Analysis of geomagnetic secular variation for the last 1.5 Ma recorded by volcanic rocks of the Trans Mexican Volcanic Belt: new data from Sierra de Chichinautzin, Mexico Open
The great wealth of volcanism along the Trans Mexican Volcanic Belt (TMVB) and the need to improve the secular variation curve of the Earth magnetic field of the region is the aim of this research. 300 oriented cores from 33 sites and 21 i…

Archéomagnétisme des terres cuites architecturales : nouvelles approches statistiques [communication orale] Open
Développée au milieu du XXe siècle par E. Thellier, l’archéomagnétisme est une méthode de datation chronométrique reposant sur l’enregistrement du champ magnétique terrestre (CMT) ambiant par les terres cuites au moment de leur cuisson. Le…

First Full Vector Archeomagnetic Data From Northern Mexico Open
Several regional secular variation curves of the geomagnetic field have been proposed for Mexico over the last millennia. Despite a fairly large number of archeomagnetic data, these curves remain imprecise because of an uneven quality and …
