Seismicity map of the state of Utah Seismicity map of the state of Utah
This map is one of a series of seismicity maps produced by the U. S. Geological Survey that show earthquake data of individual states or groups of states at the scale of 1:1,000,000. This map shows only those earthquakes with epicenters located within the boundaries of Utah, even though earthquakes in nearby states or countries may have been felt or may have caused damage in Utah. The...
Stratigraphic framework of coal beds underlying the northeastern part of the Fort Peck Indian Reservation, Montana Stratigraphic framework of coal beds underlying the northeastern part of the Fort Peck Indian Reservation, Montana
The area of investigation is located in the northeast part of the Fort Peck Indian Reservation (fig. 1) on the western flank of the Williston Basin. It covers about 450 square miles and is made up of parts of Daniels, Sheridan, and Roosevelt counties. Exploratory drilling for coal and logging of seismograph drill holes in 1978-1981 were done with the support of the Branch of Indian...
Structure contour map of the tops of the Kreyenhagen Formation and Cretaceous strata in the Coalinga area, Fresno and Kings counties, California Structure contour map of the tops of the Kreyenhagen Formation and Cretaceous strata in the Coalinga area, Fresno and Kings counties, California
This structure contour map, originally compiled during a study of the 1983 Coalinga earthquakes, shows the general structural configuration of the upper several kilometers of section in the Coalinga area. It was compiled by using electric well-log data available through April 1982 (Ammann Map Services, 1978; Petroleum Information Corporation, 1982; California Division of Oil and Gas...
Summary geochemical maps for samples of rock, stream sediment, and nonmagnetic heavy-mineral concentrate, Cypress Roadless Area, Kern County, California Summary geochemical maps for samples of rock, stream sediment, and nonmagnetic heavy-mineral concentrate, Cypress Roadless Area, Kern County, California
The Cypress Roadless Area comprises approximately 3 square miles (1,949 acres) of Sequoia National Forest, Kern County, California. The area is at the southern end of the Sierra Nevada, approximately 30 miles east-northeast of Bakersfield, and 2.5 miles and 3.5 miles south-southeast of the communities of Bodfish and Lake Isabella, respectively (index map). Geochemical sampling was...
Summary geochemical maps for samples of rock, stream sediment, and nonmagnetic heavy-mineral concentrate, east part of the Raymond Peak Roadless Area, Alpine County, California Summary geochemical maps for samples of rock, stream sediment, and nonmagnetic heavy-mineral concentrate, east part of the Raymond Peak Roadless Area, Alpine County, California
The Raymond peak Roadless Area consists of two separate units. The west part (5985), about 12 miles southwest of Markleeville in Stanislaus National Forest, has been studied separately as part of the Mokelumne Wilderness and vicinity (McKee and others, 1982). The east part (4985) is discussed here.
Summary geochemical maps for samples of rock, stream sediment, and nonmagnetic heavy-mineral concentrate, Pyramid Roadless Area, El Dorado County, California Summary geochemical maps for samples of rock, stream sediment, and nonmagnetic heavy-mineral concentrate, Pyramid Roadless Area, El Dorado County, California
The Wilderness Act (Public Law 88-577, September 3, 1964) and related acts require the U.S. Geological Survey and the U.S. Bureau of Mines to survey certain areas on Federal lands to determine their mineral resource potential. Results must be made available to the public and be submitted to the President and the Congress. This report presents the results of a geochemical survey of the...
