Holocene archeointensities from mid European ceramics, slags, burned sediments and cherts

Physics of the Earth and Planetary Interiors, 2015
Abstract The Earth’s geomagnetic field intensity in the past can be determined from archeological artifacts. These archeointensity data are important inputs for geomagnetic field models and local reference curves of Earth’s magnetic field. Although archeointensities have been measured on materials for more than half a century ago, data are still ...

An integrated magnetic, geochemical and archeointensity investigation of casting debris from ancient metallurgical sites of Michoacán, Western Mesoamerica

Studia Geophysica et Geodaetica, 2017
The ability of baked clay-elaborated objects to record the temporal variations of both direction and intensity of the geomagnetic field at the time of their elaboration or last use has been widely used during the last decades to fill the gaps left by available time-discrete volcanic-rock logs for a better knowledge of the evolution of the geomagnetic ...

Evidence for rapid geomagnetic field intensity variations in Western Europe over the past 800 years from new French archeointensity data

Earth and Planetary Science Letters, 2009
Abstract The number of reliable archeointensity determinations obtained from Western Europe for the past millennium remains limited. Moreover, the large scatter between different datasets available is puzzling. The present study analyzed 31 new groups of baked clay (ceramic or brick) fragments sampled in France (29 groups) and in Belgium (2 groups ...

Archeointensity results from El Papalote and Casas de Fuego furnaces, Chihuahua state, northern Mexico

, 2019
Despite the rich archaeological heritage of Mexico, the local secular variation curve of the Earth's magnetic field is still inaccurate, especially because of a lack of intensity data in the northern part of Mexico. We will present new archaeomagnetic data from a ceramic production area, the archaeological site of Casas de Fuego, located about 16 km SE

Archeointensity-based dating method: Examples from France and the Near-East

2021
While directional variations in the geomagnetic field are now widely used in archaeological practice in France to date fired structures found in situ after their abandonment, such as ceramic kilns or domestic ovens, the dating method based on geomagnetic field intensity variations is still under development.

Magnetic properties and Archeointensity of Earth’s magnetic field recovered from El Opeño, earliest funeral architecture known in Western Mesoamerica

Studia Geophysica et Geodaetica, 2010
Despite of the impressive cultural heritage and abundant archaeological sites, absolute geomagnetic intensity data from Mesoamerica are still sparse. Archeointensity determinations using the Coe variant of the Thellier and Thellier method have been carried out on some selected pottery fragments from the El Openo archeological site which has the ...

Archeointensity investigation on pottery vestiges from Puertas de Rolón, Capacha culture: In search for affinity with other Mesoamerican pre-Hispanic cultures

Studia Geophysica et Geodaetica, 2013
We report the results of a rock magnetic and archeointensity study on pottery fragments recovered at the archaeological site of Puertas de Rolón, Capacha culture (Colima), that is considered one of the most important pre-Classic cultural developments of western Mesoamerica, Mexico.
