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.

Airborne electromagnetic, magnetic, and radiometric data collected in 2017 over 1,984 line-kilometers in this area. Data include inverted resistivity and IP models as well. Data are provided in CSV format.

Inorganic chemical analysis of surface- and groundwater and springs in this area to understand natural versus anthropogenic inputs from mineralized and hydrothermally altered areas. Data are provided in Esri file geodatabase, CSV, and shapefile formats.

Data from a helicopter magnetic survey in this area to understand the nature of aquifers, the potential for geothermal energy resources, the likelihood of seismic hazards, and the geology of the northern Rio Grande rift. Data are provided in GXF grid and CSV formats.

Full raw argon isotopic data for samples presented in a geologic map of the area. Data are provided in CSV format.

Chemical data from stream water, groundwater, and soil samples collected in 2019 and 2020 in this area. Data from a tracer study is included as tool for understanding sources and loading rates of metals affecting stream water quality in a watershed affected by legacy mining and natural sulfide-weathering. Data are provided in CSV format.
