Regional magnetic and gravity features of the Gibson Dome area and surrounding region, Paradox Basin, Utah: A preliminary report
T.G. Hildenbrand, R.P. Kucks
1983, Open-File Report 83-359
Analyses of regional gravity and magnetic anomaly maps have been carried out to assist in the evaluation of the Gibson Dome area as a possible repository site for high-level radioactive waste. Derivative, wavelength-filtered, and trend maps were compiled to aid in properly locating major geophysical trends corresponding to faults, folds,...
A reconnaissance geochemical survey of the Clarion River Roadless Area, Allegheny National Forest, Elk County, Pennsylvania
N. L. Hickling, Stanley P. Schweinfurth, Betty M. Adrian
1983, Open-File Report 83-22
Semiquantitative emission spectrographic analyses for 31 elements were determined on 9 stream-sediment samples and 18 bedrock samples from the Clarion River Roadless Area, Elk County, Pennsylvania. All sample localities are given in Universal Transverse Mercator (UTM) coordinates. Brief descriptions of bedrock samples are also included. Rocks analyzed are mostly sandstone,...
An aeromagnetic interpretation of eleven map sheets, scale 1:250,000, in the southern Najd and part of the southern Tuwayq quadrangles, Kingdom of Saudi Arabia
Andrew Griscom
1983, Open-File Report 82-1048
Eleven magnetic interpretation maps (scale 1:250,000) have been prepared for the area .of. exposed crystalline rocks in the Southern Najd and part of the Southern Tuwayq quadrangles (scale 1:500,000) from available published data. Boundaries of a variety of rock units that produce distinctive magnetic anomalies .or anomaly patterns are delineated....
Microcumpter computation of water quality discharges
Dennis R. Helsel
1983, Open-File Report 82-901
A fully prompted program (SEDQ) has been developed to calculate daily and instantaneous water quality (QW) discharges. It is written in a version of BASIC, and requires inputs of gage heights, discharge rating curve, shifts, and water quality concentration information. Concentration plots may be modified interactively using the display screen....
Distribution of selected chemical constituents in water from the Floridan aquifer, Southwest Florida Water Management District
M.A. Corral Jr.
1983, Water-Resources Investigations Report 83-4041
Generalized maps showing variations in concentration of chlorides, sulfates, hardness, and dissolved solids in the Floridan aquifer have been prepared as part of a cooperative program with the Southwest Florida Water Management District. This report covers 10 counties and parts of 6 others comprising the District. Data used to develop...
Hydrogeologic and water-quality characteristics of the St. Peter aquifer, Southeast Minnesota
J. F. Ruhl, R. J. Wolf
1983, Water-Resources Investigations Report 83-4200
Quality of water in the St. Peter aquifer is generally acceptable for most uses. Sulfate concentrations increase toward the southwestern part of the aquifer because of highly mineralized leakage from overlying Cretaceous deposits. Concentrations of sodium, magnesium, and sulfate generally increase to the west, and those of calcium, bicarbonate, and...
Water-resources investigations of the U.S. Geological Survey in the Souris-Red Rivers basin in Minnesota, North Dakota, and South Dakota
J. E. Heisel
1983, Open-File Report 83-218
Information obtained on water resources by Federal and State agencies in the Souris-Red Rivers basin along the Canadian border in the midwestern United States is available for analysis to address flood, drought, and supply problems. It consists of streamflows, ground water measurements, and quality of water determinations. This summary contains...
Water-resources investigations of the U.S. Geological Survey in Wyoming, fiscal years 1981 and 1982
S. L. Green
1983, Open-File Report 83-254
This report contains lists and location maps of streamflow and reservoir stations, peak-flow partial-record stations, water quality stations, sediment stations, and ground-water stations that are currently being operated. Water-resources appraisal projects in Wyoming are also described, including many that are related to development of energy resources. The general locations of...
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...
