Recent Advances in Chinese Archeomagnetism [PDF]

Frontiers in Earth Science, 2017
The geomagnetic field is one of Earth's fundamental properties with a history of ~3.5 Gyr. The field, generated in Earth's core is a window to the deep interior of Earth and may have played a key role in evolution of life on our planet.

Short-Term Magnetic Field Variations From the Post-depositional Remanence of Lake Sediments

Frontiers in Earth Science, 2018
Paleomagnetic records obtained from lake sediments provide important constraints on geomagnetic field behavior. Secular variation recorded in sediments is used in global geomagnetic field models, particularly over longer timescales when archeomagnetic ...

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 Time Evolution of the Archeomagnetic Field

, 2021
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).

Full‐Vector Paleosecular Variation Curve for the Azores: Enabling Reliable Paleomagnetic Dating for the Past 2 kyr [PDF]

, 2021
For archeomagnetic dating, high-quality directional and intensity paleosecular variation curves are needed. The Azores Archipelago in the mid-Atlantic Ocean provides a wealth of volcanic products erupted during the Holocene, making it an ideal location ...

A multimethod paleointensity approach applied to the historical Xitle lava flows (Central Mexico): towards the accurate paleointensity determination

Earth, Planets and Space, 2020
An inclusive rock-magnetic and absolute paleointensity survey of the ~ 2-ka-old Xitle volcano (southerly Basin of Mexico) was undertaken to assess the faithfulness of the paleomagnetic log carried by fresh, widely exposed and well-preserved lava flows ...

Effects of Global Geomagnetic Field Variations Over the Past 100,000 Years on Cosmogenic Radionuclide Production Rates in the Earth's Atmosphere

Journal of Geophysical Research: Space Physics, Volume 128, Issue 8, August 2023., 2023
Abstract The production rates of cosmogenic radionuclides, such as 10Be, 14C, and 36Cl, in the Earth's atmosphere vary with the geomagnetic field and solar activity. For the first time, the production rates of several cosmogenic nuclides are estimated for the past 100 ka based on global, time‐dependent geomagnetic field models and a moderate solar ...

On the Suitability of Prehistoric Anthropogenic Burnt Sediments (Fumiers) for Archeomagnetic Studies at El Mirador Cave (Burgos, Spain)

, 2022
The analysis of the magnetic record of burnt archeological materials provides valuable information of both chronological and geophysical interest. Archeomagnetic studies carried out on independently well-dated materials allow to obtain data in order to ...

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
