Changes in complex resistivity during creep in granite
D.A. Lockner, J.D. Byerlee
1986, Pure and Applied Geophysics PAGEOPH (124) 659-676
A sample of Westerly granite was deformed under constant stress conditions: a pore pressure of 5 MPa, a confining pressure of 10 MPa, and an axial load of 170 MPa. Pore volume changes were determined by measuring the volume of pore fluid (0.01 M KClaq) injected into the sample. After...

**1**5N-NMR INVESTIGATION OF HYDROXYLAMINE DERIVATIZED HUMIC SUBSTANCES.
Kevin A. Thorn, Jeffrey B. Arterburn, Michael A. Mikita
1986, Conference Paper, National Meeting - American Chemical Society, Division of Environmental Chemistry
Humic substances are the most abundant naturally occurring refactory organic compounds in soils and water. They have a broad range of physical, chemical and physiological properties. In soils, humic substances contribute to the cation exchange capacity, help maintain the physical structure, and play a role in plant growth and nutrition....
Evidence for a stronger oxygen-minimum zone off central California during late Pleistocene to early Holocene
J.V. Gardner, E. Hemphill-Haley
1986, Geology (14) 691-694
Of 31 deep-sea cores collected along the central California continental slope, 18 have distinctly laminated sediment at depth, but none have laminations in the top few centimetres. The cores with laminated facies are restricted to water depths between 508 and 1508 m, but...
Precambrian basement geology of North and South Dakota
J. S. Klasner, E. R. King
1986, Canadian Journal of Earth Sciences (23) 1083-1102
Combined analysis of drill-hole, gravity, and magnetic data indicates that the buried Precambrian basement rocks of the Dakotas can be divided into several lithotectonic terranes. Eastern North Dakota and northeastern South Dakota are underlain by Archean gneiss. Except for the Black Hills region of South Dakota, where Archean rocks are...
Effects of rearing density on growth and survival of lake trout
R. W. Soderberg, W. F. Krise
1986, Progressive Fish-Culturist (48) 30-32
Lake trout (Salvelinus namaycush) were reared at density indices (allowable density in pounds/cubic foot divided by fish length in inches) of 0.25, 0.50, 1.0, and 2.0 in cages suspended in circular tanks. Water flow rates were such that dissolved oxygen remained above 8 ppm within all the cages. Thus treatment...
NEW STUDIES OF URBAN FLOOD FREQUENCY IN THE SOUTHEASTERN UNITED STATES.
Vernon B. Sauer
1986, Transportation Research Record 10-15
Five reports dealing with flood magnitude and frequency in urban areas in the southeastern United States have been published during the past 2 years by the U. S. Geological Survey (USGS). These reports are based on data collected in Tampa and Tallahassee, Florida; Atlanta, Georgia; and several cities in Alabama...

Physical and chemical characteristics of water in coal-mine ponds of eastern Oklahoma.
S. P. Blumer, L. J. Slack
1986, Oklahoma Geology Notes (46) 128-134
Coal-mine ponds cover 4000 acres and have a storage capacity of about 100 000 acre-feet. They are important wild-life habitats and contribute locally to agricultural and municipal water supply. The physical and chemical properties of the water are very variable. By and large, the pond waters showed a lack of...
Mycoplasma contamination in fish cell lines: An evaluation of detection by differential incorporation of 3H-uridine and 14C-uracil
C. L. Schultz, B. C. Lidgerding, P. E. McAllister, F. M. Hetrick
1986, Journal of Fish Diseases (9) 117-122
Differential incorporation of uridine and uracil was used to assay for mycoplasma contamination in five fish cell lines: bluegill fry (BF-2), chinook salmon embryo (CHSE-214), epithelioma papillosum cyprini (EPC), fathead minnow (FHM) and rainbow trout gonad (RTG-2). The method was not suitable for monitoring BF-2, CHSE-214, FHM, and RTG-2 cell...

Catastrophic flooding and eruption of ash-flow tuff at Medicine Lake volcano, California
J.M. Donnelly-Nolan, K.M. Nolan
1986, Geology (14) 875-878
Catastrophic flooding has eroded a discontinuous network of oversized anastomosing channels on the northwest flank of the Medicine Lake volcano. Most of these previously unrecognized channels were cut into an andesitic ash-flow tuff; boulders as large as 2 m in intermediate diameter were...
Design and application of vacuum degassers
J. T. Fuss
1986, Progressive Fish-Culturist (48) 215-221
Designs of vacuum degassers, which alleviate gas supersaturation in hatchery waters, have progressed greatly in recent years. Basic rules of thumb now exist by which the feasibility of vacuum degassers can be determined for particular facilities, and by which complete systems can be designed and built to meet local needs....
Role of replacement in the genesis of anorthosite in the Boehls Butte area, Idaho
Anna Hietanen
1986, Geological Society of Finland, Bulletin (58) 71-79
In the Boehls Butte area, Idaho, three large and numerous small lenses of layered to massive anorthosite consisting of two, and locally three, types of plagioclase and minor hornblende and micas occur in aluminum silicate-rich garnet mica schist. In most of this anorthosite, andesine megacrysts with bytownite inclusions are embedded...

Bernard J. Franks
H.C. Mattraw Jr., editor(s)
1986, Water Supply Paper 2285
Ground- and surface-water contamination by pesticides used in the wood-preserving industry is widespread in the United States. Pine poles were treated with wood preservatives from 1902 to 1981 at a creosote works near Pensacola, Florida. Diesel fuel, creosote, and pentachlorophenol were discharged to two unlined impoundments that had a direct...
Magnesioferrite from the Cretaceous-Tertiary boundary, Caravaca, Spain
B.F. Bohor, E.E. Foord, R. Ganapathy
1986, Earth and Planetary Science Letters (81) 57-66
Magnesioferrite grading toward magnetite has been identified as a very small but meaningful constituent of the basal iron-rich portion of the Cretaceous-Tertiary (K-T) boundary clay at the Barranco del Gredero section, Caravaca, Spain. This spinel-type phase and others of the spinel group, found in K-T boundary clays at many widely...
Improved phase-ellipse method for in-situ geophone calibration
Huaibao P. Liu, L. Peselnick
1986, Geophysical Prospecting (34) 537-544
For amplitude and phase response calibration of moving-coil electromagnetic geophones two parameters are needed, namely, the geophone natural frequency, f0, and the geophone upper resonance frequency fu. The phase-ellipse method is commonly used for the in situ determination of these parameters. For a given signal-to-noise ratio, the precision of the measurement off0 andfu depends...
A new view for resource managers
Robert H. Haas
1986, Rangelands (8) 99-102
In decades past, the rancher depended upon reports from cowboys to gather information he needed to make management decisions. Today, the vast open ranges of the cowboy era are mostly gone in the United States-fenced into pastures, paddocks, or fields that are now discrete management units. But fencing in the...
