层型
A candidate of the Induan-Olenekian boundary stratotype in the Tethyan region. 安徽巢湖地区早三叠世菊石序列.
It is proposed here that the formation stratotype should be changed to the Chuangde section. 建议将建组剖面改在床得剖面。
Key of the terrestrial stratotype establishment is to discover a sediment-successive section with rich fossils and complete exposure. 建立陆相层型的关键是找到沉积连续、化石丰富和暴露完全的剖面。

A new formal formation-rank lithostratigraphic unit-Ringtor Formation-has been established based on detailed measurements of a stratotype section and comparative study. 通过详细的层型剖面测制和对比研究，将其新建为组级岩石地层单位-仁多组。
