| 摘 要： | 本文采用给每个岩石单元的古地磁极以单位权的方法,对目前收集到的、并按一定可靠性判据选择出来的华南和华北陆块的古地磁数据,进行了统计分析,绘制了它们的显生宙视极移曲线。进而根据古地磁结果,分析了两大陆块显生宙的构造演化,着重探讨了它们的碰撞时限和拼合过程。

| Abstract: | In this paper,Phanerozoic paleomagnetic poles for the North and South China blocks de- termined by rock samples which we have collected and selected according to reliable criteria are statistically analysed by assigning unit weight to each rock unit.Based on the statistical data,Phanerozoic apparent polar wander paths for both blocks are constructed,the tectonic evolutions and palinspastic reconstructions are discussed.Particularly,the collision time and the welding process are studied in detail. |
