Cretaceous stage boundaries - Proposals

This paper is concerned with the chronostratigraphy of the Cretaceous System. It represents a compilation of the proposals that have resulted from the joint efforts of the three working groups of the Subcommis­sion on Cretaceous Stratigraphy, as presented at the symposium in Copenhagen 1983. The working groups are those on: the Pre-Albian, the Albian-Turonian, and the Coniacian-Maastrichtian.
