A regional archeomagnetic model for Europe for the last 3000 years, SCHA.DIF.3K: Applications to archeomagnetic dating [PDF]

Geochemistry, Geophysics, Geosystems, 2009
The available European database of archeomagnetic field values and instrumental data has been used to produce a regional model for the geomagnetic field in Europe for the last 3000 years (from 1000 B.C. to 1900 A.D., connecting with the epoch covered by the IGRF models).

Correlation based snapshot models of the archeomagnetic field [PDF]

Geophysical Journal International, 2020
SUMMARY For the time stationary global geomagnetic field, a new modelling concept is presented. A Bayesian non-parametric approach provides realistic location dependent uncertainty estimates. Modelling related variabilities are dealt with systematically by making little subjective a priori assumptions. Rather than parametrizing the model

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.

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

High‐Fidelity Archeointensity Results for the Late Neolithic Period From Central China [PDF]

, 2020
Archeomagnetism focuses on exploring high-resolution variations of the geomagnetic field over hundreds to thousands of years. In this study, we carried out a comprehensive study of chronology, absolute and relative paleointensity on a late Neolithic site

Archeomagnetic intensity variations during the era of geomagnetic spikes in the Levant [PDF]

Physics of the Earth and Planetary Interiors, 2021
Observational records of rapidly varying magnetic fields strongly constrain our understanding of core flow dynamics and Earth's dynamo. Archeomagnetic analyses of densely sampled artefacts from the Near-East have suggested that the intensity variation during the first millennium BCE was punctuated with two geomagnetic spikes with rates of change of ...

Updated Iberian Archeomagnetic Catalogue: New Full Vector Paleosecular Variation Curve for the Last Three Millennia

Geochemistry, Geophysics, Geosystems, 2018
In this work, we present 16 directional and 27 intensity high‐quality values from Iberia. Moreover, we have updated the Iberian archeomagnetic catalogue published more than 10 years ago with a considerable increase in the database.

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 ...

An archeomagnetic example of polyphase magnetization.

Journal of geomagnetism and geoelectricity, 1986
An unusual archeological example of multiple heating leading to superimposed thermoremanent magnetizations (TRM's) is described. The samples involved are roof-tiles which have been incorporated into the floor of a 6th century A. D. kitchen oven at a site near Potenza in southern Italy. Up to 300°C, thermal demagnetization reveals a pattern of diverging
