摘要

This paper presents the foundation of profile,divides 6 lithology section,confirms all kinds of deposit faciesminute facies and deposit system by studying the character of deposit. This paper divides small succession group, com-bines with interfacial succession. First pan-level and the greatest sea pan-level system and succession. This paper divides4 plus successions of early triassic epoch Feijian tan group in Pingle sag west section.%描述了创建剖面，划分了6个岩性段，并从沉积特征研究入手，确定了各种沉积相、微相及沉积体系。通过对小层序组划分，结合层序界面、首泛面和最大海泛面确定体系域和层序。在萍乐坳陷西段早三叠世飞剑潭组划分出4个正层序。
