The dawn of archeomagnetic dating [PDF]

open access: yesComptes 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.

Geomagnetic spikes on the core-mantle boundary. [PDF]

open access: yesNat Commun, 2017
Extreme variations of Earth’s magnetic field occurred in the Levant region around 1000 BC, when the field intensity rapidly rose and fell by a factor of 2.

Reconstructing the Geomagnetic Field in West Africa: First Absolute Intensity Results from Burkina Faso. [PDF]

open access: yesSci Rep, 2017
We present absolute geomagnetic intensities from iron smelting furnaces discovered at the metallurgical site of Korsimoro, Burkina Faso. Up to now, archaeologists recognized four different types of furnaces based on different construction methods ...

Bulk magnetic domain stability controls paleointensity fidelity. [PDF]

open access: yesProc Natl Acad Sci U S A, 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 ...

Decadal Geomagnetic Secular Variations From Greigite Bearing Dead Sea Sediments

open access: yesGeochemistry, Geophysics, Geosystems, 2021
Archeomagnetic data from the Levant revealed periods within the Holocene with fast and extreme changes in the geomagnetic field. Yet, the availability of the archeomagnetic data is sporadic and the correlation with the available sedimentary records from ...

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 [PDF]

open access: yesJournal of Geophysical Research: Solid Earth, 2021
AbstractWe 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.

A complementary, two-method spherical approach to direction-based archeomagnetic dating

open access: yesJournal of Archaeological Science, 2023
We present a two-method spherical approach to archeomagnetic dating based on directional variations of the geomagnetic field after vector treatment of all data, including individual in situ structure-level data used to calculate the reference variation curve and the archeomagnetic direction to be dated. In this paper, the reference curve for France was

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

open access: yesGeochemistry, 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]

open access: yes, 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

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

open access: yesGeochemistry, 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).
