| 摘 要： | 根据海相层序地层理论和研究方法，通过对四川北部广元地区早、中三叠世沉积地层露头剖面的详细研究。划分出1个二级层序和6个三级层序。根据沉积层序和体系域的演化特征，编制了相对海平面变化曲线。通过区内沉积层序的划分对比，初步建立了广元地区早、中三叠世海相地层的层序地层格架。

| Abstract: | The Lower and Middle Triassic sedimentary strata in Guyangyuan region,Sichuan may be divided into I second-order sequence and 6 third-order sequences on the basis of the study of outcrop profile and by the use of theory and methodology of marine sequence stratigraphhy.A curve of relative fluctuation of sea level is compiled on the basis of sedimentary sequence and evolutionary characteristics of system domain.Stratigrapical framework of the Lower and Middle Triassic marine sequence stratigraphy in Guangyuan region is established on the basis of division and correlation of sedimentary sequences. |
