| 摘 要： | This paper proposes a scheme for the definition of the Lower Triassic Induan-Olenekian boundary(IOB) based on investigation of sections in Chaohu, Anhui Province, China as well as data accunulated from other studies elsewhere. The conodont Neospathodus waageni is suggested as the index fossil of the boundary. According to the FAD of N.waageni, the IOB is at the base of bed 25-2 of the West Pingdingshan Section in Chaohu,42.19 m above the Permian-Triassic boundary, and it is slightly higher than the base of the Flemingites-Euflemingites Ammonoid Zone at the section.
