Published by U.S. Geological Survey | Department of the Interior | Catalog Last Checked: May 05, 2026 at 09:33 PM | Dataset Last Updated: April 28, 2022 at 12:00 AM
This data release includes 40Ar/39Ar intercalibration data from the U.S. Geological Survey for neutron fluence monitors HD-B1 (Heidelberg biotite) and FCs (Fish Canyon sanidine). Potassium-bearing mineral grains were analyzed by argon geochronology at the U.S. Geological Survey Argon Geochronology Laboratory in Denver, Colorado. These data provide intercalibration information between the two fluence monitors.
