库车褶皱冲断带克拉苏三角带的位移转换构造

根据对库车褶皱冲断带的地面地质调查和地震反射剖面的解释表明，库车褶皱冲断带克拉苏三角带发育垂直构造走向的位移转换构造。在地面上，位移转换构造分别表现为库姆格列木、巴什基奇克和开依雷艾肯背斜以及吐孜麻扎、喀桑托开和吉迪克背斜构造的走向侧接构造样式；在地下表现为库—巴冲断层、喀桑托开冲断层的断距的反接关系。位移转换构造发育的动力学背景可能与南天山重力滑动构造有关。

Displacement Transfer Zone of Kelasu Triangle Zone, Kuqa Thrust-and-Fold Belts in Tarim Basin

The field observation and seismic data interpretation reveal that the displacement transfer zone is developed in the Kelasu triangle zone, Kuqa thrust-and-fold belts. The displacement transfer zone appears as relay ramps of the Kumugeliemu anticlines, Bashijiqike anticlines, Kaiyileiaiken anticlines to the north and Tuzimazha anticlines, Kasangtuokai anticlines, and Jidike anticlines to the south on the surface, respectively. Under the subsurface, it appears as throw deviation of Kumugeliemu-Bashijiqike thrusts and Kasangtuokai thrusts. Its dynamic occurrence may be related to the gravitational slide structures along the southern Chinese Tianshan front ranges.
