Geomagnetic paleointensity dating of South China Sea sediments for the last 130 kyr
, 2009 Relative paleointensity records from the northern South China Sea, northwest Pacific Ocean were studied in two gravity piston cores. Continuous mineral magnetic and paleomagnetic measurements were made using discrete sediment samples.

Geochemistry, Geophysics, Geosystems, 2020 Gyro‐remanent magnetization (GRM) is a frequently occurring yet unwanted remanence contamination for certain samples during alternating field (AF) demagnetization of the natural remanent magnetization.

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.Abstract Dansgaard‐Oeschger (D‐O) events are millennial‐scale high‐latitude climate oscillations with abrupt climate transitions between stadial and interstadial conditions, which are well recorded in and outside of high northern latitudes. However, their signal propagation mechanisms from high to low latitudes are uncertain.

Paleosecular Variation Constraints on Geomagnetic Field Morphology at ca. 1100 Ma
Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.Abstract Paleosecular variation provides a statistical test of long‐term geomagnetic field morphology, but its behavior across Precambrian polarity regimes remains poorly constrained. We compile a virtual geomagnetic pole dispersion data set spanning 1130–1070 Ma and apply nonlinear Model G fitting to evaluate field structure across the interval ...

A Holocene Paleosecular Variation Record From the Northwestern Ross Sea, Antarctica
Geochemistry, Geophysics, GeosystemsWe present a mid‐to‐late Holocene record of relative paleosecular variation from the Ross Sea region of Antarctica. The 6,700‐year‐long record of inclination, declination, and relative paleointensity from a marine sediment core collected near Cape Adare ...

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 7, July 2026.Abstract A central challenge in the paleomagnetic study of meteorites is to characterize their diverse remanence carriers. Here, we develop a machine‐learning assisted workflow that combines multi‐scale (mm to nm) and multi‐dimensional (2D‐3D) microscopy to build a comprehensive picture of ferromagnetic mineralogy in the C2 ungrouped carbonaceous ...

A comparison of relative paleointensity records of the Matuyama Chron for the period 0.75–1.25 Ma
, 2006 International audienceA comparison of 15 records of relative geomagnetic paleointensity, spanning the time interval 0.75–1.25 Ma, has been performed after synchronizing the records at the paleointensity minima corresponding to geomagnetic reversals ...

Geochemistry, Geophysics, Geosystems, 2013 We obtain new 40Ar/39Ar ages for three lavas that record part of the Matuyama‐Brunhes geomagnetic field reversal process on Guadeloupe. These lavas record a reversed‐transitional‐reversed magnetostratigraphy and yield a weighted mean isochron age of 785 ...
