First Full‐Vector Archeomagnetic Data From Central Asia (3 BCE to 15 CE Centuries): Evidence for a Large Non‐Dipole Field Contribution Around the First Century BCE

Journal of Geophysical Research: Solid Earth, Volume 129, Issue 2, February 2024.
Abstract Unraveling the short‐term behavior of the Earth's past geomagnetic field at regional scales is crucial for understanding its global behavior and, thus, the dynamics of the deep Earth. In this context, obtaining accurate full‐vector geomagnetic field records from regions where archeomagnetic data are absent becomes essential.

Correlation based modeling of the archeomagnetic field

, 2022
The geomagnetic main field is vital for live on Earth, as it shields our habitat against the solar wind and cosmic rays. It is generated by the geodynamo in the Earth’s outer core and has a rich dynamic on various timescales. Global models of the field are used to study the interaction of the field and incoming charged particles, but also to infer core

ARCHEOMAGNETISM IN BRAZIL: INTENSITY VARIATIONS OF THE EARTH\'S MAGNETIC FIELD FOR THE PAST FIVE CENTURIES

, 2010
O campo magnético da Terra varia em diferentes escalas de tempo, de milissegundos a bilhões de anos. Os dados de observatórios magnéticos e satélites obtidos nos últimos 150 anos indicam que o momento do dipolo magnético terrestre está diminuindo ...

An updated archeomagnetic directional variation curve for France over the past two millennia, following 25 years of additional data acquisition

, 2020
International audienceNearly 40 years ago, Emile Thellier published an article summarizing the archeomagnetic data he had obtained during his career, which had allowed him to recover the main features of the directional variations of the geomagnetic ...

An Interpretation of the Archeomagnetic Field Intensity

Journal of geomagnetism and geoelectricity, 1969
Available data of the ancient geomagnetic field intensity determined by the archeomagnetic measurement are compared with theoretically calculated curves of secular variation in the geomagnetic total force at three mutually remote sites. It is particularly remarkable that the anomalous archeomagnetic results from equatorial America (Peru, Bolivia and ...

Archeomagnetic Intensity Studies of South and Central America

Journal of geomagnetism and geoelectricity, 1965
Intensity of natural remanent magnetization of potteries from Peru, Bolivia and Mexico together with igneous rocks (lavas and pyroclastic rocks) from Mexico has been measured. The specimens cover the ages between about 0 A. D. and 1400 A. D. Most of the potteries and rocks have been found to contain magnetite or maghemite with titanium which is stable ...

Core-flow constraints on extreme archeomagnetic intensity changes

Earth and Planetary Science Letters, 2014
Recent studies (Ben-Yosef et al., 2009; Shaar et al., 2011) propose extreme archeomagnetic intensity changes (termed spikes) in the range ~4-5μT/year c.a. 1000 BC in the Near East, around 40 to 50 times larger than values typical of the present-day. In order to investigate whether such extreme changes are consistent with a model of the source region of
