Early Triassic conodont-palynological biostratigraphy of the Meishan D Section in Changxing, Zhejiang Province, South China

Conference Paper


Abstract


  • The Lower Triassic, consisting of the Yinkeng Fm., Helongshan Fm. and the lower part of the Nanlinghu Fm., is well developed at the Meishan D Section of Changxing County, Zhejiang Province, South China. Based on detailed study of the conodont biostratigraphy from the interval of the Permian-Triassic boundary and the Lower Triassic in the Meishan D Section, 8 conodont zones are recognized in ascending order as follows: the Neogondolella changxingensis yini-Hindeodus praeparvus Zone (beds 24a-24e, top of the Changxing Fm.), the Neogondolella meishanensis meishanensis-Hindeodus eurypyge Zone (beds 25-27b, base of the Yinkeng Fm.), the Hindeodus parvus Zone (beds 27c-27d, first conodont zone of Triassic, the global index for the base of Triassic), the Isarcicella staeschei Zone (beds 28-29a, lower part of the Yinkeng Fm), I. isarcica Zone (beds 29b-51, lower part of the Yinkeng Fm.), the Neogondolella tulongensis-N planata Zone (beds 52-72, from upper part of the Yinkeng Fm. to lower part of the Helongshan Fm.), the Neospathodus kummeli Zone (beds 73-92, middle part of the Helongshan Fm.), and the Neospathodus cristagalli-N dieneri Zone (beds 93-111, from upper part of the Helongshan Fm. to the base of the Nanlinghu Fm.). At the Meishan D Section, the palynological biostratigraphy is also studied herein. The palynological assemblage of Lundbladispora-Taeniaesporites-Equisetosporites is found in the intervals which contain the conodont Isarcicella isarcica Zone and the lower part of the Neogondolella tulongensis-N. planata Zone. © 2007 Elsevier B.V.
