| 摘 要： | 南翼山-尖顶山地区位于柴达木盆地西北部,与阿尔金斜坡带毗邻,一系列北西向紧闭背斜和夹于其间的宽缓向斜构成了本区的构造格架.研究区自中生代以来主要经历了两个阶段的变形作用:(1)在早-中侏罗世,主要受到伸展作用控制,形成箕状断陷;(2)狮子沟期-现在,一直受到SW-NE向挤压作用.尖顶山背斜自狮子沟期开始形成,其下伏早期控陷正断层由于挤压发生反转作用,形成了大型断层传播褶皱;南翼山背斜自七个泉期开始形成,由深部、浅部两个背斜构造叠合而成,深部为一大型断层转折褶皱,浅部为构成Ⅰ型构造三角带的两个台阶状逆冲断层的相向逆冲作用在断层上部形成一个类似于滑脱褶皱的箱状背斜.南翼山背斜、尖顶山背斜的形态比较完整,构造形成时间与油气成熟、运移的时间匹配良好,具有十分有利的油气勘探前景. |

| Abstract: | Nanyishan-Jiandingshan area is in the northwest of Qaidam Basin,and it is adjacent to Aerjin slope zone.A series of NW trending tight anticlines and the gentle synclines in the between constitute the structural framework of the area.Research shows the study area underwent mainly two stages of deformation since Mesozoic:(1)during Early to Middle Jurassic,the area was mainly dominated by extension and featured by the formation of the dustpan-like faults;and(2)during Shizigou Period to present,the area has bee... |
