Stratigraphic framework and distribution of lignite on Crowleys Ridge, Arkansas
Charles R. Meissner
1983, Open-File Report 83-609
The purpose of this report is to establish a stratigraphic framework of lignite beds and associated strata of Crowleys Ridge, Arkansas. Drill hole data provided by the Arkansas Geological Commission is used in the synthesis and interpretation. Areas containing lignite of potential resource value are also delineated. To illustrate the...
Ground-water quality data for Oklahoma, 1981
Dale M. Ferree
1983, Open-File Report 83-686
The U.S. Geological Survey has collected data on Oklahoma's ground-water resources since 1934. Most of these data were collected as part of specific ground-water studies conducted in cooperation with various Federal, State, and local agencies. Ground-water quality data, as well as data on construction, yield, water levels, and other physical...
Density, porosity, and magnetic properties of rock specimens from southwestern Arizona
Douglas P. Klein, Gordon R. Johnson
1983, Open-File Report 83-808
Petrophysical data on 364 rock specimens from southwest Arizona are tabulated and summarized by major rock suites for that part of southwest Arizona covered by the Ajo 1? x 2? quadrangle and the Papago Indian Reservation. Data for 202 of these specimens are new and previously unreported. The tabulation also...
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....
Summary of water withdrawals in the United States, 1950-80
William B. Mann, Wayne B. Solley, Edith B. Chase
1983, Open-File Report 83-207
Estimated use of water in the United States increased from 180 bgd (billion gallons per day) in 1950 to 450 bgd in 1980. During this same time population increased from about 150 million to about 230 million. Data on consumptive use are not available for the first decade of the...
Preliminary stage-discharge relations for Tombigbee River at Gainesville Dam, near Gainesville, Alabama
G. H. Nelson, C. O. Ming
1983, Open-File Report 83-942
The construction of Gainesville Dam and other related channel alterations, completed in 1979, has resulted in changes to the stage-discharge relations in the vicinity. The lack of current-meter measurements, coupled with backwater conditions, makes definition of a single stage-discharge relation impossible. However, limit curves can be defined that would encompass...
Ground-water data for Georgia, 1982
H.R. Stiles, S.E. Matthews
1983, Open-File Report 83-678
Continuous water level records from 105 wells, and more than 2 ,000 water level measurements made in Georgia during 1982 provided the basic data for this report. Selected wells illustrate the effects that changes in recharge and pumpage have had on the various groundwater resources in the State. Daily mean...
Comparison of the chemical characteristics of the uranium deposits of the Morrison Formation in the Grants uranium region, New Mexico
C.S. Spirakis, C. T. Pierson
1983, Open-File Report 83-380
Statistical treatment of the chemical data of samples from the northeast Church Rock area, Ruby deposit, Mariano Lake deposit, and the Ambrosia Lake district indicates that primary ore-forming processes concentrated copper, iron, magnesium, manganese, molybdenum, selenium, vanadium, yttrium, arsenic, organic carbon, and sulfur, along with uranium. A barium halo that...
Vegetation and climates of the last 45,000 years in the vicinity of the Nevada Test Site, south-central Nevada
W. G. Spaulding
1983, Open-File Report 83-535
Paleoclimatic reconstructions for the Nevada Test Site, spanning the last 45,000 years, are based on plant macrofossil assemblages from radiocarbonated packrat (Neotoma spp) middens from south-central Nevada. The temperature regime during the Wisconsin glacial age, from before about 45,000 years ago until about 12,000 years ago, was characterized by lower...
Laboratory safety handbook
E.L. Skinner, C.A. Watterson, J.C. Chemerys
1983, Open-File Report 83-131
Safety, defined as 'freedom from danger, risk, or injury,' is difficult to achieve in a laboratory environment. Inherent dangers, associated with water analysis and research laboratories where hazardous samples, materials, and equipment are used, must be minimized to protect workers, buildings, and equipment. Managers, supervisors, analysts, and laboratory support personnel...
Selected hydrologic data, Kolob-Alton-Kaiparowits coal-fields area, south-central Utah
Gerald G. Plantz
1983, Open-File Report 83-871
The Kolob-Alton-Kaiparowits coal-field area (pi. 1) includes about 4,500 square miles in parts of the Colorado River Basin and the Great Basin. The area varies in altitude from less than 4,000 to more than 10,000 feet, and is comprised chiefly of plateaus, benches, and terraces that are dissected by deep,...
Comparison of abundances of chemical elements in mineralized and unmineralized sandstone of the Brushy Basin Member of the Morrison Formation, Smith Lake District, Grants uranium region, New Mexico
C. T. Pierson, C.S. Spirakis, J. F. Robertson
1983, Open-File Report 83-818
Statistical treatment of analytical data from the Mariano Lake and Ruby uranium deposits in the Smith Lake district, New Mexico, indicates that organic carbon, arsenic, barium, calcium, cobalt, copper, gallium, iron, lead, manganese, molybdenum, nickel, selenium, strontium, sulfur, vanadium, yttrium, and zirconium are concentrated along with uranium in primary ore....
