二十世纪六十年代以后兴起了固体地球物理学的崭新分支——板块构造学(plate tec-tonics)和板块运动学(Plate kinematics)。地学方面的这一新发展受到国内外科学界的重视,被誉为地学中的“革命”和“突破”。这一发展的来源在于对古地磁的研究、地震定位的精确化、深海钻探、和对海底及其地球物理场的大规模实地探测。海底扩张概念的提出标志着人们是从对海底的研究开始认识这
After the 1960s a new branch of solid geophysics emerged - plate tec-tonics and plate kinematics. This new development in geosciences has drawn the attention of the scientific community both at home and abroad and is known as “revolution” and “breakthrough” in geosciences. Sources for this development are paleomagnetic studies, the precision of seismic positioning, deep-sea drilling, and large-scale field exploration of the seabed and its geophysical fields. The concept of seabed expansion marks the beginning of the understanding of this from the beginning of the research on the seabed
