对海洋磁场分析确定的地磁极性间隔进行了统计分析。主要发现是统计结构在大约5000万年前经历了不连续的变化。极性间隔从0到48百万年。形成一个平稳序列，并由伽玛分布控制，但间隔不是独立的。极性间隔为56至72百万年，也是固定的，并且由伽马分布控制，但是具有不同的参数。间隔似乎是独立的。上述5600万至7200万年的结论由于数据有限，有些试探性。统计结构的不连续变化似乎与始新世早期全球构造活动相吻合。
Geomagnetic polarity intervals determined from the analysis of the marine magnetic field have been subjected to statistical analysis. The major finding is that the statistical structure undergoes a discontinuous change around 50 million years ago. The polarity intervals from 0 to 48 m.y. form a stationary sequence and are governed by gamma distribution, but the intervals are not independent. The polarity intervals from 56 to 72 m.y., are also stationary and are governed by gamma distribution but have different parameters. The intervals appear to be independent. The above conclusions for the period 56 to 72 m.y. are, on account of limited data, somewhat tentative. The discontinuous change in the statistical structure appears to coincide with the worldwide tectonic activity of the early Eocene.
