| 摘 要： | 湖北大冶沙田、阳新大王殿、通山新桥和崇阳港下的早三叠世生物地层的研究与火山事件沉积、沉积物注入和分布明显变化及陆上暴露标志研究相结合，建立了鄂东南地区早三叠世层序地层格架，划分出三个层序。将岩相（包括微相）分析与古生态研究相结合用以分析环境演变，发现在层序底界面缺乏暴露剥蚀条件下的层序由海侵体系域（ＴＳＴ）、凝缩层（ＣＳ）和高水位体系域（ＨＳＴ）组成。

| Abstract: | Based on the study of furly Triassic biostratigraphy,volcanic sedimentary events,the obvious variation of sediment input and dispersal and subaerial exposed markers in Shatian of Daye County,Dawangdian of Yangxin County,Xinqiao of Tongshan County and Gangxia of Chongyang County, this paper constructs the Early Triassic sequence stratisraphic framework and divides the southeast of Hubei Province into three sequences. By analysing the enviromental evolution according to facies(including mlcrofacies) and paleoecologic analyses, the author found that the sequence lackins exposed degradation on the sequence boundary consists of transgreedve systems tract (TST),condensed section (CS)and highstand systems tract(HST). |
