Well-exposed, thick, marine stratigraphic sections with an abundance of both endemic and cosmopolitan Cambrian fossils are present in western Hunan, China. Such sections are exceptionally rare for the Cambrian System. Detailed collaborative study of the paleontology, biostratigraphy, and depositional environments of these Chinese sections is proposed. Reconnaissance sampling will also be made for stable-isotope analyses. With such study, the sections are expected to become important references for global biostratigraphic correlation, and possible stable-isotope correlation. They also are expected to be strong candidates for selection by the International Commission on Stratigraphy as world stratotypes for some stage and series boundaries within the upper half of the Cambrian System, and possibly as a stratotype for the Cambrian-Ordovician boundary.

中国湘西地区暴露良好的厚海相地层剖面，具有丰富的地方性和世界性寒武纪化石。这样的剖面在寒武纪非常罕见。建议对这些中国剖面的古生物学、生物地层学和沉积环境进行详细的合作研究。还将进行侦察取样以进行稳定同位素分析。通过这些研究，这些剖面有望成为全球生物地层对比的重要参考，并可能成为稳定同位素对比的参考。它们也有望被国际地层学委员会（International Commission on Stratigraphy）选为寒武系上半段某些阶段和系列边界的世界层型，并可能作为寒武-奥陶系边界的层型。
