萍乐坳陷西段早三叠世飞剑潭组的创建及地层层序研究

The Foundation of Early Triassic Epoch Feijian Tan Group and the Research of Stratum Succession 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。

This paper presents the foundation of profile,divides 6 lithology section,confirms all kinds of deposit facies minute facies and deposit systern by studying the character of deposit.This paper divides small succession group,combines with interfacial succession.First pan\|level and the greatest sea pan\|level system and succession.This paper divides 4 plus successions of early triassic epoch Feijian tan group in Pingle sag west section.
