Biostratigraphy and chronostratigraphy are common means of subdividing rock strata. The biostratigraphic succession and chronostratigraphic scheme are regarded as the basis for the subdivision and correlation of regional and global stratigraphic units. This paper reviews research on the biostratigraphy and chronostratigraphy carried out in the Jiangnan Slope Belt, South China since 1978, and, in particular, the biostratigraphic succession and chronostratigraphic scheme developed in the last decade. The updated biostratigraphic succession of South China includes 36 biozones, the base of each of which is defined by the first appearance of a single taxon (index fossil), and a poorly fossiliferous interzone. The updated chronostratigraphic scheme of South China comprises 4 series and 10 stages, embracing 3 global chronostratigraphic units, the Guzhangian Stage, Furongian Series, and Paibian Stage, and 2 GSSPs, all of which are erected in northwestern Hunan and 2 International Tie Points recognized in sections also in northwestern Hunan and each was accepted by the International Subcommission on Cambrian Stratigraphy for defining the base of the global stage. The biostratigraphic and chronostratigraphic systems are recognized as Chinese standards both domestically and worldwide. Future research is suggested for improving the two sets of stratigraphic standards.
