Two Records of Relative Paleointensity for the Past 4 Myr [PDF]
Frontiers in Earth Science, 2020 We performed new high-resolution magnetic measurements of sedimentary cores from the east northern Pacific ODP Site 1021 and the East equatorial Pacific ODP Site 851.

Wavelet-based verification of a relative paleointensity record from the North Pacific [PDF]
Earth, Planets and Space, 2019 We present a relative paleointensity (RPI) record for the last ~ 1.1 Myr estimated from a sediment core in the central North Pacific, with quality verification using wavelet analysis.

The importance of clays in speleothem magnetic remanence acquisition [PDF]
Scientific ReportsSpeleothems are promising recorders of paleosecular variation of the Earth’s magnetic field, but ambiguities remain about the physical processes active during remanence acquisition.

Millennial paleoclimate variations on the Central Tibetan Plateau during MIS4-MIS2 inferred from a sediment core based RPI chronology [PDF]
Scientific ReportsLakes on the Tibetan Plateau, highly sensitive to environmental changes, play a key role in paleoclimatic studies. However, dating limitations often constrain investigations to periods before the Last Glacial Maximum (LGM).

Magnetic mineralogy of the Baringo core (HSPDP-BTB13-1A, Kenya) shows astronomical forcing with implications for retrieving meaningful paleointensity [version 1; peer review: 2 approved] [PDF]
Open Research EuropeThis study evaluates the potential of the BTB13 sedimentary core from the Baringo Basin, Kenya, to contribute to relative paleointensity (RPI) records and improve geochronological correlations across Eastern Africa.

Speleothems as Magnetic Archives: Paleosecular Variation and a Relative Paleointensity Record From a Portuguese Speleothem [PDF]
Geochemistry, Geophysics, Geosystems, 2018 We provide a high‐resolution and complete paleomagnetic study from a middle‐Holocene (~4,100–3,300 years Before Common Era, BCE) dome‐shaped speleothem (SPAIV) from Algarve, Portugal.

A 2.14-Myr astronomically tuned record of relative geomagnetic paleointensity from the western Philippine Sea [PDF]
Journal of Geophysical Research, 2003 We present a 2.14‐Myr astronomically tuned relative geomagnetic paleointensity record from the western Philippine Sea. Pseudosingle‐domain titanomagnetite is the only magnetic mineral identified and variations in titanomagnetite concentration fall well within the accepted limits for relative paleointensity variations.

Rock‐magnetic artifacts on long‐term relative paleointensity variations in sediments
Geochemistry, Geophysics, Geosystems, 2013 Long‐term changes of geomagnetic field intensity, including possible dependence on lengths of polarity intervals, provide fundamentally important information for understanding the geodynamo. A positive correlation between paleointensity and polarity interval length was previously suggested from an Oligocene (ca. 23–34 Ma) relative paleointensity record
