Continuous seismic-reflection survey defining shallow sedimentary layers in the Charlotte Harbor and Venice areas, southwest Florida
R. M. Wolansky, F.P. Haeni, R.E. Sylvester
1983, Water-Resources Investigations Report 82-57
A continuous marine seismic-reflection survey system was used to define the configuration of shallow sedimentary layers underlying the Charlotte Harbor and Venice areas, southwest Florida. Seismic profiling was conducted over a distance of about 57 miles of Charlotte Harbor, the Peace and Myakka Rivers, and the Intracoastal Waterway near Venice...
Data from the surface-water hydrologic investigations of the Hay Creek Study Area, Montana, and the West Branch Antelope Creek Study Area, North Dakota, October 1976 through April 1982
Douglas G. Emerson, Steven W. Norbeck, Kelvin L. Boespflug
1983, Open-File Report 83-136
Data are provided for the Hay Creek study area near Wibaux, Mont., and the West Branch Antelope Creek study area near Beulah, N. Dak. The report contains data on the following: Air temperature, relative humidity, wind direction, wind run, solar radiation, precipitation, soil temperature, snowpack temperature, snowpack density and water...
Preliminary assessment of in-situ geomechanical characteristics in drill hole USW G-1, Yucca Mountain, Nevada
William L. Ellis, Henri S. Swolfs
1983, Open-File Report 83-401
Observations made during drilling and subsequent testing of the USW G-1 drill hole, Yucca Mountain, Nevada, provide qualitative insights into the in- situ geomechanical characteristics of the layered tuff units penetrated by the hole. Substantial drilling-fluid losses, and the occurrence of drilling-induced fracturing, are understandable in terms of the low,...
Peralkaline and peraluminous granites and related mineral deposits of the Arabian Shield, Kingdom of Saudi Arabia
James E. Elliott
1983, Open-File Report 83-389
In the Precambrian Arabian Shield, granitoid plutonic rocks are widespread and range in age from 800 to 550 Ma old; but the mineral-resource potential associated with these plutonic rocks is restricted mainly to the younger, postorogenic granites. Two granite types of current economic interest are zirconium- niobium-enriched per alkaline granites...
Description of slides showing aeromagnetic and gravity data for regional mineral exploration in Colorado, New Mexico, and Arizona
Douglas P. Klein
1983, Open-File Report 83-703
Examples of aeromagnetic and gravity data over 1? x 2? areas are presented for regions near the Cripple Creek mining area, Colorado, and the Lordsburg-Tyrone-Silver City mining areas, southern New Mexico and Arizona. These data indicate broad crustal structures and compositional variations that are marked by magnetization and density contrasts....
Ground-water exploration in the South Kohala district, Hawaii County, Hawaii, using vertical electrical sounding
James P. Kauahikaua, Dallas B. Jackson
1983, Open-File Report 83-67
Ten deep electrical resistivity soundings were completed across the island of Hawai?i near the town of Waimea in an effort to locate high-level, dike-impounded water. The resistivity data did not support the existence of a high-level water occurrence. Instead, the data show that a thick basal fresh-water lens underlies the...
Water resources data for Connecticut, water year 1982
C.E. Thomas Jr., T.B. Shepard, I.S. Gasperini, S.E. Wing
1983, Water Data Report CT-82-1
Water resources data for the 1982 water year for Connecticut consist of records of stage, discharge, and water quality of streams; contents and water quality of lakes and reservoirs; and water levels and water quality of ground-water wells. This volume contains records for water discharge at 48 gaging stations; storm...
Bryozoan fauna of the Upper Clays Ferry, Kope, and Lower Fairview formations (Edenian, Upper Ordovician) at Moffett Road, northern Kentucky
Olgerts L. Karklins
1983, Open-File Report 83-21
The geology, water movement, and sediment characteristics in the upstream part of the Spring River basin have been appraised, to assist the U.S. EPA in their study of dioxin contamination in the area. The U.S. Environmental Protection Agency has confirmed that the dioxin compound, TCDD (2,3,7 ,8-tetrachlorodibenzo-p-dioxin), is present in...
Analyses and descriptions of geochemical samples from the Rich Mountain Roadless Area, Fannin and Gilmer counties, Georgia
C.M. Sears, M. P. Foose, G.W. Day, M.S. Ericksen
1983, Open-File Report 83-658
Semi-quantitative spectrographic analyses for 31 elements on rock, soil, fine-grained stream sediment, bulk stream sediment, and panned stream sediment samples collected in the Rich Mountain Roadless Area, Fannin and Gilmer Counties, Georgia, are reported here. Atomic absorption analyses for gold and fluorometric analyses for uranium are also reported. Brief descriptions...
Subsurface storage of freshwater in south Florida: A prospectus
M. L. Merritt, F.W. Meyer, W. H. Sonntag, D. J. Fitzpatrick
1983, Water-Resources Investigations Report 83-4214
A method of increasing storage capacity for freshwater in south Florida is to use brackish artesian aquifers as reservoirs. In this way, water deficiencies occurring during the annual dry season can be offset by surplus water obtained during the wet season and injected underground. Most of south Florida is underlain...
Aquifer systems in the Great Basin region of Nevada, Utah, and adjacent states: A study plan
James R. Harrill, Alan H. Welch, David E. Prudic, James M. Thomas, Rita L. Carman, Russell W. Plume, Joseph S. Gates, James L. Mason
1983, Open-File Report 82-445
The Great Basin Regional Aquifer Study includes about 140,000 square miles in parts of Nevada, Utah, California, Idaho, Oregon, and Arizona. Within that area, 240 hydrographic areas occupy structural depressions formed primarily by basin-and-range faulting. The principal aquifers are in basin- fill deposits; however, permeable carbonate rocks underlie valleys in...
Aeromagnetic map and interpretation of geophysical data from the Condrey Mountain Roadless Area, Siskiyou County, California
R.C. Jachens, W.P. Elder
1983, Miscellaneous Field Studies Map 1540-B
The Condrey Mountain Roadless Area lies within the Klamath Mountains geologic province, a province composed of four eastward-dipping imbricate thrust slices or belts consisting predominantly of marine arc-related volcanic and sedimentary rocks, but also including significant amounts of ultramafic and other ophiolitic rocks (Irwin, 1981). From west to east the...
