石炭纪(时间间隔大约为80m.y.)世界性生物地层地理分布的变化与冈瓦纳和欧美两个主要克拉通联结一起形成一个南北向的陆块环境相一致。后来,到早二叠世,西西伯利亚(安加拉古陆)与欧美大陆的北东侧,相连而形成泛古陆,是一个由南极延伸到北极一定范围内的超大陆。这些发展阶段示于图1—4中。冈瓦纳和欧美大陆的对接情况,对于非洲西北部和阿巴拉契亚造山带的接邻及南美洲Ouachita造山带的遥相对应也是适用的。
The changes in the geographical distribution of the biostratigraphy of the Carboniferous (at intervals of about 80 m.y.) are consistent with the formation of a north-south landform along with the two major Cratin bonds of Gondwana and Europe and the United States. Later, in the Early Permian, West Siberia (Angara Furukawa) was connected to the north eastern side of the European and American continents to form the Pangeaur. It was a supercontinent extending from the Antarctic to a certain extent within the Arctic. These stages of development are shown in Figure 1-4. Gondwana and European and American continents docking situation for the northwestern Africa Appalachian orogenic belt adjacent and Ouachita orogenic belt in South America is also applicable to the remote.
