The study of the spatial and temporal evolution of the geomagnetic field in the past is fundamental to understand the processes that take place in the Earth's external core and to obtain information about the geomagnetic field evolution at the core-mantle boundary. For the last decades, such information is provided by historical and instrumental data, while for older periods the investigation of archaeological material, volcanic rocks and sediments is necessary. In this session, we invite contributions that can offer information about the past geomagnetic field variations in both short and long timescales. Acquisition, measurements and elaboration of new records of palaeosecular variation, geomagnetic field reversals, magnetostratigraphy and cyclostratigraphy are welcome. The session solicits also contributions about regional and global palaeomagnetic databases, geomagnetic field modeling, Geomagnetic Polarity Time Scales (GPTS) and other magnetic methods applied in Earth Sciences.
