摘要
福建古生界至中生界部分地层古地磁研究认为,华南地块的主体部分首先于中奥陶世时期即已拼合,作为一个整体由南纬23.8°向北移动,二叠纪之后越过赤道,继续北移,直至侏罗纪末到达北纬19.6°的位置.而华南地块同扬子地块的拼合是在加里东末期开始的,至少可以认为是在早石炭纪之前两地块就靠近了。这一时期,华南地块和扬子地块的地质构造运动十分活跃.
From palaeomagnetic research of Palaeozoic and Mesozoic strata of Fujian region, we concluded that the major parts; of the South China block was collided together during the mid-Ordovician Time and then began to move as a whole northwards from 23.8 S latitude. They strode across the equator after the Permian and reached its position at 19.6 N latitude in Late Jurassic Time. The South China block came into collision with the Yangtze block during the Caledonian. It may be at least assumed that the two blocks drew together before Early Carboniferous.
During that period, the two blocks were active in geological and tectonic movement.
