Recent Advances in Chinese Archeomagnetism [PDF]
Frontiers 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.

Archeomagnetic Intensity Spikes: Global or Regional Geomagnetic Field Features? [PDF]
Frontiers in Earth Science, 2018 Variations of the geomagnetic field prior to direct observations are inferred from archeo- and paleomagnetic experiments. Seemingly unusual variations not seen in the present-day and historical field are of particular interest to constrain the full range

Archaeomagnetism in the Levant and Mesopotamia Reveals the Largest Changes in the Geomagnetic Field. [PDF]
J Geophys Res Solid Earth, 2022 Abstract Our understanding of geomagnetic field intensity prior to the era of direct instrumental measurements relies on paleointensity analysis of rocks and archaeological materials that serve as magnetic recorders. Only in rare cases are absolute paleointensity data sets continuous over millennial timescales, in sub‐centennial resolution, and ...

The dawn of archeomagnetic dating [PDF]
Comptes Rendus. Géoscience, 2021 The use of secular variation in Earth’s magnetic field for dating purposes in archeology and volcanology began with the first developments in paleomagnetism.

Correlation based time evolution of the archeomagnetic field [PDF]
Journal of Geophysical Research: Solid Earth, 2020 In a previous study, a new snapshot modeling concept for the archeomagnetic field was introduced (Mauerberger et al. 2020). By assuming a Gaussian process for the geomagnetic potential, a correlation based algorithm was presented, which incorporates a closed form spatial correlation function.

Geochemistry, Geophysics, Geosystems, 2020 Archeomagnetic records are an important source of information on the past behavior of the geomagnetic field. Frequently, however, coeval archeomagnetic intensity (archeointensity) datasets from nearby locations display significant discrepancies ...

Modeling geomagnetic spikes: the Levantine Iron Age anomaly
Earth, Planets and Space, 2023 The Levantine Iron Age anomaly (LIAA) is a regional short-decadal geomagnetic strength field variation located at the Levantine region characterized by high intensities with maximum virtual axial dipole moments around 190 ZAm2. It has been constrained by

ArchKalmag14k: A Kalman‐Filter Based Global Geomagnetic Model for the Holocene
Journal of Geophysical Research: Solid Earth, Volume 127, Issue 2, February 2022., 2022 Abstract We propose a global geomagnetic field model for the last 14 thousand years, based on thermoremanent records. We call the model ArchKalmag14k. ArchKalmag14k is constructed by modifying recently proposed algorithms, based on space‐time correlations. Due to the amount of data and complexity of the model, the full Bayesian posterior is numerically
