摘要
四川彭县小渔洞地区下三叠统飞仙关组，常伴随二叠系飞来峰灰岩出现。该文着重介绍了丙寅沟出露较好的飞仙关组地层剖面，分析岩石组合特征（基本层序的划分、顶底界线讨论等）、动物群面貌（着重介绍Ｃｌａｒａｉａｗａｎｇｉ和Ｃ．ｓｔａｃｈｅｉ化石带），并与同期地层对比。
The Feixianguan Formation of Lower Triassic series in Peng County often appears with the limestone of Permian klippen. This paper emphatically describes the Feixianguan Pormation stratigraphic section outcroped in Bingyingou,analyzes the rock assemblage characteristics (division of the primary sequences,discussion of the top and bottom boundary of the Feixianguan Formation, …… ),fauna features (especially the two bivalve fossil zones, Claraia wangi zone and C. stachei zone), and compares the section with the strata of the same stage. This research is of practical significance to the recognization of the features of the Feixianguan Formation in this region.
