Maps and data showing the geographic distribution of surficial minerals likely produced by hydrothermal alteration, which may indicate areas permissive of gold and copper mineral deposits.

Maps and data showing the geographic distribution of surficial minerals likely produced by hydrothermal alteration, which may indicate areas permissive of gold and copper mineral deposits.

Spatial databases for map units, strike and dip, geologic contacts, faults, dikes, in addition to a topographic base map are provided in an Esri file geodatabase. The geologic mapsheet is also provided as a PDF.

Surficial geochemical methods used to identify subsurface mineral deposits covered by alluvium. Can a geophysical anomaly, interpreted as a buried granite pluton, be discerned from the geochemical characteristics of overlying Quaternary sediments?

Geologic map GIS which represents the original content of the published geologic map and which can be queried in many ways to produce a variety of geologic maps and derivative products.

Measurements of in-situ magnetic properties of several map units to determined whether or not mapped lithologies were responsible for aeromagnetic anomalies observed in a previous high-resolution survey (data of Sweeney, 2000).

Grids and flight-line data for the surveys of this area

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.

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

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.

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

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.

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.
