| 摘 要： | 在乌尔逊凹陷识别出四个区域性构造层序界面即T5、T3、T04、T02,将控陷发育阶段按构造层划分成三期：断陷期、断-坳转换期、坳陷-萎缩期。本次三维地震资料的重新解释得出，断陷期乌西控陷断层并非是一条南北向断层，而是由多条呈雁列展布的北东向断层组成，整条雁列式断裂带呈南北向展布；断-坳期则由多条近南北向控陷断层链接构成一条断裂．

| Abstract: | Urxun depression is identified in the four regional tectonic sequence boundaries that T5 ,T3 ,T04 ,T02, will be controlled by structural layers divided into three period ： fault - depression period, fault - sinking transition period, dawn - contraction period. As the re - interpretation of seismic data obtained, the depression - controlling fault of the western Urxun is not a north - south fault in fault - depression period, but by the number of en echelon distribution of north - east trending faults formed en echelon fault the whole north - south trending; a number of recent north - south link to constitute a fault rupture which controls the depression in fault - sinking transition period. |
