Activity

Archaeomagnetism provides information about the variation of the Earth’s magnetic field in the past through the study of archaeological material. Archaeomagnetic dating is one of its most important applications, providing a powerful dating tool for archaeology by comparing the remanent magnetization measured on the undisturbed archaeological artefacts with reference secular variation (SV) curves which describe the variation of the geomagnetic field in the past for a certain geographical area (Fig. 1).

Our research group has a long experience on archaeomagnetic research, mainly focused on four principal research lines:

  1. The study of the direction and the intensity of the Earth’s magnetic field in the past through the investigation of ancient baked clays; 
  2. The reconstruction of the SV path during the last millennia and the establishment of reference SV curves;
  3. The archaeomagnetic dating of baked clay archaeological structures;
  4. The investigation of the magnetic properties, heating temperatures, production technologies and provenance of archaeological artefacts (e.g. pottery, ceramics, obsidians, etc).
