An initial case study to deconvolve natural remanent magnetization of a continuous paleomagnetic sample using the software UDECON

Earth, Planets and Space, 2018
Previous studies have compiled relative paleointensity data for the last 2–3 Ma from individual paleomagnetic records obtained from marine sediment cores. These records have mostly been obtained by pass-through measurements, which are known to smooth and

Characteristics of Natural Remanence Records in Fine‐Grained Particles Returned From Asteroid Ryugu

Journal of Geophysical Research: Planets, Volume 131, Issue 2, February 2026.
Abstract Particles collected from the asteroid Ryugu by the Hayabusa2 spacecraft offer a unique opportunity to investigate the magnetic record of the primitive solar system, as any terrestrial magnetic contamination is minimal and can be accounted for.

Decadal‐Scale In Situ Scanning of a Stalagmite From Southwest China Reveals Blake Geomagnetic Excursion Structure

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract We present a decadal‐scale paleomagnetic analysis of a stalagmite collected from Shuixi Cave, southwest China, spanning 89−123 ka. Our findings include: (a) Magnetite is the dominant magnetic mineral, and paleomagnetic directions can be obtained via demagnetization; (b) Magnetic scanning at 0.1‐mm resolution captures key magnetic features ...

Variable remanence acquisition efficiency in sediments containing biogenic and detrital magnetites: Implications for relative paleointensity signal recording [PDF]

, 2014
Widespread geological preservation of biogenic magnetite makes it important to assess how such particles contribute to sedimentary paleomagnetic signals.

Effects of Aging on Magnetic Mineralogy of Natural Volcanic Glass: Implications for Geomagnetic Paleointensity Recorders

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 1, January 2026.
Abstract Natural volcanic glasses are well represented in the geologic record, and typically contain near‐ideal single‐domain particles required for standard Thellier‐type absolute paleointensity experiments. Young (<∼50–100 ka) glasses have been demonstrated to reliably record Earth's magnetic field.

Linearity of natural versus laboratory-imparted remanence demagnetization diagram and reliability of relative paleointensity estimation

Earth, Planets and Space
Information on geomagnetic field intensity in the past is essential for understanding the behavior and mechanism of the geodynamo. A fundamental unresolved problem of relative paleointensity (RPI) estimations from marine sediments is that changes in the ...

A first‐order correction to minimize environmental influence in sedimentary records of relative paleointensity of the geomagnetic field [PDF]

Geochemistry, Geophysics, Geosystems, 2006
We propose a simple method to minimize the residual environmental influence which may exist in paleointensity records obtained from sediments. It consists of adding, or subtracting, a fraction of the normalizer (κ, ARM, or IRM) to the normalized intensity record, so that the corrected record exhibits fluctuations uncorrelated with those of the ...
