Abstract: Volcanic records of the reversals of the geomagnetic field can be well matched under the assumption of a common reversal duration, and imply that the reversal process comprises three phases—a precursor, a fast polarity switch and a rebound—the properties of which have remained unchanged for about 180 million years.
