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.

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.

The History of Italian Volcanoes Revised by Archeomagnetism [PDF]
Eos, 2009 The volcanoes Etna and Vesuvius are famous for their historical record, which goes back to Greek and Roman times. The name “Etna” first appears in one of Pindar's Pythian odes (475 B.C.E), and the Vesuvius outburst in 79 C.E. was reported in detail by Pliny the Younger.

High coercivity remanence in baked clay materials used in archeomagnetism [PDF]
Geochemistry, Geophysics, Geosystems, 2011 A study of the high coercivity remanence in archeological baked clays has been carried out. More than 150 specimens from 46 sites across Europe have been analyzed, selected on the basis of the presence of a fraction of their natural remanence that was resistant to alternating field demagnetization to 100 mT.

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 ...

Cooling Rate Correction in Paleointensity Experiments on Archeological and Geological Materials
Geochemistry, Geophysics, GeosystemsObtaining accurate estimates of the absolute intensity of the past geomagnetic field (paleointensity) is one of the major challenges in paleomagnetic research.

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

Transdimensional inference of archeomagnetic intensity change [PDF]
Geophysical Journal International, 2018 One of the main goals of archeomagnetism is to document the secular changes of Earth's magnetic field by laboratory analysis of the magnetization carried by archeological artefacts. Typical techniques for creating a time-dependent model assume a prescribed temporal discretisation which, when coupled with sparse data coverage, require strong ...

Archeomagnetism of Ontario potsherds from the last 2000 years [PDF]
Journal of Geophysical Research, 2000 An archeomagnetic study was carried out on potsherds samples from sites in Ontario with ages ranging from A.D. 90 to A.D. 1640 as determined by 14C dating. Thellier double‐heating paleointensity experiments were performed in air on 65 specimens of 52 samples from seven sample sets.
