【摘要】 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。更多还原

【Abstract】 Kuqa rejuvenation foreland thrust belt is devided into five structural zones from north to south as follows: 1. North margin thrusting cyptowedging zone, 2. Stike anticline zone, 3. North linear anticline zone, 4. Baichen pigyback depression, 5. Qiulitag frontier zone. They composed a southward thrust wedge which is about 50 km width and more than 200 km long. There are varied structural styles in the structural zones, i. e. fault bend fold, fault propagation fold, detachment fold, hybrid fault propagationdetachment fold and duplex thrust structure. There are different geological ages of growth strata in antichne limbs of different structural zones, showing the different emplacement ages of the structural zones. The Stike anticline zone was formed since Miocene (24. 5Ma). The North linear anticline zone was since middle Miocene (16.9Ma). The Dawanqi anticline in Baichen depression was since late Pliocene (3. 9Ma),and Yaken anticline in Qiulitak frontier zone was since early Pleistocene (1.8Ma). Therefore the deformation ages were younging southward from Miocene to Quaternary. The Kuqa rejuvenation foreland thrust belt is resulted from the remote tectonic effect in continent interior by the continent to continent collision of Indian to Tibetian continent.更多还原
