Abstract: | About twenty assemblage zones may be recognized: 5 belonging to the Upper Cretaceous, 3 to the Paleocene, 4 to the Eocene, 3 to the Oligocene and 5 to the Late Tertiary.The boundary between Cretaceous and Tertiary is discussed in the present paper based on palyno-logy.It is better to put the boundary between the lower and upper members of the Furao Formation than between the Furao anil Wuyin Formations. |
