    • Frequency domain electromagnetic induction (FDEM) data collected around mine-impacted streams near Silverton, Colorado in September 2019 and 2021 (ver. 2.0, May 2022)

    Metadata Updated: July 6, 2024

    This child item contains frequency domain electromagnetic induction (FDEM) data collected along and around Cement Creek California Gulch, and the Animas River near Silverton, Colorado in support of other data collected at the site. The FDEM tool generates an EM field and measures eddy currents generated by conductive and/or magnetic materials in the subsurface in response to the applied field. A Geophex GEM-2 instrument with GPS was used with frequencies ranging from 450 Hz to 47970 Hz. Additional details are contained in the ‘readme.txt’ files within each zip data directory.
