| 摘 要： | 伊通地堑充填白垩系、下第三系、上第三系和第四系碎屑沉积物，厚约２０００～６０００ｍ。地堑内主要发育冲积扇体系、扇三角洲体系和湖泊体系，在地堑不同演化阶段分别构成６种沉积体系域类型．层序地层格架主要受控于构造、物源体系、湖的扩展及萎缩旋回和沉积中心分布。层序地层格架样式显示南北向隆回相间、东缓西陡的不对称式充填特征。

| Abstract: | Yitong graben filling sequence includes Cretaceous, Eogene, Neogene, Quaternary elastic deposits (thickness about 2 000-6 000 m). Alluvial fan system, fan--delta system and lacustrine system are developed in the graben. Six types of depositional system tracts occurs in different developing period of the graben. Sequence stratigraphic framework is mainly controlled by tectonics, sediment flux, expanding and contracting cycles and distribution of depositional centres, which shows the characteristics of asymmetric filling with slow eastern and steep western margin. |
