Our fission-track age (13.98±0.58Ma) agrees with a recent 40Ar/39Ar age, 14.34±0.04Ma, based on several determinations on Moldavites from different sediments, including the Jankov deposit. This result indicates that the U and Th thin film neutron dosimetry represents a reliable alternative for an absolute approach in fission-track dating. © 2005 Elsevier Ltd.
