断层相关褶皱理论在准噶尔盆地南缘山前带构造研究的应用

Application of the geometry of fault-related folding to the southern Junggar Basin

利用断层相关褶皱的构造几何分析方法,对准噶尔盆地南缘山前复杂构造带内基干地震剖面进行了构造解析,搭建了中、东段的构造轮廓和构造组合样式,认为东段阜康断裂带主要表现为至地表的推覆逆掩。由于位移量大部分转移至地表,阜康断裂带的前陆部分无喜山期构造带;西段造山带内的挤压往前陆方向传递过程中以前列式不断释放其位移量,造成在纵向上呈现三排主要的断层相关褶皱带。根据正演平衡地质剖面制作技术对山前复杂构造区地震剖面反射波的构造识别进行了模拟与探讨。

Using the structural geometric model of fault-related folding, we constructed the geological outline of the southern Junggar Basin near north Tianshan. The seismic across-reflect in the complex structural region can be recognized structurally by forward balanced geological cross-section simulating. In the complex structural region, the key of seismic section interpretation built the structure model and structural geometric analysis, in those processes balanced section can take the interpreter reasonable structural explain project.
