Argon data for HD-B1 intercalibration

Published by U.S. Geological Survey | Department of the Interior | Metadata Last Checked: January 27, 2026 | Last Modified: 2022-04-28T00:00:00Z
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.
