A multimethod paleointensity approach applied to the historical Xitle lava flows (Central Mexico): towards the accurate paleointensity determination

open access: yesEarth, Planets and Space, 2020
An inclusive rock-magnetic and absolute paleointensity survey of the ~ 2-ka-old Xitle volcano (southerly Basin of Mexico) was undertaken to assess the faithfulness of the paleomagnetic log carried by fresh, widely exposed and well-preserved lava flows ...

Recent eruptive history of Stromboli (Aeolian Islands, Italy) determined from high‐accuracy archeomagnetic dating [PDF]

open access: yesGeophysical Research Letters, 2004
The “large sample method” of archeomagnetic dating was applied to Stromboli. 127 samples (10 sites) yielded paleofield directions with 95% confidence intervals less than 2°. Coupled with a reference curve for secular variation in western Europe, these allow accurate dating of volcanic events.

Archeomagnetic intensity investigations of French medieval ceramic workshops: Contribution to regional field modeling and archeointensity-based dating

open access: yesPhysics of the Earth and Planetary Interiors, 2021
Seven new archeointensity data are obtained through the analysis of groups of pottery and kiln fragments from ceramic workshops unearthed in France, precisely dated from the High Middle Ages. The measurements are carried out using the Triaxe magnetometer, following a dedicated experimental protocol that takes into account the effects of anisotropy and ...

Recent Advances in Chinese Archeomagnetism

open access: yesFrontiers in Earth Science, 2017
The geomagnetic field is one of Earth's fundamental properties with a history of ~3.5 Gyr. The field, generated in Earth's core is a window to the deep interior of Earth and may have played a key role in evolution of life on our planet.

Effects of Global Geomagnetic Field Variations Over the Past 100,000 Years on Cosmogenic Radionuclide Production Rates in the Earth's Atmosphere

open access: yesJournal of Geophysical Research: Space Physics, Volume 128, Issue 8, August 2023., 2023
Abstract The production rates of cosmogenic radionuclides, such as 10Be, 14C, and 36Cl, in the Earth's atmosphere vary with the geomagnetic field and solar activity. For the first time, the production rates of several cosmogenic nuclides are estimated for the past 100 ka based on global, time‐dependent geomagnetic field models and a moderate solar ...

Changes in Non‐Dipolar Field Structure Over the Plio‐Pleistocene: New Paleointensity Results From Hawai'i Compared to Global Data Sets

open access: yesJournal of Geophysical Research: Solid Earth, Volume 128, Issue 6, June 2023., 2023
Abstract A foundational assumption in paleomagnetism is that the Earth's magnetic field behaves as a geocentric axial dipole (GAD) when averaged over sufficient timescales. Compilations of directional data averaged over the past 5 Ma yield a distribution largely compatible with GAD, but the distribution of paleointensity data over this timescale is ...

Reply to comment by F. Speranza et al. on “Recent eruptive history of Stromboli (Aeolian Islands, Italy) determined from high‐accuracy archeomagnetic dating” [PDF]

open access: yesGeophysical Research Letters, 2005
[1] We are grateful to Speranza et al. [2005] (hereinafter referred to as SSM) for the opportunity to clarify the respective merits of the ‘‘large sample’’ and ‘‘core-drilling and stepwise demagnetization’’ methods to determine paleomagnetic directions.
