A revised version of Graphic Normative Analysis Program (GNAP) with examples of petrologic problem solving
J. S. Stuckless, G. VanTrump
1979, Open-File Report 79-1237
A revised version of Graphic Normative Analysis Program (GNAP) has been developed to allow maximum flexibility in the evaluation of chemical data by the occasional computer user. GNAP calculates ClPW norms, Thornton and Tuttle's differentiation index, Barth's cations, Niggli values and values for variables defined by the user. Calculated values...
Water-resources investigations of the U.S. Geological Survey in Montana, October 1978 through September 1979
Water Resources Division, U.S. Geological Survey
1979, Open-File Report 79-418
The report describes water-resources investigations of the U.S. Geological Survey in Montana, October 1978 through September 1979. Programs consist of (1) collecting hydrologic data on a continuing basis, (2) conducting water-resources appraisals of surface and ground water, (3) conducting supportive research in hydrology and related fields, (4) disseminating water data...
Directory to Federal, State, and local OCS-related activities and contacts
Mitre Corporation
1979, Open-File Report 79-1481
This directory identifies specific Federal, state, and local agencies involved with oil and gas activities on the Outer Continental Shelf (OCS). Current agency responsibilities and the mechanisms used for interacting with OCS activities are outlined in three groupings: (a) an overview of major Federal activities (Chapter 2) and the mechanisms...
Statistical summaries of surface-water-quality data for selected sites in Oklahoma, through the 1975 water year
J. K. Kurklin
1979, Open-File Report 79-219
Statistical summaries of surface-water-quality data for 47 streams in Oklahoma have been compiled. Data for the period of record through the 1975 water year at each site were used to develop regression equations for specific conductance-constituent relationships for calcium, magnesium, sodium, sodium plus potassium, bicarbonate, sulfate, chloride, silica, and dissolved...
January 1979 water levels, and data related to water-level changes, western and south-central Kansas
Marilyn E. Pabst
1979, Open-File Report 79-925
This report contains hydrologic data on water-level measurements in observation wells in western and south-central Kansas. The measurements were made in mid-winter, mostly in January, when pumping was minimal and water levels had recovered from the effects of pumping during the previous irrigation season. This report also provides basic hydrologic...
Plan of study for the northern Great Plains regional aquifer-system analysis in parts of Montana, North Dakota, South Dakota, and Wyoming
George A. Dinwiddie
1979, Water-Resources Investigations Report 79-34
The Northern Great Plains, an area of about 250,000 square miles in parts of Montana, North Dakota, South Dakota, and Wyoming, is underlain by an accumulation of sediments eroded from the Black Hills and from mountains to the west. Principal aquifers are areally extensive beds of sandstone within these sedimentary...
Tertiary volcanic rocks of the Mineral Mountain and Teapot Mountain quadrangles, Pinal County, Arizona
William J. Keith, Ted G. Theodore
1979, Open-File Report 79-716
The widespread distribution of Tertiary volcanic rocks in south-central Arizona is controlled in part by prevolcanic structures along which volcanic vents were localized. Volcanic rocks in the Mineral Mountain and Teapot Mountain quadrangles mark the site of a major northwest-trending structural hingeline. This hingeline divides an older Precambrian X terrane...
Streamflow Estimates in Selected Wisconsin Streams
R.P. Novitzki
1979, Open-File Report 79-1282
The Wisconsin Department of natural Resources needs streamflow information in lake basins where lake-rehabilitation programs are implemented but where long-term stream-gaging stations are not justified. The U.S. Geological Survey provided streamflow estimates for 24 streams in Wisconsin. The estimates were made by the use of (1) midmonthly measurements, (2) basin...
Portable field kit for determining uranium in water
John B. McHugh
1979, Open-File Report 79-429
The pressing need for on-site field analyses of the uranium content of surface and ground waters has promoted the development of a simple, light-weight, relatively cheap, portable kit to make such determinations in the field. Forty to sixty water samples per day can be analyzed for uranium to less than...
Baseline water quality of Iowa's coal region
Larry J. Slack
1979, Open-File Report 79-980
To assist the Iowa Department of Environmental Quality in determining the effects that coal mining and attendant activities will have on the water quality of Iowa streams, the U.S. Geological Survey collected three sets of water-quality samples (representative of high, average, and low streamflow) in the White Breast, English,aand Cedar...
