An integrated biostratigraphy (conodonts and foraminifers) and chronostratigraphy (paleomagnetic reversals, magnetic susceptibility, elemental chemistry, carbon isotopes and geochronology) for the Permian-Triassic strata of Guandao section

The chronostratigraphy of Guandao section has served as the foundation for numerous studies of the end-Permian extinction and biotic recovery in south China. Guandao section is continuous from the Permian-Triassic boundary to the Upper Triassic.

官道剖面（Guandao section）的年代地层学（chronostratigraphy）是华南地区诸多关于二叠纪末大灭绝（end-Permian extinction）与生物复苏（biotic recovery）研究的基础。该剖面的地层序列自二叠纪-三叠纪界线（Permian-Triassic boundary）至上三叠统（Upper Triassic）均保持连续。
