We review the paleomagnetic methods used to obtain these data and discuss applications of the data within the database.

The database continues to expand as legacy data are added and new studies published. Databases are a vital component of the global infrastructure of science.

(2015)), in addition to a wider range of results from archeological and volcanic materials (‘Modifications and updates to the archeomagnetic and volcanic database’ section).

The same advantages apply to more modern paleomagnetic and rock magnetic data compilations based on relational databases (beginning with the IAGA Global Paleomagnetic Database (GPMDB), Lock and Mc Elhinny 1991; Mc Elhinny and Lock 1996; Pisarevsky 2005) that have now evolved the potential to store highly detailed information ranging from raw field and laboratory measurements through multiple processing steps to results (e.g., Mag IC, Constable et al. These data have a range of applications within geosciences.

The reader is referred to a companion publication for a description of the sediment database.

The archeomagnetic and volcanic part of GEOMAGIA50.v3 currently contains 14,645 data (declination, inclination, and paleointensity) from 461 studies published between 19.

GEOMAGIA50.v3 is a comprehensive online database providing access to published paleomagnetic, rock magnetic, and chronological data from a variety of materials that record Earth’s magnetic field over the past 50 ka.

Since its original release in 2006, the structure and function of the database have been updated and a significant number of data have been added.

The database is maintained in mirror versions on servers at the German Research Centre for Geosciences GFZ in Potsdam, Germany ( and at the University of California at San Diego, USA ( These models allow mapping of changes in the geomagnetic field at Earth’s surface and core-mantle boundary through time, placing constraints on the evolution of the past geomagnetic field.
