Sediments, structural framework, petroleum potential, environmental conditions, and operational considerations of the United States South Atlantic Outer Continental Shelf
Water Resources Division, U.S. Geological Survey
1975, Open-File Report 75-411
The area designated for possible oil and gas lease sale in Bureau of Land Management memorandum 3310 #43 (722) and referred to therein as part of the United States South Atlantic Outer Continental Shelf (OCS) contains about 98,000 square kilometres of the continental margin seaward of the 3 mile offshore...
Geochemical soil studies in the Cotter Basin area, Lewis and Clark County, Montana
D. J. Grimes, Robert L. Earhart
1975, Open-File Report 75-72
Geochemical sampling in an area of abnormal vegetation in the Cotter basin area, Lewis and Clark County, Montana, shows anomalously high concentrations of Cu, Pb, Ag, Zn, and Au in the soil. The singular presence of a particular plant species growing in the highly anomalous zone merits further investigation for...
United States Geological Survey's hydrogeological research programs and plans related to disposal of radioactive waste into geologic formations
George D. DeBuchananne, William Stephens Twenhofel
1975, Open-File Report 75-626
The Geological Survey, United States Department of Interior, has cooperated with the United States Energy Research and Development Administration, formerly the Atomic Energy Commission, for more than 30 years on research related to the disposal of radioactive waste into geological formations. Results of most of this research effort have been...
Ground water in the Verdigris River basin, Kansas and Oklahoma
Stuart Wesley Fader, Robert B. Morton
1975, Open-File Report 75-365
Ground water in the Verdigris River basin occurs in consolidated rocks and unconsolidated deposits ranging in age from Mississippian to Quaternary. Water for municipal, industrial, and irrigation supplies generally can be obtained in limited quantities from the alluvial deposits in the stream valleys. Except for water in the alluvial deposits...
Analysis of operational plan for Lake Chippewa near Winter, Wisconsin
William R. Krug
1975, Open-File Report 75-487
Historical inflows into Lake Chippewa for 39 years of record were analyzed to determine the possibility of operating the flowage within a 2-foot (0.6-metre) range of stage while maintaining a minimum discharge of 57 cubic feet per second (1.6 cubic metres per second) and limiting the maximum discharge to 7,000...
Antimony deposits of Quetta-Pishin District, Quetta Division, Pakistan
F.L. Klinger, John J. Matzko, S.H. Abbas
1975, Open-File Report 75-161
Vein-type deposits of antimony ore, consisting of stibnite and quartz, are found in the hanging wall of faults cutting slate of probable Miocene age 15 miles northeast of Qila Abdullah in the Quetta-Pishin District. The ore is associated with zones of oxidized slate. Although the known deposits are small, the...
Magnitude and frequency of floods in Washington
J. E. Cummans, Michael R. Collings, Edmund George Nasser
1975, Open-File Report 74-336
Relations are provided to estimate the magnitude and frequency of floods on Washington streams. Annual-peak-flow data from stream gaging stations on unregulated streams having 1 years or more of record were used to determine a log-Pearson Type III frequency curve for each station. Flood magnitudes having recurrence intervals of 2,...
Uranium in phosphate rock
James Bachelder Cathcart
1975, Open-File Report 75-321
Uranium is a trace constituent of all apatites in amounts that typically range from <0.001 to 0.003 percent for guano and guano-derived deposits; from 0.001 to 0.010 percent for igneous apatites; from 0.005 to 0.030 percent for marine phosphorites. Uranium may be enriched to as much as 0.05 percent in...
Sediment characteristics of streams in the eastern Piedmont and western Coastal Plain regions of North Carolina
Clyde E. Simmons
1975, Open-File Report 75-291
The sediment-transport characteristics of streams were determined in a 6,000-square-mile (15,500-square-kilometre) area of the Coastal Plain and Piedmont regions of eastern North Carolina during 1969-73. The study covered all or parts of 21 counties and included data for 28 sediment-sampling stations located in parts of 4 major river basins, the...
Relation of precipitation to annual ground-water recharge in the Edwards Aquifer, San Antonio area, Texas
Celso Puente
1975, Open-File Report 75-298
Annual recharge data obtained from historical records and mean-annual precipitation data computed from rainfall records were used to develop simple linear-regression equations for use in estimating annual recharge for seven subbasins in the San Antonio area. Adjustments were made to the precipitation parameter to account for the effects of year-end...
