Version 3 has been updated with a new web interface. It allows users to search for magnetic and chronological data recorded in archeological and volcanic materials, and a new search interface has been designed to recover data from lake and marine sediments over the past 50 ka. We recommend the use of version 3 from this point on, but preserve version 2 in case any user wishes to compare the data sets available in versions 2 and 3.

If you use version 2 of the database, please cite it using the following references: The GEOMAGIA50.v2 interface allows:
  • selecting and saving archeomagnetic data based on various constraints.
  • calculating the ARCH3k.1, CALS3k.3, CALS3k.4, CALS7k.2, and CALS10k.1b global models field at any location and save them as text files. Some explanations about the various models can be found here.
  • plotting data and models in time.
