Global archaeomagnetic data: The state of the art and future challenges
TL;DR: In this article, the authors give an overview of the widely used global archaeomagnetic database GEOMAGIA50, discuss the methods used to obtain archaeological data, their challenges, and explore progress over the past twenty years in developing regional secular variation curves and global spherical harmonic models of the geomagnetic field.

SCHA.DIF.4k: 4,000 years of paleomagnetic reconstruction for Europe and its application for dating
F. Javier Pavón-Carrasco,Saioa A. Campuzano,M. Rivero-Montero,Alberto Molina‐Cardín,Miriam Gómez-Paccard,M. Luisa Osete +5 more
TL;DR: In this paper, an updated regional archaeomagnetic model, called SCHA.DIF.4k, for the European continent and adjacent areas and now covering the last four millennia is presented.
Journal ArticleDOI
Archeomagnetic intensity variations during the era of geomagnetic spikes in the Levant
TL;DR: In this paper, the authors apply a transdimensional Bayesian method designed to capture variations on both long and short timescales, and show that the data considered only at the fragment (thermal unit) level require a complex intensity variation with no less than six spikes, each with an approximate duration of between 30 and 100 years.

Archeomagnetic intensity investigations of French medieval ceramic workshops: Contribution to regional field modeling and archeointensity-based dating
Agnès Genevey,Yves Gallet,Erwan Thébault,Philip W. Livermore,Alexandre Fournier,Sébastien Jesset,Annie Lefèvre,N. Mahé-Hourlier,E. Marot,S. Regnard +9 more
TL;DR: In this paper, the Triaxe magnetometer was used for the analysis of pottery and kiln fragments from ceramic workshops unearthed in France, precisely dated from the High Middle Ages, which provided evidence of an intensity minimum that occurred around the transition between the 7th and 8th century.
Geomagnetic spikes on the core-mantle boundary
TL;DR: It is suggested that the Levantine spike reflects an intense CMB flux patch that grew in place before migrating northwest, contributing to growth of the dipole field.

The least-squares line and plane and the analysis of palaeomagnetic data
TL;DR: In this paper, principal component analysis is used to find and estimate the directions of lines and planes of best least squares fit along the demagnetization path of a palaeomagnetic specimen.

Sur l'intensite du champ magnetique terrestre dans le passe historique et geologique
Journal ArticleDOI
Geomagnetic paleointensities from radiocarbon‐dated lava flows on Hawaii and the question of the Pacific nondipole low
TL;DR: In this paper, the ages of basaltic lava flows on the island of Hawaii were investigated using the Thelliers' method in vacuum and the results showed that the dispersion of virtual geomagnetic poles for the eight lavas is 15.5°, appreciably larger than the average for older lava flows.
Journal ArticleDOI
Paleo-intensities of the Earth's magnetic field determined from Tertiary and Quaternary rocks
TL;DR: In this article, a variety of rock types from eighteen volcanic units of the western United States were studied by Thellier's method and the NRM-TRM curves were determined, and paleo-intensities are estimated from twelve of the units.
