Tabular and geospatial data digitized from a U.S. Bureau of Mines that presented results of a mineral resource potential survey in this area. Georeferenced scanned plates are provided in JPEG format, other data are provided in Esri file geodatabase, CSV, and shapefile formats.

Data from 102 magnetotelluric (MT) stations collected from 2012 through 2014 in this area to improve regional conductivity models of the western United States.

Based on detailed information on the location of the Tertiary intrusions and mineral deposits, and on the control provided by the Proterozoic structures, all superimposed using GIS, a new outline of the Colorado Mineral Belt is proposed. Older representations are included for comparison. Data are provided in shapefile format.

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.

Whole-rock major and trace element analyses of 51 samples of breccias, veins and thin dikes, and a variety of carbonatite, felsic, mafic, and ultramafic intrusions across the area to understand the mineralization of rare earth elements and thorium in this area. Data are provided in Microsoft Excel and CSV formats.
