Abstract
The increasing importance of sediments for paleomagnetic research
prompted a study of rockmagnetic parameters of natural goethite, pyrrhotite
and hematite. Grain-size dependent behaviour of such parameters is
poorly known for goethite and pyrrhotite as well as for fine-grained
hematite. Data of hematite indicate a complex rockmagnetic behaviour.
Existing data seem to be contradictory in many
