近十年来,发表了一系列古生代全球陆洋位置再造图。其中有些图在编制时只利用了古地磁资料,而另外一些图则同时使用了古地磁资料和地质资料。这些再造图虽然全较精确地表示了大陆的纬度分布位置,但却无法提供大陆漂移的经度分量。因此,这种图既不能用来计算古生代大洋的准确宽度(就象用板块运动学资料对中、新生代大洋所做的计算那样),也不能用来计算板 In the recent decade, a series of maps of the reoccurrence of the global continental ocean location have been published. Some of these maps used only paleomagnetic data when compiling, while others used both paleomagnetic data and geological data. Although these remanufactured plots fully represent the latitude distribution of the mainland, they can not provide the longitude component of the continental drift. Therefore, this map can neither be used to calculate the exact width of the Paleozoic ocean (as calculated using plate kinematics for Meso-Cenozoic oceans) nor can it be used to calculate the plate
