Reconnaissance geology north of the Hoholitna River, Taylor Mountains D-1 1:63,360-scale quadrangle, southwestern Alaska: A section in Geological studies in Alaska by the U.S. Geological Survey, 1999 Reconnaissance geology north of the Hoholitna River, Taylor Mountains D-1 1:63,360-scale quadrangle, southwestern Alaska: A section in Geological studies in Alaska by the U.S. Geological Survey, 1999
The lower Paleozoic (Silurian and Ordovician) carbonate stratal succession is divided into six unnamed stratigraphic units in the northern part of the Taylor Mountains D-1 1:63,360-scale quadrangle of southwestern Alaska. Several of these units have previously been recognized in the McGrath and Medfra quadrangles to the northeast in strata of the Nixon Fork subterrane of the Farewell...

Geochemistry of selected mercury mine-tailings in the Parkfield Mercury District, California Geochemistry of selected mercury mine-tailings in the Parkfield Mercury District, California
The Parkfield mercury district is located in the southern part of the California Coast Range mercury mineral belt and contains three silica-carbonate-type mercury deposits that have had significant mercury production. Mercury was first produced in the district in 1873, but the main period of production occurred from 1915-1922. Total production from the district is about 5,000 flasks of...

Digital data for construction material sources reported by the Arizona Department of Transportation in 1977 for Maricopa County, Arizona Digital data for construction material sources reported by the Arizona Department of Transportation in 1977 for Maricopa County, Arizona
Material inventories for prospective sources of material for use in building roads and associated structures were prepared by Arizona for several counties including Maricopa County. The inventories provide information about pit locations, materials classification and type, and measures of some characteristics used to determine suitability for aggregate. The digital data given in this...

Preliminary potential-field constraints on the geometry of the San Fernando basin, Southern California Preliminary potential-field constraints on the geometry of the San Fernando basin, Southern California
Gravity and magnetic data provide new insights on the structural underpinnings of the San Fernando Basin region, which may be important to ground motion models. Gravity data indicate that a deep basin (>5 km) underlies the northern part of the San Fernando Valley; this deep basin is required to explain the lowest gravity values over the Mission Hills thrust fault. Gravity modeling...

Locations and ages of middle Tertiary volcanic centers in coastal California Locations and ages of middle Tertiary volcanic centers in coastal California
This report includes a map and three tables that summarize available information on the locations and ages of late Oligocene to middle Miocene volcanic centers in coastal California. This information, in turn, provides supporting documentation for a planned formal publication by D.S. Wilson, P.A. McCrory, and R.G. Stanley on the implications of volcanism in coastal California for the...

Publications of the Western Earth Surface Processes Team, 1999 Publications of the Western Earth Surface Processes Team, 1999
The Western Earth Surfaces Processes Team (WESPT) of the U.S. Geological Survey, Geologic Division (USGS, GD), conducts geologic mapping and related topical earth- science studies in the western United States. This work is focused on areas where modern geologic maps and associated earth-science data are needed to address key societal and environmental issues such as ground-water quality...
