A Lake Record of Geomagnetic Secular Variations for the Last 23 ka From Lake Chala: Toward a Composite Directional Lake Record of the Earth's Magnetic Field for Equatorial East Africa

open access: yesGeochemistry, Geophysics, Geosystems, Volume 25, Issue 3, March 2024.
Abstract The documentation and understanding of variations in the Earth's magnetic field through time is fundamental for several disciplines, but current geomagnetic models rely on datasets heavily biased toward the mid‐ and high northern latitudes. The African continent and surrounding islands and oceans are particularly underrepresented.

A Bayesian analysis of luminescence dating [PDF]

open access: yes, 2008
Luminescence dating is a widespread dating method used in the fields of archaeology and Quaternary science. As an experimental method it is subject to various uncertainties in the determination of parameters that are used to evaluate age.

Fire Along the Street of the Dead: New Comprehensive Archaeomagnetic Survey in Teotihuacan (Central Mesoamerica)

open access: yesQuaternary
Teotihuacan, one of the most significant urban and ceremonial centers of ancient Mesoamerica, was abruptly abandoned in the mid-1st millennium AD. The cause and timing of its collapse—commonly placed between 600 and 650 AD—remain major questions in ...

Cracking the code of Earth's magnetic mysteries: ancient secrets unveiled by byzantine bricks reconfirmed by Mesopotamian ceramics

open access: yesProceedings (European Academy of Sciences and Arts)
The study of the magnetization of artifacts discovered at archaeological sites, such as ceramics or hearth remnants, is known as archaeomagnetism. This technique is based on the idea that some materials get magnetized in the direction and intensity of ...

Developing archaeomagnetic dating in the British Iron Age. [PDF]

open access: yes, 2011
Archaeomagnetism is an area of research that utilises the magnetic properties of archaeological materials to date past human activity. This research aimed to use the evidence of past geomagnetism, as recorded by archaeological and geological materials,

Developing Archaeomagnetic Dating for Neolithic Scotland

open access: yes, 2019
Studying the past geomagnetic field preserved in fired archaeological features such as hearths, furnaces, or kilns, allows dating of their last use and provides crucial information about the behaviour of the geodynamo.
