New archeomagnetic secular variation data from Central Europe, II: Intensities
Physics of the Earth and Planetary Interiors, 2020Abstract Variations of the geomagnetic field during the past millennia can be obtained by investigating archeological material. The spatial distribution of the available data across Europe is rather uneven and only about 15% of the sites provide a full vector record of the geomagnetic field.

Archeomagnetic results from Spain
2007A first secular variation (SV) curve for the Iberian Peninsula was computed by hierarchical Bayesian method using a total of 134 archaeomagnetic directions with ages ranging from 775 BC to 1959 A.D. A general agreement is observed between the Iberian curve and the French and German SV curves, excepted between the 11th and 14th centuries.

Archeomagnetic dating of Mediterranean volcanics of the last 2100 years: validity and limits
Earth and Planetary Science Letters, 2003Archeaeomagnetic dating developed at St. Maur laboratory has been applied to the Mediterranean volcanoes Etna, Vesuvius and Ischia. The method involves samples from lava flows or high temperature emplaced pyroclasts (welded scoriae, pumice, etc.) weighing 0.5-1 kg each, that allows reaching a precision of a few tenths of a degree on the direction of ...

Archeomagnetism of a 19th century pottery kiln near Jordan, Ontario
Canadian Journal of Earth Sciences, 1980The Jordan pottery kiln near St. Catharines, Ontario, was last fired about 1840–1841. Bricks from the kiln floor have intense NRM's (natural remanent magnetizations) in the range 0.2 × 10−2 to 3.7 × 10−2 emu cm−3 which are directionally stable against alternating field (AF) demagnetization to 1000 Oe (7.96 × 104 A/m).

The Global Archeomagnetic Database: Updates to GEOMAGIA50
2019Compilations of archeomagnetic data are fundamental to our understanding of the evolution of Earth’s magnetic field on centennial to millennial time scales. From the earliest studies of the Thelliers, Aitken, Nagata and others in the 1950s and 1960s, who obtained directional and paleointensity data from artefacts from Europe, the Near East, Asia and ...
