摘要: 对准噶尔盆地周缘断裂构造进行了系统整理和分析, 查清了周缘主要断裂的空间展布特征; 在准噶尔盆地褶皱基底、结晶基底和莫霍面三维构造分析的基础上, 厘定了准噶尔盆地近东西向和近南北向的岩石圈断裂, 其中卡拉麦里-三个泉东-三个泉断裂带控制了陆梁隆起的长期活动和构造演化, 首次系统地论述了盆地内部基底的南北向断裂构造。在对各沉积盖层断裂分析的基础上对沉积盖层中的断裂系统进行了叠加分析, 结果发现, 盖层中的断裂密集带与深部断裂的长期活动密切相关, 它们形成了以深部断裂为树干, 以盖层断裂为枝体的深浅部断裂构造组合; 深部断裂构造对现今地貌起着控制作用。

Abstract: The periphery fault structures and spatial distributions in Junggar basin are analyzed. Based on the 3D structural analysis of folded basement, crystal basement and Moho, the EW and SN trending lithospheric fracture in this basin are identified, in which the Kelameili-Eastern Sangequan-Sangequan fault belt controls the tectonic evolution of Luliang uplift. The SN trend faults in basement of the basin are firstly discussed. The analysis of superposed fault system in different sedimentary cap rocks shows that the dense fault belts are closely associated with long-term activities of deep faults, which form the shallow-deep fault configuration. The present landform is mainly controlled by the deep fault structures.

Key words: Junggar basin, periphery fault, basement fault, cover fault
