Relative palaeointensity stack of IODP Site 379-U1533

DOI

Relative palaeointensity analyses for IODP Site 379-U1533, completed in 2020-2022 at the University of Southampton. Three methods shown: natural remanent magnetisation (NRM) normalised by anhysteretic remanent magnetisation (ARM) (NRM/ARM) for the alternating field (AF) demagnetisation range 20-55 mT (preferred method for IODP Site 379-U1533 and used in further interpretations); NRM (at 20 mT AF demagnetisation) normalised by magnetic susceptibility (MS) (NRM/MS); and NRM normalised by isothermal remanent magnetisation (IRM) for the alternating field (AF) demagnetisation range 20-60 mT (NRM/IRM). All three methods show strong coherent signal suggesting an NRM signal largely consisting of a geomagnetic field component. R-values shown for analyses completed using UPmag slope method (Xuan and Channell, 2009 doi:10.1029/2009GC002584). Measurements cover the Plio-/Pleistocene period.
