| Abstract: | Summary The paper deals with the statistical approach to processing the polarity durations of the Earth's magnetic dipole over the past 170 million years. Partial elimination of the random component enables the mutual relation between normal and reversed polarities to be determined. The polarity time sequence has further been divided into several intervals. The frequency distributions for normal and reversed polarities have been established for each of these intervals. It has been found that the random component of the reversal triggering mechanism hides a pattern of behaviour which displays a certain amount of logic. |
