Analytical results for 89 water samples from the Papago Indian Reservation, Arizona
Walter H. Ficklin, Wheeler Ashton, D. J. Preston, G.A. Nowlan
1978, Open-File Report 78-1092
Eighty-nine water samples were collected from the Papago Indian Reservation during 1977 and 1978 as a part of a mineral resource study. Each sample was analyzed for copper, zinc, molybdenum, arsenic, uranium, sodium, potassium, calcium, magnesium, bicarbonate, sulfate, chloride, fluoride, and silica. Temperature, pH, and specific conductance were also measured....

Geochemical studies of the Rolla, Mo., 1° x 2° quadrangle were begun in 1977 as a part of a joint multidisciplinary study of the quadrangle by the U.S. Geological Survey and the Division of Geology and Land Survey, Missouri Department of Natural Resources. The study is to assess the mineral...
Reconnaissance evaluation of water resources for hydraulic coal mining, Grand Hogback coal field: Garfield and Rio Blanco Counties, Colorado
William M. Alley, Linda J. Britton, Elaine L. Boyd
1978, Open-File Report 78-885
Surface-water and ground-water data were compiled for the parts of the Colorado River and the White River basins in and adjacent to the Grand Hogback coal field. The data were evaluated to assess the quantity and quality of water resources available in the area for use in hydraulic coal mining....
Selected hydrologic data, 1931-77, Wasatch Plateau-Book Cliffs coal-fields area, Utah
K.M. Waddell, H.L. Vickers, Robbin T. Upton, P. Kay Contratto
1978, Open-File Report 78-121
The Wasatch Plateau-Book Cliffs coal-fields area in east-central Utah includes a significant part of the State's coal resources and is currently (1977) the most active coal-mining area in the State.This report presents data gathered by the U.S. Geological Survey as part of a hydrologic reconnaissance carried out during the period...
The Potential for Prophyry Copper-Molybdenum Deposits in the Eastern United States
Robert Gordon Schmidt
1978, Professional Paper 907-E
Several significant porphyry-type deposits of Paleozoic age are known in New England and eastern Canada. Disseminated copper-molybdenum deposits of Paleozoic age are in the Southeastern United States, and copper is produced from porphyry-type deposits of both Precambrian and Paleozoic age in eastern Canada. Although these old deposits are surely less...
Effects of urbanization on streamflow and sediment transport in the Rock Creek and Anacostia River basins, Montgomery County, Maryland, 1962-74
Thomas H. Yorke, William J. Herb
1978, Professional Paper 1003
Land use, precipitation, streamflow, and sediment discharge data were collected from nine small drainage basins in Montgomery County, Maryland, to evaluate runoff and sediment response to sediment-control practices in areas undergoing urban development. Drainage basins ranged in size from 0.35 to 21.1 sq mi and land use ranged from rural...
Ground-water levels and quality data for Georgia, 1977
Water Resources Division, U.S. Geological Survey
1978, Open-File Report 79-213
This report begins a publication format that will present annually both water-level and water-quality data. In this format the information is presented in two-page units: the left page includes text which summarizes the information for an area or subject and the right page consists of one or more illustrations. Daily...
Water-quality records for the Hubbard Creek watershed, Texas, October 1974 - September 1976
Helen J. Davidson
1978, Open-File Report 78-98
The U.S. Geological Survey, in cooperation with the West Central Texas Municipal Water District and the Texas Department of Water Resources, is conducting a continuing program to determine the chemical quality of surface waters in the Hubbard Creek watershed. This report provides a compilation of the records for the period...
Estimated oil and gas reserves, Gulf of Mexico Outer Continental Shelf, January 1, 1977
Floyd T. Bryan, John H. Knipmeyer, E. Kenneth Schluntz
1978, Open-File Report 78-87
As of January 1, 1977, nearly 35 trillion cubic feet of gas and about 2.7 billion barrels of oil* are estimated to be the remaining reserves in 294 fields in the Gulf of Mexico Outer Continental Shelf off Texas and Louisiana. Twenty-seven additional fields, discovered since January 1, 1976, in...
Radiometric results and areal distribution for granitic samples from the Granite Mountains, Wyoming
John S. Stuckless, Carl M. Bunker, George Van Trump, Charles A Bush
1978, Open-File Report 78-803
Analyses of surface samples from the Granite Mountains, Wyoming, generally agree with the findings from drilling at two different localities. The dominant Precambrian granitic rock type is the biotitic phase of the granite of Lankin Dome. This rock type is characterized by high potassium and anomalously high thorium concentrations, and...
1978 Water Quality Laboratory services catalog
Linda C. Friedman
1978, Open-File Report 78-502
The information in this catalog is provided to assist field personnel in the selection of determinations, the estimation of costs, the calculation of sample volume requirements, the identification of the necessary sample treatment and in the evaluation of the precision of the laboratory data.

Historic ground failures in Northern California triggered by earthquakes
T. Leslie Youd, Seena N. Hoose
1978, Professional Paper 993
A major source of earthquake-related damage and casualties in northern California has been ground failures generated by the seismic shaking, including landslides, lateral spreads, ground settlement, and surface cracks. The historical record shows that, except for offshore shocks, the geographic area affected and the quantity and general severity of ground...
Field determination of vertical permeability to air in the unsaturated zone
Edwin P. Weeks
1978, Professional Paper 1051
The vertical permeability to air of layered materials in the unsaturated zone may be determined from air pressure data obtained at depth during a period when air pressure is changing at land surface. Such data may be obtained by monitoring barometric pressure with a microbarograph or surveying altimeter and simultaneously...
