Geomagnetic reversal boundaries of the last 3 Myr: what is their real age?

  • Rivera, Tiffany (Project participant)

    Project: Research

    Project Details

    Description

    Our aim is to intercalibrate high-precision 40Ar/39Ar ages with refined astronomically derived values for the youngest part of the geological record (the last 3 Myr). Focus will be in particular on dating geomagnetic reversal boundaries by both methods in view of existing inconsistencies with previously proposed intercalibrations. The outcome of this project will directly be applied to determine phase relations between astronomical forcing and climate response and constrain the tuning of pre-Neogene successions.
