Existing and new gravity station data and magnetometer measurements used to infer geologic structure of this area

Magnetotelluric (MT) sounding data collected in 2003 along a north-south profile in this area to learn whether major mining districts in the Northern Nevada Gold Province are underlain by rocks of the Archean Wyoming craton, which are known to contain orogenic gold deposits, or by accreted rocks of the Paleoproterozoic Mojave province.

Physical property measurements rocks from this area, including station identifier, geographic coordinates, rock type, density, magnetic susceptibility, remanent magnetization, declination, and inclination where available. Data are provided in CSV format. Sample locations are provided in shapefile format.

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.

Descriptions of the only U.S. sites-including mining districts, mineral occurrences, and mine features-that have reported production and (or) resources of indium (In). Data are provided in CSV, Esri file geodatabase, and shapefile formats.

Nevada is one of the Earth's premier gold producing regions, accounting for approximately 64 percent of the U.S and nine percent of the world total. The impact of these mines on nearby local economies and on our national balance of payments is profound, a
