简介:对从中国大陆人和邻近的块的白垩纪paleomagnetic数据寒武纪用原则被收集获得可靠、高精确的paleomagnetic数据并且注意paleobiogeography和构造进化的协作的类似。中国大陆人块在建议全球paleocontinents的重建上被贮藏与几乎一样的规模。因此,包括中国大陆人块,全球大陆在赤道的南部的方面上沿着纬度变化在期间,这能清楚地被认出早古生代。在古生代的、中国大陆人,块仍然在Laurentia,西伯利亚和Gondwana盘子之中位于,跟随向北的西伯利亚板的快移动,在在Laurentia和Gondwana盘子的西方的部分的一个纵贯的方向的合并,和Iapetus和Rheic海洋是subducted,最后形成一致Pangea在晚古生代。东方Gondwana的澳大利亚、印度的盘子向南逐渐地移动了并且分散,继续扩大Paleo-Tethys海洋。中国大陆人和邻近的块仍然位于Paleo-Tethys海洋,保存了分散的地位,逐渐地向北移动,沿着northsouth取向变化直到的出现特征二叠。另外,一系列本地碰撞发生了在期间三叠纪,并且因而,大多数中国大陆人块被混合进Pangea,除了Gangdise和喜玛拉雅的块。有在侏罗记的东方亚洲大陆的逆时针方向的旋转,向北,在在白垩纪期间改变度的中国大陆的移植,而是喜玛拉雅、印度的盘子没在这个时期期间碰撞进中国大陆。
