自本世纪五十年代以来,古地磁学得到了迅速的发展.它不仅使人们发现了地磁极的迁移和倒转,而且对大陆漂移、海底扩张及板块学说的兴起也有较大的推动作用.经测定发现,不同大陆的地极迁移曲线是不同的,目前人们已认识到地磁极的迁移主要是大陆漂移的结果.因此,对各大陆地块的不同时代岩石进行古地磁研究,可以发现各个大陆的漂移规律.从目前已有的古地磁资料可以看出,亚洲大陆的形成和发展具有一个复杂的过程(附表).各种地质和地球物理资料表明,亚洲大陆主要是由几个前震旦纪结晶地块及其间的挤压褶皱带拼合而成,这些古老地块包括西伯利亚、科累马、松辽-布列亚、中朝、杨子、印支、印度、西藏、塔里木、准噶尔、哈萨克斯坦及阿拉伯地块等.通过古地磁测 Paleomagnetism has been rapidly developed since the 1950s, which not only makes people find the migration and inversion of the geomagnetic pole, but also plays a greater role in the development of the continental drift, seafloor expansion and plate theory. It has been found that the migration curves of the terrestrial poles are different in different continents, and it has been recognized that the migration of the geomagnetic poles is mainly the result of the continental drift. Therefore, paleomagnetic studies on rocks of different epochs in various continents can be found in various continents From the existing paleomagnetic data can be seen that the formation and development of the Asian continent has a complex process (Schedule) Various geological and geophysical data show that the Asian continent is mainly composed of several former Sinian Jiulong, Songliao-Briaas, Yangzi, Indo-China, India, Tibet, Tarim, Junggar, Kazakhstan and Arabian plots, etc ..
