detachment fault

Genetic mechanism and geological significance of Mazhai detachment fault in Dongpu depression;

东濮凹陷马寨滑脱断层的形成机制及地质意义

A geometrical model,which utilizes an assemblage of parameters of propagation anticline to constraint the depth and geometry of the blind detachment fault,is figured in this paper based on both balanced geosection principles and previous studies.

滑脱断层断坡倾角为29°~45,°属于中等倾角。

The later one occurred in the end of Miocene and formed fault-slipped and salt-related structures.

Tokar地区位于苏丹红海南部水域,构造上属红海盆地中段西侧,先后经历了渐新世末和中新世末两次大的构造运动、裂陷—稳定—裂陷3个构造演化阶段,在盐上和盐下两个构造层形成了一系列构造圈闭:渐新世末主要形成基底卷入型构造,后中新世末则主要形成断层滑脱型构造和盐相关型构造,表现为潜山构造、披覆背斜、盐下原生背斜、盐上滚动背斜、盐上牵引背斜、盐拱背斜和盐墙遮挡圈闭等7种圈闭样式。
