Generalized thickness of the surficial deposits above the confining bed overlying the Floridan Aquifer, Southwest Florida Water Management District
R. M. Wolansky, R. M. Spechler, Anthony Buono
1979, Open-File Report 79-1071
This map report presents the thickness of the surficial deposits overlying the upper confining bed of the Floridan aquifer in the Southwest Florida Water Management District. The surficial deposits range in thickness from less than 25 feet in the western part of the district to greater than 250 feet in...
Geochemical and generalized geologic map showing distribution and abundance of antimony and niobium in stream sediments, Chandalar 1° by 3° quadrangle, Alaska
S.P. Marsh, D.E. Detra, S.C. Smith
1979, Miscellaneous Field Studies Map 878-H
This geochemical map shows the distribution and abundance of antimony (Sb) and niobium (Nb) in -80 mesh (177 micrometers) stream sediment samples in the Chandalar quadrangle, Alaska. The map is one of a series of geochemical maps that together with the background information circular (Reiser and others, 1978) comprise the folio...
Hydrologic data for urban studies in the Fort Worth, Texas, metropolitan area, 1977
R.M. Slade Jr., J.M. Taylor, D.L. Haynes
1979, Open-File Report 79-216
Hydrologic investigations of urban areas in Texas were begun by the U.S. Geological Survey in 1954. These investigations are now in progress in several major metropolitan areas including Austin, Dallas, Dallas County, Fort Worth, Houston, and San Antonio.In October 1968, the Geological Survey, in cooperation with the city of Fort...
Paleontologic and stratigraphic relations of phosphate beds in Upper Cretaceous rocks of the Cordillera Oriental, Colombia
Edwin K. Maughan, Francisco Zambrano O., Pedro Mojica G., Jacob Abozaglo M., Fernando Pachon P., Raul Duran R.
1979, Open-File Report 79-1525
Phosphorite crops out in the Cordillera Oriental of the Colombian Andes in rocks of Late Cretaceous age as strata composed mostly of pelletal carbonate fluorapatite. One stratum of Santonian age near the base of the Galembo Member of the La Luna Formation crops out at many places in the Departments...
Summary appraisals of the nation's ground-water resources – Pacific Northwest region
Bruce L. Foxworthy
1979, Professional Paper 813-S
The Pacific Northwest Region's ground-water reservoirs are capable of providing large additional fresh-water supplies; these reservoirs become more important as undeveloped surface-storage sites and unapportioned surface-water supplies dwindle. Withdrawals of fresh water from all surface and underground sources are increasing; they may rise from the rate of 30 billion gallons...
Summary appraisals of the nation's ground-water resources – Lower Mississippi region
J. E. Terry, R. L. Hosman, C. T. Bryant
1979, Professional Paper 813-N
The Lower Mississippi Region comprises an area of 102,400 square miles (265,200 square kilometers). Almost all this area is in the physiographic province known as the Gulf Coastal Plain. Three small areas on the northwest boundary of the region are in the Interior Highlands. The Lower Mississippi Region has an abundance...
Direct analysis of RDX and TNT in water by high-performance liquid chromatography
D.F. Goerlitz
1979, Open-File Report 79-916
A method for the determination of RDX (1,3,5-trinitro-1,3,5-triazacyclohexane) and TNT (2,4,6-trinitrotoluene) directly in water is given. The high-performance liquid chromatographic technique permits detection down to 0.1 microgram per liter in filtered water. No ancillary extraction or concentrating procedures are used....
Resource report for proposed OCS lease sale no. 70, St. George Basin, shelf area, Alaska
Michael S. Marlow, J.V. Gardner, T.L. Vallier, H. McLean, E. W. Scott, M.B. Lynch
1979, Open-File Report 79-1650
St. George basin is a long (300 km), narrow (30-50 km) graben whose long axis strikes northwestward, parallel to the continental margin of the southern Bering Sea. Located near the Pribilof Islands, and beneath the virtually featureless Bering Sea shelf, the basin is filled with more than 10 km of...
Gazetteer of coal-mine lakes in southwestern Indiana
Linda L. Bobo
1979, Open-File Report 79-1639
This gazetteer is a catalog of lakes formed by surface coal mining in southwestern Indiana that are 0.5 acre or larger and in nonactive mine areas. Approximately 1,000 of the lakes are listed by 7.5-minute quadrangle topographic-map name, lake-identification number, latitude and longitude, and county. Other data given are shape...
Trace metals in surface sediments of the Mid-Atlantic Continental Shelf
Michael H. Bothner
1979, Open-File Report 79-843
The concentrations of 9 trace metals (Fe, Pb,Zn, Ba, Cu, Ni, V, Cr, and Cd) in surficial Continental Shelf sediments are low compared to the concentrations reported for average crustal rocks. No evidence for the accumulation of anthropogenic trace metals was found at the 51 locations sampled in this study....
