Scope
|
This session is open to recent advances in all areas being concerned with geomagnetism, paleomagnetism and applications of magnetic methods to geophysical and geological issues. Papers are solicited which discuss geodynamo, present and past geomagnetic behaviors, fundamental rock magnetic properties, and paleoclimatic changes and tectonic processes revealed by magnetic methods.
