古地磁场

古地磁场强度、古地磁场极性倒转比例、古地磁场极性倒转频率和真极移速率在地史上均呈周期变化，与开合构造关系密切，同受全球性因素制约。

The intensity of palaeomagnetic field , the proportion and frequency of palaeomagnetic polarity reversal , and the rate of true polar wandering may display the periodic changes in the geological history and are closely related to the opening and closing , and may be restricted to the global factors .
