摘要
根据地球真极移和地壳运动关系的规律,以华北为例,阐明中国大陆南移的观点。从200Ma到180Ma的真极移,应在我国中部或西部。根据真极移引起地球形状调节的假说,大陆块从高纬度地区沿真极移面向赤道道运动时一般成为碎片,这和所见的地质现象一致。
According to0the law of relationship between true polar wander and crustalmovement, the idea of southward movement of the Chinese continent is expoundedwith reference to the North China example.It is found that the 200 Ma to 120 Maold wander plane should be situated in central or western China.On the basis ofthe hypothesis of earth shape adjustment, the continent that moved along the wan-der plane from high-latitude regions to the equator was fragmented. This is inaccordance with the tectonic record.
