| The Canon of Marine Transgression and the Migration of Biotas during the Permo-Carboniferous in Asian East |
| 1. According to distribution of the faunas and floras, and the position of palaeoclimatic zones, it can be thought that geolgoraphically the position of the territory of Asian East during the Permo-Carboniferous does not very much differ from that of the present day.
2. On the basis of feature of biotas and strata in distribution, it is posiibly seen that along 42°N. Lat. there is an important boundary. North of the boundary is North Sea, South is South Sea.Situation of tuansgression of the two seas is completely different.
3. There is relation of growth adn decline of transgressions of the two Seas each other. During Early Carboniferous and Early Permian transgression takes place in North Sea, but regresion in South Sea. It shows that the seawater moves south to north ie. the Equator to the Arctic. During the Late Carboniferous and Late Permian the case jusu is opposite.
4. The migration of biotas and the movement of seawater keep in step.The agreement of the two kinds of motion means that there is certainly a more profound intermediate tie between the two. This tie had been hinted as climatic change by J. S. Lee rotation of the earth. But it has already gone beyond the limit of this paper . |
