摘要
通过对岩石组合、基本层序、沉积相和古生物的系统研究及野外露头层序界面的识别和追索,初步将本区早、中三叠世地层划分为7个由海侵体系域(TST）和高水位体系域（HST）组成的三级层序,归并为2个层序组,据沉积层序演化特征编制的海平面变化曲线可与扬子地台其他地区及国外进行对比。
Based on systematical study on rock assemblages, primary sequence, sedimentary facies and biological assemblages and comparison study of eustatic curves in other areas of the Yangtze platform as well as abroad, the Lower-Middle Triassic in Wushan area can be divided into two sequence sets and seven three-order sequences composed of transgressive system tract (TST) and highstand system tract (HST).
