive red foxes (Vulpes fulva) on approximately 50 ducks comprised of five species was observed in tests conducted at the Northern Prairie Wildlife Research Center, Jamestown, North Dakota. Most ducks were attacked from a rear or lateral position and seized in the cervical or thoracic region. All birds...

1975, Earthquake Information Bulletin (USGS) (7) 8-13
The Rio Grande Rift, one of the major geologic structures of the Southwest, cuts through the center of New Mexico from north to south. The rift is also referred to as the Rio Grande Trench and as the Rio Grande Trough. It extends from the northern end of the San...
Water development for irrigation in northwestern Kansas
Edward D. Jenkins, Marilyn E. Pabst
1975, Report
Northwestern Kansas, an area of 8,050 square miles (21,000 square kilometres), is a flat to gently rolling plain that is dissected by the Smoky Hill and Republican Rivers. Loessial soils underlying the plain are ideal for cultivation.The climate is semiarid with the mean annual precipitation ranging from 16 to 21...
Streamflow characteristics in northeastern Utah and adjacent areas
Fred K. Fields
1975, Utah Basic-Data Release 25
This report contains statistical summaries of streamflow records from 74 gaging stations, which are mostly in northeastern Utah. Low- flow, high-flow, and flow-duration summaries were compiled from daily discharge values; and flows of each month are compared through correlation with flows of 1, 2, and 12 months in the future....
Hydrologic data of the coastal drainage basins of southeastern Massachusetts, Weir River, Hingham, to Jonas River, Kingston
John R. Williams, Richard E. Willey, Gary D. Tasker
1975, Massachusetts Hydrologic - Data Report 16
The principal basins are those of Weir River, James Brook, Bound Brook, North River, South River, and Jones River, all draining to Massachusetts Bay and Cape Cod Bay. These basins are bounded on the north by the Weymouth River basins, on the west by the Taunton River basin, and on...
Uranium determination in natural water by the fissiontrack technique
G.M. Reimer
1975, Journal of Geochemical Exploration (4) 425-431
The fission track technique, utilizing the neutron-induced fission of uranium-235, provides a versatile analytical method for the routine analysis of uranium in liquid samples of natural water. A detector is immersed in the sample and both are irradiated. The fission track density observed...
Sandrewia, n. gen., a problematical plant from the Lower Permian of Texas and Kansas
S.H. Mamay
1975, Review of Palaeobotany and Palynology (20) 75-83
Sandrewia, n. gen., monotypified by S. texana, n. sp., is a plant from Lower Permian beds of north-central Texas and east-central Kansas. It is characterized by stout axes with spirally disposed, laxly inserted, petiolate leaves; the laminae are broadly flabelliform with coarse, open venation....

Geothermal significance of eastward increase in age of upper Cenozoic rhyolitic domes in southeastern Oregon
Norman S. MacLeod, George Walton Walker, Edwin H. McKee
1975, Open-File Report 75-348
Rhyolitic domes, flows, and ash-flow tuffs of Miocene to Holocene age form an important part of the thick sequence of Cenozoic volcanic rocks that cover southeastern Oregon east of the Cascade Range. Rhyolitic domes 11-17 m.y. old are widespread, particularly in the easternmost part of the state and in adjacent...
Gut morphology of mallards in relation to diet quality
M. R. Miller
1975, Journal of Wildlife Management (39) 168-173
Digestive organ lengths, weights, and volumes in each of three groups of mallards (Anas platyrhynchos) were determined at the end of a 21-day period, during which one group was starter (control diet), another group was fed whole corn (low fiber content), and the third fed alfalfa pellets (high fiber content)...

Robert McLaughlin
1974, Journal of Research of the U.S. Geological Survey (2) 593-598
The Sargent-Berrocal fault zone is a belt of thrust faults extending for about 58 mi (94 km) southeastward from the vicinity of Los Altos to San Juan Bautista, Calif. The fault zone generally dips southwestward toward the adjacent San Andreas fault at low to steep angles, and the southwest...

G.C. Curtin, H. D. King
1974, Journal of Research of the U.S. Geological Survey (2) 581-592
Geochemical studies in the Chief Mountain Soda Creek area, Clear Creek County, Colo., show that anomalously high amounts of Au, Ag, Pb, Zn, Cd, and Bi in mull ash, and Cu and Hg in soil, correspond to a negative gravity anomaly in the Front Range mineral belt. The correspondence of...

A quartzite unit occurring between the rocks of the Precambrian Apache Group and those of the Cambrian Abrigo Formation in the Vekol Mountains, Final County, Ariz., has been called both Troy Quartzite (Precambrian) and Bolsa(?) Quartzite (Cambrian). Regional and local geologic relationships indicate that this intervening unit is definitely the...

Polychlorinated biphenyl toxicity to Japanese quail as related to degree of chlorination
E. F. Hill, R.G. Heath, J. W. Spann, J.D. Williams
1974, Poultry Science (53) 597-604
To learn if the percentage of chlorine in a mixture of polychlorinated biphenyls (PCB’s) alone determines toxicity, Japanese quail were fed diets containing Aroclor 1248, 1254, or 1260 at levels that added equal amounts of chlorine to the feed. The experiment comprised two consecutive 5-day periods; three sublethal concentrations of...
