摘要
It is suggested to perform chronostratigraphic division using type sections instead of boundary stratotypes, which are rather virtual units devoid of material content representing the respective deposition events. In this respect, global chronozones are more preferable for subdivision of stages than biozones poorly constrained in space and time. The stratotype-based approach to division of stages is advantageous, being associated with the deposition of chronostratigraphic units recorded in holo-and hypostratotypes. (C) 2015, V.S.
