order sequence

From the standpoint of sequence stratigraphy, it is considered that Qom formation is a whole sedimentary cycle, being second-order sequence;

从层序地层学的角度分析认为：库姆组为一个完整的沉积旋回，属于二级层序；

The initial establishment of the third-order sequence of the study area.

初步建立了研究区三级层序。

Study result of third order sequence shows that the over-lap line was parallel with low stand offshore break, and offshore break belt dominated the distribution of stratigraphic over-lap reservoir.

三级层序为单元的研究表明，超覆线与低位坡折平行，坡折带控制了地层超覆的分布。

Form lith-facies succession to meter-scale cycle and from sedimentary-facies succession to third-order sequence, the Ordovician in studied area can devided into 8 third-order sequences, they are OS1~ OS8, which can be grouped into two second-order sequence. Tongzi Fm.

从岩相序列到米级旋回，从沉积相序列到三级层序，可以将研究区域的奥陶系划分为8个三级层序，即OS1至OS8。
