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.

This data release consists of point data digitized from structural geologic orientation symbols consisting of mostly foliations and lineations from twenty-three geologic maps published between 1964 and 2009, primarily 7.5-minute, 1:24,000 scale quadrangles. Data are provided in Esri file geodatabase, shapefile, CSV, and Microsoft Excel formats.
