Sequence Stratigraphy of the Permian-Triassia Boundary Section of Changxing, Zhejiang, Southern China

Three third–order sequences and about one hundred high–frequency cycles or Milankovitch cycles within the Late Permian Changxingian to Early Triassic Griesbachian are identified in the Meishan Section of Changxing, Zhejiang Province, southern China, the candidate stratotype section of the global Permo–Triassic boundary, based on a detailed study of the biological, ecological and high—resolution allochthonous cyclic events, microfacies and depositional systems. Furthermore, the stacking pattern of the depositional systems across various Changxingian and Griesbachian sedimentary facies of the Lower Yangtze and the sequence stratigraphic framework are outlined with the Meishan section as the principal section. In this paper the habitat types of fossil biota are applied to semiquantitative palaeobathymetry and the study of relative sea level changes.
