| 摘 要： | 显生宙以来,地磁场有7次频繁倒转间断,每次倒转伴随有相应的造山运动及岩浆活动。地磁场频繁变化,与之相伴的造山运动的发生,大陆与大洋的构造运动、生物的大量灭绝等,都与太阳系在银河系中的活动有关。

| Abstract: | During the Phanerozoic, the geomagnetie field frequently reversed. Seven epochs may be distinguished, each corresponding to one period of orogenesis and magmatism. The author believes that the frequent reversals of the geomagnetic field might be closely related to the motion of the solar system in the Milky Way. The relationships of the reversals with the mass extinction, divergence or convergence of cantinents and orogensis are also discussed in this paper. |
