Chemical composition of samples collected from waste rock dumps and other mining-related features at selected phosphate mines in southeastern Idaho, western Wyoming, and northern Utah Chemical composition of samples collected from waste rock dumps and other mining-related features at selected phosphate mines in southeastern Idaho, western Wyoming, and northern Utah
This report provides chemical analyses for 31 samples collected from various phosphate mine sites in southeastern Idaho (25), northern Utah (2), and western Wyoming (4). The sampling effort was undertaken as a reconnaissance and does not constitute a characterization of mine wastes. Twenty-five samples were collected from waste rock dumps, 2 from stockpiles, and 1 each from slag...

Reconnaissance geologic map of the Dixonville 7.5' quadrangle, Oregon Reconnaissance geologic map of the Dixonville 7.5' quadrangle, Oregon
The Dixonville 7.5 minute quadrangle is situated near the edge of two major geologic and tectonic provinces the northernmost Klamath Mountains and the southeastern part of the Oregon Coast Ranges (Figure 1). Rocks of the Klamath Mountains province that lie within the study area include ultramafic, mafic, intermediate and siliceous igneous types (Diller, 1898, Ramp, 1972, Ryberg, 1984)...

Shaded-relief and color shaded-relief maps of the Willamette Valley, Oregon Shaded-relief and color shaded-relief maps of the Willamette Valley, Oregon
This Open-File Report is released as a digital map database. It includes PostScript plot files that contain images of the map sheets; the images also contain a brief explanation describing the geology and physiography of the study area. The digital map database is a compilation of newly published 10-m digital-elevation-model (DEM) data for western Oregon and represents the physiography...

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...
