Abstract: | The frequency distribution of intervals between Cenozoic geomagnetic reversals approximates a power law, while their occurrence over time shows temporal clustering of short and long intervals. Application of the Aggregate Variance and Absolute Value methods suggest long-range dependence in this time series, a possible indication that the geodynamo operates as a self-organised complex system. This hypothesis may allow the Cretaceous superchron to be considered as an integral part of the ordinary reversal regime attested in the Cenozoic record. |
