Chemistry and geologic information for nearly 30,000 historic ore and ore-related rock samples from mineral deposits and mining districts in the United States. Data are provided in Microsoft Access and CSV formats.

Extensive core drilling has delineated a large, deep seated, structurally intact deposit here. Distribution of elements and minerals determined for this study provide a zoning model applicable to similar deposits and useful for resource exploration.

Chemistry and geologic information for historic ore and ore-related rock samples from mineral deposits in the United States and from archetypal deposits from 27 other countries. Data are provide in Microsoft Access, Microsoft Excel, and CSV formats.

Analyses of core and surface samples collected in and around this mineral deposit. Samples were collected and analyzed between 1980 and 2000. Data are provided in Microsoft Excel and CSV formats.

Audiomagnetotelluric (AMT) sounding data collected in 2008 in this area in support of assessments of concealed mineral resources.

Magnetotelluric sounding data collected in 2008 in this area to help USGS understand concealed mineral resources.

40Ar/39Ar data from samples in this area to provide age constraints on units in the relevant geologic mapping. Data are provided in CSV and shapefile formats.

Phytostabilization reduces the mobility of inorganic contaminants by establishing or enhancing plant growth. For small, remote, or abandoned mines, phytostabilization may reduce potential environmental hazards, provided plants can establish and grow. We grew a widespread perennial grass in mining wastes with and without soil and microbial amendments to determine whether we could improve plant establishment and growth. Data are provided in CSV format.
