库车再生前陆逆冲带自北而南分为以下5个构造带:①北部边缘冲断──隐伏构造楔;②斯的克背斜带;③北部线 性背斜带;④拜城背驮凹陷;⑤丘里塔格前缘带。全体形成前锋向南的冲断变形楔。各构造带中发耷多种型式的断坪/断坡 台阶状逆断层相关褶皱:断层转折褶皱、断层传播褶皱、滑脱褶皱、断层传播──滑脱混生褶皱、双重逆冲构造。在不同构 造带发育不同时代的生长地层,指示了各构造带不同的构造变形年代。斯的克背斜带变形时期最早,始于中新世 (24.5Ma),北部线性为形始于中新世中期(16.9Ma),拜城凹陷的大宛其背变形始于上新世中期(3.9Ma),丘里塔格前锋 带的亚肯背斜变形始于更新世早期(1.8Ma).可见构造变形自北向南自中新世至第四纪逐渐变新。这一道冲带是印-藏板 块陆-陆碰撞远距离构造效应的内陆变形产物。
The Kuqa regenerative foreland thrust belt is divided into five tectonic belts from north to south: ① northern margin thrust-buried tectonic wedge; ② Sri gram anticline belt; ③ northern linear anticline belt; ④ Baicheng back Pack depression; ⑤ Qurlitag front band. The formation of forward thrust south of the deformation of the wedge. Various types of faulted / step-shaped reverse fault-related folds in various tectonic belts: fault fold folds, fault propagation folds, slippage folds, fault propagation-slipping mixed folds, and dual thrust structures. In different tectonic belts, growth stratums of different ages are developed, indicating different tectonic deformation ages of each structural belt. The Skegsk anticline began its deformation in the Miocene (24.5Ma) with its northern linear shape starting from the middle Miocene (16.9Ma) The mid-to mid-Cenozoic (3.9Ma), the Yakin anticline deformation of the Quriratega striker began in the early Pleistocene (1.8Ma). Visible structural deformation from north to south from the Miocene to Quaternary gradually become new. This bluffing zone is the inland deformation product of the long-range tectonic effect of the Indian-Tibetan plate continent-continent collision.
