Reconnaissance snow surveys of the National Petroleum Reserve in Alaska, April 1977 and April-May 1978
Charles E. Sloan, Dennis Trabant, William Glude
1979, Open-File Report 79-1342
Reconnaissance snow surveys of the NPRA (National Petroleum Reserve in Alaska) were made in April 1977 and April-May 1978 to ascertain general snow characteristics and distribution patterns. Thirty-nine sites in 1977 and forty-one sites in 1978 were sampled to determine snow depth, density, structure, and snow-soil interface temperature. In addition,...
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...
Palladium, platinum, and rhodium concentrations in mafic and ultramafic rocks from the Kizildag and Guleman areas, Turkey, and the Faryab and Esfandagheh-Abdasht areas, Iran
Norman J. Page, Tandogan Engin, Joseph Haffty
1979, Open-File Report 79-840
The Kizildag and Guleman areas, Turkey, and the Faryab and Esfandagheh-Abdasht areas, Iran, have produced chromite from ophiolite complexes consisting of harzburgite tectonite, dunite tectonite containing chromitite, pyroxenite, wehrlite, and gabbro. Forty-six samples from these complexes were analyzed in order to investigate the possibility of platinum-group metals being present that...
The subsurface geology of the Florida-Hatteras shelf, slope, and inner Blake Plateau
Charles K. Paull, William P. Dillon
1979, Open-File Report 79-448
The structure and stratigraphy of the Florida-Hatteras Slope and inner Blake Plateau was studied by means of 4,780 km of single-channel air gun seismic reflection profiles. Control for the seismic stratigraphy is provided by correlating reflecting units and paleontologically dated stratigraphic units identified in offshore wells and dredge hauls. Many...
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...
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...
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,...
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...
