过去的活动已经掌握开创“新的地球学说”的板块理论,大致得到两种事实依据的支持。一是地震活动、地震波的传播方式以及海底热流量等反映现代板块运动的资料。二是残留着远古时代板块活动痕迹的种种记录。其代表是探索岩石生成时的地球磁场状况的古地磁学和记录着地磁倒转图 Past activities have mastered the theory of the plate that created the “new earth theory,” broadly supported by two factual bases. The first is the seismic activity, the propagation of seismic waves and the submarine heat flux, reflecting the movement of modern plate. The second is the remnants of ancient records of the activities of the plate track. Its representative is to explore the geomagnetism of the Earth’s magnetic field when the rock was generated and to record the geomagnetic reversal map
