Origin of two clay-mineral facies of the Potomac Group (Cretaceous) in the Middle Atlantic States
Lucy M. Force, George K. Moncure
1978, Journal of Research of the U.S. Geological Survey (6) 203-214
Sedimentary clay that crops out in the coastal plains of New Jersey, Delaware, the part of Maryland north and east of Washington, B.C., and the northeast half of Washington, D.C., in the nonmarine Cretaceous Potomac Group is predominantly kaolinite and illite. In contrast, in part of southeastern Maryland, the...
A tuya in Togiak Valley, Southwest Alaska
J. M. Hoare, W. L. Coonrad
1978, Journal of Research of the U.S. Geological Survey (6) 193-201
The shape, composition, structure, and location of a conspicuous flat-topped mountain in the lower Togiak Valley, southwest Alaska, all indicate that it formed by a subglacial volcanic eruption of olivine basalt. Volcanoes of this type are known as "tuyas." The Togiak tuya erupted into an intraglacial lake in a hole...
Remote-sensing methods for monitoring surface coal mining in the northern Great Plains
Ned Mamula Jr.
1978, Journal of Research of the U.S. Geological Survey (6) 149-160
Recent studies at a large surface coal mine in southern Montana confirm that remote sensing is both feasible and effective for gathering land-use and environmental data (spatial, dynamic, and seasonal) for large-scale surface mines in the northern Great Plains. The Western Energy Co.'s Rosebud mine near Colstrip, Mont., was selected...
Impact of sewerage systems on stream base flow and ground-water recharge on Long Island, New York
E.J. Pluhowski, A. G. Spinello
1978, Journal of Research of the U.S. Geological Survey (6) 263-271
Statistically significant decreases in the ratio of base flow to total flow of streams along the south shore of Long Island, N.Y., are due to the use of expanding storm-sewer and sanitary-sewer networks. Base-flow losses due to sewering ranging from virtually none at Connetquot River (largely unaffected by urban development)...
Spectrochemical determination of submicrogram amounts of tungsten in geologic materials
Reinhard W. Leinz, David J. Grimes
1978, Journal of Research of the U.S. Geological Survey (6) 259-262
A rapid, sensitive, emission spectrographic method for the determination of tungsten in geologic materials has been developed. Sample fusion with potassium hydroxide followed by a hot-water leach renders the tungsten soluble. Acidification of the solution, reduction with titanium trichloride, complexing with thiocyanate, and ether extraction separate and concentrate the tungsten....
Thermogenic gases in near-surface sediments of Norton Sound, Alaska
C. Hans Nelson, Keith A. Kvenvolden, Edward C. Clukey
1978, Conference Paper
A plume of hydrocarbon gases, assumed to be of thermogenic origin based on chemical compositions, has been noted by others in the water column of Norton Sound about 40 km south of Nome, Alaska. We used detailed geophysical transects, side-scan sonar, underwater television, and chromatographic analyses of gases in near-surface...

Remote-sensing and subsurface definition of facies and structure related to uranium deposits, Powder River Basin, Wyoming
G. L. Raines, Terry W. Offield, E.S. Santos
1978, Economic Geology (73) 1706-1723
Computer-enhanced Landsat images of the southern Powder River Basin have been used to define facies and linear structural features within the Wasatch Formation. The facies distribution is detectable primarily because of a relation of vegetation density and type to the local substrate. The surface indications of facies are confirmed by...
The Aleutian Basin, Bering Sea a frontier area for hydrocarbon exploration
Alan K. Cooper, David W. Scholl, A.F. Marlow, Jonathan R. Childs, George D. Redden, Keith A. Kvenvolden
1978, Conference Paper, Tenth annual Offshore Technology Conference proceedings
The Aleutian Basin is the deep water (>3000 m) basin that lies north of the Aleutian Islands adjacent to the Bering Sea continental shelf. The basin, about the size of the state of Texas, is underlain by a 2-9 km-thick flat-lying sequence of mostly Cenozoic sediment and rock that includes...
Quality of the water in Borrow Ponds near a major highway interchange, Dade County, Florida, October-November 1977
T.R. Beaven, Benjamin F. McPherson
1978, Open-File Report 78-1029
Water, bottom sediment, and aquatic plants were sampled from ponds near a major south Florida highway interchange to document concentrations of selected constituents in an aquatic environment near heavy vehicular traffic. Generally, concentrations of constituents were within the range expected in an uncontaminated environment in south Florida. However, concentrations did...
Urban stormwater runoff data for a residential area, Pompano Beach, Florida
Harold C. Mattraw Jr., Jack Hardee, Robert A. Miller
1978, Open-File Report 78-324
Rainfall, storm-sewer discharge, and water-quality analyses of storm runoff are summarized for a single-family residential area near Pompano Beach, Florida. The area of the drainage basin is 41 acres of which 61 percent is pervious sod lawns and 39 percent is impervious roofs, driveways and streets. The land surface is...
Effects of bottom sediments on infiltration from the Miami and tributary canals to the Biscayne aquifer Dade County, Florida
Wesley L. Miller
1978, Water-Resources Investigations Report 78-36
Infiltration from the Miami Canal and its tributaries is an important source of recharge to the Biscayne aquifer in the vicinity of the Miami Springs-Hialeah well fields. Estimates of pumpage contributed by canal infiltration decreased from nearly 100 percent in the late 1940 's to 50 percent in May 1973...
Biscayne aquifer, southeast Florida
Howard Klein, John E. Hull
1978, Water-Resources Investigations Report 78-107
Peak daily pumpage from the highly permeable, unconfined Biscayne aquifer for public water-supply systems in southeast Florida in 1975 was about 500 million gallons. Another 165 million gallons was withdrawn daily for irrigation. Recharge to the aquifer is primarily by local rainfall. Discharge is by evapotranspiration, canal drainage, coastal seepage,...
Jordan aquifer of Iowa
P. J. Horick, W. L. Steinhilber
1978, Report
Water demand for all uses in Iowa is increasing at an accelerated rate. Demand has increased from about 1,800 million gallons per day in 1955 to 3,500 million gallons per day in 1975 (MacKichan, 1957; Murray and Reeves, 1977). By the year 2020, water demand is expected to be eight...

Metamorphic forsterite and diopside from the ultramafic complex at the Tuolumne River, California
B. A. Morgan
1978, Journal of Research of the U.S. Geological Survey (6) 73-80
Metamorphic forsterite (Fo=98) and diopside (Wo:En:Fs=48.5:49.5:2.0) have been, formed from serpentinite within intensely sheared zones in the large ultramafic complex at the Tuolumne River near Sonora, Calif. Bladelike grains of forsterite are elongate, parallel to c, and have prominent idiomorphic faces developed in (010). Metamorphic diopside occurs as small grains,...
Determination of runoff coefficients of storm-water-basin drainage areas on Long Island, New York, by using maximum-stage gages
D. A. Aronson
1978, Journal of Research of the U.S. Geological Survey (6) 11-21
A method for determining runoff coefficients indirectly without direct measurement of volume of runoff was developed for drainage areas of selected storm-water basins on Long Island, N.Y., to expedite evaluation of basin performance. The method requires a maximum-stage gage to record the maximum water level attained in the basin...
