層型

A candidate of the Induan-Olenekian boundary stratotype in the Tethyan region. 安徽巢湖地區(qū)早三疊世菊石序列.

It is proposed here that the formation stratotype should be changed to the Chuangde section. 建議將建組剖面改在床得剖面。

Key of the terrestrial stratotype establishment is to discover a sediment-successive section with rich fossils and complete exposure. 建立陸相層型的關(guān)鍵是找到沉積連續(xù)、化石豐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. 通過詳細的層型剖面測制和對比研究，將其新建為組級巖石地層單位-仁多組。
