过去地质时期岩石圈板块界限的复原是通过古地球动力图完成的。它指明每个具体时间幕中岩石圈板块的位置。归根结底,应当研究岩石圈板块过去运动的参数。古地球动力学重建是确定古大洋和古地理,特别是编制古深海图的基础。本文提供了24幅古地球动力图。最近7千万年以来的,以5百万年作间隔;从8千万年至1亿6千万年间,则以1千万年为间隔。复原工作是根据板块构造的常规方法,利用大洋线性磁异常、转换断层走向、以及大陆轮廓非常吻合等资料进行的。对下列磁异常时段进行
In the past, the restoration of lithospheric plate boundaries during the geological period was accomplished through paleo-earth dynamic diagrams. It indicates the location of the lithospheric plate at each specific time. After all, the parameters of past motion of lithospheric plates should be studied. Paleo-geodynamic reconstruction is the basis for the determination of paleoceanography and palaeogeography, especially the preparation of paleo-deep sea charts. This article provides 24 paleo-earth maps. The last 70 million years have been set at intervals of 5 million years; the interval between 80 and 160 million years has been set at 10 million years. The restoration work is based on the conventional method of plate tectonics using the linear magnetic anomaly in the ocean, the strike of the converted fault and the consistent contours of the continent. The following magnetic anomaly period
