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).

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 ...

Uranium-Lead dating of hominid fossil sites in South Africa [PDF]

, 2005
Discoveries of hominid, or apeman, fossils in the twentieth century have brought human evolution into the scientific spotlight. It is important that ages are assigned to such hominids so that their place in human evolution can be established.

Recent Advances in Chinese Archeomagnetism

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.

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 ...

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 ...

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

Dating and Sex Among Emerging Adults in Nepal [PDF]

, 2010
Social and cultural changes in Nepal, including better communication facilities and transport, more urbanization and a rising age at which people marry, have created more opportunities for young people for “dating.” Our qualitative study explores ...

A Hierarchical Bayesian Model for the Global Holocene Geomagnetic Field

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.
Abstract We present a hierarchical Bayesian model of the global geomagnetic field for the last 8,000 years. The model is built solely with thermoremanent records, which include archeomagnetic and volcanic data. Building upon previous work, this model includes fewer approximations and treats model hyperparameters as probabilistic variables.

The Role of Culture in Intergenerational Value Discrepancies Regarding Intergroup Dating [PDF]

, 2010
This study examined cultural and generational differences in views on intergroup dating relationships among members of younger and older generation South Asian and European Canadians and the role of mainstream and heritage cultural identities in shaping ...
