MAS/MILS Arc/Info point coverage for the western U.S. (excluding Hawaii) MAS/MILS Arc/Info point coverage for the western U.S. (excluding Hawaii)
The U.S. Geological Survey has two international and one regional digital database that contains information on mineral properties. This report describes the conversion of selected data from one of the international databases - MAS/MILS (Mineral Availability System/Mineral Industry Location System) - into a spatial data product. The MAS/MILS database, obtained from the U.S. Bureau of...

Oreshoot zoning in the Carlin-type Betze orebody, Goldstrike Mine, Eureka County, Nevada Oreshoot zoning in the Carlin-type Betze orebody, Goldstrike Mine, Eureka County, Nevada
Field and laboratory investigations of the giant Betze gold orebody, the largest Carlin-type deposit known, in the north-central Carlin trend, Nevada document that the orebody is composed of individual high-grade oreshoots that contain different geologic, mineralogic, and textural characteristics. The orebody is typical of many structurally controlled Carlin-type deposits, and is hosted...

Geology of Palo Alto 30 x 60 minute quadrangle, California: A digital database Geology of Palo Alto 30 x 60 minute quadrangle, California: A digital database
This map database represents the integration of previously published and unpublished maps by several workers (see Sources of Data index map on Sheet 2 and the corresponding table below) and new geologic mapping and field checking by the authors with the previously published geologic map of San Mateo County (Brabb and Pampeyan, 1983) and Santa Cruz County (Brabb, 1989, Brabb and others...

Corrections to "Estimating earthquake location and magnitude from seismic intensity data" Corrections to "Estimating earthquake location and magnitude from seismic intensity data"
The confidence parameters in Table 5 and Figures 7 -12 in Bakun and Wentworth (1997) were calculated using the site corrections for MI(4) rather than Bakun and Wentworth's (1997) preferred relation MI(3). The conclusions of Bakun and Wentworth (1997) are not changed by these corrections. The corrected Table 5 and Figures are in this report and at http://quake.wr.usgs.gov/~bakun/.

Rotational and accretionary evolution of the Klamath Mountains, California and Oregon, from Devonian to present time Rotational and accretionary evolution of the Klamath Mountains, California and Oregon, from Devonian to present time
The purpose of this report is to show graphically how the Klamath Mountains grew from a relatively small nucleus in Early Devonian time to its present size while rotating clockwise approximately 110°. This growth occurred by the addition of large tectonic slices of oceanic lithosphere, volcanic arcs, and melange during a sequence of accretionary episodes. The Klamath Mountains province...

Alaska resource data file: McCarthy quadrangle Alaska resource data file: McCarthy quadrangle
Descriptions of the mineral occurrences shown on the accompanying figure follow. See U.S. Geological Survey (1996) for a description of the information content of each field in the records. The data presented here are maintained as part of a statewide database on mines, prospects and mineral occurrences throughout Alaska.
