"WebThe interval of time corresponding to a particular magnetic polarity zone is the magnetic chron, which has a typical duration of about 10 5 to 10 7 years. Subchrons are shorter intervals of opposing polarity within a chron and superchrons are longer intervals of dominantly normal, reverse or mixed polarity. " - Magnetic time scale
