A reconnaissance geochemical survey of the Allegheny Front and Hickory Creek Roadless Areas, Allegheny National Forest, Warren County, Pennsylvania
N. L. Hickling, Stanley P. Schweinfurth, Betty M. Adrian
1983, Open-File Report 83-5
A reconnaissance geochemical survey of the Allegheny Front and Hickory Creek Roadless Areas, Warren County, Pennsylvania, was made by members of the U.S. Geological Survey (USGS) to test for indistinct or unexposed mineral deposits that might be recognized by geochemical halos. Analyses using semiquantitative emission spectrography and atomic absorption for...
Geological and operational summary, Norton Sound COST No. 1 well, Norton Sound, Alaska
Ronald F. Turner, J.G. Bolm, C.M. McCarthy, D. A. Steffy, Paul Lowry, T.O. Flett
1983, Open-File Report 83-124
Title 30, Code of Federal Regulations (CFR), paragraph 251.14 stipulates that geological data and processed geological information obtained from Deep Stratigraphic Test wells drilled on the Outer Continental Shelf (OCS) be made available for public inspection 60 calendar days after the issuance of the first Federal lease within 50 nautical...
Geochemical evaluation of felsic plutonic rocks in the eastern and southeastern Arabian Shield, Kingdom of Saudi Arabia
E. A. Du Bray, James E. Elliott, D. B. Stoeser
1983, Open-File Report 83-369
In a geochemical evaluation of the eastern and southeastern Arabian Shield, which included collection of 696 rock samples and 694 pan concentrate samples, a province of tin-anomalous granitoid plutons was defined. Pan concentrates collected in and around these plutons were enriched in tin and tungsten relative to the concentrate population....
Holocene sedimentation in Richardson Bay, California
Cathy L. Connor
1983, Open-File Report 83-312
Examination of foraminifers, diatoms, ostracodes, clay mineralogy, and sediment-size variation from 9 borehole sites along the salt-marsh margins of Richardson Bay reveals a record of gradual infilling of fine-grained estuarine sediments. Over the past 10,000 years this area was transformed from a V-shaped Pleistocene stream valley to a flat-floored arm...
Geohydrology and water resources of the Papago Farms-Great Plain area, Papago Indian Reservation, Arizona, and the upper Rio Sonoyta area, Sonora, Mexico
K.J. Hollett
1983, Open-File Report 83-774
The Papago Farms-Great Plain and upper Rio Sonoyta study area includes about 490 square miles in south-central Arizona and north-central Sonora, Mexico. In the study area 23,700 acre-feet of ground water from the basin-fill deposits was used to irrigate more than 5,000 acres in 1981. Surface water is not a...
GRANNY, a data bank of chemical analyses of Laramide and younger high-silica rhyolites and granites from Colorado and north-central New Mexico
Celia H. Steigerwald, Felix E. Mutschler, Steve Ludington
1983, Open-File Report 83-516
GRANNY is a data bank containing information on 507 chemically analyzed Laramide or younger high-silica rhyolites and granites from Colorado and north-central New Mexico. The data were compiled from both published and unpublished sources. The data bank is designed to aid in the recognition of igneous rocks with a high...
Geology and resources of the Andersonville, Georgia, kaolin and bauxite district
Harland E. Cofer, John Phillip Manker
1983, Open-File Report 83-580
The kaolin and kaolin-rich sediments of the Andersonville district were deposited in an estuary environment with restricted circulation and little tidal or longshore current influence. Micaceous kaolinitic clays were deposited during late Paleocene time on broad, shallow water flats between deeper water distributary channels in the estuarine system. During the...
Hydrology of Area 1, eastern coal province, Pennsylvania [West Branch Susquehanna River, Sinnemahoning Creek, Upper Juniata River, Clearfield Creek]
William J. Herb, Deborah E. Brown, Lewis C. Shaw, Albert E. Becher
1983, Open-File Report 83-223
Provisions of the Surface Mining Control and Reclamation Act of 1977 recognized a nationwide need for hydrologic information in mined and potentially mined areas. This report is designed to be useful to mine owners, operators, regulatory authorities, citizens groups, and others by presenting information on existing hydrologic conditions and by...
A seismic study of Yucca Mountain and vicinity, southern Nevada; data report and preliminary results
L.R. Hoffman, W. D. Mooney
1983, Open-File Report 83-588
From 1980 to 1982, the U.S. Geological Survey conducted seismic refraction studies at the Nevada Test Site to aid in an investigation of the regional crustal structure at a possible nuclear waste repository site near Yucca Mountain. Two regionally distributed deployments and one north-south deployment recorded nuclear events. First arrival...
Nonparametric tests for trends in water-quality data using the statistical analysis system
Charles G. Crawford, James R. Slack, Robert M. Hirsch
1983, Open-File Report 83-550
Two nonparametric procedures to test for trends in water-quality data (SEASKEN AND SEASRS) have been developed for the Statistical Analysis System* (SAS). The procedure SEASKEN tests for a monotonic trend in time by a modified form of Kendall's tau, the Seasonal Kendall test. The procedure SEASRS tests for a step...
Floods from small drainage basins in Alaska
Stanley H. Jones
1983, Open-File Report 83-258
Flood peak-stage and associated discharge data collected since 1963 in small (generally less than 100 square miles) drainage areas in Alaska are presented in tabular and graphical form. The report also contains table of computed magnitudes of floods at selected recurrence intervals (2, 5, 10, 25, and 50 years) for...
