摘　　要：为了厘清广元-旺苍地区下三叠统飞仙关组层序地层充填过程和鲕粒滩的发育、演化及纵向分布规律,明确鲕粒滩发育有利区带,本次研究基于Vail层序地层学理论,利用岩心、薄片、露头和测井等资料,进行了层序界面识别、层序单元划分、等时地层格架建立,开展层序地层、层序演化及鲕粒滩发育和分布规律研究。In order to clarify the sequence stratigraphic filling process,and the development,evolution and vertical distribution of oolitic shoals of Feixianguan Formation in of lower Triassic Guangyuan-Wangcang area.Based on the Vail sequence stratigraphy theory and using core,thin section,outfall and logging data,this study identified sequence interfaces,divided sequence units,established isochronous stratigraphic framework,and carried out research on sequence stratigraphy,sequence evolution,and development and distribution of oolitic shoals.
