Further Evidence of High Intensity During the Levantine Iron Age Anomaly in Southwestern Europe: Full Vector Archeomagnetic Dating of an Early Iron Age Dwelling From Western Spain

Journal of Geophysical Research: Solid Earth, Volume 126, Issue 9, September 2021., 2021
Abstract We report an archeomagnetic study from the Early Iron Age archeological site of Cerro de San Vicente (Salamanca, Spain). The studied materials were sampled from one roundhouse and its central fireplace, a surrounding burnt floor, and slags with a twofold objective.

Correlation Based Time Evolution of the Archeomagnetic Field

Journal of Geophysical Research: Solid Earth, Volume 126, Issue 7, July 2021., 2021
Abstract In a previous study, a new snapshot modeling concept for the archeomagnetic field was introduced (Mauerberger et al., 2020, https://doi.org/10.1093/gji/ggaa336). By assuming a Gaussian process for the geomagnetic potential, a correlation‐based algorithm was presented, which incorporates a closed‐form spatial correlation function.

Bulk magnetic domain stability controls paleointensity fidelity [PDF]

, 2017
Nonideal, nonsingle-domain magnetic grains are ubiquitous in rocks; however, they can have a detrimental impact on the fidelity of paleomagnetic records—in particular the determination of ancient magnetic field strength (paleointensity), a key means of ...

Archeomagnetic dating in western North America: An updated reference curve based on paleomagnetic and archeomagnetic data sets [PDF]

Geochemistry, Geophysics, Geosystems, 2010
A robust database of paleomagnetic (PM) and archeomagnetic (AM) data for western North America covering the past 4 millennia is assembled from three data sets: (1) published PM data for dated lava flows, (2) recently published AM data generated by R. L. DuBois, and (3) published AM data generated by J. L. Eighmy. Chronologic information for the AM data

Magnetomineralogy of Archeomagnetic Materials.

Journal of geomagnetism and geoelectricity, 1996
A survey of the main magnetomineralogical characteristics of 92 archeomagnetic samples from 37 sites in Greece, Italy, North Africa, and China is presented. Coercive force spectra suggest that magnetite and/or titano-magnetite dominates both natural and laboratory remanences (NRM, ARM and IRM).

Intensity of the geomagnetic field in Europe for the last 3 ka: Influence of data quality on geomagnetic field modeling

Geochemistry, Geophysics, Geosystems, 2014
One of the main challenges of paleomagnetic research is to obtain high‐resolution geomagnetic field intensity reconstructions. For the last millennia, these reconstructions are mostly based on archeomagnetic data.

The impact of geomagnetic spikes on the production rates of cosmogenic 14C and 10Be in the Earth's atmosphere [PDF]

, 2015
We seek corroborative evidence of the geomagnetic spikes detected in the Near East ca. 980 BC and 890 BC in the records of the past production rates of the cosmogenic nuclides 14C and 10Be.

Archaeointensity study of five Late Bronze Age fireplaces from Corent (Auvergne, France) [PDF]

, 2016
International audienceRecent excavations at Corent (France) unearthed a vast Late Bronze Age settlement. The high density of fireplaces especially highlights it. The present study focuses on the archaeomagnetic study of five fireplaces.

New Archeomagnetic Directional Records From Iron Age Southern Africa (ca. 425–1550 CE) and Implications for the South Atlantic Anomaly

Geophysical Research Letters, 2018
The paucity of Southern Hemisphere archeomagnetic data limits the resolution of paleosecular variation models. At the same time, important changes in the modern and historical field, including the recent dipole decay, appear to originate in this region ...
