陆东断陷是开鲁盆地的次级断陷，形成于中生代，基底断裂可分为北北东向和近东西向两组。北北东向基底断裂组主要分布于盆地东部；近东西向基底断裂主要分布于盆地西部。根据这两组基底断裂的特征及其对盆地内侏罗系地层及岩相的控制规律，认为北北东向基底断裂对盆地形成及演化起控制作用。据此，进行了构造应力场模拟，盆地形成及盖层变形均受控于北北东向断裂，其顺扭运动使盆地下陷接受沉积，其反扭运动使盖层产生有规律的变形。
The Luodong fault depression is a secondary fault depression of the Kailu Basin and was formed in the Mesozoic. The basement faults can be divided into two groups: north-north east and east-west. The NE-trending basal faults are mainly distributed in the eastern part of the basin. Basal-proximal faults are mainly distributed in the western part of the basin. Based on the characteristics of these two sets of basement faults and their control over the Jurassic strata and lithofacies in the basin, it is believed that the NE-trending basal faults play a controlling role in basin formation and evolution. Based on this, the tectonic stress field simulation was carried out. The formation of the basin and the deformation of the cover are controlled by the north-north eastward fault. The cis-twisting motion subsides the basin to accept sedimentation, and the anti-torsional movement causes the cap layer to have regular deformation.
