Thrust fault zones in the Allegheny Plateau of north-central Pennsylvania
Howard A. Pohn, Terri L. Purdy
1979, Open-File Report 79-1604
Field investigations in the Williamsport Valley identify lineaments found on Landsat III images, have shown the presence of six discrete fault zones that strike subparallel to the trend of the Appalachian folds. These zones range from 0.5 to 1.75 km in width and from at least 10 km to more...
Geology, coal resources, and chemical analyses of coal from the Fruitland Formation, Kimbeto EMRIA study site, San Juan County, New Mexico
Gary B. Schneider, Rick T. Hildebrand, Ronald H. Affolter
1979, Open-File Report 79-1090
The Kimbeto EMRIA study site, an area of about 20 square miles (52 km2), is located on the south margin of the San Juan Basin on the gently northward-dipping strata of the Upper Cretaceous Fruitland Formation and the Kirtland Shale. The coal beds are mainly in the lower 150 feet...
Water-resources data index for Osceola National Forest, Florida
Paul R. Seaber, Robert W. Hull
1979, Open-File Report 79-984
The U.S. Geological Survey conducted an intensive investigation from December 1975 to December 1977 of the geohydrology of Osceola National Forest. The primary purpose of that investigation was to provide the geohydrological understanding needed to predict the impact of potential phosphate industry operations in the forest on the natural hydrologic...
Decollement in the southern Allegheny Plateau of Pennsylvania
Howard A. Pohn, Terri L. Purdy
1979, Open-File Report 79-1321
Recent field investigations in the Allegheny Plateau north of Williamsport, Pennsylvania have shown the presence of both southward dipping, low-angle thrust faults translated to the north and northward dipping back or antithectic thrusts translated to the south at the leading (north) edge of Barclay syncline. The presence of these thrusts,...
Discharge characteristics of triangular-notch thin-plate weirs
John Shen
1979, Open-File Report 79-1476
The triangular-notch, thin-plate weir is a convenient, inexpensive, and relatively precise flow-measuring instrument. It is frequently used to measure the flow of water in laboratories and in small, natural streams. The purpose of this report is to present a comprehensive analysis of the discharge characteristics of triangular-notch weirs. Previously-published data...
Upper Cretaceous tectonic activity on lineaments in western South Dakota
George W. Shurr
1979, Open-File Report 79-1374
Lineaments mapped on satellite images in western South Dakota define a geometry of basement blocks, and paleotectonic activity on these lineament-bound blocks is recorded in sedimentary rocks. Mapping on seven Landsat images in an area of about 100,000 km2 reveals that lineaments are best developed along azimuths of N. 60°...
Petroleum source potential of rocks dredged from the continental slope in the eastern Gulf of Alaska
George Plafker, George Edwin Claypool
1979, Open-File Report 79-295
A bedrock dredging program by the R/V Sea Sounder in 1977 and 1978 along the continental slope in the eastern Gulf of Alaska revealed a previously unknown Eocene sedimentary sequence that includes argillaceous rocks with favorable petroleum source rock characteristics. Seven of 36 dredge hauls that sampled outcrop contain argillaceous...
Compilation of strong-motion records from the August 6, 1979 Coyote Lake earthquake
R. L. Porcella, R.B. Matthiesen, R.D. McJunkin, J.T. Ragsdale
1979, Open-File Report 79-385
This report represents a joint effort by the OSMS, CDMG and the U.S. Geological Survey (USGS). The report summarizes all strong-motion accelerograph records recovered from the August 6, 1979 Coyote Lake earthquake. The majority of accelerograms were recorded at stations operated by the OSMS-CDMG and USGS; the latter organization operates...
Magnetometer traverse on Plum Island near Newburyport, Massachusetts
Robert W. Simpson, Wallace A. Bothner
1979, Open-File Report 79-435
Several large faults of regional tectonic significance circle around Boston and disappear offshore at Plum Island south of Newburyport, Massachusetts (Castle and others, 1976; Barosh and others, 1977). The traces of these faults are, in places, well defined by aeromagnetic anomalies (Harwood and Zietz, 1977), The purpose of this traverse...
Investigation of the Hosgri fault, offshore southern California, Point Sal to Point Conception
C. M. Payne, O. E. Swanson, B. A. Schell
1979, Open-File Report 79-1199
A high-resolution seismic reflection survey of the inner continental shelf between Point Sal and Point Conception has revealed faults that displace post-Wisconsin strata (less than 17,000-20,000 years). These faults are the Hosgri fault, the Offshore Lompoc fault, and smaller unnamed faults. Faults trending offshore from the adjacent shoreline such as...
A continuous water sampling and multi-parameter measurement system for estuaries
Laurence E. Schemel, Lee A. Dedini
1979, Open-File Report 79-273
Salinity, temperature, light transmissivity, oxygen saturation, turbidity, pH, pCO2, and chlorophyll a fluorescence of a pumped water sample are continuously measured with a system designed primarily for estuarine studies. Near-surface water from a depth of 2 m is sampled continuously while the vessel is underway or water at depths to...
Availability of single channel seismic refraction profiles collected over U.S. Atlantic continental slope and rise north of Cape Hatteras - USGS cruises FAY 20 and FAY 21 - August/September 1976
Kim D. Klitgord
1979, Open-File Report 79-578
A series of single channel seismic reflection profiles were collected by the U.S. Geological Survey aboard the R.V. FAY from August 10, 1976 through September 7, 1976 during cruises FAY 20 and FAY 21. The chief scientist was, Dr. Kim D. Klitgord, U.S. Geological Survey, Woods Hole, MA 02543. The...
Depth determination of Colvocoresses Reef, Indian Ocean (EC-68-Landsat)
Alden P. Colvocoresses
1979, Open-File Report 79-726
The depth to the subject reef has been estimated at a nominal 10 n by three independent analyses based on Landsat and (in two cases) comparisons.: to measured depths of submerged features in the same area. Fathometer readings made in 1979 confirm the 1O-m reading....
