摘　　要：研究区三叠系可划分出3个沉积等时面、4个沉积体系和10个沉积类型。它们在横向上的相变和垂向层序上的组合特征显示了一种发育于碳酸盐台地之上的断陷盆地的特点。该盆地的发展和演化经历了稳定台地阶段、裂陷充填阶段和回返成陆阶段。In the study, area, the Triassic systems can be divided into 3 sedimentary isochronic planes, 4 depositional systems and 10 sedimentary facies. Their facies-change and the sedimentary sequences in lateral and in vertical show the character of the fault basin developed on a carbonate platform respectively . The development of the basin has undergone steady platform stage, fault fill stage and epeirogeny stage.
