Reitman, J., Rodriguez, B.D., and Brown, P.J., 2019, Audiomagnetotelluric sounding data in the Silverton Caldera complex, Colorado, 2018: U.S. Geological Survey data release,


This dataset includes audiomagnetotelluric (AMT) sounding data collected in July 2018 in the Silverton Caldera complex, Colorado, in the Southern Rocky Mountain Volcanic Field, by the U.S. Geological Survey (USGS). Along with geologic mapping, airborne magnetics, airborne electromagnetics, and magnetotellurics, the USGS collected AMT data at 24 sites along four profiles ranging from 3 to 6 kilometers in length across the north-western structural margin of the Silverton caldera in Mineral Basin (MB01-MB05), across the south-eastern margin of the caldera along Cunningham Creek (CC01-CC05), within the caldera in Eureka Graben (EG01-EG05), and within the caldera along upper Cement Creek near the Gold King mine (GK01-GK09).

The purpose of this data release is to provide audiomagnetotelluric (AMT) station locations and data to the public. The purpose of the survey is to help to characterize subsurface rock properties important for understanding surface water and groundwater quality issues, and also to improve knowledge of deep geologic structures that may have been conduits for hydrothermal fluids that formed mineral deposits. The study also has general applications to mineral resource assessments in other areas of the world, and to identifying possible groundwater flow paths and associated geochemistry important in abandoned mine lands cleanup.
