| 摘 要： | 岩石圈的层状结构使拆离作用在沉积盆地中成为一种普遍发生的现象。拆离作用具有 4种岩石圈伸展模式。拆离构造具有发育剪切滑移带、多级次滑脱、构造形态上下不协调、发育动力变质岩和地层重复或缺失等特征。拆离作用形成的几种伴生构造可作为油气储集的地质体

| Abstract: | Detachment movements are taken place naturally in sedimentary basin because of the layered structure of the lithosphere.There are four kind of lithosphere extentional detachment fault models.The features of detachment structure are having sliding shear zone,multilevel detachment different types of up and down structure,rich in dynamometmophic rock and disappearing or overlapping of stratum.The associated structures of detachment movement are probablely advance units to oil and gas. |
