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...
Low-frequency radiation from point sources in a fluid-filled borehole
Myung W. Lee
1986, Geophysics (51) 1801-1807
Far-field displacement fields have been derived for an impulsive point force acting on a fluid-filled borehole wall under the assumption that the borehole diameter is small compared to the wavelength involved. The displacements due to an arbitrary source can be computed easily by combining the solutions for the impulsive sources.In...
Marine birds

1986, Book chapter, The Gulf of Alaska: Physical environment and biological resources
In this chapter we review existing knowledge of marine birds in the Gulf of Alaska. Three estuarine systems in the Gulf provide critical habitat for migratory shorebirds and waterfowl: 1) the Stikine River Delta, 2) Cook Inlet, and 3) the Copper River Delta. Over 20 million waterbirds are estimated to...

Chemical variability in the Sacramento River and in Northern San Francisco Bay
L. E. Schemel, S.W. Hager
1986, Estuaries (9) 270-283
Specific conductance and concentrations of alkalinity, dissolved silica, nitrate, and ammonium were measured daily in the Sacramento River flow to northern San Francisco Bay during the rainfall seasons of 1983 and 1984 (high flow) and during late summer and early fall of 1984 (low flow). Flow and concentrations of chemical...
Volcanoes and atmospheres; catastrophic influences on the planets
S. W. Kieffer
1986, Earthquakes & Volcanoes (USGS) (18) 76-83
For a rare and brief instant in geologic time, we can imagine that the sulfurous, chromatic surface of Io (one of the satellites of Jupiter) lies quiet. Perhaps stars glisten brilliantly through the tenuous nigh sky. Here and there, thick icy fogs enshroud fumaroles where sulfur dioxide leaks from the...
Louisiana hydrologic atlas map no. 1: Mean annual runoff in Louisiana
Harry C. McWreath III, Alfred S. Lowe
1986, Water-Resources Investigations Report 86-4149
The map shows the mean annual runoff from drainage basins in Louisiana exclusive of those in the coastal zone and the alluvial valleys of the Mississippi, Ouachita, and Red Rivers. The mean annual runoff for the State of Louisiana varies from 0.7 (cu ft/s)/sq mi in the Sabine and Red...

Platinum-group element geochemistry of zoned ultramafic intrusive suites, Klamath Mountains, California and Oregon
F. Gray, N.J. Page, C.A. Carlson, S. A. Wilson, R. R. Carlson
1986, Economic Geology (81) 1252-1260
Three postorogenic Alaskan-type ultramafic to mafic intrusive suites in the Klamath Mountains, ranging in age from 142 to 163 m.y. and intruding metavolcanic, metasedimentary, or ophiolitic cumulate ultramafie to gabbroic rocks, were examined for their platinum-group element content. The Lower Coon Mountain pluton consists of layered clinopyroxene-rich lithologies occurring in...

Chemistry of illite/smectite and end-member illite
J. Srodon, D.J. Morgan, E.V. Eslinger, D. D. Eberl, M.R. Karlinger
1986, Clays and Clay Minerals (34) 368-378
Chemical data from three different series of diagenetic illite/smectites (I/S), analyzed statistically by two regresion techniques, indicate that the content of fixed-K per illite layer is not constant, but ranges from ∼0.55 per O10(OH)2 for illite layers in randomly interstratified I/S (R=0; > 50% smectite layers) to ∼1.0 per O10(OH)2 for illite...
Geochemical exploration for mineralized breccia pipes in northern Arizona, U.S.A.
K. J. Wenrich
1986, Applied Geochemistry (1) 469-485
Thousands of solution-collapse breccia pipe crop out in the canyons and on the plateaus of northern Arizona. Over 80 of these are known to contain U or Cu mineralized rock. The high-grade U ore associated with potentially economic concentrations of Ag, Pb, Zn, Cu, Co and Ni in some of...

Louisiana hydrologic atlas map no. 2: Areal extent of freshwater in major aquifers of Louisiana
Charles W. Smoot
1986, Water-Resources Investigations Report 86-4150
The areal availability of freshwater (cl content < 250 mg/L) in 14 major aquifers in Louisiana was investigated. The depth of occurrence of fresh groundwater in Louisiana is variable. The aquifers were mapped to show their areal extent from the outcrop or subcrop to the downdip limit of freshwater. Water...
A field guide to valuable underwater aquatic plants of the Great Lakes
Donald W. Schloesser
1986, Report
Underwater plants are a valuable part of the Great Lakes ecosystem, providing food and shelter for aquatic animals. Aquatic plants also help stabilize sediments, thereby reducing shoreline erosion. Annual fall die-offs of underwater plants provide food and shelter for overwintering small aquatic animals such as insects, snails, and freshwater shrimp. In...

Magmatic inclusions in silicic and intermediate volcanic rocks
Charles R. Bacon
1986, Journal of Geophysical Research B: Solid Earth (91) 6091-6112
Fine‐grained ellipsoidal inclusions from a few millimeters to over l m in size are present in many intermediate to silicic lava flows and domes. Only recently has it become widely accepted that such inclusions are chilled blobs of magma. Their magmatic origin is manifested by vesicularity and high groundmass porosity,...

Percentage entrainment of constituent loads in urban runoff, south Florida
R. A. Miller
1985, Water-Resources Investigations Report 84-4329
Runoff quantity and quality data from four urban basins in south Florida were analyzed to determine the entrainment of total nitrogen, total phosphorus, total carbon, chemical oxygen demand, suspended solids, and total lead within the stormwater runoff. Land use of the homogeneously developed basins are residential (single family), highway, commercial,...
