Test drilling at Soldier Creek, Rosebud Indian Reservation, Todd County, South Dakota
D. G. Adolphson
1975, Open-File Report 75-355
Thirty-six test holes were augered by the U.S. Geological Survey in the vicinity of Sol,,r Creek, Rosebud Indian Reservation, Todd County, South Dakota. Wells prcducing more than S gallons per minute (0.32 litre per second) from the Tertiary deposits are rare. However, as much as 20 feet (6.1 metres) of...
A Study of earthquake losses in the Puget Sound, Washington, area
Water Resources Division, U.S. Geological Survey
1975, Open-File Report 75-375
The Puget Sound Basin has a history of frequent seismic activity, including two recent damaging events. The greatest extent of urban development and the most densely populated area generally correspond to the area where the greatest energy release has been experienced. For this study two earthquakes have been simulated, each...
A review of recently active faults in Taiwan
Manuel G. Bonilla
1975, Open-File Report 75-41
Six faults associated with five large earthquakes produced surface displacements ranging from 1 to 3 m in the period 1906 through 1951. Four of the ruptures occurred in the western coastal plain and foothills, and two occurred in the Longitudinal Valley of eastern Taiwan. Maps are included showing the locations...
Interim report on petroleum resource potential and geologic hazards in the outer continental shelf of the Gulf of Alaska Tertiary province
George Plafker, Terry R. Bruns, Robert A. Page
1975, Open-File Report 75-592
The potential for discovering large accumulations of petroleum on the Outer Continental Shelf of the Gulf of Alaska Tertiary Province cannot be evaluated with much confidence at present because of the inadequacies of the available offshore geological and geophysical data. The 22 deep test wells that have been drilled since...
Influence of caustic and water leaching on analcime-bearing and analcime-free pyrolyzed oil shale from the Green River Formation, Piceance Creek Basin, Colorado
George A. Desborough, Wayne Mountjoy, Irving C. Frost
1975, Open-File Report 75-156
The influence of oil-shale mineral constitution on the amounts of Na2O, Al2O3, and SiO2 extractable from pyrolyzed oil shale using hot water and hot caustic solvents has been examined. Samples of oil shale from two drill cores and one composite sample from the Colony mine were split and studied by...
Tectonic framework of petroliferous rocks in Alaska
Arthur Grantz, C.E. Kirschner
1975, Open-File Report 75-149
Alaska, comprising 3.6 X 106 sq km (about 28 percent) of the land, shelf, and upper continental slope of the United States, has been estimated by the U.S. Geological Survey (1974) to contain about 25 percent of the Nation's petroleum resources. Some 11 billion barrels of petroleum liquids and 31...
