4. Archeomagnetism

Participating scientists

  • L.J. Pesonen, Project leader
  • F. Donadini, post doc (ETH, Switzerland)
  • M. Kovacheva and M. Kostadinova (Bulgarian Academy of Sciences)
  • K. Korhonen (Geological Survey of Finland)
  • E. Luoma-aho (M.Sc.)

Project goals

The goal is to define the geomagnetic field intensity at high latitudes in Finland during the past 7000 years. Another topic is to try archeomagnetic dating on mural paintings.
