First Full Vector Archeomagnetic Data From Northern Mexico

Geochemistry, Geophysics, Geosystems, 2021
Several regional secular variation curves of the geomagnetic field have been proposed for Mexico over the last millennia. Despite a fairly large number of archeomagnetic data, these curves remain imprecise because of an uneven quality and geographic ...

Synchronizing Geomagnetic Field Intensity Records in the Levant Between the 23rd and 15th Centuries BCE: Chronological and Methodological Implications

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 ...

Archeointensity of the Four Corners Region of the American Southwest

Geochemistry, Geophysics, Geosystems, 2020
New paleointensity experiments were conducted using the IZZI protocol (a variation on the Thellier‐Thellier method) on 289 specimens from 54 baked pottery fragments collected from four archeological sites in the American Southwest. Anisotropy experiments

Magnetic characteristics and archeointensity determination on Mesoamerican Pre-Columbian Pottery from Quiahuiztlan, Veracruz, Mexico [PDF]

Geofísica Internacional, 2008
We report a detailed archeomagnetic investigation on pre-Columbian potteries from Quiahuiztlan, Veracruz, from ~900 AD to 1521 AD. Archeological samples analyzed by modern magnetic techniques carry a stable univectorial thermoremanent magnetization under

Low Geomagnetic Field Intensity in Southern China 6,000 Years Ago

Geophysical Research Letters
The West Pacific Anomaly (WPA), a low geomagnetic field anomaly observed in the 16th to 18th centuries, represents a recently recognized and complex feature of Earth's magnetic field.

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.

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

Archeointensity estimates of a tenth-century kiln: first application of the Tsunakawa–Shaw paleointensity method to archeological relics

Earth, Planets and Space, 2018
Paleomagnetic information reconstructed from archeological materials can be utilized to estimate the archeological age of excavated relics, in addition to revealing the geomagnetic secular variation and core dynamics.

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 necessity of data availability in maintaining the value and longevity of paleointensity results

Frontiers in Earth Science, 2014
Asserting the reliability of paleointensity estimates, or comparing relative reliabilities between vastly or subtly different results is a key challenge for paleointensity studies, which often leaves interpretations of these data rife with ambiguities ...
