前言东亚是研究地壳断块增生的理想天然场所。古地磁学是有效地确定相对运动量的主要手段之一。尽管古地磁研究数量迅速增加,但至今关于一些大断块,例如西伯利亚,华北或华南断块还没有足够而可靠的显生宇数据(Lin 等,1985)。虽然对西伯利亚(即欧亚)断块和中国断块之间古磁极差异的解释仍然不一致(Full 等,1987),但晚中生代的研究结果是充分的,并对于侏罗纪和更年青年代取得较一致的意见。朝鲜习惯上被认为是华北断块(中朝)的一部分,在东亚的任何构造分析中因朝鲜而造成了更多的不确定性。然而,在现在许
Foreword East Asia is an ideal natural place to study the growth of crustal blocks. Paleomagnetism is one of the main means to determine the relative movement effectively. Despite the rapid increase in the number of paleomagnetic studies, so far there is not enough reliable solar phantom data for some large faults such as Siberia, North China or South China (Lin et al., 1985). Although the interpretation of paleomagnetic differences between the Siberian (ie, Eurasian) and Chinese fault blocks is still inconsistent (Full et al., 1987), the results of the Late Mesozoic studies are adequate and for Jurassic and even younger generations More consistent opinion. North Korea is customarily considered part of the North China block (China-North Korea) and has created more uncertainty in North Korea due to any tectonic analysis in East Asia. Now, however
