Paleointensity Determination Using the Thellier Technique

Journal of geomagnetism and geoelectricity, 1986
The Thellier technique is discussed, specifically in respect of small (3×3mm) samples measured using a cryogenic magnetometer. It is concluded that as long as stringent criteria are imposed the technique gives reliable results. Agreement with the Shaw technique is noted, as also with observatory-based values.

Holocene Paleointensity of the Island of Hawai `i From Glassy Volcanics

Geochemistry, Geophysics, Geosystems, 2018
This study presents new high‐quality paleointensity records and 14C radiocarbon age determinations from the Island of Hawai `i during the Holocene. Previous studies on Hawai `i use experimental methods and statistical selection criteria that may produce ...

Dansgaard‐Oeschger Events Recorded in Low‐Latitude Marine Sediments and Teleconnection With High‐Latitude Climate Variations

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 ...

The Magnetic Mineralogy of Carbonaceous Chondrites: A Microscopy and Machine Learning Study of Meteorite WIS 91600

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 ...
