Post-depositional remanent magnetization lock-in for marine sediments deduced from 10 Be and paleomagnetic records through the Matuyama-Brunhes boundary

Suganuma, Yusuke; Okuno, Jun'ichi; Heslop, David; Roberts, Andrew; Yamazaki, Toshitsugu; Yokoyama, Yusuke


Geomagnetic field intensity records from marine sediments have contributed to improved understanding of variations in the Earth's magnetic field, and have helped to establish age models for marine sediments. However, lock-in of the geomagnetic signal below the sediment-water interface in marine sediments through acquisition of a post-depositional remanent magnetization (PDRM) adds uncertainty to synchronization of marine sedimentary records. Although quantitative models enable assessment of...[Show more]
