Water quality characteristics of six small lakes in Missouri: Mo. Dept. of Natural Resources.
James H. Barks
1976, Water-Resources Investigations Report 33
A study of six small lakes, representative of those in the major physiographic regions of Missouri, shows variation in physical. chemical, and biological characteristics related to their location in the Slate. For example, because of climatic differences, ice cover and winter stratification are more prevalent in northern Missouri. Summer stratification...
Ground-water resources and geology of St. Croix County, Wisconsin
Ronald G. Borman
1976, Wisconsin Geological & Natural History Survey Information Circular 32
The increasing need for good-quality ground water in St. Croix County, caused by a steadily increasing population, can be met from the sand-and-gravel and sandstone aquifers. As much as 15 gallons per minute (0.95 litres per second) can be obtained from wells almost everywhere in the county. Yields of more...
Ground-water resources and geology of Walworth County, Wisconsin
Ronald G. Borman
1976, Wisconsin Geological & Natural History Survey Information Circular 34
Population growth in Walworth County, Wisconsin, requires an increasing amount of ground water. Good quality water is available from the sand-and gravel, Niagara, Galena-Platteville, and sandstone aquifers in the county. As much as 15 gallons per minute (0.95 liters per second) can be obtained from individual wells almost everywhere in...
Geology and ground-water resources of northern Mercer County, Pennsylvania
G. R. Schiner, G.E. Kimmel
1976, Water Resource Report 33
The Shenango and Stoneboro 15-minute quadrangles are in northwestern Pennsylvania and are about 60 miles north of Pitts burgh. These two quadrangles comprise the following 7%-minute quadrangles: Greenville West, Greenville East, Sharpsville, Fredonia, Hadley, New Lebanon, Jackson Center, and Sandy Lake. The area covered by the two quadrangles includes the...
Textural distribution of sea-floor sediments, south Texas Outer Continental Shelf
Gerald L. Shideler
1976, Journal of Research of the U.S. Geological Survey (4) 703-713
The general texture of sea-floor sediments along the south Texas Outer Continental Shelf was evaluated in terms of gravel, sand, silt, and clay components. The gravel component is quantitatively minor and is concentrated mainly in the southern sector; it consists, for the most part, of relict biogenic detritus dominated by...
Audio-magnetotelluric methods in reconnaissance geothermal exploration
D.B. Hoover, C. L. Long
1976, Conference Paper, Proceedings: second United Nations Symposium on the development and use of geothermal resources, San Francisco, California, USA, 20-29 May 1975
An audio-magnetotelluric (AMT) system has been developed by the U.S. Geological Survey for low-cost reconnaissance exploration of geothermal regions. This is an electromagnetic sounding technique in which the scalar or Cagniard resistivity is computed at 12 frequencies logarithmically spaced from 7.5 to 18 600 Hz. Our system uses natural source...
Rise of a variable-viscosity fluid in a steadily spreading wedge-shaped conduit with accreting walls
Arthur H. Lachenbruch, Manuel Nathenson
1976, Journal of Research of the U.S. Geological Survey (4) 181-188
Relatively rigid plates making up the outer 50 to 100 km of the Earth are steadily separating from one another along narrow globe-circling zones of submarine volcanism, the oceanic spreading centers. Continuity requires that the viscous underlying material rise beneath spreading centers and accrete onto the steadily diverging plates. It...
Regional geologic framework off northeastern United States
John Schlee, John C. Behrendt, John A. Grow, James M. Robb, Robert E. Mattick, P. T. Taylor, B. J. Lawson
1976, American Association of Petroleum Geologists Bulletin (60) 926-951
Six multichannel seismic-reflection profiles taken across the Atlantic continental margin off the northeastern United States show an excess of 14 km of presumed Mesozoic and younger sedimentary rocks in the Baltimore Canyon trough and 8 km in the Georges Bank basin.Beneath the continental rise, the sedimentary prism thickness exceeds 7...
Beacon Hill end moraine, Boston: new explanation of an important urban feature
Clifford A. Kaye
Donald R. Coates, editor(s)
1976, Book chapter, Urban Gomorphology (Geological Society of America, Special Paper 174)
The usefulness of geology to engineers is in direct proportion to how well it helps us predict the subsurface; these predictions, in turn, depend on our knowledge of the geomorphic processes that molded the terrain. The uncertainties of interpretation are particularly great in glaciated terrain because our understanding of both...
Geology and geophysics of the southern Raft River Valley geothermal area, Idaho, USA
Paul L. Williams, Don R. Mabey, Adel A. R. Zohdy, Hans D. Ackermann, Donald B. Hoover, Kenneth L. Pierce, Steven S. Oriel
1976, Conference Paper, Proceedings: second United Nations Symposium on the development and use of geothermal resources, San Francisco, California, USA, 20-29 May 1975
The Raft River valley, near the boundary of the Snake River plain with the Basin and Range province, is a north-trending late Cenozoic downwarp bounded by faults on the west, south, and east. Pleistocene alluvium and Miocene-Pliocene tuffaceous sediments, conglomerate, and felsic volcanic rocks aggregate 2 km in thickness. Large...
Characteristics of aquifers in the northern Uinta Basin area, Utah and Colorado
J. W. Hood
1976, Technical Publication 53
This report presents a part of the results of an investigation of the hydrology of the northern Uinta Basin area by the U.S. Geological Survey in cooperation with the Division of Water Rights, Utah Department of Natural Resources. The purpose of the report is to summarize the hydraulic and geohydrologic...
A geochemical study of oil in metalliferous veins, Idarado Mine, San Juan Mountains, Colorado
Peter M. Gerrild
1976, Journal of Research of the U.S. Geological Survey (4) 593-599
A tarry, benzene-soluble material is present in metal-rich veins in the Idarado mine, Ouray County, Colo., in an area not known to have petroleum resources. The material was compared chemically, spectometrically, and chromatographically with oils from four fields in the nearby Paradox basin. Each of these oil fields contains reservoir...
