| 摘 要： | 本文通过对广丰县周家坞中奥陶统露头剖面层序、体系域、副层序的研究，识别出了三个不同性质的Ⅱ型层序界面和二个三级层序，确认这三个层序界面为符合实际又易于野外识别的自然界面，并对ＳＱ２中反映最大海泛期的高分辨异旋回驱动机制事件，提出可能受米兰柯维奇频率的春分点和秋分点间约２万年间隔的控制。

| Abstract: | Through a study on sequence stratigraphy,system domain and parastrata sequence of the Middle Ordovician outcrop profile in Zhoujiawu, Guangfeng County,three IItype sequence interfaces with different properties and two III-grade sequences were distinguished. These interfaces are real natural ones and are readily reognizable in the field. |
