Spatial digital database for the tectonic map of southeast Arizona Spatial digital database for the tectonic map of southeast Arizona

A spatial database was created for Drewes' (1980) tectonic map of southeast Arizona: this database supercedes Drewes and others (2001, ver. 1.0). Staff and a contractor at the U.S. Geological Survey in Tucson, Arizona completed an interim digital geologic map database for the east part of the map in 2001, made revisions to the previously released digital data for the west part of the map...

Stratigraphy of the Upper Cretaceous Mancos Shale (upper part) and Mesaverde Group in the southern part of the Uinta and Piceance basins, Utah and Colorado Stratigraphy of the Upper Cretaceous Mancos Shale (upper part) and Mesaverde Group in the southern part of the Uinta and Piceance basins, Utah and Colorado

Cross section A–A' was constructed in support of the oil and gas assessments of the Mesaverde and Mancos/Mowry Total Petroleum Systems in the Uinta and Piceance Basins of Utah and Colorado (fig. 1) (U.S. Geological Survey Uinta-Piceance Province Assessment Team, in press). This citation is referred to henceforth as simply “USGS, in press.” The Mesaverde Total Petroleum System contains...

Sun-Illuminated Sea Floor Topography of Quadrangle 1 in the Great South Channel, Western Georges Bank Sun-Illuminated Sea Floor Topography of Quadrangle 1 in the Great South Channel, Western Georges Bank

The Great South Channel separates the western part of Georges Bank from Nantucket Shoals and is a major conduit for the exchange of water between the Gulf of Maine to the north and the Atlantic Ocean to the south. Water depths range mostly between 65 and 80 m in the region. A minimum depth of 45 m occurs in the east-central part of the mapped area, and a maximum depth of 100 m occurs in...

Surficial geologic map of the Bettles quadrangle, Alaska Surficial geologic map of the Bettles quadrangle, Alaska

This dataset represents surficial geologic mapping of the Bettles quadrangle, Alaska. It is used to create the mapsheet in MF-2409, which shows surficial deposits of the 1:250,000 scale Bettles quadrangle in north central Alaska.

Surficial Geologic Map of the Hughes Quadrangle, Alaska Surficial Geologic Map of the Hughes Quadrangle, Alaska

This dataset represents surficial geologic mapping of the Hughes quadrangle, Alaska. It is used to create the mapsheet in MF-2408, which shows surficial deposits of the 1:250,000 scale Hughes quadrangle in north central Alaska.

Surficial Geologic Map of The Loop and Druid Arch Quadrangles, Canyonlands National Park, Utah Surficial Geologic Map of The Loop and Druid Arch Quadrangles, Canyonlands National Park, Utah

This geologic map is a product of a cooperative project between the U.S. Geological Survey and the U.S. National Park Service to provide geologic information about this part of Canyonlands National Park, Utah. This digital map database contains bedrock data from previously published data that has been modified by the author. New mapping of the surficial deposits

Arsenic in stream sediments of northern Alabama Arsenic in stream sediments of northern Alabama

OVERVIEW OF ARSENIC IN STREAM SEDIMENTS The overall range of arsenic in the NURE stream sediments was from 0.3 to 44 mg/kg sediment (ppm) As in the sample data set. The mean value was 4.3 ppm with a standard deviation of 4.1 ppm. For comparison, the crustal abundance of arsenic is 1.8 ppm (Taylor, 1964). Shale is higher, with average values of 15 ppm. Coal samples from the entire USGS...
