Low Geomagnetic Field Intensity in Southern China 6,000 Years Ago

Geophysical Research Letters
The West Pacific Anomaly (WPA), a low geomagnetic field anomaly observed in the 16th to 18th centuries, represents a recently recognized and complex feature of Earth's magnetic field.

Further Evidence of High Intensity During the Levantine Iron Age Anomaly in Southwestern Europe: Full Vector Archeomagnetic Dating of an Early Iron Age Dwelling From Western Spain [PDF]

Journal of Geophysical Research: Solid Earth, Volume 126, Issue 9, September 2021., 2021
Abstract We report an archeomagnetic study from the Early Iron Age archeological site of Cerro de San Vicente (Salamanca, Spain). The studied materials were sampled from one roundhouse and its central fireplace, a surrounding burnt floor, and slags with a twofold objective.

First archeointensity results from Portuguese potteries (1550-1750 AD) [PDF]

Earth, Planets and Space, 2009
Abstract Geomagnetic field variations at archeomagnetic timescales can be obtained from well-dated heated structures and archeological potsherds. Here, we present the first archeointensity results obtained on Portuguese ceramics (1550 to 1750 AD) collected at Brazilian archeological sites.

Paleointensity Study on the Holocene Surface Lavas on the Island of Hawaii Using the Tsunakawa–Shaw Method [PDF]

Frontiers in Earth Science, 2018
Investigating volcanic paleointensity during the Holocene is important for linking archeointensity and sedimentary paleointensity. Across the globe, the island of Hawaii is one of the most studied subaerial locations.

Analyzing the geomagnetic axial dipole field moment over the historical period from new archeointensity results at Bukhara (Uzbekistan, Central Asia)

Physics of the Earth and Planetary Interiors, 2021
Abstract Since the mid-19th century, direct measurements of both intensity and directions of the Earth's magnetic field have been available, allowing an accurate determination of its spatio-temporal variations. Prior to this time, between ∼1600 and 1840, only direct directional measurements are available.

New Late Neolithic (c. 7000–5000 BC) archeointensity data from Syria. Reconstructing 9000years of archeomagnetic field intensity variations in the Middle East [PDF]

Physics of the Earth and Planetary Interiors, 2015
We present new archeomagnetic intensity data from two Late Neolithic archeological sites (Tell Halula and Tell Masaikh) in Syria. These data, from 24 groups of potsherds encompassing 15 different time levels, are obtained using the Triaxe experimental protocol, which takes into account both the thermoremanent magnetization anisotropy and cooling rate ...

New archeointensity results from Teotihuacan (Central Mexico).

, 2007
We carried out systematic rock-magnetic and archeointensity invetigations on 84 pottery fragments (about 549 samples) of Teotihuacan ceramics. Three localities are sampled: Xalla, Teopancazco and Cueva de las Varillas. The principal aim of this study is to try to establish first archeointensity reference curve for Mesoamerica from 300 a.C. and 1500 d.C.

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.

Improving our knowledge of the rapid geomagnetic field intensity variation observed in Europe around 800 AD: new archeointensity data from Visigothic Spanish potteries

, 2011
Despite the increase in archeomagnetic studies in the past few years, the number of reliable archeointensity data is still limited. For example there are only four published archeointensity data for Western Europe for the period between the 8th and the beginning of the 10th centuries.

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
